SIMPLE ULCER OF THE STOMACH.

BY W. H. WELCH, M.D.

---

DEFINITION.—Simple ulcer of the stomach is usually round or oval. When of recent formation it has smooth, clean-cut, or rounded borders, without evidence of acute inflammation in its floor or in its borders. When of long duration it usually has thickened and indurated margins. The formation of the ulcer is usually attributed, in part at least, to a disturbance in nutrition and to a subsequent solution by the gastric juice of a circumscribed part of the wall of the stomach. The ulcer may be latent in its course, but it is generally characterized by one or more of the following symptoms: pain, vomiting, dyspepsia, hemorrhage from the stomach, and loss of flesh and strength. It ends frequently in recovery, but it may end in death by perforation of the stomach, by hemorrhage, or by gradual exhaustion.

SYNONYMS.—The following epithets have been employed to designate this form of ulcer: simple, chronic, round, perforating, corrosive, digestive, peptic; ulcus ventriculi simplex, s. chronicum, s. rotundum, s. perforans, s. corrosivum, s. ex digestione, s. pepticum.

HISTORY.—It is only since the description of gastric ulcer by Cruveilhier in the year 1830 that especial attention has been paid to this disease.

In the writings of the ancients only vague and doubtful references to ulcer of the stomach are found (Galen, Celsus). It is probable that cases of this disease were described under such names as passio cardiaca, gastrodynia, hæmatemesis, and melæna.

After the revival of medicine in the sixteenth century, as post-mortem examination of human bodies was made with greater frequency, the existence of ulcers and of cicatrices in the stomach could not escape attention. But only isolated and curious observations of gastric ulcer are recorded up to near the end of the eighteenth century. One of the earliest recorded unmistakable cases of perforating ulcer was observed by John Bauhin, and is described in the Sepulchretum of Bonetus, published in 1679. Other cases belonging to this period were described by Donatus, Courtial, Littré, Schenck, and Margagni.¹

¹ References to these and to other cases may be found in Lebert's Krankheiten des Magens, Tübingen, 1878, p. 180 et seq.

To Matthew Baillie unquestionably belongs the credit of having first accurately described, in 1793, the anatomical peculiarities of simple gastric ulcer.² At a later date he published three good engravings of this disease.³ Baillie's concise and admirable description of the morbid anatomy of gastric ulcer was unaccompanied by clinical data, and seems to have had little or no influence in directing increased attention to this disease.

A valuable account of the symptoms of gastric ulcer was given by John Abercrombie in 1824.⁴ Nearly all of the symptoms now recognized as belonging to this affection may be found in his article. He knew the latent causes of the disease, the great diversity of symptoms in different cases, and the modes of death by hemorrhage, by perforation, and by asthenia. He regarded ulcer simply as a localized chronic inflammation of the stomach, and did not distinguish carefully between simple and cancerous ulceration.

See also, by the same author, Pathological and Practical Researches on Diseases of the Stomach, etc.—an excellent work which passed through several editions.

Cruveilhier,⁵ in the first volume of his great work on Pathological Anatomy, published between the years 1829 and 1835, for the first time clearly distinguished ulcer of the stomach from cancer of the stomach and from ordinary gastritis. He gave an authoritative and full description of gastric ulcer from the anatomical, the clinical, and the therapeutical points of view.

Next to Cruveilhier, Rokitansky has had the greatest influence upon the modern conception of gastric ulcer. In 1839 this pathologist gave a description of the disease based upon an analysis of 79 cases.⁶ The anatomical part of his description has served as the model for all subsequent writers upon this subject.

⁶ Rokitansky, Oesterreich. med. Jahrb., 1839, Bd. xviii. (abstract in Schmidt's Jahrb., Bd. 25, p. 40).

Since the ushering in by Cruveilhier and by Rokitansky of the modern era in the history of gastric ulcer, medical literature abounds in articles upon this disease. But it cannot be said that the importance of these works is at all commensurate with their number or that they have added very materially to the classical descriptions given by Cruveilhier and by Rokitansky. Perhaps most worthy of mention of the works of this later era are the article by Jaksch relating to symptomatology and diagnosis, that of Virchow pertaining to etiology, the statistical analyses by Brinton, and the contributions to the treatment of the disease by Ziemssen and by Leube.⁷ In 1860, Ludwig Müller published an extensive monograph upon gastric ulcer.⁸

Wochenschr., Nos. 26, 27, 1857; Brinton, On the Pathology, Symptoms, and Treatment of Ulcer of the Stomach, London, 1857; V. Ziemssen, Volkmann's Samml. klin. Vorträge, No. 15, 1871; Leube, Ziemssen's Handb. d. spec. Path. u. Therap., Bd. vii., Leipzig, 1878.

ETIOLOGY.—We have no means of determining accurately the average frequency of simple gastric ulcer. The method usually adopted is to observe the number of cases in which open ulcers and cicatrices are found in the stomach in a large number of autopsies. But this method is open to two objections. The first objection is, that scars in the stomach, particularly if they are small, are liable to be overlooked or not to be noted in the record of the autopsy unless special attention is directed to their search. The second objection is, that it is not proven that all of the cicatrices found in the stomach are the scars of healed simple ulcers, and that, in fact, it is probable that many are not. In consequence of these defects (and others might be mentioned) this method is of very limited value, although it is perhaps the best which we have at our disposal.

In 32,052 autopsies made in Prague, Berlin, Dresden, Erlangen, and Kiel,⁹ there were found 1522 cases of open ulcer or of cicatrix in the stomach. If all the scars be reckoned as healed ulcers, according to these statistics gastric ulcer, either cicatrized or open, is found in about 5 per cent. of persons dying from all causes.

⁹ The Prague statistics embrace 11,888 autopsies, compiled from the following sources: 1, Jaksch, Prager Vierteljahrschr., vol. iii.; 2, Dittrich, ibid., vols. vii., viii., ix., x., xii., xiv.; 3, Willigk, ibid., vol. li.; 4, Eppinger, ibid., vol. cxvi.

The Berlin statistics are to be found in dissertations by Plange (abstract in Virchow's Archiv, vol. xviii.), by Steiner, and by Wollmann (abstracts in Virchow und Hirsch's Jahresbericht, 1868), and by Berthold (1883).

The Dresden statistics are in a dissertation by Stachelhausen (Würzburg, 1874), referred to by Birch-Hirschfeld, Lehrb. d. path. Anat., Bd. ii. p. 837, Leipzig, 1877.

The Erlangen statistics are reported by Ziemssen in Volkmann's Samml. klin. Vorträge, No. 15.

The Kiel report is in an inaugural dissertation by Greiss (Kiel, 1879), referred to in the Deutsche med. Wochenschr., Feb. 4, 1882, p. 79.

So far as possible, duodenal ulcers have been excluded. Only those reports have been admitted which include both open ulcers and cicatrices.

It is important to note the relative frequency of open ulcers as compared with that of cicatrices. In 11,888 bodies examined in Prague, there were found 164, or 1.4 per cent., with open ulcers, and 373, or 3.1 per cent., with cicatrices. Here scars were found about two and one-fourth times as frequently as open ulcers. The observations of Grünfeld in Copenhagen show that when especial attention is given to searching for cicatrices in the stomach, they are found much more frequently than the figures here given would indicate.¹⁰ It would be a moderate estimate to place the ratio of cicatrices to open ulcers at 3 to 1.

¹⁰ Grünfeld (abstract in Schmidt's Jahrb., Bd. 198, p. 141, 1883) in 1150 autopsies found 124 cicatrices in the stomach, or 11 per cent., but in only 450 of these cases was his attention especially directed to their search, and in these he found 92 cases, or 20 per cent., with scars. Grünfeld's statistics relate only to persons over fifty years of age. Gastric ulcer, moreover, is extraordinarily common in Copenhagen.

The inexact nature of the ordinary statistics relating to cicatrices is also evident from the fact that in the four collections of cases which comprise the Prague statistics the percentage of open ulcers varies only between 0.81 and 2.44, while the percentage of cicatrices varies between 0.89 and 5.42.

The statistics concerning the average frequency of open ulcers are much more exact and trustworthy than those relating to cicatrices. It may be considered reasonably certain that, at least in Europe, open gastric ulcers are found on the average in from 1 to 2 per cent. of persons dying from all causes.¹¹

¹¹ If in this estimate were included infants dying during the first days of life, the percentage would be much smaller.

It is manifestly impossible to form an accurate estimate of the frequency of gastric ulcer from the number of cases diagnosed as such during life, because the diagnosis is in many cases uncertain. Nevertheless, estimates upon this basis have practical clinical value. In 41,688 cases constituting the clinical material of Lebert¹² in Zurich and in Breslau between the years 1853 and 1873, the diagnosis of gastric ulcer was made in 252 cases, or about ²/3 per cent.

¹² Lebert, op. cit., p. 196.

Of 1699 cases of gastric ulcer collected from various hospital statistics¹³ and examined post-mortem, 692, or 40 per cent., were in males, and 1007, or 60 per cent., were in females. The result of this analysis makes the ratio 2 males to 3 females.

¹³ These statistics include the previously-cited Prague, Berlin, Dresden, and Erlangen cases so far as the sex is given, and in addition the returns of Rokitansky, op. cit.; Starcke (Jena), Deutsche Klinik, 1870, Nos. 26-29; Lebert, op. cit.; Chambers, London Journ. of Med., July, 1852; Habershon, Dis. of the Abdomen, 3d ed.; Moore, Trans. of London Path. Soc., 1880; and the Munich Hospital, Annalen d. städt. Allg. Krankenh. zu München, vols. i. and ii.

Only series of cases from the post-examinations of a number of years have been admitted. It is an error to include isolated cases from journals, as Brinton has done, because an undue number of these are cases of perforation, which is a more common event in females than in males. Thus, of 43 cases of gastric ulcer presented to the London Pathological Society since its foundation up to 1882, 19, or 44 per cent., were cases of perforation. In my cases are included a few duodenal ulcers not easily separated from the gastric ulcers in the compilation.

In order to determine from post-mortem records the age at which gastric ulcer most frequently occurs, all cases in which only cicatrices are found should be excluded, because a cicatrix gives no evidence as to the age at which the ulcer existed.

The following table gives the age in 607 cases of open ulcer collected from hospital statistics¹⁴ (post-mortem material):

Age.	1-10.	10-20.	20-30.	30-40.	40-50.	50-60.	60-70.	70-80.	80-90.	90-100.	Over 100.
No. of cases.	1	32	119	107	114	108	84	35	6	...	1
Totals.	33		226		222		119		7

From this table it is apparent that three-fourths of the cases are found between the ages of twenty and sixty, and that the cases are distributed with tolerable uniformity between these four decades. The largest number of cases is found between twenty and thirty. The frequency of gastric ulcer after sixty years diminishes, although it remains quite considerable, especially in view of the comparatively small number of those living after that period.

¹⁴ The sources of these statistics are the same as those of the statistics relating to sex in the preceding foot-note. The age in the Erlangen cases of open ulcer is given by Hauser (Das chronische Magengeschwür, p. 191, Leipzig, 1883). It is evident that only about two-fifths of the cases could be utilized, partly because in some the age was not stated, but mainly on account of the necessity of excluding scars—a self-evident precaution which Brinton did not take.

The probability that many cases of ulcer included in the above table existed for several years before death makes it desirable that estimates as to the occurrence of the disease at different ages should be made also from cases carefully diagnosed during life, although the diagnosis must necessarily be less certain than that in the post-mortem records. The best statistics of this character which we possess are those of Lebert, from whose work the following table has been compiled:

Age in 252 Cases of Gastric Ulcer diagnosed during Life by Lebert.¹⁵

Age.	5-10.	11-20.	21-30.	31-40.	41-50.	51-60.	61-70.
No. of cases.	1	24	87	84	34	17	5
Totals.	25		171		51		5
Per cent.	9.92		67.85		20.24		1.99

Of these cases, nearly seven-tenths were between twenty and forty years of age—a preponderance sufficiently great to be of diagnostic value.¹⁶

¹⁵ Op. cit., p. 199. Of these cases, 19 were fatal, and the diagnosis was confirmed after death. All of the cases were studied by Lebert in hospitals in Zurich and Breslau.

¹⁶ In my opinion, clinical experience is more valuable than are post-mortem records in determining the age at which gastric ulcer most frequently develops. In support of this opinion are the following facts: In many cases no positive conclusions as to the age of the ulcer can be drawn from the post-mortem appearances, and sufficient clinical history is often wanting; a considerable proportion of the cases of gastric ulcer do not terminate fatally with the first attack, but are subject to relapses which may prove fatal in advanced life; in most general hospitals the number of patients in advanced life is relatively in excess of those in youth and middle age. By his faulty method of investigating this question, Brinton came to the erroneous conclusion that the liability to gastric ulcer is greatest in old age—a conclusion which is opposed to clinical experience.

The oldest case on record is the one mentioned by Eppinger,¹⁷ of an old beggar whose age is stated at one hundred and twenty years.

¹⁷ Prager Vierteljahrschrift, Bd. 116.

The occurrence of simple ulcer of the stomach under ten years of age is extremely rare. Rokitansky, with his enormous experience, said that he had never seen a case under fourteen years.¹⁸ There are recorded, however, a number of cases of gastric ulcer in infancy and childhood, but there is doubt as to how many of these are genuine examples of simple ulcer. Rehn in 1874 analyzed a number, although by no means all, of the reputed cases, and found only six, or at the most seven, which would stand criticism.¹⁹ The age in these seven cases varied between seven days and thirteen years. In one case (Donné) a cicatrix was found in the stomach of a child three years old. Since the publication of Rehn's article at least four apparently genuine cases have been reported—namely, one by Reimer in a child three and a half years old; one by Goodhart in an infant thirty hours after birth; one by Eröss in a girl twelve years old suffering from acute miliary tuberculosis, in whom the ulcer perforated into the omental sac; and one by Malinowski in a girl ten years of age.²⁰

Rehn does not mention Buzzard's case of perforating ulcer in a girl nine years old (Trans. London Path. Soc., vol. xii. p. 84, 1861). See also Chvostek's case of round ulcer in a boy (Arch. f. Kinderheilk., 1881-82) and Wertheimber's case of recovery from gastric ulcer in a girl ten years old (Jahrb. f. Kinderheilk., Bd. xix. p. 79).

The mean age at which gastric ulcer develops is somewhat higher in the male than in the female. This is apparent from the following collection of 332 cases of open ulcer in which both age and sex are given:²¹

Age.	10-20.	20-30.	30-40.	40-50.	50-60.	60-70.	70-80.	80-90.	90-100.	Over 100.	Total.
Males.	9	33	44	39	37	20	5	1	...	1	189
Females.	13	35	25	25	18	18	9	...	...	...	143

In males the largest number of cases is found between thirty and forty years, and in females between twenty and thirty. In males 54½ per cent. of the cases occur after forty years of age, and in females 48.9 per cent.

²¹ These cases are obtained from the same sources as those of the first table (page [483]).

The relation between age and perforation of gastric ulcer will be discussed in connection with this symptom.

The conclusions concerning the age of occurrence of gastric ulcer may be recapitulated as follows: Simple ulcer of the stomach most frequently develops in the female between twenty and thirty, and in the male between thirty and forty. At the post-mortem table it is found with almost equal frequency in the four decades between twenty and sixty, but clinically it appears with greatly diminished frequency after forty years of age. In infancy and early childhood simple ulcer of the stomach is a curiosity.

We have no positive information as to the influence of climate upon the production of gastric ulcer. The disease seems to be somewhat unequal in its geographical distribution, but the data bearing upon this point are altogether insufficient.

According to the returns of Dahlerup and of Grünfeld, gastric ulcer is unusually common in Copenhagen.²² According to Starcke's report²³—which, however, is not based upon a large number of cases—the percentage is also unusually high in Jena. Sperk says that gastric ulcer is very common in Eastern Siberia.²⁴ Palgrave gives a high percentage of its occurrence in Arabia.²⁵ The disease is less common in France than in England or in Germany,²⁶ and in general appears to be more common in northern than in southern countries. The statement of DaCosta²⁷ coincides with my own impression that gastric ulcer is less common in this country than in England or in Germany. I have found 6 cases of open ulcer of the stomach in about 800 autopsies made by me in New York.

²² Dahlerup in Copenhagen (abstract in Canstatt's Jahresbericht, 1842) found 26 cases in 200 autopsies (13 per cent.) made in the course of a year and a half. Grünfeld (loc. cit.) found 124 cicatrices in 1150 autopsies (11 per cent.).

²³ Starke (loc. cit.) found 39 cases in 384 autopsies (10 per cent.); cf. also Müller, Jenaische Zeitschr., v. 1870.

²⁷ Medical Diagnosis, 5th ed., Philada., 1881. Keating expresses the same opinion in the Proc. of Path. Soc. of Philadelphia, vol. i. p. 142.

In 444,564 deaths in New York City from 1868 to 1882, inclusive, ulcer of the stomach was assigned as the cause of death only in 410 cases. Little value can be assigned to these statistics as regards a disease so difficult of diagnosis.

Gastric ulcer is more common among the poor than among the rich. Anxiety, mental depression, scanty food, damp dwellings, insufficient exercise, and exposure to extreme cold are among the depressing influences which have been assigned as predisposing causes of gastric ulcer, but without sufficient proof.

The comparative frequency of gastric ulcer among needlewomen, maidservants, and female cooks has attracted the attention of all who have had large opportunity for clinical observation.

Pressure upon the pit of the stomach, either by wearing tight belts or in the pursuit of certain occupations, such as those of shoemaking, of tailoring, and of weaving, is thought by Habershon and others to predispose to ulcer of the stomach.²⁸

²⁸ Bernutz found gastric ulcer in a turner in porcelain, and learned that other workmen in the same factory had vomited blood. He thinks that in this and in similar occupations heavy particles of dust collecting in the mouth and throat may be swallowed with the saliva, and by their irritation cause gastric ulcer (Gaz. des Hôpitaux, June 18, 1881).

Vomiting of blood has been known in several instances to affect a number of members of the same family, but beyond this unsatisfactory evidence there is nothing to show hereditary influence in the origin of gastric ulcer.

In a few cases injury of the region of the stomach, as by a fall or a blow, has been assigned as the cause of ulcer. The efficacy of this cause has been accepted by Gerhardt,²⁹ Lebert, Ziemssen, and others. In many of the cases in which this cause has been assigned the symptoms of ulcer appeared so long after the injury that it is doubtful whether there was any connection between the two.

²⁹ "Zur Aetiologie u. Therapie d. runden Magengeschwürz," Wiener med. Presse, No. 1, 1868.

That loss of substance in the mucous membrane of the stomach may be the result of injury directly or indirectly applied to this organ cannot admit of question. But it is characteristic of these traumatic ulcers that they rapidly heal unless the injury is so severe as to prove speedily fatal. Thus, Duplay³⁰ relates three cases in which pain, vomiting, repeated vomiting of blood, and dyspepsia followed contusions of the region of the stomach. But these traumatic cases, which for a time gave the symptoms of gastric ulcer, recovered in from two weeks to two months, whereas the persistence of the symptoms is a characteristic of simple ulcer.³¹

³⁰ "Contusions de l'Estomac," Arch. gén. de Méd., Sept., 1881.

³¹ In a case reported by Potain, however, the symptoms of ulcer appeared immediately after injury to the stomach, and continued up to the time of death (Gaz. hebdom., Sept. 12, 1856).

In the same way, ulcers of the stomach produced by corrosive poisons as a rule soon cicatrize, unless death follows after a short time the action of the poison. That corrosive ulcers may, however, be closely allied to simple ulcers is shown by an interesting case reported by Wilson Fox,³² in which the immediate effects of swallowing hydrochloric acid were recovered from in about four days, but death resulted from vomiting of blood two weeks after. At the autopsy the source of the hemorrhage was found in an ulcer of the pyloric region of the stomach. An equally striking case is reported by Williams.³³ A boy who suffered severely for three or four days after drinking some strong mineral acid recovered, so that he ate and drank as usual. Two months afterward he died suddenly from perforation of a gastric ulcer.

³² Trans. of the Path. Soc., vol. xix. p. 239, London, 1868.

³³ The Lancet, April 9, 1842.

While, then, it would be a great error to identify traumatic and corrosive ulcers of the stomach with simple ulcer, it is possible that either may become chronic if associated with those conditions of the stomach or of the constitution, for the most part unknown to us, which prevent the ready healing of simple ulcer.

Gastric ulcer is often associated with other diseases, but it occurs also uncomplicated in a large number of cases. Most of the diseases with which it has been found associated are to be regarded simply as coincident or complicating affections; but as some of them have been thought to cause the ulcer, they demand consideration in this connection.

The large share taken by pulmonary phthisis in deaths from all causes renders this disease a frequent associate of gastric ulcer. It is probable that the lowered vitality of phthisical patients increases somewhat their liability to gastric ulcer. Moreover, it would not be strange if gastric ulcer, as well as other exhausting diseases, such as diabetes and cancer, diminished the power of resisting tuberculous infection. Genuine tuberculous ulcers occur rarely in the stomach, but they are not to be identified with simple ulcer.

There is no proof that amenorrhoea or other disorders of menstruation exert any direct influence in the production of gastric ulcer, although Crisp went so far as to designate certain cases of gastric ulcer as the menstrual ulcer.³⁴ Nevertheless, amenorrhoea is a very common symptom or associated condition in the gastric ulcer of females between sixteen and thirty years of age.

³⁴ The Lancet, Aug. 5, 1843.

Chlorosis and anæmia, especially in young women, favor the development of gastric ulcer, but that there is no necessary relation between the two is shown by the occurrence of ulcer in those previously robust. Moreover, it is probable that in some cases in which the anæmia has been thought to precede the ulcer it has, in fact, been a result rather than a cause of the ulcer.

Especial interest attaches to the relation between gastric ulcer and diseases of the heart and of the blood-vessels, because to disturbances in the circulation in the stomach the largest share in the pathenogenesis of ulcer has been assigned by Virchow. As might be expected, valvular lesions of the heart and atheroma of the arteries are not infrequently found in elderly people who are the subjects of gastric ulcer. A small proportion of cases of ulcer has been associated also with other diseases in which the arteries are often abnormal, such as with chronic diffuse nephritis, syphilis, amyloid degeneration, and endarteritis obliterans. But, after making the most generous allowance for the influence of these diseases in the causation of ulcer of the stomach, there remains a large number of cases of ulcer in which no disease of the heart or of the arteries has been found.³⁵ Gastric ulcer develops most frequently between fifteen and forty years of age, a period when arterial diseases are not common. Changes in the blood-vessels of the stomach will be described in connection with the morbid anatomy of gastric ulcer.

³⁵ From Berlin are reported the largest number of cases of gastric ulcer associated with diseases of the circulatory apparatus; thus, by Berthold 170 out of 294 cases, and by Steiner 71 out of 110 cases of ulcer. Endocarditis and arterial atheroma (present in one-third of Berthold's cases of ulcer) form the largest proportion of these diseases.

Chronic passive congestion of the stomach in cases of cirrhosis of the liver, direct injury to the mucous membrane of the stomach by parasites in trichinosis, hemorrhage into the coats of the stomach in scorbutus and in dementia paralytica, persistent vomiting in pregnancy, and anæmia induced by prolonged lactation, have each been assigned as causes in a few cases of gastric ulcer, but they are not associated with gastric ulcer in enough cases to make their causative influence at all certain.

Galliard assigns diabetes mellitus as the cause in one case of gastric ulcer.³⁶

³⁶ Clin. méd. de la Pitié, Paris, 1877, p. 77.

Rokitansky attributed some cases of gastric ulcer to intermittent fever.

Those who believe in the inflammatory origin of ulcer of the stomach think that chronic gastritis is an important predisposing cause.

The abuse of alcohol is admitted as an indirect cause of gastric ulcer by the majority of writers.

Lastly, burns of the skin, which are an important factor in the etiology of duodenal ulcers, have been followed only in a very few instances by ulcer of the stomach.

The direct causes of ulcer of the stomach, concerning which our positive knowledge is very limited, will be considered under the pathenogenesis of the disease.

SYMPTOMATOLOGY.—The following classes of cases of gastric ulcer may be distinguished:

First: Gastric ulcer may give rise to no symptoms pointing to its existence, and be found accidentally at the autopsy when death has occurred from some other disease. This latent course is most frequent with gastric ulcers complicating chronic wasting diseases, such as tuberculosis, and with gastric ulcers in elderly people.

Second: Gastric ulcer may give rise to no marked symptoms before profuse hemorrhage from the stomach or perforation of the stomach, resulting speedily in death, occurs. Acute ulcers in anæmic females from fifteen to thirty years of age are those most liable to perforate without previous symptoms.

Third: Gastric ulcer may occasion only the symptoms of chronic gastritis, or of functional dyspepsia, or of purely nervous gastralgia, so that its diagnosis is impossible. In this class of cases after a time characteristic symptoms may develop. Here, too, sudden death may occur from hemorrhage or from perforation.

Fourth: In typical cases characteristic symptoms are present, so that the diagnosis can be made more or less positively. These symptoms are pain, and hemorrhage from the stomach, associated usually with vomiting and disturbances of digestion.

The different symptoms of gastric ulcer will now be described.

Of all the symptoms, pain is the most constant and is often the first to attract attention. It is absent throughout the disease only in exceptional cases. In different cases, and often in the same case at different times, the pain varies in its quality, its intensity, its situation, its duration, and in other characteristics.

The kind of pain which is most characteristic of gastric ulcer is severe paroxysmal pain strictly localized in a circumscribed spot in the epigastrium, coming on soon after eating, and disappearing as soon as the stomach is relieved of its contents.

More common, although less characteristic, than the strictly localized pain are paroxysms of severe pain, usually called cardialgic³⁷ or gastralgic, diffused over the epigastrium and often spreading into the surrounding regions. This is like the neuralgic pain of nervous gastralgia, which is not infrequent in chlorotic and hysterical females. The pain may be so intense as to induce syncope, or even convulsions, in very sensitive patients.

³⁷ There is much confusion as to the meaning of the term cardialgia. With most English and American writers it signifies heartburn, while continental writers understand by cardialgia the severe paroxysms of epigastric pain which we more frequently call gastralgia.

The strictly localized pain is probably caused by direct irritation confined to the nerves in the floor of the ulcer. In the diffuse gastralgic attacks the irritation radiates or is reflected to the neighboring nerves, and sometimes to those at a distance.

In most cases of gastric ulcer localized epigastric pain and diffuse gastralgic paroxysms are combined.

The painful sense of oppression and fulness in the epigastrium which is felt in many cases of gastric ulcer after eating is simply a dyspeptic symptom, and is probably referable to an associated chronic catarrhal gastritis. This dyspeptic pain is of little value in diagnosis.

Most subjects of gastric ulcer feel in the intervals between the paroxysms a more or less constant dull pain, or it may be only a sense of uneasiness, in the epigastrium. When sharp epigastric pain is felt continuously, it is usually inferred that the ulcer has extended to the peritoneum and has caused a circumscribed peritonitis, but this inference is not altogether trustworthy.

The quality of the pain caused by gastric ulcer is described variously as burning, gnawing, boring, less frequently as lancinating.

More important than the quality is the situation of the pain. The situation of the localized pain is usually at or a little below the ensiform cartilage. It may, however, be felt as low as the umbilicus or it may deviate to the hypochondria. In addition to pain in the epigastrium (point épigastrique), Cruveilhier called attention to the frequent presence of pain in the dorsal region (point rachidien). The dorsal pain, which may be more severe than the epigastric, is sometimes interscapular, and sometimes corresponds to the lowest dorsal or to the upper lumbar vertebræ. It is usually a little to the left of the spine. The pain is often described as extending from the pit of the stomach through to the back.

According to Brinton, the situation of the localized pain gives a clue to the situation of the ulcer, pain near the left border of the ensiform cartilage indicating ulcer near the cardiac orifice, pain in the median line and to the right of this indicating ulcer of the pyloric region, and pain in the left hypochondrium indicating ulcer of the fundus. It does not often happen that the pain remains so sharply localized as to make possible this diagnosis, even if the situation of the pain were a safe guide.

Of the various circumstances which influence the severity of the pain in gastric ulcer, the most important is the effect of food. Pain usually comes on within a few minutes to half an hour after taking food, although it may appear immediately after ingestion or be delayed for an hour or more. The pain continues until the stomach is relieved of its contents by vomiting or by their passage into the duodenum. It is unsafe to attempt to diagnose the position of the ulcer merely from the length of time which elapses between the ingestion of food and the onset of pain. It has sometimes been noticed that as improvement progresses pain comes on later and later after eating. As might naturally be expected, coarse, indigestible, imperfectly-masticated food, sour and spirituous liquids, and hot substances are more irritating than bland articles of diet. In some exceptional cases the ingestion of even coarse food, instead of aggravating, has had no effect upon the pain, or at least for the time being has even relieved it.

External pressure usually increases the intensity of the pain of gastric ulcer; in rare instances pressure relieves the pain.

Rest and the recumbent posture as a rule alleviate the pain of ulcer of the stomach. The position of the patient may affect the severity of the pain in a more striking way. It may naturally be supposed that that posture is most agreeable which removes from the ulcer the weight of the food during digestion. Hence it was claimed by Osborne³⁸ that the site of the ulcer could often be inferred from the effect of posture on the pain. Thus, relief in the prone position would indicate ulcer of the posterior wall; relief in the supine position, ulcer of the anterior wall; relief on the left or on the right side, ulcer of the pyloric or of the cardiac region respectively. As ulcer of the posterior wall is the most frequent, relief should be obtained oftener by bending forward or by lying on the face than in the supine position. Experience has shown that the influence of posture on the pain is not a safe guide in diagnosing the location of the ulcer.

³⁸ Jonathan Osborne, Dublin Journal of Medical Science, vol. xxvii. p. 357, 1845.

Mental emotions—particularly anxiety and anger—fatigue, even moderate exercise, exposure to cold, and the menstrual molimen may each cause exacerbations of pain in some cases of gastric ulcer.

Tenderness on pressure is a common symptom of gastric ulcer. A localized point of tenderness may be discovered even when the subjective pain is not localized. Pain sometimes follows pressure not immediately, but after a brief interval. A fixed point of tenderness can often be determined when the stomach is empty more accurately than when it is full. The tender spot can sometimes be covered by the finger's end. In searching for a point of tenderness it should be remembered that many persons are very sensitive to pressure in the epigastrium, and also that pressure is not without danger to those who are the subjects of gastric ulcer. Not only may pressure induce paroxysms of pain, but it may cause even rupture of the ulcerated walls of the stomach.³⁹ Hence pressure should be cautiously employed and should not be often repeated.

³⁹ Dalton has reported a case in which perforation of a gastric ulcer occurred while the patient was subjected in a water-cure establishment to kneading of the abdomen to relieve his flatulence (Trans. N.Y. Path. Soc., vol. i. p. 263.)

In some cases of gastric ulcer pain is felt in regions at a distance from the stomach. The most frequent of these so-called radiation neuralgias are—neuralgia of the lower intercostal spaces, combined sometimes with hyperæsthesia or with analgesia of the affected region, pain in the right shoulder (perhaps due to adhesions between the stomach and the liver or the diaphragm), pain in the left shoulder, and pain in the loins. In a case of ulcer reported by Traube terminating in perforation the sole complaint, besides loss of appetite and retching, had been difficulty in breathing and oppression in the chest. These symptoms, which may be combined with gastralgic paroxysms, are referred by Traube to transference of the irritation from the gastric to the pulmonary filaments of the pneumogastric nerve.⁴⁰

⁴⁰ Deutsche Klinik, 1861, No. 10. These symptoms evidently correspond to the vagus neurosis described by Rosenbach, in which, as the result of reflex irritation of the pneumogastric nerve in the stomach, occur difficulty in breathing, oppression in the chest, palpitation, arhythmical action of the heart, and epigastric pulsation (Deutsche med. Wochenschr., 1879, Nos. 42, 43).

Sometimes the pain of gastric ulcer intermits for days or even weeks. When the intermission is of considerable duration it is probable that cicatrization has been in progress. It should, however, be remembered that gastralgic attacks may continue even after cicatrization of the ulcer is completed, probably in consequence of compression of nerve-filaments by the cicatricial tissue. Once in a while the pain exhibits a marked periodicity in its appearance. Thus in a case of ulcer ending fatally from hemorrhage the pain came on but once a day, and that with considerable regularity at the same hour. In this case the pain was relieved by taking food.⁴¹ The pain of gastric ulcer may be temporarily relieved by hemorrhage from the stomach, and perhaps by division of the irritated nerve by sloughing (Habershon).

⁴¹ Case reported by Peacock, Rep. of Proceedings of London Path. Soc., vol. i. p. 253, 1847.

The causes of the pain of gastric ulcer are not far to seek. Foremost is the irritation of nerve-filaments exposed by the ulcerative process. The irritation may be by mechanical, chemical, or thermic agencies. With our present imperfect knowledge it is profitless to discuss whether the pneumogastric or the sympathetic nerves are the chief carriers of the abnormal sensations.⁴² In the next place, we may have radiation of the irritation from these nerves to neighboring and even to remote nerves. Furthermore, the extension of the inflammation to the peritoneum and the surrounding parts, and the formation of adhesions, are additional factors in some cases in causing pain. Finally, the great differences in susceptibility to pain manifested by different individuals is to be borne in mind.

⁴² Leven, without sufficient reason, distinguishes two kinds of gastralgic attacks—the one having its point of departure in the pneumogastric, the other in the sympathetic nerve; in the former the pain is associated with dyspnoea and palpitation of the heart; in the latter the pain is deeper, and is accompanied by vaso-motor (?) troubles on one side of the body.

Next to pain, vomiting is the most frequent symptom of gastric ulcer. There is, however, little which is characteristic of ulcer in this symptom, unless the vomited material contains blood. In some cases of gastric ulcer vomiting is the most marked and most distressing symptom of the disease. It may, however, be absent during the whole course of gastric ulcer.

Vomiting occurs most frequently after taking food, and is greatly aggravated by an unregulated diet. Sometimes nearly everything which is taken into the stomach is vomited. The vomiting of mucus or of a thin fluid unmixed with food is indicative only of chronic catarrhal gastritis. Alimentary vomiting, which is more indicative of gastric ulcer, usually occurs not immediately after taking food, but at the acme of a gastralgic attack caused by the food. Soon after the stomach is emptied by one or more acts of vomiting the pain is relieved. The act of vomiting is usually easy, and at times is hardly more than regurgitation of the food. Sometimes the patient experiences an excessively sour taste from the vomit.

Vomiting exhausts the patient by withdrawing nutriment, and when persistent may even cause death from inanition. But in some cases of gastric ulcer, especially in women, the vomiting seems to be mainly a nervous symptom, and even when long continued may be attended by little or no loss of flesh. Evidently, more food is retained in these cases than might be supposed.

There are two evident causes of vomiting in gastric ulcer—namely, chronic catarrhal gastritis, which is a frequent complication, and direct irritation of the nerves in the ulcer. Vomiting due to dilatation of the stomach is oftener a sequel than an immediate symptom of gastric ulcer.

For the diagnosis of gastric ulcer hemorrhage from the stomach is the most important symptom.

The frequency of only the larger hemorrhages can be determined with any degree of exactness. If the blood be effused in small quantity or slowly, it may be discharged solely with the stools and escape detection. Such slight hemorrhages doubtless occur in most cases of gastric ulcer. It is probable that easily-recognized hemorrhages from the stomach occur in about one-third of the cases of gastric ulcer.⁴³ Hemorrhage is absent as a rule in the acute perforating ulcer of the stomach.

⁴³ In consequence of the uncertainty of the diagnosis in cases of gastric ulcer which recover without hemorrhage, the estimates of the frequency of this symptom have a very limited value, and will vary with different observers according to their standard of diagnosis of this disease. Lebert observed gastric hemorrhage in four-fifths of his carefully-studied cases, and in three-fifths of his cases there was profuse hæmatemesis. Brinton estimates that the larger hemorrhages occur in about one-third of the cases. Müller found them in one-fourth of the cases which he analyzed.

In most cases hemorrhage from gastric ulcer is preceded by pain, vomiting, and disturbances of digestion. Antecedent symptoms may, however, be absent, or may be so obscure that no suspicion of ulcer exists until the hemorrhage occurs.

The hemorrhage may be slight, moderate, or excessive in amount (Cruveilhier). The larger hemorrhages are those which are most distinctive of gastric ulcer.

The blood may be vomited, or voided with the stools, or retained in the stomach and the intestines.

As has been remarked, when the hemorrhage is scanty all the blood may escape by the bowel. Sometimes, although much less frequently, blood effused in large quantity is entirely evacuated with the stools. After hæmatemesis more or less blood is discharged by the bowel, sometimes for several days after the vomiting of blood has ceased. Blood which has traversed the whole length of the intestinal canal acquires a tarry consistence and a black or brownish color in consequence of the production of dark-brown hæmatin by the action of the digestive juices upon the hæmoglobin, and in consequence of the formation of black sulphide of iron by the union of hydrogen sulphide in the lower part of the intestine with the iron of the hæmatin. The passage of these black viscid stools is called melæna. Inasmuch as we cannot presume gastric hemorrhage to be absent simply because no blood has been vomited, it is evidently important to examine the stools for blood when the diagnosis of gastric ulcer is obscure, and also in cases of gastric ulcer where there are symptoms of internal hemorrhage not accounted for by blood vomited. It should be remembered that certain drugs, particularly iron and bismuth, may blacken the feces.

In very exceptional cases of gastric ulcer the effusion of a large volume of blood causes sudden death before any of the blood has been vomited. The autopsy shows the stomach and more or less of the small intestine distended with coagulated blood.

Hemorrhage from gastric ulcer is usually made manifest by the vomiting of blood. The quantity of the vomited blood varies from mere traces to several pounds. The color and the consistence of the blood depend upon the quantity effused and the length of time that the blood has remained in the stomach. Blood which has been acted upon by the gastric juice is coagulated, has a grumous consistence, and acquires by the formation of hæmatin out of hæmoglobin a dark-brown color, often compared to that of coffee-grounds. Blood effused in small quantity is usually vomited only with the food, and has usually the coffee-grounds appearance. The patient's condition is not appreciably influenced by this slight loss of blood. A little blood expelled after repeated acts of vomiting has no diagnostic importance. Vomiting usually occurs soon after a large gastric hemorrhage. It is the mechanical distension of the stomach rather than any irritating quality of the blood which causes the vomiting. Blood which is rejected immediately after a large gastric hemorrhage is alkaline, fluid, and of an arterial (rarely of a venous) hue. Often, however, even with large hemorrhages, the blood remains sufficiently long in the stomach to be partly coagulated and to be darkened in color. Ulcer more frequently than any other disease of the stomach causes the vomiting of unaltered blood in large quantity. But this kind of hæmatemesis is not peculiar to simple ulcer. It may occur in other diseases, such as gastric cancer, and coffee-ground vomiting may be associated with ulcer.

Copious hæmatemesis in cases of gastric ulcer appears usually without premonition, or it may be preceded for a day or two by increased pain. Its occurrence is somewhat more common during the digestion of food than in the intervals, but there have been cases of ulcer where the bleeding was favored by an empty stomach and was checked by the distension of the organ with food. The free use of stimulants and violent physical or mental exertion may excite hemorrhage. With the onset of the hemorrhage the patient experiences a sense of warmth and of oppression at the epigastrium, followed by faintness, nausea, and the vomiting of a large quantity of blood. An attack of syncope often causes, at least temporarily, cessation of the hemorrhage. But the thrombus which closes the eroded vessel may easily be washed away, so that the hemorrhage often recurs and continues at intervals for several days, thereby greatly increasing the danger to the patient. Thus, the tendency is for the hemorrhage from gastric ulcer to appear in phases or periods occupying several days.

A single hemorrhage is rarely so profuse as to cause immediate death. More frequently the patient dies after successive hemorrhages. In the majority of cases the hemorrhage is not immediately dangerous to life, but is followed by symptoms of anæmia, more or less profound according to the strength of the patient and the amount of blood lost. Prostration and pallor follow the larger hemorrhages. Dizziness, ringing in the ears, and dimness of vision appear when the patient attempts to leave the recumbent posture. Thirst is often a marked symptom. The pulse is feeble and more frequent than normal. There is often a moderate elevation of temperature (anæmic fever) after profuse hemorrhage. The urine is pale, abundant, and sometimes contains albumen (Quincke). After a few days anæmic cardiac murmurs can often be heard. Under favorable circumstances these symptoms of anæmia disappear in the course of a few weeks.

The other symptoms of ulcer, particularly the pain, are sometimes notably relieved, and may even disappear, after an abundant hemorrhage. They usually, however, return sooner or later. After a variable interval one attack of hæmatemesis is likely to be followed by others. There is much diversity in different cases as regards the frequency of these attacks and the character of the symptoms in the intervals. In a few cases recovery follows a single attack of gastric hemorrhage; in other cases the hemorrhage recurs frequently after intervals of only a few days, weeks, or months; in still other cases hemorrhage recurs only after long intervals, perhaps of years, although other symptoms of ulcer continue. Sometimes the disappearance of symptoms indicates only an apparent cure, and later the patient dies suddenly while in apparent health by a profuse gastric hemorrhage. In the rare cases of this last variety Cruveilhier has found sometimes that the ulcer has cicatrized except just over the eroded blood-vessel.

The sources of the hemorrhage in gastric ulcer will be described in connection with the morbid anatomy.

The symptoms of gastric indigestion are commonly, although not constantly, present in gastric ulcer. They may constitute the sole symptoms, in which case the diagnosis of the lesion is impossible. The most important local symptoms of gastric dyspepsia are diminution, less frequently perversion or increase, of the appetite; increased thirst; during digestion, and sometimes independent of digestion, a feeling of discomfort merely or of painful oppression, or even of sharp pain, in the epigastrium; nausea; vomiting of undigested food, of mucus, and of bile; regurgitation of thin fluids; often acid, sometimes neutral or alkaline, flatulence, with belching of gas, and constipation. In many cases of gastric ulcer the appetite is not disturbed, but the patient refrains from eating on account of the pain caused by taking food. Among the so-called sympathetic symptoms of dyspepsia are headache, dizziness, depression of spirits, oppression in the chest, and irregularity of the heart's action. Dyspepsia contributes its share to the production of the anæmia and of the loss of flesh and strength which are present in some degree in most cases of chronic gastric ulcer.

In many cases of acute perforating ulcer, as well as in some cases of chronic ulcer, the symptoms are either absent or they are but slightly marked. It has been demonstrated that in many cases of gastric ulcer the resorptive power of the mucous membrane of the stomach is unimpaired.⁴⁴

⁴⁴ This is shown by the experiments of Pentzoldt and Faber, who determined the length of time which elapsed between swallowing gelatin capsules containing iodide of potassium and the appearance of the iodide in the saliva (Berl. klin. Wochenschr., No. 21, 1882). Quetsch observed rapid absorption from the stomach in two cases of gastric ulcer (ibid., 1884, No. 23). It is believed that also the duration of the digestive process in the stomach is often within normal limits in cases of gastric ulcer, although exact experiments upon this point, as they require the use of the stomach-pump, have not been made in this disease (Leube).

The most common cause of dyspepsia in gastric ulcer is the chronic catarrhal gastritis which usually accompanies this disease. It is probable that the movements of the stomach may be seriously interfered with by destruction of the muscular coat of the stomach when the ulcer is of considerable size and is seated in the pyloric region. Adhesions of the stomach to surrounding parts may likewise impair the normal movements of the stomach. It is possible that ulcers, especially those which are very painful, may cause reflex disturbance of the peristaltic movements of the stomach and alterations in the quality or the quantity of the gastric juice. The serious digestive disturbances which are caused by distortions and dilatation of the stomach resulting from cicatricial contraction of gastric ulcer are not considered in this article.

Although Niemeyer emphasized the frequency in gastric ulcer of a strikingly red tongue with smooth or furrowed surface, it does not appear that any especial importance is to be attached to this or to any other condition of the tongue as a symptom of the disease.

Increased flow of saliva is a rare symptom, which, when it occurs, is usually associated with dyspepsia.

Constipation is the rule in gastric ulcer. The most important of the various circumstances which combine to produce this condition is the small amount of solid food taken and retained by the patient. The restraint caused by gastric ulcer and gastric catarrh in the normal movements of the stomach may diminish by reflex action the peristalsis of the intestines (Traube and Radziejewski). The passage of large quantities of blood along the intestinal canal is often associated with colicky pains and diarrhoea.

Amenorrhoea is a symptom which was formerly thought to be characteristic of gastric ulcer, although there was much discussion as to whether it was the cause or the result of the ulcer. Amenorrhoea is indeed common in the gastric ulcer of young women, but there is nothing strange in this when one considers the frequency of amenorrhoea in general, and its causation by various debilitating and depressing influences such as are to be found in gastric ulcer. Notwithstanding a few striking cases which have been recorded, it has not been demonstrated that hemorrhages vicarious of menstruation take place from gastric ulcer.

Gastric ulcer is not a febrile disease. Temporary elevation of temperature may follow profuse gastrorrhagia and may attend various complications, of which the most important are gastritis and peritonitis. It has been recently claimed by Peter that the surface-temperature of the epigastrium is elevated in gastric ulcer, but the observations upon this point are as yet too few for any positive conclusions.⁴⁵

⁴⁵ According to Peter, the normal surface-temperature of the epigastrium is from 95½° to 96° F. (35.3° to 35.5° C.), while in gastric ulcer the temperature may equal or even exceed by one or two degrees the axillary temperature. It is said to register the highest during attacks of pain and of vomiting and after hemorrhages (Gaz. des Hôpitaux, June 23 and 30, 1883). See also Beaurieux (Essai sur la Pseudo-gastralgie, etc., Thèse, Paris, 1879).

The general health of the patient remains sometimes surprisingly good, even in cases of gastric ulcer with symptoms sufficiently marked to establish the diagnosis. But in most cases of chronic gastric ulcer the general nutrition sooner or later becomes impaired. This cannot well be otherwise when dyspepsia, vomiting, paroxysms of severe pain, and hemorrhage are present, separately or in combination, for any great length of time. In proportion to the severity and the continuance of these symptoms the patient becomes pale, weak, and emaciated. The face, thin, anxious, of a grayish-white color, and marked with sharp lines of suffering, presents the appearance which the older writers called facies abdominalis, to which even so recent an author as Brinton attaches exaggerated diagnostic importance. A little cachectic dropsy may appear about the ankles. While it is true that the general nutrition is less rapidly, less continuously, and, as a rule, less deeply, impaired in gastric ulcer than in gastric cancer, nevertheless sometimes a cachexia develops in the former which is not to be distinguished from that of cancer. Litten⁴⁶ relates a case of gastric ulcer which simulated for a time pernicious anæmia. In this case the profound anæmia could not be explained by vomiting, hemorrhage, or other symptoms of ulcer.

⁴⁶ Berliner klin. Wochenschrift, Dec. 6, 1880.

Beyond determining the existence of a fixed point of epigastric tenderness, physical examination of the region of the stomach is usually only of negative value in the diagnosis of gastric ulcer. In some cases of ulcer of the stomach epigastric pulsation is very marked, and sometimes most marked during gastralgic attacks. In these cases there may be dilatation of the aorta from paralysis of vaso-motor nerves analogous to the dilatation of the carotid and temporal arteries in certain forms of migraine (Rosenbach). When the diagnosis lies between gastric ulcer and gastric cancer, the presence of epigastric tumor is justly considered to weigh against ulcer; but it is important to know that tumor may be associated with ulcer. Thickening of the tissues around old ulcers and the presence of adhesions may give rise to a tumor. A thickened portion of omentum which had become adherent over an old gastric ulcer produced a tumor which led to a mistake in the diagnosis.⁴⁷ Rosenbach⁴⁸ calls attention to the occasional production of false tumors by spasm of the muscular coat of the stomach around a gastric ulcer. These tumors disappear spontaneously or yield to the artificial distension of the stomach by Seidlitz powders—a procedure which one would not venture to adopt if he suspected gastric ulcer. Fenwick thinks that in some cases of gastric ulcer fixation of the stomach by adhesions can be made out by physical exploration.

The gravest symptom which can occur in gastric ulcer is the perforation of the ulcer into the general peritoneal cavity.

Only rough estimates can be made of the frequency of this symptom. These estimates vary from 2 to 25 per cent. From the data which I have collected I infer that perforation into the general peritoneal cavity occurs in about 6½ per cent. of all cases of gastric ulcer.⁴⁹

⁴⁹ Miquel (Schmidt's Jahrb., Bd. 125, p. 65, 1864) reckons the frequency of perforation at 2 per cent. Brinton's estimate of 13½ per cent. is the one generally accepted. He found 69 cases of perforation in 257 open ulcers collected from various sources. He doubles the number of open ulcers, as he considers cicatrized ulcers twice as frequent as the open. The statistics of some of the authors to whom he refers should not be used in this computation, either because they do not give accurately the number of cases of perforation, or because they include under perforation all cases of ulcer which have penetrated all of the coats of the stomach, whereas of course only perforation into the general peritoneal cavity should be here included. Valuable and laborious as are Brinton's researches, his statistics upon this point, as upon many others, are inaccurate.

In 249 fatal cases of open ulcer taken from the statistics of Jaksch, Dittrich, Willigk, Wrany (Prager Vierteljahr., vols. xcv. and xcix.), Eppinger, Starcke, Chambers, Moore, and Lebert (loc. cit.), I find 50 cases of perforation into the peritoneal cavity. This makes the percentage of perforations 6½ if the open ulcers be multiplied by 3, the number of cicatrized ulcers being taken as three times that of open ulcers (p. [482]). This method of computation, which is adopted by Brinton, is defective on account of the uncertainty as to the proper proportion between cicatrized and open ulcers.

Lebert observed 9 cases of perforation with fatal peritonitis in his 252 cases studied clinically. He places the frequency of perforation with peritonitis at 3 to 5 per cent., which corresponds to Engel's estimate of 5½ per cent. (Prager Vierteljahrschrift, 1853, ii.).

As regards sex, perforation occurs two to three times oftener in the female than in the male. This increased liability is referable mainly to the preponderance of the acute perforating ulcer in young women.⁵⁰

⁵⁰ The liability to perforation in females seems to be not only absolutely, but also relatively, to the number of ulcers greater than in males, although, on the contrary, Brinton holds that the excess of perforations in females is not greater than that of ulcers. Berthold found perforation in 3.1 per cent. of the cases of gastric ulcer in males, and in 9.7 per cent. of the cases in females (op. cit., p. 28).

In the female the liability to perforation of gastric ulcer is greatest between fourteen and thirty years of age. In the male there seems to be no greater liability to perforation at one age than at another.⁵¹

⁵¹ Of 139 cases of perforated ulcer in females, Brinton found that four-fifths occurred before the age of thirty-five. He calculates the average age at which perforation occurs in the female as twenty-seven, and in the male as forty-two. He thinks that the average liability to perforation in both sexes decreases as life advances, although he holds that the liability to ulcer itself constantly increases with age.

As will be explained in considering the morbid anatomy, ulcers of the anterior wall of the stomach perforate more frequently than those in other situations.

As regards the symptoms which may have preceded perforation three groups of cases can be distinguished:

In the first there has been no complaint of gastric disturbance. In the midst of apparent health perforation may occur and cause death within a few hours. This is the ulcère foudroyante of French writers. It is met with more commonly in chlorotic young women than in any other class.

In the second group of cases, which are more frequent, gastric symptoms have been present for a longer or shorter time, but have been so ambiguous that the diagnosis of gastric ulcer is not clear until perforation occurs. Then, unfortunately, the diagnosis is of little more than retrospective interest.

In the third group of cases perforation takes place in the course of gastric ulcer, the existence of which has been made evident by characteristic symptoms, such as localized pain and profuse hemorrhage.

The immediate cause of perforation of gastric ulcer is often some agency which produces mechanical tension of the stomach, such as distension of the organ with food or with gas, vomiting, straining at stool, coughing, sneezing, pressure on the epigastrium, violent exertion, and jolting of the body.

With the escape of the solid, the fluid, and the gaseous contents of the stomach into the peritoneal cavity at the moment of perforation, an agonizing pain is felt, beginning in the epigastrium and extending rapidly over the abdomen, which becomes very sensitive to pressure. The pain sometimes radiates to the shoulders. Symptoms of collapse often appear immediately or they may develop gradually. The pulse becomes small, rapid, and feeble. The face is pale, anxious, and drawn (facies hippocratica). The surface of the body, particularly of the extremities, is cold and covered with clammy sweat. The internal temperature may be subnormal, normal, or elevated; after the development of peritonitis it is usually, but not always, elevated. Consciousness is usually retained to the last, although the patient is apathetic. Vomiting is sometimes absent—a circumstance which may be of value in diagnosis, and which Traube attributes to the readiness with which the contents of the stomach can be discharged through the abnormal opening into the peritoneal cavity. There is usually constipation. The respirations become more and more frequent and costal in type. Thirst is often urgent. Suppression of urine is not an uncommon symptom, although there may be frequent and painful attempts at micturition. Albumen and casts may appear temporarily in the urine. Retraction of one testicle, like that in renal colic, has been observed (Blomfield). The patient usually lies on his back with the knees drawn up. The abdomen is often at first hard and retracted from spasmodic contraction of the abdominal muscles, but later it usually becomes tympanitic, sometimes to an extreme degree. The presence of tympanitic resonance replacing hepatic dulness in front is usually considered the most important physical sign of gas free in the peritoneal cavity, but this sign is equivocal. On the one hand, the presence of adhesions over the anterior surface of the liver may prevent the gas from getting between the liver and the diaphragm;⁵² and on the other hand, in cases of meteorism coils of intestine may make their way between the liver and the diaphragm, or the liver may be pushed upward and backward, so that its anterior surface becomes superior and the hepatic dulness in front disappears. Physical examination may reveal in the dependent parts of the peritoneal cavity an accumulation of fluid partly escaped from the stomach and partly an inflammatory exudate.⁵³ For humane reasons one should not submit the patient to the pain of movement in order to elicit a succussion sound or to determine change in the position of the fluid upon changing the position of the patient.⁵⁴ There is sometimes relief from pain for some hours before death.

⁵² Even without these adhesions liver dulness may persist after perforation of the stomach, as in a case of Nothnägel's in which for twenty-four hours after a large perforation from gastric ulcer the abdomen was retracted and hepatic dulness was well marked (Garmise, Ulcus Ventriculi cum peritonitide perforativa, Inaug. Diss., Jena, 1879).

⁵³ In a case of peritonitis resulting from perforation of a latent ulcer of the duodenum, Concato found in the acid fluid withdrawn by aspiration from the peritoneal cavity Sarcina ventriculi (Giorn. internaz. delle Scienze Med., 1879, No. 9).

⁵⁴ Other symptoms which have been thought to be diagnostic of pneumo-peritoneum in distinction from meteorism, but the value of which is doubtful, are these: In pneumo-peritoneum the respiratory murmur can be heard by auscultation over the entire abdomen, while in meteorism it does not extend beyond the region of the stomach (Cantani); in the former amphoric sounds synchronous with respiration can sometimes be heard over the abdomen (Larghi); borborygmi are heard, if at all, distantly and feebly; the percussion note of gas free over the liver is different from that of tympanitic intestine (Traube); the percussion note is of the same character over the whole anterior wall of the abdomen; the epigastric region is more elastic to the feel than in tympanites; the distension of the abdomen is more uniform than in tympanites; and coils of distended intestine, sometimes showing peristaltic movement, cannot be seen or felt as in some cases of meteorism (Howitz).

There are exceptional cases of perforation in which some of the most important of the enumerated symptoms, such as pain, tenderness of the abdomen on pressure, tympanites, and the symptoms of collapse, are absent.

Death sometimes occurs from shock within six or eight hours after perforation. More frequently life is prolonged from eighteen to thirty-six hours, it may be even for three or four days, and, very rarely, even longer.⁵⁵ When life is prolonged more than twelve hours an acute diffuse peritonitis is usually but not always developed.

⁵⁵ In the Descriptive Catalogue of the Warren Anatomical Museum, by Dr. J. B. S. Jackson, p. 448, Boston, 1870, is described a case of gastric ulcer in which, so far as can be judged by the symptoms and the post-mortem appearances, the patient lived nineteen days after perforation.

The contents of the stomach, instead of being diffused throughout the peritoneal cavity, may be confined by a rapidly-developed circumscribed peritonitis to a space near the stomach, or perforation may occur into a space previously shut off from the general peritoneal sac by adhesions. In this way circumscribed peritoneal abscesses form in the neighborhood of the stomach. Diffuse peritonitis may be caused either by an extension of the inflammation or by the rupture of these abscesses into the general peritoneal cavity. The cases of circumscribed peritonitis following perforation of gastric ulcer, with escape of the contents of the stomach, although more protracted than those in which the whole peritoneal surface is at once involved, generally terminate fatally sooner or later. The symptoms are often very obscure.

The most interesting of these peritoneal abscesses is the variety to which Leyden has given the name of pyo-pneumothorax subphrenicus (false pneumothorax of Cossy), the diagnostic features of which first were recognized by G. W. Barlow and Wilks in 1845.⁵⁶ Here there is a cavity, circumscribed by adhesions, just beneath the diaphragm, containing pus and gas and communicating with either the stomach or the intestine. By the encroachment of this cavity upon the thoracic space the symptoms and signs of pyo-pneumothorax are simulated. Barlow and Leyden have diagnosed during life this affection when resulting from perforated gastric ulcer. The points in diagnosis from genuine pyo-pneumothorax are the presence of respiratory murmur from the clavicle to the third rib, the extension of the respiratory murmur downward by deep inspiration, history of preceding gastric disturbance with circumscribed peritonitis, absence of preceding pulmonary symptoms, rapid variations in the limits of dulness with changes in the position of the body, absence or only slight evidence of increased intrapleural pressure (such as bulging of the thorax as a whole, and of the intercostal spaces), displacement of the heart, displacement of the liver downward, and, if necessary, the determination by means of a manometer that the pressure in the abscess cavity rises during inspiration and falls during expiration, the reverse being true in genuine pneumothorax.⁵⁷

⁵⁷ Schreiber has shown that this last diagnostic point, which was given by Leyden, is not without exceptions, for the pressure in the peritoneal cavity may sink during inspiration and rise during expiration (as in the pleural cavity), especially when the diaphragm takes little or no part in respiration ("Ueber Pleural- und Peritonealdruck," Deutsches Arch. f. klin. Med., July 31, 1883).

Through the medium of subphrenic abscess, or directly through adhesions between the stomach and the diaphragm, gastric ulcer may perforate into one of the pleural cavities (generally the left) and cause empyema or pneumo-pyothorax. Adhesions may form between the diaphragm and the pulmonary pleura, so that the ulcer perforates directly into the lung; in which case pulmonary gangrene or pulmonary abscess is usually developed. The diagnosis of the perforation into the lung has been made by recognizing a sour odor and sour reaction of the expectoration, and by finding in the sputum particles of food derived from the stomach. Sudden death from suffocation has followed perforation of the stomach into the lung.⁵⁸

⁵⁸ Tillmanns (loc. cit.) has collected 12 cases of communication between the stomach and the thoracic cavity from perforation of gastric ulcer; all proved fatal. In Sturges's case of recovery from pneumothorax supposed to be produced by perforation of a gastric ulcer the diagnosis of the cause of the pneumothorax was very doubtful (The Lancet, Feb. 7, 1874).

Perforation of gastric ulcer into the transverse colon has been followed by the vomiting of formed feces and by the passage of undigested food by the bowel (Abercrombie). Enemata may be vomited, so that, as suggested by Murchison, the introduction of colored enemata may aid in the diagnosis.

Gastro-cutaneous fistulæ are among the rare results of perforation of gastric ulcer. In these cases food, sometimes only in liquid form, escapes through the fistula.

The opening of gastric ulcer into the pericardium is one of the rare causes of pneumo-pericardium.

Other varieties of perforation which are of pathological rather than of clinical interest will be mentioned under the morbid anatomy of gastric ulcer.

COURSE.—Few diseases are more variable in their course and duration than is simple gastric ulcer. It is customary to distinguish between acute and chronic forms of gastric ulcer, but this is a distinction which cannot be sharply drawn. Those cases are called acute in which, with absence or short duration of antecedent gastric symptoms, perforation or gastrorrhagia suddenly causes death. But in some of these cases the thickened and indurated margins of the ulcer found at the autopsy show that the disease has been of much longer duration than the clinical history would indicate. Still, there is reason to believe that within the course of a few days ulcers may form and perforate all of the coats of the stomach.

In the great majority of cases of gastric ulcer the tendency is to assume a chronic course, so that the often-used term chronic gastric ulcer is generally applicable.

The great diversity of the symptoms in different cases makes it impossible to give a generally applicable description of the course of gastric ulcer. It is, however, useful to designate the main clinical forms of the disease. Thus we may distinguish—

1. Latent ulcers, with entire absence of symptoms, and revealed as open ulcers or as cicatrices at the autopsy.

2. Acute perforating ulcers. With or without a period of brief gastric disturbance perforation occurs and causes speedy death.

3. Acute hemorrhagic form of gastric ulcer. After a latent or a brief course of the ulcer profuse gastrorrhagia occurs, which may terminate fatally or may be followed by the symptoms of chronic ulcer.

4. Gastralgic-dyspeptic form. In this, which is the most common form of gastric ulcer gastralgia, dyspepsia and vomiting are the symptoms. Sometimes one of the symptoms predominates greatly over the others, so that Lebert distinguishes separately a gastralgic, a dyspeptic, and a vomitive variety. Gastralgia is the most frequent symptom.

5. Chronic hemorrhagic form. Gastrorrhagia is a marked symptom, and occurs usually in combination with the symptoms just mentioned.

6. Cachectic form. This usually corresponds only to the final stage of one of the preceding forms, but the cachexia may develop so rapidly and become so marked that the course of the disease closely resembles that of gastric cancer.

7. Recurrent form. In this the symptoms of gastric ulcer disappear, and then follow intervals, often of considerable duration, in which there is apparent cure, but the symptoms return, especially after some indiscretion in the mode of living. This intermittent course may continue for many years. In these cases it is probable either that fresh ulcers form or that the cicatrix of an old ulcer becomes ulcerated.

8. Stenotic form. By the formation of cicatricial tissue in and around the ulcer the pyloric orifice becomes obstructed and the symptoms of dilatation of the stomach develop.

DURATION.—The average duration of gastric ulcer may be said to be from three to five years, but this estimate is not of great value, on account of the absence of any regularity in the course and duration of the disease. In cases of very protracted duration, such as forty years in a case of Habershon's and thirty-five in one of Brinton's, it is uncertain whether the symptoms are referable to the persistence of one ulcer or to the formation of new ulcers, or to sequels resulting from cicatrization.

In 110 cases (44 fatal) analyzed by Lebert⁵⁹ the course was latent until the occurrence of perforation or of profuse hemorrhage in 15 per cent., the duration was less than one year in 18 per cent., from one to six years in 46½ per cent., from six to twenty years in 18 per cent., from twenty to thirty-five years in 2½ per cent.

⁵⁹ Op. cit., p. 235.

TERMINATIONS.—In the majority of cases gastric ulcer terminates in recovery. The recovery is often complete. Various gastric disturbances may, however, follow the cicatrization of gastric ulcer, especially if the ulcer was large and of long duration. These sequential disturbances are due to the contraction of the cicatrix, to adhesions between the stomach and surrounding parts, to deformity of the stomach, and especially to dilatation of the stomach by cicatricial stenosis of the pylorus. Hence, gastralgia, dyspepsia, and vomiting may continue after the ulcer has healed, so that anatomical cure of the ulcer is not always recovery in the clinical sense. Relapses may occur after recovery, as those who have once had gastric ulcer are more prone to the disease than are others. Not infrequently the patient recovers so far as to be able to attend to the active duties of life, but to avoid renewed attacks he is always obliged to be very careful as regards his mode of living.

How often gastric ulcer ends in death it is impossible to say. It is certain that Brinton under-estimates the number of recoveries when he computes that only one-half of the ulcers cicatrize. Lebert reckons the mortality from gastric ulcer as 10 per cent., which appears to be too low an estimate. Perhaps 15 per cent. would be a more correct estimate of the mortality.

The causes of death are perforation, hemorrhage, exhaustion, and complicating diseases.

About 6½ per cent. of the cases of gastric ulcer terminate fatally by perforation into the peritoneal cavity. Although this estimate can be considered only approximative, there is little doubt but that the much larger percentages given by most writers are excessive, and are referable to the undue frequency with which cases of perforation of gastric ulcer have been published. Such cases naturally make a strong impression upon the observer, and are more likely to be published than those which terminate in other ways.

Death from hemorrhage occurs probably in from 3 to 5 per cent. of the cases of gastric ulcer.⁶⁰ In many more cases hemorrhage is an indirect cause of death by inducing anæmia. Unlike perforation, fatal hemorrhage from gastric ulcer is more common in males than in females—more common after than before forty years of age. The average age at which fatal hemorrhage occurs is given by Brinton as forty-three and a half years both for males and females.

⁶⁰ In 270 fatal cases of open ulcer from the statistics of Jaksch, Dittrich, Eppinger, Starcke, Chambers, Habershon, Moore, and Lebert, I find 27 deaths by hemorrhage. Reckoning three cicatrices to one ulcer, this would give a percentage of 3¹/3.

In a considerable proportion of the fatal cases exhaustion is the cause of death. According to Lebert, death from exhaustion occurs in about 4 per cent. of the cases of gastric ulcer. The causes of exhaustion are the pain, hemorrhage, dyspepsia, and vomiting which constitute the leading symptoms of the disease.

Finally, death may be due to some of the complications or sequels of gastric ulcer.

COMPLICATIONS.—Some of the complications of gastric ulcer are directly referable to the ulcer, others are only remotely related to it, and others are merely accidental.

Pylephlebitis is among the most important of the complications directly referable to the ulcer. This pylephlebitis is usually of the infectious variety, and leads to abscesses in the liver, sometimes to abscesses in the spleen and other organs.

As has already been mentioned, chronic catarrhal gastritis stands in close relationship to gastric ulcer. Chronic peritonitis is a rare complication of gastric ulcer (Moore, Vierordt). Chronic interstitial gastritis, with contraction of the stomach and thickening of its walls, was associated with ulcer in a case under my observation. In a case of ulcer under the care of Owen Rees⁶¹ this condition of the stomach was associated with chronic deforming peritonitis (thickening, induration, and contraction of the peritoneum) and ascites, so that the symptoms during life and the gross appearances after death resembled cancerous diseases of the peritoneum. Simple ulcer and cancer may occur together in the same stomach, or cancer may develop in an ulcer or its cicatrix. Glässer reports a case of phlegmonous gastritis with gastric ulcer.⁶² Extension of inflammation to the pleura without perforation of the diaphragm sometimes occurs. Fatty degeneration of the heart may be the result of profound anæmia induced by gastric ulcer.⁶³ Embolic pneumonia and broncho-pneumonia are occasional complications. A moderate degree of cachectic dropsy is not very infrequent in the late stages of gastric ulcer.

⁶³ Shattuck, Boston Med. and Surg. Journ., June, 1880, vol. ciii.

Other complications, such as pulmonary tuberculosis, valvular disease of the heart, general atheroma of the arteries, cirrhosis of the liver, syphilis, chronic Bright's disease, waxy degenerations, and malaria, have been considered under the Etiology, and some of them will be referred to again in connection with the Pathology, of gastric ulcer. In most instances when ulcer is associated with these diseases the ulcer is secondary.

SEQUELÆ.—The most important sequelæ of gastric ulcer are changes in the form of the stomach in consequence of adhesions and in consequence of the formation and contraction of cicatrices. These lesions are most conveniently described under the Morbid Anatomy. The symptoms of the most important of these sequels—namely, stenosis of the pylorus with dilatation of the stomach—will be described in another article.

MORBID ANATOMY.—As regards number, simple ulcer of the stomach is usually single, but occasionally two or more ulcers are present. It is not uncommon to meet in the same stomach open ulcers and the scars of healed ulcers. According to Brinton, multiple ulcers are found in about one-fifth of the cases. In one case O'Rorke found six ulcers on the anterior wall of the stomach.⁶⁴ Berthold mentions a case in which thirty-four ulcers were found in the same stomach.⁶⁵

⁶⁴ Trans. of the New York Path. Soc., vol. i. p. 241. Wollmann mentions the occurrence of over eight simple ulcers in the same stomach (Virchow und Hirsch's Jahresb., 1868, Bd. ii. p. 126).

⁶⁵ Op. cit., p. 21. It is expressly stated that these were not hemorrhagic erosions, but deep corrosive ulcers.

The usual position of simple gastric ulcer is the posterior wall of the pyloric portion of the stomach on or near the lesser curvature. Ulcers of the anterior wall are rare, but they carry a special danger from their liability to perforate without protective adhesions. The least frequent seats of ulcer are the greater curvature and the fundus.

The table on page 504 gives the situation of 793 ulcers recorded in hospital statistics:⁶⁶

Lesser curvature	288	(36.3 per cent.)
Posterior wall	235	(29.6 per cent.)
Pylorus	95	(12 per cent.)
Anterior wall	69	(8.7 per cent.)
Cardia	50	(6.3 per cent.)
Fundus	29	(3.7 per cent.)
Greater curvature	27	(3.4 per cent.)

From this table it is apparent that ulcers occupy the lesser curvature, the posterior wall, and the pyloric region three and a half times more frequently than they do the remaining larger segment of the stomach.

⁶⁶ These statistics are collected from the previously-cited works of Rokitansky, Jaksch, Wrany, Eppinger, Chambers, Habershon, Steiner, Wollmann, Berthold, Starcke, Lebert, and Moore. They represent 566 cases. So far as noted, most of the ulcers on the posterior wall were nearer to the lesser curvature than to the greater; those on the lesser curvature extended more frequently to the posterior than to the anterior wall. Although not apparent from the table, most of the ulcers of the lesser curvature and of the posterior wall were in the pyloric region. So far as possible, cicatrices were excluded. Pylorus and cardia in the table indicate on or near those parts.

Occasionally two ulcers are seated directly opposite to each other, the one on the anterior, the other on the posterior, wall of the stomach. The most plausible explanation of this is that the ulcers are caused by a simultaneous affection of corresponding branches which are given off symmetrically from the same arterial trunk as it runs along one of the curvatures of the stomach (Virchow).⁶⁷

⁶⁷ A. Beer, "Aus dem path. Anatom. Curse et. Prof. R. Virchow, etc.," Wiener med. Wochenschr., Nos. 26, 27, 1857.

The ordinary size of the ulcer varies from a half inch to two inches in diameter. The ulcer may be very minute, as in two cases reported by Murchison, in each of which a pore-like hole was found leading into a perforated artery from which fatal hemorrhage had occurred.⁶⁸ On the other hand, the ulcer may attain an enormous size, extending sometimes from the cardiac to the pyloric orifice and measuring five or six inches in diameter.⁶⁹

⁶⁸ Murchison, Trans. of the Path. Soc., vol. xxi. p. 162, London, 1870.

⁶⁹ In one of Cruveilhier's cases the ulcer was 6½ inches long and 3¹/3 inches wide. Law describes an ulcer measuring 6 inches by 3 inches (Dublin Hosp. Gaz., ii. p. 51).

The ulcer is usually round or oval in shape. The outline of the ulcer may become irregular by unequal extension in the periphery, or by the coalescence of two or more ulcers, or by partial cicatrization. Simple ulcers, especially when seated near the lesser curvature, have a tendency to extend transversely to the long axis of the stomach, thus following the course of the blood-vessels. By this mode of extension, or more frequently by the coalescence of several ulcers, are formed girdle ulcers, which more or less completely surround the circumference of the stomach, oftener in the pyloric region than elsewhere.

As the ulcer extends in depth it often destroys each successive layer of the stomach in less extent than the preceding one, so that the form of the ulcer is conical or funnel-shaped, with a terrace-like appearance in its sloping edges. The apex of the truncated cone, which is directed toward the peritoneum, is often not directly opposite to the centre of the base or superior surface which occupies the mucous membrane, so that one side of the cone may be vertical and the other sloping. In the half of the stomach nearer the lesser curvature the cone slopes upward, and in the lower half of the stomach it slopes downward. The usual explanation of its conical shape is that the ulcer exactly corresponds to the territory supplied by an artery with its branches. Virchow finds an explanation for the oblique direction of the funnel in the arrangement of the arteries of the stomach. These, coming from different sources, run along the curvatures of the stomach, and there give off symmetrically branches which run obliquely toward the mucous membrane, so that one of these branches with its distributive twigs (arterial tree) would supply a part shaped like an oblique funnel. One of the chief supports of the theory which refers the origin of simple gastric ulcer to an arrest of the circulation is this correspondence in shape of the ulcer to the area of distribution of the branches of the arteries supplying the stomach.

All ulcers do not present the conical form and terraced edges which have been described. These appearances are far from constant in fresh ulcers, and they are usually absent in those of long duration.

The most characteristic anatomical feature of simple ulcer of the stomach is the appearance of the edges and of the floor of the ulcer. The edges of recently-formed ulcers (acute ulcers) are clean-cut, smooth, and not swollen. To use Rokitansky's well-known comparison, the hole in the mucous coat looks as if it had been punched out by an instrument. The floor of the ulcer may be smooth and firm or soft and pulpy. The floor and edges of fresh ulcers are often infiltrated with blood, but they may be of a pale-grayish color. Usually no granulations and no pus are to be seen on the surface of the ulcer.⁷⁰ In ulcers of longer duration the margins become thickened, indurated, and abrupt; the floor acquires a dense fibrous structure.

⁷⁰ In rare instances granulations may be present, as in a case of W. Müller's, in which their presence rendered difficult the diagnosis of simple ulcer from carcinoma (Jenaische Zeitschrift, v., 1870). The microscope may also be required to distinguish the irregularly thickened margins of old ulcers from scirrhous cancer.

The floor of the ulcer may be the submucous, the muscular, or the serous coat, or, if the whole thickness of the stomach be perforated, it may be some adjacent organ to which the stomach has become adherent, this organ being usually the pancreas or the left lobe of the liver or neighboring lymphatic glands.

The microscopic examination of recently-formed ulcers shows that the tissue immediately surrounding the ulcer is composed of granular material, disintegrated red blood-corpuscles, pale and swollen fragments of connective-tissue fibres, and cells unaffected by nuclear-staining dyes. The red blood-corpuscles are sometimes broken into fragments of various sizes in about the same way as by the action of heat. The gastric tubules are separated from each other and compressed by infiltrated blood, and contain cells which do not stain. Around this margin of molecular disintegration, which has evidently been produced by the action of the gastric juice, there is often, although not constantly, a zone of infiltration with small round cells, probably emigrated white blood-corpuscles. These cells are most abundant near the muscularis mucosæ and in the submucosa. Extravasated red blood-corpuscles extend a variable distance around the ulcer, farthest as a rule in the submucous coat. Many of the blood-vessels in the immediate neighborhood of the ulcer appear normal; others, particularly the arterioles and the capillaries, may be filled with hyaline thrombi. Clumps of hyaline material may also be seen in the meshes of the tissue around the ulcer. Fine fatty granules may be seen in the tissue near the ulcer. The interstices of the loose submucous tissue and the lymphatic vessels are often filled with fibrillated fibrin and scattered blood-corpuscles for a considerable distance around the ulcer.

In the margins of old gastric ulcers there is also a zone of molecular necrosis. The induration and the thickening of the edges of these ulcers are caused by a new growth of fibrillated connective tissue, which blends together all of the coats invaded by the ulcer. This new tissue is usually rich in lymphoid cells, which are often most abundant in the lymphatic channels. In the fibrous edges and base of old ulcers are arteries which are the seat of an obliterating endarteritis, and which may be completely obliterated by this process. An interstitial neuritis may affect the nerve-trunks involved in the fibrous growth. Blood-pigment may be present as an evidence of an old hemorrhagic infiltration.⁷¹

⁷¹ The histological changes here described are based upon the examination of typical specimens both of recent and of old gastric ulcers which have come under my observation.

Cicatrization is accomplished by the development of fibrous tissue in the floor and borders of the ulcer. By the contraction of this new-formed tissue the edges of the mucous membrane are united to the floor of the ulcer, and may be drawn together so as to close completely the defect in the mucous membrane. The result is a white stellate cicatrix, which is usually somewhat depressed and surrounded by puckered mucous membrane. It is probable that small, superficial ulcers may be closed so that the scar cannot be detected. The mucous membrane which has been drawn over the cicatrix is intimately blended with the fibrous substratum, and is usually itself invaded by fibrous tissue which compresses and distorts the gastric tubules. Hauser⁷² has shown that the tubular glands grow down into the cicatricial tissue, where they may branch in all directions. These new-formed tubules are lined by clear cylindrical or cutical epithelial cells, and may undergo cystic dilatation. Very irregular cicatrices may result from the healing of large and irregular ulcers. When the ulcer is large and deep and the stomach is adherent to surrounding parts, the edges of the mucous membrane making the border of the ulcer cannot be united by the contraction of the fibrous tissue in the floor of the ulcer. The cicatrix of such ulcers consists of fibrous tissue uncovered by mucous membrane. The closure of the ulcer is incomplete. Such cicatrices are liable to be the seat of renewed ulceration.

⁷² Das chronische Magengeschwür, etc., Leipzig, 1883. In the rare instances of carcinoma developing in the borders or in the cicatrix of gastric ulcer, Hauser believes that the cancerous growth starts from these glandular growths, which in general have only the significance of Friedländer's atypical proliferation of epithelial cells.

The formation and contraction of the cicatrix may cause various deformities of the stomach. The character of these deformities depends upon the situation, the size, and the depth of the ulcer which is cicatrized. Among the most important of these distortions are stenosis of the pyloric orifice, followed by dilatation of the stomach, more rarely stenosis of the cardiac orifice, with contraction of the stomach, approximation of the cardiac and of the pyloric orifices by the healing of ulcers on the lesser curvature, and an hour-glass form of the stomach, produced by the cicatrization of girdle ulcers or of a series of ulcers extending around the stomach. These abnormalities in form of the stomach, particularly the constriction of the orifices, may be attended by more serious symptoms than the original ulcer.

As the ulcer extends in depth a circumscribed peritonitis, resulting in the formation of adhesions between the stomach and surrounding parts, is usually excited before the serous coat is perforated, so that the gravest of all possible accidents in the course of gastric ulcer—namely, perforation into the peritoneal sac—is permanently or temporarily averted. It has been estimated that adhesions form in about two-fifths of all cases of gastric ulcer (Jaksch). On account of the usual position of the ulcer on the lesser curvature or on the posterior wall of the stomach, the adhesions are most frequently with the pancreas (in about one-half of all cases of adhesion); next in frequency with the left lobe of the liver; rarely with other parts, such as the lymphatic glands, the diaphragm, the spleen, the kidney, the suprarenal capsule, the omentum, the colon, and other parts of the intestine, the gall-bladder, the sternum, and the anterior abdominal wall. Adhesions cannot readily form between the anterior surface of the stomach and the anterior abdominal wall, on account of the constant movement of these parts, so that ulcers of the anterior gastric wall are those most liable to perforate into the peritoneal cavity.

It is difficult to include in any description all of the various and complicated lesions which may result from perforation by gastric ulcer of all of the coats of the stomach. The consequences of perforation may be conveniently classified as follows:

1. Some solid organ, usually the pancreas, the liver, or the lymphatic glands, may close the hole in the stomach.

2. An intra-peritoneal sac shut in by adhesions may communicate through the ulcer with the cavity of the stomach.

3. A fistulous communication may form either between the stomach and the exterior (external gastric fistula) or between the stomach and some hollow viscus (internal gastric fistula).

4. The ulcer may perforate into the general peritoneal cavity.

These lesions may be variously combined with each other. It is to be noted that in the first three varieties protective adhesions are present, and that in the last these adhesions are either absent or ruptured.

When the pancreas, the liver, or the spleen form the floor of the ulcer, they may be protected from extension of the ulcerative process by a new growth of fibrous tissue extending from the floor of the ulcer a variable depth into these organs. Sometimes, however, the ulcerative process, aided doubtless by the corroding action of the gastric juice, eats out large excavations in these organs. These excavations communicate with the cavity of the stomach, and are usually filled with ichorous pus. The pancreas, unlike the spleen and the liver, possesses comparative immunity against this invasion by the ulcerative process.

The situation, the form, and the extent of circumscribed peritoneal abscesses resulting from perforation of gastric ulcer depend upon the parts with which the stomach has contracted adhesions. Should an ulcer on the posterior wall of the stomach perforate before the formation of adhesions, the perforation would of course be directly into the lesser peritoneal cavity. An interesting example of this rare occurrence has been communicated by Chiari.⁷³ In this case, the foramen of Winslow being closed by adhesions, the lesser peritoneal cavity which communicated with a gastric ulcer was filled with ichorous pus, and in this floated the pancreas, which had necrosed in mass and had separated as a sequestrum. That form of intra-peritoneal abscess known as subphrenic pneumo-pyothorax has been already described under Symptomatology. Peritoneal abscesses communicating with the stomach may open into various places, as into the general peritoneal cavity, into the pleural cavity, into the retro-peritoneal tissue, through the abdominal or thoracic walls, etc.

⁷³ Wiener med. Wochenschr., 1876, No. 13.

Gastro-cutaneous fistulæ are a rare result of the perforation of gastric ulcer.⁷⁴ The external opening is most frequently in the umbilical region, but it may be in the epigastric or in the left hypochondriac region or between the ribs. Fistulous communications resulting from the perforation of gastric ulcer have been formed between the stomach and one or more of the following hollow viscera or cavities: the colon, the duodenum and other parts of the small intestine, the gall-bladder, the common bile-duct, the pancreatic duct, the pleura, the lung, the left bronchus, the pericardium, and the left ventricle. Gastro-colic fistulæ, in contrast to gastro-cutaneous fistulæ, are more frequently produced by cancer than by ulcer of the stomach.⁷⁵ In rare instances the peritoneum over ulcers of the lesser curvature has contracted adhesions with the pyloric portion of the stomach or with the first part of the duodenum. To accomplish this it is necessary that a sharp bend in the lesser curvature should take place. By extension of the ulcerative process abnormal communication is established between the left and the right half of the stomach or between the stomach and the duodenum. In either case the right half of the stomach is often converted into a large blind diverticulum, the digested food passing through the abnormal opening.⁷⁶ Gastro-duodenal fistulæ are more frequently with the third than with the first part of the duodenum. In one of Starcke's cases the stomach communicated with the colon and through the medium of a subphrenic abscess with the left lung.⁷⁷

⁷⁴ Of the 25 cases of gastro-cutaneous fistula collected by Murchison, 18 were the result of disease. In 12 of these cases the probable cause was simple gastric ulcer (Med.-Chir. Trans., vol. xli. p. 11, London, 1858). Middeldorpf says that among the internal causes of the 47 cases of external gastric fistula which he tabulated, simple ulcer of the stomach played an important rôle (Wiener med. Wochenschr., 1860).

⁷⁵ Of 33 cases of gastro-colic fistula collected by Murchison, 21 were from gastric cancer and 9 or 10 probably from simple ulcer. On the other hand, gastro-cutaneous fistulæ are twice as frequently the result of simple ulcer as of cancer (Edinb. Med. Journ., vol. iii. 1857).

⁷⁶ Thierfelder has made the best study of the complicated relations existing in these cases (Deutsches Arch. f. klin. Med., Bd. iv. p. 33, 1868).

⁷⁷ Deutsche Klinik, 1870, No. 39. Habershon also reports a case in which a subphrenic abscess communicated with the lung, the stomach, and the colon, but he believes that the ulceration was primary in the colon (Guy's Hosp. Rep., Ser. 3, vol. i. p. 109).

Four cases of perforation of gastric ulcer into the pericardium,⁷⁸ with the production of pneumo-pericardium, have been reported, and two cases of perforation into the left ventricle.⁷⁹ Müller found lumbricoid worms in a pleural cavity which had been perforated by gastric ulcer.⁸⁰ Diaphragmatic hernia may result from perforation of the pleural cavity by gastric ulcer.⁸¹ In one instance the greater part of the small intestines passed through a hole in the transverse meso-colon which had been caused by a gastric ulcer.

Murchison mentions a specimen in the museum of King's College, London, of a simple gastric ulcer opening into the pericardium (Edinb. Med. Journ., vol. iii. p. 6). In a case reported by Graves a liver abscess burst into the stomach and into the pericardium (Clin. Lect., ii. p. 237, Dublin, 1848).

⁸⁰ Müller, Memorabilien, xvii., Oct., 1872.

⁸¹ Needon, Wiener med. Presse, 1869, No. 42. In a case of Günsburg's the hole in the diaphragm was as large as the hand, and the left pleural cavity contained the upper half of the stomach and the spleen (Arch. f. phys. Heilk., xi. 3, 1852).

The various fistulæ which have been mentioned may be either direct or through the medium of an abscess. While some of them are only pathological curiosities, others, particularly the communications of the stomach with the pleural cavity and with the lung, are sufficiently frequent to be of practical clinical interest.

As has already been explained, ulcers of the anterior wall are the ones most liable to perforate into the general peritoneal cavity,⁸² but on account of their comparative infrequency perforation occurs oftener in other situations, particularly in the lesser curvature and near the pylorus. Except on the anterior wall the perforation is often brought about by the rupture of adhesions which for a time had prevented this accident. In a considerable number of cases, particularly of ulcers on the anterior wall, the ulcer looks as if recently formed (acute perforating ulcer); in other cases its thickened and indurated margins indicate long duration. Chiari⁸³ describes a case in which rupture into the peritoneal cavity took place through the cicatrix of an old ulcer, probably in consequence of the distension of the stomach with gas. The hole in the peritoneum is usually circular, smaller than the inner surface of the ulcer, and has sharp, well-defined edges. Less frequently the edges are ragged. Post-mortem digestion may, however, so change the borders of the opening as to make it difficult or impossible to tell from their post-mortem appearances alone whether perforation has occurred before or after death. The peritoneal cavity after death from perforation is found to contain gas and substances from the stomach. Usually within a few hours after perforation septic peritonitis is excited, but in exceptional cases no inflammation of the peritoneum has occurred even when life has been prolonged twenty-four hours after perforation.

⁸² According to Brinton, "the proportion of perforations to ulcers is such that of every 100 ulcers in each of the following situations, the numbers which perforate are—on the posterior surface, about 2; the pyloric sac, 10; the middle of the organ, 13; the lesser curvature, 18; the anterior and posterior surface at once, 28; the cardiac extremity, 40; and the anterior surface, 85."

⁸³ Wiener med. Blätter, 1881, No. 3.

Emphysema of the subcutaneous, subperitoneal, and other loose areolar tissue of the body is a rare but remarkable result of the perforation of gastric ulcer. The emphysema is sometimes observed shortly before death, but it attains its maximum development after death, when it may spread rapidly over the greater part of the body. The gas consists in part of hydrogen, as it burns with a blue flame. It is generated, at least in great part, by fermentation of the contents of the stomach. The gas may enter the subserous tissue at the edges of the ulcer and thence spread, or, after perforation of the stomach, it may make its way from the peritoneal cavity into the loose subserous connective tissue through some place in the parietal peritoneum which has been macerated, perhaps by the digestive action of the gastric juice.⁸⁴

⁸⁴ Roger (Arch. gén. de Méd., 1862) and Demarquay (Essai de Pneumatologie médicale, Paris, 1866) deserve the credit of first calling general attention to the occurrence of subcutaneous emphysema after rupture of the digestive tract. The following writers have each reported a case of emphysema following the perforation of gastric ulcers: Cruveilhier, Anat. Path., t. i. livr. xx.; Bell, Edinb. Med. Journ., vol. vi. p. 783; Thierfelder, Deutsches Arch. f. klin. Med., iv., 1868, p. 33; Newman, The Lancet, 1868, vol. ii. p. 728; Poensgen, Das subcutane Emphysem nach continuitätstrennungen des Digestionstractus, etc., Inaug. Diss., Strassburg, 1879, p. 40; Korach, Deutsche med. Wochenschr., 1880 p. 275; Jürgensen, Deutsches Arch. f. klin. Med., Bd. 31, p. 441, 1882. Doubtful cases are reported by Lefèvre, W. Mayer, and Burggraeve. The fullest consideration of the subject is to be found in the dissertation of Poensgen.

In two cases of sudden death from gastric ulcer Jürgensen found gas in the veins and arteries of various parts of the body. He believes that this gas, which certainly was not the result of putrefaction after death, was derived from the stomach, and that it entered during life the circulation through vessels exposed in the borders of the ulcer, thus causing death. In one of the cases a profuse hemorrhage preceded death, and in the other the ulcer had perforated into the peritoneal cavity.⁸⁵

⁸⁵ Jürgensen does not consider whether this gas may not have made its way into the blood-vessels after death in a manner similar to its extension through the cellular tissue of the body in the cases of emphysema just mentioned. In the case which he has reported in full interstitial and subserous emphysema could be traced from the ulcer ("Luft im Blute," Deutsches Arch. f. klin. Med., Bd. 31, p. 441, 1882).

The source of hemorrhage from gastric ulcer is from blood-vessels either in the stomach itself or in the neighborhood of the stomach. Hemorrhages slight or of moderate severity occur from the capillaries and small arteries and veins in the mucous and submucous coats. Sometimes profuse and even fatal hemorrhage comes from arteries or from veins in the submucous coat, especially when these vessels are dilated. Quickly-fatal hemorrhages take place from the large vessels between the muscular and the serous coats, particularly from the main trunks on the curvatures. After the formation of adhesions, followed by the perforation of all of the coats of the stomach, profuse bleeding may proceed from the erosion of large vessels near the stomach, such as the splenic, the hepatic, the pancreatico-duodenal arteries, the portal and the splenic veins, and the mesenteric vessels. Bleeding may also occur from vessels in the parenchyma of organs invaded by the ulcer. The most common source of fatal hemorrhage is from the splenic artery, which from its position is peculiarly exposed to invasion by ulcers of the posterior wall of the stomach. The hemorrhage is usually arterial in origin. It may come from miliary aneurisms of the gastric arteries or from varicose veins in the wall of the stomach. As Cruveilhier has pointed out, an ulcer may cicatrize except over one spot corresponding to an artery from which fatal hemorrhage may occur. Ulcers which give rise to large hemorrhages are usually chronic in their course. Those seated on the middle of the anterior wall, although peculiarly liable to perforate, are comparatively exempt from hemorrhage on account of the small size of the blood-vessels there.

Changes in the blood-vessels of the stomach have been seen in a considerable number of cases of gastric ulcer. Instances have been recorded of the association with gastric ulcer of most of the diseases to which blood-vessels are subject. An example in all respects convincing of embolism of the artery supplying the ulcerated region of the stomach has not been published. Probably the best case belonging here is one of perforating ulcer of the stomach with hemorrhagic infiltration in its walls, presented by Janeway to the New York Pathological Society in 1871.⁸⁶ In this case there was in the gastro-epiploic artery an ante-mortem fibrinous plug which was continued into the nutrient artery of the ulcerated piece of the stomach. No source for an embolus could be found. In one case Merkel found an embolus in a small artery leading to an ulcer of the duodenum.⁸⁷ The arch of the aorta was atheromatous and contained a thrombus. Patches of hemorrhagic infiltration existed in the stomach.

⁸⁶ Trans. of the N.Y. Path. Soc., vol. ii. p. 1.

⁸⁷ Wiener med. Presse, vii. p. 30, 1866.

In many cases thrombosis of the arteries, and especially of the veins involved in the diseased tissue around an ulcer, has been observed, and in some the thrombus was prolonged in the vessels for a considerable distance from the ulcer. It is probable that in most of these cases the thrombus was secondary to the ulcer. Hyaline thrombosis of the capillaries near the ulcer is also to be mentioned.

In a certain, but not large, number of cases atheroma with calcification or with fatty degeneration of the arteries of the stomach has been found associated with gastric ulcer.⁸⁸ Reference has already been made to the occurrence of obliterating endarteritis in the thickened edges and floor of gastric ulcer, where it is doubtless secondary. In one case of gastric ulcer I found a widespread obliterating endarteritis affecting small and medium-sized arteries in many parts of the body, including the stomach.⁸⁹

⁸⁸ For cases in point see Norman Moore, Trans. of the Path. Soc. of London, vol. xxxiv. p. 94.

⁸⁹ On the posterior wall of the stomach, midway between the greater and the lesser curvature and five inches to the right of the cardiac orifice, was a round ulcer half an inch in diameter, with smooth, sharp edges. In the floor of the ulcer, which extended to the muscular coat, was a small perforated aneurism of a branch of the coronary artery. In addition there were small, granular kidneys, hypertrophied heart without valvular lesion, and chronic interstitial splenitis. Small and medium-sized arteries in the kidneys, spleen, heart, lymphatic glands, and stomach were the seat of a typical endarteritis obliterans, resulting in some instances in complete closure of the lumen of the vessel. The patient, who was attended by Sassdorf, was seized during the night with vomiting of blood, which continued at intervals for twenty-four hours until his death. The patient was a man about fifty years of age, without previous history of gastric ulcer or of syphilis.

In one case Powell⁹⁰ found a small aneurism of the coronary artery in an ulcer of the lesser curvature of the stomach. Hauser⁹¹ found an aneurismal dilatation of an atheromatous and thrombosed arterial twig in the floor of a recent ulcer. In my case of obliterating endarteritis just referred to there was a small aneurism in the floor of the ulcer. These miliary aneurisms in the floor of gastric ulcers seem to be analogous to those in the walls of phthisical cavities. Miliary aneurisms occur in the stomach independently of gastric ulcer, and may give rise to fatal hæmatemesis, as in four cases reported by Galliard.⁹²

⁹⁰ Trans. of the Path. Soc. of London, vol. xxix.

⁹¹ Das chronische Magengeschwür, etc., p. 11, Leipzig, 1883.

⁹² L'Union méd., Feb. 26, 1884. Curtis reported a case of fatal hæmatemesis from an aneurism, not larger than a small pea, seated in the cicatrix of an old ulcer (Med. Annals of Albany, Aug., 1880).

Gastric ulcer is occasionally associated with waxy degeneration of the arteries of the stomach.⁹³ In most of these cases there were multiple shallow ulcers. Hæmatemesis is generally absent in gastric ulcer resulting from waxy disease of the gastric blood-vessels. As is well known, the amyloid material itself resists the action of the gastric juice.

⁹³ Hauser (op. cit.) alludes to a case in which, with waxy degeneration of the stomach, over one hundred small ulcers were found in different stages of development, from hemorrhagic infiltrations to complete ulcers. Cases belonging here are reported by Fehr, Ueber die Amyloide Degeneration, Inaug. Diss., Bern, 1866; Merkel, Wiener med. Presse, 1869; Edinger, Deutsches Arch. f. klin. Med., Bd. 29, p. 568; Marchiafava, Atti del Accad. Med. di Roma, iii. p. 114; and Mattei, Deutsche med. Zeitung, July 5, 1883.

Finally, varicosities of the veins of the stomach have been once in a while found with gastric ulcer. In a large number, probably in the majority, of cases of gastric ulcer no changes have been found in the blood-vessels of the stomach except such as were manifestly secondary to the ulcer.

That gastric ulcer is frequently complicated with chronic catarrhal gastritis has been repeatedly mentioned in the course of this article.

PATHOGENESIS.—Without doubt, the most obscure chapter in the history of gastric ulcer is that relating to its origin and to its persistence. Notwithstanding a vast amount of investigation and of discussion, unanimity of opinion upon these subjects has not been reached. In view of this uncertainty it is desirable in this article to do little more than to summarize the leading theories as to the development of gastric ulcer.

Most observers are agreed that the digestive action of the gastric juice has some share in the development and the progress of the ulcer, but as to the first cause of the ulcer there are various hypotheses.

The earliest theory refers the origin of simple ulcer of the stomach to inflammation. Since its advocacy by Abercrombie and by Cruveilhier this theory has always had its adherents, particularly among French writers. It is true that in stomachs which are the seat of simple ulcer evidences of inflammation can often be found both in the neighborhood of the ulcer and elsewhere. In recent times the supporters of the inflammatory origin of gastric ulcer lay especial stress upon the presence of foci of infiltration with small round cells in the mucous and the submucous coats.⁹⁴ But it is difficult to explain by the inflammatory theory the usually solitary occurrence and the funnel-like shape of gastric ulcer.

⁹⁴ Laveran, Arch. de Phys. norm. et path., 1876, p. 443; Galliard, Essai sur la Pathogenie de l'Ulcère simple de l'Estomac, Thèse de Paris, 1882; Colombo, Annali univ. di Med., 1877.

The theory that gastric ulcer is of neurotic origin has also been advocated. Some refer the origin to the secretion of an excessively acid gastric juice under abnormal nervous influence (Günsburg), others to vaso-motor disturbances, and others to trophic disturbances. Wilks and Moxon compare simple gastric ulcer to ulcers of the cornea resulting from paralysis of the trigeminus. The neurotic theory of the origin of gastric ulcer is altogether speculative and has never gained wide acceptance.⁹⁵

⁹⁵ The first to attribute gastric ulcer to nervous influence was Siebert (Casper's Wochenschr. f. d. Heilk., 1842, No. 29, and Deutsche Klinik, 1852). Cf. also Günsburg, Arch. f. phys. Heilk., xi., 1852; Wilks and Moxon, Lect. on Path. Anat., 2d ed., Philada., 1875, p. 386. Osborne in 1845 attributed gastric ulcer to the secretion of an abnormally acid juice by a circular group of the gastric glands (Dublin Journ. of Med. Sci., vol. xxvii. p. 357).

The view which has met with the greatest favor is that which attributes the origin of gastric ulcer to impairment or arrest of the circulation in a circumscribed part of the wall of the stomach, and to a subsequent solution by the gastric juice of the part thus affected. Rokitansky first suggested this view by assigning hemorrhagic necrosis of the mucous membrane as the first step in the formation of the ulcer; but it is Virchow who has most fully developed this view and has given it its main support. The first cause of gastric ulcer, according to Virchow, is a hemorrhagic infiltration of the coats of the stomach induced by local disturbances in the circulation. The part the nutrition of which is thus impaired or destroyed is dissolved by the gastric juice.

The affections of the gastric blood-vessels to which importance has been attached are (a) embolism and thrombosis; (b) diseases of the coats of the vessels, as atheroma, obliterating endarteritis, fatty degeneration, amyloid degeneration, and aneurismal and varicose dilatations; (c) compression of the veins by spasm of the muscular coats of the stomach in vomiting and in gastralgia; (d) passive congestion of the stomach by obstruction in the portal circulation.

In support of this view are urged the following facts: First, it has been proven by the experiments of Pavy that parts of the gastric wall from which the circulation has been shut off undergo digestion; second, hemorrhagic infarctions have been observed in the stomach, both alone (Von Recklinghausen, Hedenius) and associated with gastric ulcer (Key, Rindfleisch); third, the hemorrhagic infiltration in the walls of recently-formed ulcers indicates a hemorrhagic origin; fourth, the funnel-like shape of the ulcer resembles the funnel-shaped area of distribution of an artery; fifth, gastric ulcers have been experimentally produced by injecting emboli into the gastric arteries (Panum, Cohnheim).⁹⁶

⁹⁶ Pavy, Philosoph. Trans., 1763, p. 161; V. Recklinghausen, Virchow's Archiv, Bd. 30, p. 368; Axel Key, Virchow und Hirsch's Jahresb., 1870, Bd. ii. p. 155; Rindfleisch, Lehrb. d. path. Gewebelehre, 5te Aufl., Leipzig, 1878; Panum, Virchow's Archiv, Bd. 25, p. 491; Cohnheim, Vorles. über allgem. Path., Bd. ii. p. 53, Berlin, 1880.

The main objections to this view are the infrequency with which the assumed changes in the blood-vessels have been demonstrated, the common occurrence of gastric ulcer at an age earlier than that at which diseases of the blood-vessels are usually present, and the absence of gastric ulcer in the vast majority of cases of heart disease, with widespread embolism of different organs of the body. To meet some of these objections, Klebs⁹⁷ presupposes in many cases a local spasmodic contraction of the gastric arteries, causing temporary interruption of the circulation; Rindfleisch and Axel Key, compression of the gastric veins, with resulting hemorrhagic infiltration by spasm of the muscular coat of the stomach in vomiting and in gastralgic attacks. But these are pure hypotheses.

⁹⁷ Handb. d. path. Anat., Bd. i. p. 185, Berlin, 1869.

What is actually known concerning diseases of the gastric blood-vessels in ulcer of the stomach has already been stated under the morbid anatomy. From this it may be inferred that the origin of gastric ulcer in diseased conditions of the blood-vessels has been established only for a comparatively small group of cases.

Böttcher's⁹⁸ view that gastric ulcer is of mycotic origin, being produced by micrococci, has thus far met with no confirmation.

⁹⁸ Dorpater med. Zeitschr., Bd. v. p. 148, 1874.

There are those who hold an eclectic view concerning the origin of gastric ulcer. They believe that ulcer of the stomach may be produced by a variety of causes, such as inflammation, circulatory disturbances, irritating substances introduced into the stomach, traumatism, etc. The peculiarities of the ulcer are due not to any specific cause, but to the solvent action of the gastric juice, which keeps clean the floor and the sides of the ulcer. These clean edges and floor, which are incident to all ulcers of the stomach, justify no conclusion as to the cause of the ulcer. Engel⁹⁹ over thirty years ago held that gastric ulcer might originate in various ways—that there was nothing specific about it. Brinton was also of similar opinion.

⁹⁹ Prager Vierteljahrschr., 1853, ii.

Gastric ulcers have been produced experimentally in animals in a variety of ways, but these experiments have not materially elucidated the pathenogenesis of ulcer in man. Schiff by lesions of various parts of the brain, and later Ebstein by lesions of many parts of the central and peripheral nervous system by injections of strychnine—in fact, apparently by any means which greatly increased the blood-pressure—produced in the stomachs of animals ecchymoses and ulcers. Müller by ligation of the portal vein, Pavy by ligation of arteries supplying the stomach, likewise produced hemorrhages and ulcers. The results of Pavy could not be confirmed by Roth and others. Panum, and afterward Cohnheim, produced gastric ulcers by introducing multiple emboli into the gastric arteries. Daettwyler under Quincke's direction caused, in dogs with gastric fistulæ, ulcers of the stomach by various mechanical, chemical, and thermic irritants applied to the inner surface of the stomach. Aufrecht observed hemorrhages and ulcers in the stomachs of rabbits after subcutaneous injections of cantharidin.¹⁰⁰

¹⁰⁰ Schiff, De vi motorea baseos encephali, 1845, p. 41; Ebstein, Arch f. exp. Path. u. Pharm., 1874, p. 183; Müller, Das corrosive Geschwür im Magen, etc., p. 273, Erlangen, 1860; Pavy, Guy's Hosp. Rep., vol. xiii., 1867; Roth, Virchow's Archiv, Bd. 45, p. 300, 1869; Panum, loc. cit.; Cohnheim, op. cit.; Daettwyler, Quincke, Deutsche med. Wochenschr., 1882, p. 79; Aufrecht, Centralbl. f. d. med. Wiss., 1882, No. 31.

The most interesting of these experiments are those of Cohnheim and of Daettwyler, who demonstrated that in one essential point all of these experimental ulcers differ from simple gastric ulcer in man—namely, in the readiness with which they heal. To this ready healing the gastric juice, much as it has been accused of causing the spread of gastric ulcers in man, seems to have offered no obstacle. We know that similar losses of substance in the human stomach heal equally well.¹⁰¹ Hence it has been maintained throughout this article that it is unjustifiable to regard all of the scars found in the human stomach as the result of simple ulcer.

¹⁰¹ Portions of the mucous membrane of the stomach, sometimes with some of the submucous coat, have been in several instances removed with the stomach-pump, but thus far no bad effects have followed.

It appears from these experiments, as well as from observations on man, that it is more difficult to explain why ulcers in the stomach do not heal than it is to understand how they may be produced. From this point of view the observation of Daettwyler is of interest, that in dogs which had been rendered anæmic by repeated abstraction of blood not only did slighter irritants suffice to produce ulcers of the stomach, but the ulcers healed much more slowly. Practically, it is important to learn what are the obstacles to the repair of gastric ulcers, but our positive knowledge of these is slight. It is probable that such obstacles are to be found in constitutional causes, such as anæmia and chlorosis, in abnormal states of the blood-vessels around the ulcer, in catarrhal affections of the stomach, in irritating articles of food, in improper modes of living, and in increased acidity of the gastric juice.

DIAGNOSIS.—In many cases the diagnosis of gastric ulcer can be made with reasonable certainty; in other cases the diagnosis amounts only to a suspicion more or less strong, and in still other cases the diagnosis is impossible.

The diagnostic symptoms are epigastric pain, vomiting, and gastric hemorrhage. The characteristics of the pain which aid in the diagnosis are its fixation in one spot in the epigastric region, its onset soon after eating, its dependence upon the quantity and the quality of the food, its relief upon the complete expulsion of the contents of the stomach, its alleviation by changes in posture, and its increase by pressure. That the pain of gastric ulcer has not always these characteristics has been mentioned under the Symptomatology. Vomiting without hæmatemesis is the least characteristic of these symptoms. It aids in the diagnosis when it occurs after eating at the acme of a gastralgic attack and is followed by the relief of pain. Hæmatemesis is the most valuable symptom in diagnosis. The more profuse the hemorrhage and the younger the individual in whom it occurs, the greater is the probability of gastric ulcer. It should not be forgotten that the blood is sometimes discharged solely by the stools.

The simultaneous occurrence of all these symptoms renders the diagnosis of gastric ulcer easy.¹⁰² In all cases in which gastrorrhagia is absent the diagnosis is uncertain; but gastric ulcer should be suspected whenever the ingestion of food is followed persistently by severe epigastric pain and other causes of the pain have not been positively determined. When the course of the ulcer is latent and when the symptoms are only those of dyspepsia, the diagnosis is of course impossible. In cases previously obscure a diagnosis in extremis is sometimes made possible by the occurrence of perforation of the stomach.

¹⁰² That even under the most favorable circumstances absolute certainty in the diagnosis of gastric ulcer is not reached is illustrated by a case reported with great precision and fulness by Banti: A female servant, twenty-one years old, had every symptom of gastric ulcer, including repeated hæmatemesis and the characteristic epigastric pain. She was nourished by enemata. She died from an ulcerative proctitis four days after the last hemorrhage from the stomach. Only a slight catarrhal inflammation of the stomach was found at the autopsy, without trace of ulcer, cicatrix, or ecchymosis ("Di un Caso d'Ematemesi," La Sperimentale, Feb., 1880, p. 168). It would seem as if there must have been an ulcer which had healed so completely as to leave no recognizable scar.

In making a differential diagnosis of gastric ulcer, as well as of any disease, reliance should be placed more upon the whole complexion of the case than upon any fancied pathognomonic symptoms.

The diseases which are most difficult to distinguish from gastric ulcer are nervous affections of the stomach. Like gastric ulcer, most of these are more common in women than in men, and especially in chlorotic women with disordered menstruation and with hysterical manifestations. These nervous affections are manifold and their leading characteristics are not yet well defined. The most important of these affections are nervous dyspepsia, nervous vomiting, nervous gastralgia, and gastric crises.

The leading symptoms of nervous dyspepsia, as described by Leube,¹⁰³ are the ordinary symptoms of dyspepsia without evidence of anatomical alteration of the stomach, and with the proof by washing out the stomach that the process of digestion is not delayed. Nervous dyspepsia is often associated with other nervous affections, and is caused especially by influences which depress the nervous system. Epigastric pain, and especially tenderness on pressure over the stomach, are not common symptoms in nervous dyspepsia. Only those rare cases of gastric ulcer in which hemorrhage from the stomach is absent and epigastric pain is not prominent are likely to be confounded with nervous dyspepsia. In such cases, although the diagnosis of nervous dyspepsia is by far the most probable, the patient may be confined to bed and put upon the strict regimen for gastric ulcer. If in the course of ten days or two weeks essential relief is not obtained, ulcer may be excluded, and the proper treatment for nervous dyspepsia with tonics and electricity may be adopted (Leube).

¹⁰³ Deutches Arch. f. klin. Med., Dec. 18, 1878.

In nervous vomiting, which occurs most frequently in hysterical women, other nervous manifestations are present; there are usually less epigastric pain and tenderness than in ulcer; the nutrition is better preserved; the vomiting is less dependent upon the ingestion of food and more dependent on mental states; and there are longer intervals of relief than in ulcer. Still, it may be necessary to resort to the therapeutical diagnosis as in the preceding instance.

In this connection attention may be called to the importance of searching for reflex causes of vomiting, such as beginning phthisis, ovarian or uterine disease, cerebral disease, and pregnancy; also to certain cases of chronic Bright's disease in which gastric disturbances are the main symptoms.

Of all the nervous affections of the stomach, nervous gastralgia is the one which presents the greatest similarity to gastric ulcer. Its diagnosis from gastric ulcer is often extremely difficult, and may be impossible. The points of difference given in the following table may aid in the diagnosis:

NERVOUS GASTRALGIA.	ULCER OF THE STOMACH.
1. Pain is often independent of the ingestion of food, and may even be relieved by taking food.	1. Pain is mostly dependent upon taking food, and its intensity varies with the quality and the quantity of the food.
2. Pain is often relieved by firm pressure.	2. Pain is increased by pressure.
3. Pain is rarely relieved by vomiting.	3. Pain after a meal is usually relieved by vomiting.
4. Fixed point of tenderness and of subjective pain not generally present.	4. These are often present.
5. Relief is usually complete between the paroxysms.	5. Some pain often continues between the paroxysms.
6. Nutrition frequently well preserved.	6. Nutrition usually affected.
7. Usually associated with other nervous affections, such as hysteria, neuralgia in other places, ovarian tenderness, etc.	7. Neuropathic states less constantly present.
8. Benefited less by regulation of diet than by electricity and tonic treatment.	8. Benefited not by electricity, but by regulation of diet.
9. Not followed by dilatation of stomach.	9. Dilatation of stomach may supervene.

According to Peter,¹⁰⁴ the surface temperature of the epigastrium is elevated in gastric ulcer, but not in nervous gastralgia.

¹⁰⁴ Gaz. des Hôp., June, 1883.

Probably not a single one of the points mentioned in the table is without exception. Nervous gastralgia may be associated with gastric ulcer, and if the ulcer is otherwise latent the diagnosis is manifestly impossible. A diagnosis of purely functional gastralgia has been repeatedly overthrown by the occurrence of profuse hæmatemesis. There is no symptom upon which it is more unsatisfactory to base a diagnosis than upon pain. There is much difference among physicians as regards the frequency with which they diagnose gastric ulcer in the class of cases here described. It is probable that the error is oftenest a too frequent diagnosis of gastric ulcer than the reverse. Nevertheless, when there is doubt it is well to submit the patient for a time to the proper treatment for gastric ulcer.

In several instances gastric crises have been mistaken for gastric ulcer. These gastric or gastralgic crises, as they are called by Charcot, by whom they have been best described,¹⁰⁵ are most frequently associated with locomotor ataxia, but they may occur in connection with other diseases of the spinal cord (subacute myelitis, general spinal paralysis, and disseminated sclerosis), and an analogous affection has been described by Leyden¹⁰⁶ as an independent disease under the name of periodical vomiting with severe gastralgic attacks. Gastric crises have been most carefully studied as a symptom in the prodromic stage of locomotor ataxia. The distinguishing features of these crises are the sudden onset and the atrocious severity of the gastric pain; the simultaneous occurrence of almost incessant vomiting; the habitual continuance of the paroxysms, almost without remission, for two or three days; the normal performance of the gastric functions in the intervals between the paroxysms, which may be months apart; the frequent association with other prodromic symptoms of locomotor ataxia, such as ocular disorders and fulgurating pains in the extremities; and the development after a time of ataxia. Leyden has observed during the attacks retraction of the abdomen without tension of the abdominal walls, obstinate constipation, scanty, dark-colored urine, even anuria for twenty-four hours, and increased frequency of the pulse (also noted by Charcot). Vulpian¹⁰⁷ mentions a case in which there was vomiting of dark-colored blood, and in which naturally the diagnosis of gastric ulcer had been made. In the autopsies of Leyden and of Charcot no lesions of the stomach have been found.

The differential diagnosis of gastric ulcer from gastric cancer will be considered in the article on GASTRIC CANCER.

It has already been said that a part of the symptoms of gastric ulcer are due to an associated chronic catarrhal gastritis. Usually other symptoms are present which render possible the diagnosis of the ulcer. There is usually some apparent external or internal cause of chronic catarrhal gastritis, whereas the etiology of ulcer is obscure; in chronic gastritis gastralgic paroxysms and the peculiar fixed epigastric pain of gastric ulcer are usually absent; in chronic gastritis profuse hæmatemesis is a rare occurrence; and in gastritis the relief obtained by rest and proper regulation of the diet, although manifest, is usually less immediate and striking than in most cases of gastric ulcer.

The passage of gall-stones is usually sufficiently distinguished from gastric ulcer by the sudden onset and the sudden termination of the pain, by the situation of the pain to the right of the median line, by the complete relief in the intervals between the attacks, by the occurrence of jaundice, by the recognition sometimes of enlargement of the liver and of the gall-bladder, and by the detection of gall-stones in the feces.

There is not much danger of confounding abdominal aneurism and lead colic with gastric ulcer, and the points in their differential diagnosis are sufficiently apparent to require no description here. The diagnosis of duodenal ulcer from gastric ulcer will be discussed elsewhere. The different causes of gastric hemorrhage, a knowledge of which is essential to the diagnosis of gastric ulcer, will be considered in the article on HEMORRHAGE FROM THE STOMACH.

PROGNOSIS.—Although a decided majority of simple ulcers of the stomach cicatrize, nevertheless, in view of the frequently insidious course of the disease, the sudden perforations, the grave hemorrhages, the relapses, and the sequels of the disease, the prognosis must be pronounced serious.

The earlier the ulcer comes under treatment the better the prognosis. Old ulcers with thickened indurated margins containing altered blood-vessels naturally heal with greater difficulty than recently-formed ulcers.

Profuse hemorrhage adds to the gravity of the diagnosis. It usually indicates that the ulcer has penetrated to the serous coat of the stomach. A hemorrhage may exert a favorable influence, in so far as to convince the patient of the necessity of submitting to the repose and the strict dietetic regimen which the physician prescribes.

The severity of the pain is of little value as a prognostic sign. Vomiting and dyspepsia, if uncontrolled by regulation of the diet, lead to a cachectic state which often ends in death.

Little basis as there is to hope for recovery after perforation into the general peritoneal cavity, there nevertheless have been a very few cases in which there is reason to believe that recovery has actually taken place after this occurrence.¹⁰⁸

¹⁰⁸ The most convincing case of recovery after perforation of gastric ulcer is one reported by Hughes, Ray, and Hilton in Guy's Hosp. Rep., 1846, p. 332. A servant-girl was suddenly seized with all of the symptoms of perforation. Fortunately, she had eaten nothing for four hours before the attack, and then only gruel. She was placed at once under the influence of opium, was kept in the recumbent posture, and was fed by the rectum. She was discharged apparently cured after fifty-two days. Two months afterward she was again suddenly seized with the same symptoms, and she died in fourteen hours. Shortly before the second perforation she had eaten cherries, strawberries, and gooseberries, which were found in the peritoneal cavity. The autopsy showed, in addition to a recent peritonitis, evidences of an old peritonitis. There were adhesions of the coils of the intestines with each other and between the stomach and adjacent viscera. In the stomach were found a cicatrix and two open ulcers, one of which had perforated.

Other cases in which recovery followed after all of the symptoms of perforation of gastric ulcer were present, but in which no subsequent autopsy proved the correctness of the diagnosis, have been reported by Redwood (Lancet, May 7, 1870); Ross (ibid., Jan. 21, 1871); Tinley (ibid., April 15, 1871); Mancini (La Sperimentale, 1876, pp. 551, 665); and G. Johnson (Brit. Med. Journ., March 26, 1870).

Frazer's two cases, reported in the Dublin Hosp. Gaz., April 15, 1861, are not convincing. The case reported by Aufrecht (Berl. kl. Wochenschr., 1870, No. 21) and the one by Starcke (Deutsche Klinik, 1870, No. 39), which are sometimes quoted as examples of recovery, were cases of circumscribed peritonitis following perforation.

In an interesting case from Nothnägel's clinic reported by Lüderitz, the patient lived sixteen days after perforation into the peritoneal cavity, followed by all of the symptoms of diffuse perforative peritonitis. Death resulted from pneumonia secondary to the peritonitis. At the autopsy were found adhesions over the whole peritoneal surface and streaks of thickened pus between the coils of intestine. The perforation in the stomach was closed by the left lobe of the liver (Berl. kl. Wochenschr., 1879, No. 33).

In estimating the prognosis one should bear in mind the possibility of relapses; of a continuance of gastric disorders, particularly of gastralgia, after cicatrization; of the formation of cicatricial stenosis of the orifices of the stomach; and of the development of dilatation of the stomach.

After the worst has been said concerning the unfavorable issues of gastric ulcer, it yet remains true that the essential tendency of the ulcer when placed under favorable conditions is toward recovery, and that in many cases the treatment of the disease affords most excellent results, and is therefore a thankful undertaking for the physician.

TREATMENT.—In the absence of any agent which exerts a direct curative influence upon gastric ulcer the main indication for treatment is the removal of all sources of irritation from the ulcer, so that the process of repair may be impeded as little as possible.

Theoretically, this is best accomplished by giving to the stomach complete rest and by nourishing the patient by rectal alimentation. Practically, this method of administering food is attended with many difficulties, and, moreover, the nutrition of the patient eventually suffers by persistence in its employment. In most cases the patient can be more satisfactorily nourished by the stomach, and by proper selection of the diet, without causing injurious irritation of the ulcer.

At the beginning of the course of treatment it is often well to withhold for two or three days all food from the stomach and to resort to exclusive rectal feeding. In some cases with uncontrollable vomiting and after-hemorrhage from the stomach it is necessary to feed the patient exclusively by the rectum.

The substances best adapted for nutritive enemata are artificially-digested foods, such as Leube's pancreatic meat-emulsion, his beef-solution, and peptonized milk-gruel as recommended by Roberts.¹⁰⁹ Beef-tea and eggs, which are often used for this purpose, are not to be recommended, as the former has very little nutritive value, and egg albumen is absorbed in but slight amount from the rectum. Expressed beef-juice may also be used for rectal alimentation. The peptones, although physiologically best adapted for nutritive enemata, often irritate the mucous membrane of the rectum, so that they cannot be retained. It has been proven that it is impossible to completely nourish a human being by the rectum.¹¹⁰ Rectal alimentation can sometimes be advantageously combined with feeding by the mouth.

¹⁰⁹ Leube's pancreatic meat-emulsion is prepared by adding to 4-8 ounces of scraped and finely-chopped beef l-2½ ounces of fresh finely-chopped oxen's or pig's pancreas freed from fat. To the mixture is added a little lukewarm water until the consistence after stirring is that of thick gruel. The syringe used to inject this mixture should have a wide opening in the nozzle; Leube has constructed one for the purpose (Leube, Deutsches Arch. f. klin. Med., Bd. x. p. 11).

The milk-gruel is prepared by adding a thick, well-boiled gruel made from wheaten flour, arrowroot, or some other farinaceous article to an equal quantity of milk. Just before administration a dessertspoonful of liquor pancreaticus (Benger) or 5 grains of extractum pancreatis (Fairchild Bros.), with 20 grains of bicarbonate of soda, are added to the enema. This may be combined with peptonized beef-tea made according to Roberts's formula (Roberts, On the Digestive Ferments, p. 74, London, 1881).

Preparatory to beginning the treatment the bowels should be emptied by a clyster, and this should be occasionally repeated. About three to six ounces of the tepid nutritive fluid should be slowly injected into the rectum. The injections may be repeated at intervals of from three to six hours. If necessary, a few drops of laudanum may be occasionally added to the enema.

There is universal agreement that the dietetic treatment of gastric ulcer is of much greater importance than the medicinal treatment. There is hardly another disease in which the beneficial effects of proper regulation of the diet are so apparent as in gastric ulcer. Those articles of food are most suitable which call into action least vigorously the secretion of gastric juice and the peristaltic movements of the stomach, which do not cause abnormal fermentations, which do not remain a long time in the stomach, and which do not mechanically irritate the surface of the ulcer. These requirements are met only by a fluid diet, and are met most satisfactorily by milk and by Leube's beef-solution.

The efficacy of a milk diet in this disease has been attested by long and manifold experience. By its adoption in many cases the pain and the vomiting are relieved, and finally disappear, and the ulcer heals. In general, fresh milk is well borne. If not, skimmed milk may be employed. If the digestion of the milk causes acidity, then a small quantity of bicarbonate of soda or some lime-water (one-fourth to one-half in bulk) may be added to the milk. Large quantities should not be taken at once. Four ounces of milk taken every two hours are generally well borne. Sometimes not more than a tablespoonful can be taken at a time without causing vomiting, and then of course the milk should be given at shorter intervals. It is desirable that the patient should receive at least a quart, and if possible two quarts, during the twenty-four hours. The milk should be slightly warmed, but in some cases cold milk may be better retained. In some instances buttermilk agrees with the patient better than sweet milk. Although many suppose that they have some idiosyncrasy as regards the digestion of milk, this idiosyncrasy is more frequently imaginary than real. Still, there are cases in which milk cannot be retained, even in small quantity.

For such cases peptonized milk often proves serviceable.¹¹¹ The artificial digestion of milk as well as of other articles of food is a method generally applicable to the treatment of gastric ulcer. The main objection to peptonized milk is the aversion to it that many patients acquire on account of its bitter taste. The peptonization should not be carried beyond a slightly bitter taste. The disagreeable taste may be improved by the addition of a little Vichy or soda-water. Peptonized milk has proved to be most valuable in the treatment of gastric ulcer.

¹¹¹ Milk may be peptonized by adding to a pint of fresh milk, warmed to a temperature of 100° F., 5 grs. of extract pancreatis (Fairchild Bros. and Foster) and 20 grs. of bicarb. sodii dissolved in 4 ounces of tepid water. The mixture is allowed to digest for about an hour at a temperature of 100° F., which may be conveniently done by placing the milk in a bowl in a pan of water maintained at this temperature. It is then boiled, strained, and placed on ice, or when the milk is to be taken immediately it is better not to boil it, in order that the partial digestion may continue for a while under the influence of the pancreatic ferment in the stomach. The milk without boiling may be kept on ice without further digestion; and this procedure has the advantage that the pancreatic ferments, although inactive at a temperature near that of ice, are not destroyed. The degree of digestion aimed at is indicated by the production of a slightly, but not unpleasantly, bitter taste. When the digestion is carried to completion, milk has a very bitter and disagreeable flavor. Peptonized milk-gruel, mentioned on page [519], may also be employed.

Leube's beef-solution¹¹² is a nutritious, unirritating, and easily-digested article of diet. It can often be taken when milk is not easily or completely digested, or when milk becomes tiresome and disagreeable to the patient. It is relied upon mainly by Leube in his very successful treatment of gastric ulcer. A pot of the beef-solution (corresponding to a half pound of beef) is to be taken during the twenty-four hours. A tablespoonful or more may be given at a time in unsalted or but slightly salted bouillon, to which, if desired, a little of Liebig's beef-extract may be added to improve the taste. The bouillon should be absolutely free from fat. Unfortunately, not a few patients acquire such a distaste for the beef-solution that they cannot be persuaded to continue its use for any considerable length of time.

¹¹² By means of a high temperature and of hydrochloric acid the meat enclosed in an air-tight vessel is converted into a fine emulsion and is partly digested. Its soft consistence, highly nutritious quality, and easy digestibility render this preparation of the greatest value. The beef-solution is prepared in New York satisfactorily by Mettenheimer, druggist, Sixth Avenue and Forty-fifth street, and by Dr. Rudisch, whose preparation is sold by several druggists.

Freshly-expressed beef-juice is also a fairly nutritious food, which can sometimes be employed with advantage. The juice is rendered more palatable if it is pressed from scraped or finely-chopped beef which has been slightly broiled with a little fresh butter and salt. The meat should, however, remain very rare, and the fat should be carefully removed from the juice.

To the articles of diet which have been mentioned can sometimes be added raw or soft-boiled egg in small quantity, and as an addition to the milk crumbled biscuit or wheaten bread which may be toasted, or possibly powdered rice or arrowroot or some of the infant farinaceous foods, such as Nestle's. Milk thickened with powdered cracker does not coagulate in large masses in the stomach, and is therefore sometimes better borne than ordinary milk.

For the first two or three weeks at least the patient should be confined strictly to the bill of fare here given. Nothing should be left to the discretion of the patient or of his friends. The treatment should be methodic. It is not enough to direct the patient simply to take easily-digested food, but precise directions should be given as to what kind of food is to be taken, how much is to be taken at a time, how often it is to be taken, and how it is to be prepared.

In all cases of any severity the patient should be treated in bed in the recumbent posture, and warm fomentations should be kept over the region of the stomach. Mental and physical fatigue should be avoided.

Usually, at the end of two or three weeks of this diet the patient's condition is sufficiently improved to allow greater variety in his food. Meat-broths may be given. Boiled white meat of a young fowl can now usually be taken, and agreeable dishes can be prepared with milk, beaten eggs, and farinaceous substances, such as arrowroot, rice, corn-starch, tapioca, and sago. Boiled sweetbread is also admissible. Boiled calf's brain and calf's feet are allowed by Leube at this stage of the treatment.

To these articles can soon be added a very rare beefsteak made from the soft mass scraped by a blunt instrument from a tenderloin of beef, so that all coarse and tough fibres are left behind. This may be superficially broiled with a little fresh butter. Boiled white fish, particularly cod, may also be tried.

It is especially important to avoid all coarse, mechanically-irritating food, such as brown bread, wheaten grits, oatmeal, etc.; also fatty substances, pastry, acids, highly-seasoned food, vegetables, fruit, and all kinds of spirituous liquor. The juice of oranges and of lemons can usually be taken. The food should not be taken very hot or very cold.

For at least two or three months the patient should be confined to the easily-digested articles of diet mentioned. These afford sufficient variety, and no license should be given to exceed the dietary prescribed by the physician. Transgression in this respect is liable to be severely punished by return of the symptoms. When there is reason to believe that the ulcer is cicatrized, the patient may gradually resume his usual diet, but often for a long time, and perhaps for life, he may be compelled to guard his diet very carefully, lest there should be a return of the disease. Should there be symptoms of a relapse, the patient should resume at once the easily-digested diet described above.

Medicinal treatment of gastric ulcer, although less efficacious than the dietetic treatment, is not to be discarded. Since its advocacy by Ziemssen the administration of Carlsbad salts or of similarly composed salts belongs to the systematic treatment of gastric ulcer. The objects intended to be accomplished by the use of these salts are the daily evacuation of the contents of the stomach into the intestine by gentle stimulation of the gastric peristaltic movements, the neutralization of the acid of the stomach, and the prevention of acid fermentations in the stomach. Of these objects the most important is the prevention of stagnation of the contents of the stomach. The chief ingredients of the Carlsbad waters are sulphate of sodium, carbonate of sodium, and chloride of sodium. The most important of these ingredients is sulphate of sodium (Glauber's salts), which by exciting peristalsis propels the gastric contents into the intestine, and thus relieves the stomach of its burden, prevents fermentation, and removes from the surface of the ulcer an important source of irritation. The carbonate of sodium neutralizes the acids of the stomach, but the main value of this ingredient and of the chloride of sodium is that in some way they correct the action of the Glauber's salts, so that the latter may be taken in smaller quantity and without the usual unpleasant effects of pure Glauber's salts.¹¹³ The artificial Carlsbad salts are to be preferred to the natural or the artificial Carlsbad water. The natural Carlsbad salts and much of those sold as artificial Carlsbad salts consist almost wholly of sulphate of sodium. It is therefore best to prescribe in proper proportion the leading ingredients of these salts. A suitable combination is sulphate of sodium five ounces, bicarbonate of sodium two ounces, and chloride of sodium one ounce (Leichtenstern¹¹⁴). The relative proportion of the ingredients may of course be varied somewhat to suit individual cases. The salts are to be taken daily before breakfast dissolved in a considerable quantity of warm water. One or two heaping teaspoonfuls of the salts are dissolved in one-half to one pint of water warmed to a temperature of 95° F. One-fourth of this is to be drunk at a time at intervals of ten minutes. Breakfast is taken half an hour after the last draught. After breakfast there should follow one or two loose movements of the bowels. If this is not the case, the next day the quantity of the salts is to be increased, or if more movements are produced the quantity is to be diminished until the desired result is obtained. In case the salts do not operate, an enema may be used. Usually, to obtain the same effect, the quantity of salts may be gradually diminished to a teaspoonful.

¹¹³ Water from the Sprudel spring contains in 16 ounces 18.2 grains of sulphate of sodium, 14.6 grains of bicarbonate of sodium, and 7.9 grains of chloride of sodium, and 11.8 cubic inches of carbonic acid. Its natural temperature is 158° F. The other Carlsbad springs have the same fixed composition and vary only in temperature and amount of CO₂.

¹¹⁴ The second edition of the German Pharmacopoeia contains a formula for making artificial Carlsbad salts, so that the ingredients are in about the same proportion as in the natural water. The formula is as follows: Dried sulphate of sodium 44 parts, sulphate of potassium 2 parts, chloride of sodium 18 parts, bicarbonate of sodium 36 parts. These should be mixed so as to make a white dry powder. The Carlsbad water is imitated by dissolving 6 grammes of this salt in 1 liter of water (Pharmacopoeia Germanica, editio altera, Berlin, 1882, p. 232).

According to a prescription very commonly used in Germany, the Carlsbad salts are made by taking sulphate of sodium 50 parts, bicarbonate of sodium 6 parts, chloride of sodium 3 parts. Dose, a teaspoonful dissolved in one or two tumblers of warm water (Ewald u. Lüdecke, Handb. d. Allg. u. spec. Arzneiverordnungslehre, Berlin, 1883, p. 480).

The Carlsbad salts are directed especially against the chronic gastric catarrh which complicates the majority of cases of ulcer of the stomach. It is well known that the most effective method of treating this morbid condition is the washing out of the stomach by means of the stomach-tube. The propriety of adopting this procedure in gastric ulcer comes, therefore, under consideration. Although the use of the stomach-tube in gastric ulcer is discarded by Leube and by Sée on account of its possible danger, nevertheless this instrument has been employed with great benefit in many instances of this disease by Schliep, Debore, and others.¹¹⁵ No instance of perforation of an ulcer by means of the stomach-tube has been reported, and in general no evil effects have resulted; but Duguet cites a case of fatal hemorrhage following washing out of the stomach.¹¹⁶ In view of the great benefit to be secured by washing out the stomach, and of the comparatively slight danger which attends the process, it seems justifiable to adopt this procedure cautiously and occasionally in cases of gastric ulcer with severe gastric catarrh. Of course only the soft rubber tube should be used, and the siphon process should be adopted.¹¹⁷ The stomach may be washed out with pure warm water or with water containing a little bicarbonate of sodium (one-half drachm to a quart of water). The occasional cleansing of the stomach in this way can hardly fail to promote the healing of the ulcer. Recent or threatened hemorrhage from the stomach would contraindicate the use of the stomach-tube.

¹¹⁶ Gaz. des Hôp., Apr. 29, 1884. In a case of gastric ulcer of Cornillon severe hemorrhage followed washing out the stomach (Le Prog. méd., Apr. 28, 1883).

¹¹⁷ Soft rubber stomach-tubes are made by Tiemann & Co. in New York, and are sold by most medical instrument-makers. A description of the appropriate tube and of the method of its use is given by W. B. Platt ("The Mechanical Treatment of Diseases of the Stomach," Maryland Medical Journal, March 8, 1884).

Beyond the measures indicated there is little more to do in the way of treatment directed toward the repair of the ulcer. Not much, if anything, is to be expected from the employment of drugs which have been claimed to exert a specific curative action on the ulcer. Of these drugs those which have been held in the greatest repute are bismuth and nitrate of silver. Trousseau¹¹⁸ devised a somewhat complicated plan for administering bismuth and nitrate of silver in succession for several months in the treatment of gastric ulcer. There are few who any longer cherish any faith in these drugs as curative of gastric ulcer. The same may be said of other drugs which have been thought to have similar specific virtue in the treatment of gastric ulcer, such as acetate of lead, arsenic, chloral hydrate, iodoform, etc.

It remains to consider therapeutic measures which may be necessary to combat individual symptoms of gastric ulcer.

The pain of gastric ulcer is generally relieved in a few days by strict adherence to the dietetic regimen which has been laid down. When this is not the case, it may be best to withhold all food from the stomach and to nourish by the rectum. But this cannot be continued long without weakening the patient, and sometimes the pain persists in spite of the rest afforded the stomach. Undoubtedly, the most effective means of quieting the pain of gastric ulcer is the administration of opium in some form. Opium should not, however, be resorted to without full consideration of the possible consequences. When the use of this drug is once begun, the patient is liable to become dependent upon it, and may be inclined, consciously or unconsciously, to exaggerate the pain in order to obtain the narcotic. When prescribing opium in this disease the physician should have in mind the danger of establishing the opium habit. Moreover, opium retards digestion, and is anything but an aid to the proper dietetic regimen, which is all-important. If it is decided to give opium, it does not matter much in what form it is administered, but the dose should be as small as will answer the purpose. Hypodermic injections of morphine over the region of the stomach may be recommended. Codeia often produces less disturbance than opium or morphine. A useful powder for the relief of pain is one containing 8 or 10 grains of subnitrate of bismuth, ¹/12 grain of sulphate of morphia, and ¹/5 grain of extract of belladonna. Much of the beneficial effect attributed to bismuth is in reality due to its customary combination with a small quantity of morphine. Before resorting to opium in cases of severe pain it will be well to try some of the other means for relieving the pain of gastric ulcer, although they are less effective. Gerhardt thinks that astringents are better than narcotics to relieve the pain of ulcer, and he recommends for the purpose three or four drops of solution of chloride of iron diluted with a wineglassful of water, to be taken several times daily. Although this recommendation is from high authority and is often quoted, sufficient confirmatory evidence of its value is lacking. Other medicines recommended are hyoscyamus, belladonna, choral hydrate, chloric ether, hydrocyanic acid, bismuth, nitrate of silver, and compound kino powder. Sometimes warm fomentations, at other times a light ice-bag over the epigastrium, afford marked relief of the pain. Counter-irritation over the region of the stomach has also given relief. This may be effected with a mustard plaster or by croton oil. I have known the establishment of a small nitric-acid issue in the pit of the stomach to relieve the pain, but such severe measures of counter-irritation are generally unnecessary. The application of a few leeches over the epigastrium has been highly recommended, but this should be done without much loss of blood. The effect of position of the body upon the relief of pain should be determined. When the pain is due to flatulence or to acid fermentation in the stomach, the treatment should be directed to those states.

The most effective means of controlling the vomiting in gastric ulcer are the regulation of the diet and, if necessary, the resort to rectal alimentation. Absolute rest should be enjoined. Whenever small quantities of milk, peptonized or in any other form, cannot be retained, then exclusive rectal feeding may be tried for a while. There have been cases of gastric ulcer when both the stomach and the rectum have been intolerant of food. In such desperate cases the attempt may be made to introduce food into the stomach by means of the stomach-tube, for it is a singular fact that food introduced in this way is sometimes retained when everything taken by the mouth is vomited.¹¹⁹ The cautious washing out of the stomach by the stomach-tube may prove beneficial. In these cases the attempt has also been made to nourish by subcutaneous injections of food. In a case of gastric ulcer where no food could be retained either by the stomach or by the rectum Whittaker¹²⁰ injected subcutaneously milk, beef-extract, and warmed cod-liver oil. The oil was best borne. The injections were continued for four days without food by the mouth or rectum. The patient recovered. At the best, hypodermic alimentation can afford but slight nourishment, and is to be regarded only as a last refuge. If there is danger of death by exhaustion, transfusion may be resorted to.

¹¹⁹ Debore, L'Union médicale, Dec. 30, 1882, and Gaz. des Hôp., April 29, 1884. For this reason Debore makes extensive use of the stomach-tube in general in feeding patients affected with gastric ulcer. He objects to an exclusive milk diet on account of the quantity of fluid necessary to nourish the patient, which he says amounts to three to four quarts of milk daily. To avoid these inconveniences, he gives three times daily drachm viss of meat-powder and drachm iiss of bicarbonate of sodium (or equal parts of calcined magnesia and bicarb. sod.), well stirred into milk. This is to be introduced by the stomach-tube on account of its disagreeable taste. He believes that the addition of the large quantity of alkali prevents digestion from beginning until the food has reached the intestine. He also gives daily a quart of milk containing grs. xv of saccharate of lime. Debore's method of preparing the meat-powder is described in L'Union médicale, July 29, 1882, p. 160. He also uses a milk-powder (ibid., Dec. 30, 1882; see also Le Progrès méd., July 12, 1884).

¹²⁰ J. T. Whittaker, "Hypodermic Alimentation," The Clinic, Jan. 22, 1876.

Bernutz practised successfully in two cases the hypodermic injection of fresh dog's blood (Gaz. des Hôp., 1882, No. 64).

Krueg (Wiener med. Wochenschr., 1875, No. 34) injected 15 cc. of olive oil twice a day subcutaneously without causing abscesses.

Menzel and Porco were the first to employ hypodermic alimentation (ibid., 1869, No. 31).

Of remedies to check vomiting, first in importance are ice swallowed in small fragments and morphine administered hypodermically. Effervescent drinks, such as Vichy, soda-water, and iced champagne, may bring relief. Other remedies which have been recommended are bismuth, hydrocyanic acid, oxalate of cerium, creasote, iodine, bromide of potash, calomel in small doses, and ingluvin. But in general it is best to forego the use of drugs and to rely upon proper regulation of the diet, such as iced milk taken in teaspoonful doses, and upon repose for the stomach.

Hemorrhage from the stomach is best treated by absolute rest, the administration of bits of ice by the mouth, and the application of a flat, not too heavy, ice-bag over the stomach. The patient should lie as quietly as possible in the supine position, with light coverings and in a cool atmosphere. He should be cautioned to make no exertion. His apprehensions should be quieted so far as possible. All food should be withheld from the stomach, and for four or five days after the cessation of profuse hemorrhage aliment should be given only by the rectum. There is no proof that styptics administered by the mouth have any control over the hemorrhage, and as they are liable to excite vomiting they may do harm. Ergotin, dissolved in water (1 part to 10), may be injected hypodermically in grain doses several times repeated if necessary. If internal styptics are to be used, perhaps the best are alum-whey and a combination of gallic acid 10 grains and dilute sulphuric acid 10 drops diluted with water. Fox praises acetate of lead, and others ergot, tannin, and Monsell's solution. If there is vomiting or much restlessness, morphine should be given hypodermically. If the bleeding is profuse, elastic ligatures may be applied for a short time around the upper part of one or more extremities, so as to shut out temporarily from the circulation the blood contained in the extremity. If syncope threatens, ammonia or a little ether may be inhaled, or ether may be given hypodermically. Brandy, if administered, should be given either by the rectum or hypodermically. Caution should be exercised not to excite too vigorously the force of the circulation, as the diminished force of the heart is an important agent in checking hemorrhage. When life is threatened in consequence of the loss of blood, then recourse may be had to transfusion, but experience has shown that this act is liable to cause renewed hemorrhage in consequence of the elevation of the blood-pressure which follows it. Transfusion is therefore indicated more for the acute anæmia after the hemorrhage has ceased and is not likely to be renewed. It should not be employed immediately after profuse hæmatemesis, unless it is probable that otherwise the patient will die from the loss of blood, and then it is well to transfuse only a small quantity.¹²¹

¹²¹ Michel transfused successfully in a case of extreme anæmia following gastrorrhagia (Berl. klin. Wochenschr., 1870, No. 49). In a case of profuse and repeated hæmatemesis which followed washing out the stomach Michaelis infused into the veins 350 cc. of solution of common salt. Reaction gradually followed, and the patient recovered. This case, which was one of probable ulcer, illustrates the advantages of infusing a small quantity (ibid., June 23, 1884). The dangers are illustrated by a case reported by V. Hacker, who infused 1500 cc. of salt solution in a patient in a state of extreme collapse resulting from hemorrhage from gastric ulcer. The patient rallied, but he died three hours after the infusion from renewed hemorrhage (Wiener med. Wochenschr., 1883, No. 37). In Légroux's case of gastric ulcer renewed hemorrhage and death followed the transfusion of only 80 grammes of blood (Arch. gén. de Méd., Nov., 1880). In a case quoted by Roussel, Leroy transfused 130 grammes of blood in a girl twenty years old who lay at the point of death from repeated hemorrhages from a gastric ulcer. In the following night occurred renewed hemorrhage and death (Gaz. des Hôp., Sept. 22, 1883). According to the experiments of Schwartz and V. Ott, the transfusion, or rather infusion, of physiological salt solution is as useful as that of blood, and it is simpler and unattended with some of the dangers of blood-transfusion. The formula is chloride of sodium 6 parts, distilled water 1000.

Schilling recommends, when the bleeding is so profuse that the patient's life is threatened, to tampon the stomach by means of a rubber balloon attached to the end of a soft-rubber stomach-tube.¹²² The external surface of the balloon is slightly oiled. It is introduced into the stomach in a collapsed state, and after its introduction it is moderately distended with air. When the balloon is to be withdrawn the air should be allowed slowly to escape. Schilling tried this procedure in one case of hemorrhage from gastric ulcer, allowing the inflated bag to remain in the stomach twelve minutes. The hemorrhage ceased and was not renewed. Experience only can determine whether this device, to which there are manifest objections, will prove a valuable addition to our meagre means of controlling hemorrhage from the stomach.

¹²² F. Schilling, Aerztl. Intelligenzbl., Jan. 8, 1884. Schreiber, in order to determine the position of the stomach, was the first to introduce and inflate in this organ a rubber balloon (Deutsches Arch. f. klin. Med., June 5, 1877). Uhler recommends in case of profuse gastric hemorrhage to pass a rubber bag into the stomach and fill it with liquid (Maryland Med. Journ., Aug. 30, 1884, p. 347).

The boldest suggestion ever made for stopping gastric hemorrhage is that of Rydygier, who advocates in case hemorrhage from an ulcer threatens to be fatal to cut down upon the stomach, search for the bleeding ulcer, and then resect it.¹²³ Notwithstanding the great advances made in gastric surgery during the last few years, Rydygier's suggestion seems extravagant and unwarrantable.

¹²³ Berl. klin. Wochenschr., Jan. 16, 1882.

The most effectual treatment of the dyspepsia which is present in many cases of gastric ulcer is adherence to the dietetic rules which have been laid down, aided by the administration of Carlsbad salts and perhaps in extreme cases the occasional and cautious use of the stomach-tube. If eructations of gas and heartburn are troublesome, antacids may be employed, but they should be given in small doses and not frequently, as the ultimate effect of alkalies is to increase the acid secretion of the stomach and to impair digestion. The best alkali to use is bicarbonate of sodium, of which a few grains may be taken dry upon the tongue or dissolved in a little water.

If perforation into the peritoneal cavity occur, then opium or hypodermic injections of morphine should be given in large doses, as in peritonitis. Bran poultices sprinkled with laudanum or other warm fomentations should be applied over the abdomen, although in Germany ice-bags are preferred. Food should be administered only by the rectum. The chances of recovery are extremely slight, but the patient's sufferings are thus relieved. In view of the almost certainly fatal prognosis of perforation of gastric ulcer into the general peritoneal cavity, and in view of the success attending various operations requiring laparotomy, it would seem justifiable in these cases, after arousing, if possible, the patient from collapse by the administration of stimulants per rectum or hypodermically, to open the peritoneal cavity and cleanse it with some tepid antiseptic solution, and then to treat the perforation in the stomach and the case generally according to established surgical methods.¹²⁴ This would be the more indicated if it is known that the contents of the stomach at the time of perforation are not of a bland nature.

¹²⁴ Mikulicz has successfully treated by laparotomy a case of purulent peritonitis resulting from perforation of the intestine with extravasation of the intestinal contents. He says that the operation is not contraindicated by existing peritonitis if the patient is not already in a state of collapse or sepsis. The perforation is closed by sutures after freshening the edges of the opening (abstract in the Medical News, Philada., Sept. 6, 1884). Both Kuh and Rydygier recommend opening the abdomen after perforation of gastric ulcer. The borders of the ulcer are to be resected and the opening closed by sutures (Volkmann's Samml. klin. Vorträge, No. 220, p. 12).

It is important to maintain and to improve the patient's nutrition, which often becomes greatly impaired from the effects of the ulcer. This indication is not altogether compatible with the all-important one of reducing to a minimum the digestive work of the stomach. Nevertheless, some of the easily-digested articles of food which have been mentioned are highly nutritious. By means of these and by good hygienic management the physician should endeavor, without violating the dietetic laws which have been laid down, to increase, so far as possible, the strength of his patient. Starvation treatment in itself is never indicated in gastric ulcer. Inunction of the body with oil is useful in cases of gastric ulcer, as recommended by Pepper.¹²⁵

In view of Daettwyler's experiments, mentioned on page [514], it is manifestly important to counteract the anæmia of gastric ulcer. Iron, however, administered by the mouth, disturbs the stomach and is decidedly contraindicated during the active stage of gastric ulcer. During convalescence, only the blandest preparations of iron should be given, and these not too soon, lest they cause a relapse. When the indication to remove the anæmia is urgent, and especially when the chlorotic form of anæmia exists, it may be well to try the hypodermic method of administering iron, although this method has not yet been made thoroughly satisfactory. Especially for the anæmia of gastric ulcer would an efficient and unirritating preparation of iron for hypodermic administration prove a great boon. Probably at present the best preparation for hypodermic use is the citrate of iron, given in one- to two-grain doses in a 10 per cent. aqueous solution, which when used must be clear and not over a month old. The syringe and needle shortly before using should be washed with carbolic acid. The injections are best borne when made into the long muscles of the back or into the nates, as recommended by Lewin for injections of corrosive sublimate. A slight burning pain is felt for ten minutes after the injection. This is the method employed by Quincke with good result and without inflammatory reaction.¹²⁶ It is well to remember that Kobert¹²⁷ has found by experiment on animals that large doses of iron injected subcutaneously cause nephritis. Other preparations of iron which have been recommended for hypodermic use are ferrum dialysatum (DaCosta), ferrum pyrophosphoricum cum natr. citrico (Neuss), ferrum pyrophosphoricum cum ammon. citr. (Huguenin), ferrum peptonatum and ferrum oleinicum (Rosenthal).¹²⁸ When it becomes safe to administer iron by the stomach, then the blander preparations should be used, such as the pyrophosphate, lactate, effervescing citrate, ferrum redactum. Leube recommends the following prescription: Ferr. redact. gr. 80, Pulv. althææ gr. 60, Gelatin q. s.; make 90 pills: at first one, and afterward as many as three, of these pills may be taken three times a day. When carefully prepared the pills are about as soft as butter.

Various sequels of gastric ulcer may require treatment. Cicatrization of the ulcer is by no means always cure in the clinical sense. As the result of adhesions and the formation and contraction of cicatricial tissue very serious disturbances of the functions of the stomach may follow the repair of gastric ulcer. The most important of these sequels is stenosis of the orifices of the stomach, particularly of the pyloric orifice. Very considerable stenosis of the pylorus may be produced before the ulcer is completely cicatrized. In three instances a stenosing ulcer of the pylorus has been successfully extirpated.¹²⁹ The most important of these sequels of gastric ulcer will be treated of hereafter. Here it need only be said that during convalescence from gastric ulcer attention to diet is all-important. For a long time the diet should be restricted to easily-digested food. The first symptoms of relapse are to be met by prompt return to bland diet, or, if necessary, to rectal alimentation.

¹²⁹ The successful operators were Rydygier (Berl. klin. Wochenschr., Jan. 16, 1882), Czerny (Arch. f. klin. Chir., Bd. xxx. p. 1), and Van Kleef (Virchow u. Hirsch's Jahresbericht, 1882, Bd. ii. p. 383). Cavazzani cut out by an elliptical incision an old indurated ulcer of the stomach adherent to the anterior abdominal walls. The patient died three years afterward of phthisis (Centralbl. f. Chir., 1879, p. 711). Lauenstein resected the pylorus unsuccessfully for what appears to have been an ulcer of the pylorus with fibroid induration around it (ibid., 1882, No. 9). These four cases (three successful) are all which I have found recorded of resection of gastric ulcer. In my opinion the resection of gastric ulcers which resist all other methods of treatment, and especially those which cause progressive stricture of the pylorus, is a justifiable operation.

Addendum.

Ulcers of the stomach which do not belong to the category of simple ulcer are for the most part of pathological rather than of clinical interest.

Although miliary tubercles in the walls of the stomach are more frequent than is generally supposed, genuine tuberculous ulcers of the stomach are not common. The most important criterion of these ulcers is the presence of tuberculous lymphatic glands in the neighborhood, and of miliary tubercles upon the peritoneum corresponding to the ulcer. Sometimes miliary tubercles can be discovered in the floor and sides of the ulcer. Tuberculous gastric ulcers, when they occur, are usually associated with tuberculous ulceration of the intestine. In an undoubted case of tuberculous ulcer of the stomach reported by Litten, however, this was the only ulcer to be found in the digestive tract.¹³⁰ Tuberculous gastric ulcers generally produce no symptoms, but they have been known to cause perforation of the stomach and hæmatemesis. Many cases which have been recorded as tuberculous ulcers of the stomach were in reality simple ulcers. Cheesy tubercles as large as a pea, both ulcerated and non-ulcerated, have been found in the stomach, but they are very rare.

¹³⁰ Litten, Virchow's Archiv, Bd. 67, p. 615.

Typhoid ulcers may also occur in the stomach, but they are infrequent. Both perforation of the stomach and gastrorrhagia have been caused by typhoid ulcers, which, as a rule, however, produce no symptoms distinctly referable to the ulcer.

Syphilitic ulcers and syphilitic cicatrices of the stomach have been described, without sufficient proof as to their being syphilitic in origin.

Necrotic ulcers, probably mycotic in origin, may be found in the stomach in cases of splenic fever, erysipelas, pyæmia, etc.

Ulceration occurring in toxic, in diphtheritic, and in phlegmonous gastritis need not be discussed here.

Follicular and catarrhal ulcers of the stomach have been described, but without sufficient ground for separating them from hemorrhagic erosion on the one hand and simple ulcer on the other.

Hemorrhagic erosions of the stomach, to which formerly so much importance was attached, are now believed to be without clinical significance. They are found very frequently, and often very abundantly, after death from a great variety of causes.
