Elements of Surgery

by Robert Liston

The oblique inguinal, when recent and small, is termed Bubonocele; but when large, it generally descends into the scrotum—oscheocele—of course exterior to the tunica vaginalis; and in females into the labium. The tumour often attains an immense size, from continued application of the causes that produced it,—laborious occupations, or straining of muscles in any way. When of long duration, and not attended to, it is not uncommon for the swelling to hang as low as the middle of the thigh, or even down to the knee. In such cases, the testicles often are wasted, and the penis concealed; indeed the skin of the penis, as well as of the lower part of the abdomen, is stretched over the tumour. Crural or femoral hernia is, on the contrary, seldom larger than a small apple. Sometimes, but very rarely, the tumour is of large dimensions. I have seen one containing the transverse arch of the colon, the omentum, and a yard and a half of small intestine. The tumour is represented some pages further on.

When a very large hernia remains always full, the cavity of the abdomen diminishes in size; in fact, it adapts itself to its contents; and this must be kept in mind when interfering with such cases.

Inguinal hernia most frequently occurs in males, the femoral in females; and the reason of this is obvious on comparing the size of the inguinal and crural openings in the sexes. In the male, the inguinal opening is much larger than the femoral; in the female, the femoral is the larger,—the inguinal is small, containing only the round ligament of the uterus. The causes of hernia act equally on both openings, and therefore it is to be expected that protrusion will take place where there is the least resistance, where the parietes are most deficient.

Hernia can seldom be mistaken for any other swelling, by one at all acquainted with his profession, and who makes his examination attentively. The history, and the mode of its appearance, are to be attended to. The swelling proceeds from above—at times it recedes on the patient lying on his back and making pressure on the swelling—a distinct impulse is communicated to it on exertion of the abdominal muscles, as in coughing—the tumour is generally elastic, and its neck can be felt extending from the lower abdominal aperture. Also, the two kinds, inguinal and crural, can scarcely be confounded with each other; the former is above, the latter below, the ligament of Poupart. It will be proper, however, to enumerate shortly the diseases for which hernia may be mistaken.

Cirsocele may be confounded with inguinal hernia. Cirsocele, being a varix of the spermatic veins, enlarges on coughing and during the erect posture, like hernia; but in general the composition of the tumour can be ascertained by the feel which it imparts when handled,—the veins feel like a handful of earth-worms. Besides, the swelling is made to disappear, on emptying the dilated veins by pressure upwards; and, if the surgeon then firmly compress the inguinal aperture, the tumour will rapidly reappear, on account of the venous flow being interrupted, particularly if the patient exert his abdominal muscles, or assume the erect posture. Whereas, had hernia existed, the swelling could not have been reproduced; and, on the patient being directed to cough, a distinct impulse would have been felt with the finger. Hydrocele of the tunica vaginalis may be confounded with scrotal hernia, if its distinctive characters be not understood or attended to. The pyramidal swelling presents an equal surface, fluctuates, and is generally diaphanous; its formation is gradual, commencing at the lower part, and slowly ascending; the testicle cannot be readily felt at the bottom of the scrotum; there is no swelling at the inguinal canal, and the chord is felt free; the tumour is not affected by the position, motion, or exertions of the patient. These circumstances plainly indicate the nature of the case. Bubo, sarcocele, and acute swelling of the testicle, are sufficiently distinguished from hernia by their situation, form, feel, and history, and cannot be confounded with it save by the profoundly ignorant. Hydrocele of the spermatic chord is more likely to lead to deception when large; but it is generally small and circumscribed, involving the middle of the chord, leaving the inguinal aperture free, and the upper part of the spermatic chord distinct. Besides, whatever may be its size, its formation is always slow and indolent,—it is never capable of being pushed into the abdomen, and it is unaffected by those circumstances which contribute to mark hernia. But hydrocele of the chord and hernia may coexist, as in the following instance:—A gentleman had swelling in the course of the spermatic chord for many years, while in a warm climate. Bandages were applied, and great pain thereby occasioned. After his return to this country, pain in the belly and vomiting seized him on a Monday morning, and continued with more or less violence till the Sunday following. Then the vomiting became feculent, the belly excruciatingly painful and tender, the tumour tense, and the pulse weak. A physician opposed operative measures, having been convinced that his former complaint was a hydrocele of the chord. But I conceived that the symptoms warranted cutting down on the parts, and did so. A hernia was found containing omentum and a fold of bowel; a hydrocele of the chord lay alongside of it.

Crural hernia has been mistaken for bubo, and vice versâ. Lumbar abscess and varix of the femoral vein are also supposed to resemble it in some measure. The situation and form of the tumour in lumbar abscess is very different from those of hernia; and the mode of examination recommended in regard to cirsocele is equally applicable to the detection of dilated femoral vein. The distinctions between crural hernia and bubo are too obvious to require mention.

Patients with unreduced hernia are constantly in great danger; as bruising of the swelling, or accumulation of feces in the protruded bowel, are likely to occasion very unpleasant consequences. They are generally troubled with indigestion, flatulence, and constipation; a slight degree of constriction at the neck of the tumour produces an obstruction to the intestinal contents; the viscera in the sac have not due support and pressure, hence accumulations take place in them, and may be productive of serious and even fatal effects. No protrusion, in which these circumstances are likely to occur, should be allowed to exist, if possible. So afraid were the ancients of allowing hernia to remain unreduced, that it was their custom to cut all patients labouring under rupture who would submit to the operation; and this was generally performed by itinerant quacks. They returned the protrusion without opening the sac, and then the neck of the tumour was either stitched up, or tied along with or without the spermatic chord. The actual cautery, and the most powerful caustics, were also applied to the parts by some, and dreadful were the effects; yet after the neck of the sac had been destroyed, and perhaps the bone exposed and exfoliated, protrusion again took place by the side of the cicatrix. By many, castration was considered necessary for the cure of scrotal hernia. Such harsh measures were founded on erroneous and imperfect ideas of the nature of the disease, which are not often to be met with in the present day. Operations for unincarcerated hernia are not justifiable, and those who have operated in such circumstances give a very unfavourable account of the experiment.

The external applications employed to reduce hernia are various. Some are supposed to produce corrugation of the integuments, and contraction of the cremaster muscle, and thereby to force up the protruded intestine; others are of an astringent character, and their administrator may gravely believe and say, that by them he expects to tan the living scrotum, to reduce the hernia, and to present an insuperable obstacle to its reproduction. But all such means are visionary, and practically ineffectual; no external or internal remedy can attenuate and reduce the hernial sac, remove adhesion, or produce contraction of the tendinous and rigid apertures.

Herniæ are either reducible or irreducible. A hernia is said to be reducible, when the protruded bowel or viscus readily returns into the abdomen on the application of pressure to the swelling, or on the patient assuming the recumbent posture. When recent, the swelling may not be made to disappear without considerable difficulty; but, after the disease has become of long duration, the aperture through which the protrusion has taken place dilates and is relaxed, and admits of the ready passage of the hernial contents: such tumours are usually of considerable size. But reducible herniæ should not be permitted to enlarge, since their protrusion can be prevented by simple and safe means; after reduction, a properly fitted bandage, termed a Truss, is applied over the aperture and canal, and by the compression thus made the opening is rendered impervious to the abdominal viscera. In inguinal hernia, the pad of the truss must make equable compression over the whole of the canal; in the other species, the aperture is less extensive, and the pressure more direct. Perseverance in the use of a well-adapted truss is highly necessary in children from the first, so that a chance may be afforded of permanent cure by contraction of the opening and development of the surrounding parts. In young persons the canal is short, and almost direct, and from its becoming oblique and elongated during growth, prevention of protrusion may be effected. Descent must never be allowed during such attempts at cure. But in adults such a fortunate result can scarcely be expected; the truss must be constantly worn during the day—in bed it may be disused—and the patient must rest satisfied with thereby escaping those dangers to which protrusion of the hernia would render him always liable. Great care should be taken to ascertain in the morning, before the truss is applied, that no protrusion exists. If the opening be not much dilated, it may contract even in adults when protrusion is sedulously prevented. The patient will also require to avoid the causes of hernia. If he is subject to cough, or labours under bad urinary disease, by which the abdominal muscles are called frequently and fully into action, there is no chance of a cure; nothing but the continued use of a truss will afford safety.

Hernia is rendered irreducible, 1. By the formation of adhesions between the sac and the included parts. 2. By induration of the protruded omentum, and by accumulation of fat in it, or in the appendiculæ of protruded large intestine. 3. By contraction of the abdominal cavity from long-continued displacement of a large portion of its contents. 4. By the nature and connexions of the protruded part, as in hernia of the sigmoid flexure, or of the caput cœcum coli. 5. By firm compression of the abdomen. 6. By the tightness of the opening giving rise to engorgement of the protruded parts. 7. By accumulation of feces, solid or fluid, in the protruded portion of bowel. With care, some of these causes may be got over, and the tumour reduced. In irreducible hernia the use of a bag truss is indispensable to prevent increase of the protrusion. In irreducible femoral hernia of small size, a hollow pad with a weak spring is used with advantage, to give support to the contained parts, prevent farther protrusion, and guard the tumour against external violence. The patient must avoid violent exertion, keep his bowels open, and be careful of his diet; he is always in danger, and should know it. Many have lost their lives from blows otherwise not dangerous; and even straining at stool is sufficient to force additional portions of viscera into the neck of the sac, and thereby induce most serious distress. Ruptures often come down during an attack of bowel complaint, or after a dose of purgative medicine.
