A Treatise on Gunshot Wounds

by Sir T. Longmore

Gunshot wounds of the abdomen, like those of the chest, are, for the sake of convenience, divided into non-penetrating and penetrating. The NON-PENETRATING may be either simple flesh wounds, or may be accompanied with fracture of some of the pelvic bones, or with injury to some of the contained viscera. In PENETRATING wounds, the peritoneum only, or, together with it, one or more of the abdominal viscera, may be wounded; or, in comparatively rare cases, a viscus may be penetrated without the peritoneum being involved. It is in the regional cavity of the abdomen that the proportion of penetrating wounds is the greatest. The cranium, from its form, structure, and coverings, serves as a strong defense even against gunshot; the osseous yet elastic and movable ribs, the sternum, and muscular parietes greatly protect the contents of the cavity which they inclose; but the extensively exposed surface of the abdomen, anteriorly and laterally, has no power of resistance to offer against a projectile directly impinging it; and when this important cavity is once penetrated by these means, death is the almost inevitable result. Even the chances of a favorable termination which may exist in wounds from other causes are generally wanting; and much of their treatment, such as the use of sutures, and other means to insure the apposition of cut edges, is inapplicable, from the parts to a certain distance being almost necessarily deprived of their vitality, to injuries from gunshot.

Non-penetrating wounds require but few remarks in this place. The fatal injuries which occasionally occur from masses of shell or round shot, in which the liver, spleen, or other viscera are ruptured without penetration of parietes, and where death ensues from shock, hemorrhage, or peritonitis, have already been alluded to. If, although the viscera have been contused, the injury does not amount to being mortal, the patient should be subjected to perfect quiet, extreme abstinence, and, only when inflammation arises, to the necessary treatment for its control. If the parietes have been much contused, abscess or sloughing may be expected; and a tendency to visceral protrusion must be afterward guarded against.

When portions of the pelvic parietes are fractured by heavy projectiles, very protracted abscesses generally arise, connected with necrosed bone; and the vital powers of the patient are greatly tried by the necessary restraint and long confinement. The great force by which these wounds must be produced, and the general contusion of the surrounding structures, cause a large proportion sooner or later to prove fatal, notwithstanding the peritoneal cavity may have escaped. Of twenty-nine such cases which came under treatment in the Crimea, sixteen died. Even apparently slight cases, as where a portion of the crest of the ilium is carried away by shell, or ball lodged in one of the pelvic bones, often prove very tedious, from the long-continued exfoliations and abscesses which result.

Penetrating wounds.—A penetrating wound of the abdomen, whether viscera be wounded or not, is usually attended with a great amount of “shock.” The prognosis will be extremely unfavorable, if there is reason to fear the projectile has lodged in the cavity of the peritoneum; and in all cases the danger will be very great from inflammation of this serous investment. The liability to accumulation of blood in the cavity, from some vessel of the abdominal wall being involved in the wound, must not be forgotten.

When, in addition to the cavity being opened, viscera are penetrated, and death does not directly ensue from rupture of some of the larger arteries, the shock is not only very severe, but the collapse attending it is seldom recovered from up to the time of the fatal termination of the case. This is sometimes the only symptom which will enable the surgeon to diagnose that viscera are perforated. The mind remains clear; but the prostration, oppressive anxiety, and restlessness are intense; and, as peritonitis supervenes, pain, dyspnœa, diffused tenderness, irritability of the stomach, distention, and the other signs of this inflammation are superadded. In ordinary wounds from musket-shot, scarcely any matter will escape from the opening of the parietes, the margin of which becomes quickly tumefied; but if any escape, it will probably indicate what viscus has been wounded. If the stomach has been penetrated, there will probably be vomiting of blood from the first. If the spleen or liver be wounded, death from hemorrhage is likely to follow quickly. In some instances patients, however, recover after gunshot wounds involving these viscera, and examples in illustration may be found in various works on military surgery. Two particularly manifest instances, where officers were shot through the liver by musket-balls, occurred lately in India, one at Lucknow, the other at the siege of Delhi: both recovered. The cases are described in the Indian Annals of Medical Science for January, 1859. If the small intestines have been perforated, and death follows soon after from peritonitis, the bowels usually remain unmoved, so that no evidence is offered of the nature of the wound from evacuations; but in any case of penetrating wound of the abdomen, when the opportunity is offered, steps should be taken—a matter not unlikely to be omitted under the circumstances of camp hospitals full of patients—to isolate and examine all evacuations which may follow. By attending to this direction, the writer had the satisfaction of ascertaining the passage of a ball and piece of cloth, after a wound in the loin, in a case already alluded to. If the kidneys or bladder are penetrated, the escape of urine into the abdomen is almost a certain cause of fatal result. The latter viscus may, however, be penetrated without the peritoneal cavity being opened; and, as experience proves, the wound is then by no means of a fatal character. Musket-balls sometimes lodge in the bladder. This was ascertained to have happened in a soldier of the 20th Regiment, in the Crimea; but the patient died from other injuries, so that the information could not be turned to account. Mr. Guthrie performed the usual operation of lithotomy, with success, to remove a musket-ball which had struck a soldier just above the pubes, at Waterloo, and lodged. He also records a similarly successful case in a man wounded at the battle of Chillianwallah: this ball formed the nucleus of a calculus. Baron Percy removed a ball and a portion of shirt from the bladder. In all such cases, it is probable that the bladder has been penetrated at some part uncovered by peritoneum, so that the cavity of the abdomen has not been opened; or, if otherwise, the foreign body has found its way in by ulceration, after adhesions had been established, and thus circumscribed the openings of communication. Small foreign bodies may also pass into the bladder by the ureter. A case in which the kidney was wounded came under the care of the writer, after the 8th of September, 1855. The patient survived twelve days, and then died from pyemia. He had been taken prisoner, but was found in Sebastopol, and brought to his regimental hospital on the second day after the assault. There was only one wound in the right loin, and the ball had lodged. Extensive abscesses formed among the gluteal muscles on the left side, and down the left thigh; and though free incisions were made, great constitutional irritation supervened, and he sank. The substance of the right kidney had been perforated, but the ureter had escaped. The ball had passed across the abdomen, and lodged in the left buttock. Mr. Guthrie mentions some wounds of the kidney where recovery took place; in one, seven months after the wound, after an attack of retention of urine, a piece of cloth was forced out by the urethra, which must have come down from the pelvis of the kidney. When the abdominal parietes have been opened by shell or passage of large shot, protrusion of omentum and intestines will probably be one of the results. This does not always happen. In Dr. Macleod’s Notes, p. 237, is detailed a remarkable case of recovery, which was witnessed by the writer, after the wall of the abdomen, including the peritoneum, had been destroyed to the extent of five inches long by three broad; and a coil of intestine laid bare without protrusion, in the right iliac region. This patient had also a fracture of the ileum, another of the great trochanter on the same side, and his right forearm smashed. This case was treated in the general hospital before Sebastopol, by Mr. Hooke. Sometimes a wound caused by a large projectile, which was at first not penetrating, will indirectly become so, from the severe contusion and consequent sloughing to such an extent as to denude the viscera; and if, as is not unlikely, adhesion has taken place in the mean time between a portion of the viscera and peritoneal lining of the abdominal paries, the sloughing action may extend more deeply and the bowel itself become opened.

Curious instances are recorded in which balls have passed directly through the abdomen without perforating any important viscus, as proved by examination after death. As an example, on the other hand, of the number of wounds which may thus be inflicted, a soldier of the 19th Regiment, on duty in the trenches before Sebastopol, who was shot through the abdomen in the act of defecation, was found by the writer, on post-mortem examination, to have had as many as sixteen openings made in the small intestine. He survived the wound nineteen hours.

Gunshot wounds of the colon, especially of the sigmoid flexure, appear to be less fatal, probably from structural causes as well as circumstances of position, than wounds of the small intestine. In the Museum of Fort Pitt, however, is a preparation of jejunum exhibiting three constrictions, and supposed to have been perforated in three places, from a private of the 80th Regiment, who was shot through the abdomen at Ferozeshah, in 1845, and who died from cholera in 1851. Inspector-General Taylor, C.B., then surgeon of the regiment, who made the examination post mortem, thus described the injured part of the intestine: “The intestines neither there nor elsewhere were morbidly adherent; but the fold of intestines immediately opposed to the cicatrix presented a line of contraction as if a ligature had been tied round the gut. The same appearance existed in two other places.” It seems more likely that the gut was contused than perforated, and that contraction gradually supervened, especially as no adhesions were found; and, when wounded, the symptoms were so slight as to have led to the supposition that the ball had gone round the abdominal wall.

A gunshot wound of the intestine, more especially the colon, may lead to fecal fistula, and life be thus saved for a time. One such case only occurred in the Crimea, in the 19th Regiment, of which the writer was then the surgeon; this case, which has been before casually mentioned, subsequently passed under the care of his friend Mr. Birkett, of Guy’s Hospital, in which institution the patient died, from the effects of albuminuria, four years after the receipt of the wound referred to. The surgical history of this case has been already published at some length in the Lancet;[9] the medical history, together with the results of the post-mortem inspection, have been detailed by Dr. Habershon, in vol. v., Ser. III., of the Guy’s Hospital Reports. The fistula became closed at intervals, and occasionally, before other disease supervened, hopes were entertained that recovery might result. The direction and depth of the wound precluded any of the usual operations for attempting to effect a radical cure. Two cases of abnormal anus by gunshot perforation are recorded by Dr. Williamson among the wounded who have recently returned from India; in both instances the descending colon was the part of the bowel implicated. A similar result is recorded in a private of the 13th Regiment wounded at Cabul in 1840.

Wounds of the diaphragm.—Musket-balls occasionally pass through the diaphragm; and Mr. Guthrie has remarked that these wounds, in instances where the patients survive, only become closed under rare and particular circumstances. Hence the danger of portions of some of the viscera of the abdomen, as the stomach or colon, passing into the chest, and thus forming diaphragmatic herniæ, and of these, eventually, from some cause becoming strangulated. Two very interesting preparations of these accidents from gunshot exist in the museum at Fort Pitt. In both instances, the stomach, colon, and omentum form the hernial protrusions. In one, death occurred, a year after the wound, from strangulation induced suddenly after a full meal; in the other, the soldier continued at duty twenty-two years after, and died from other causes. All the cases which occurred in the Crimea in which openings had thus been established between the cavities of the chest and abdomen proved fatal. A case is detailed in the Surgical History of the War where the patient survived a double perforation of the diaphragm, together with a wound of the liver, six days; in another instance, where the lung, diaphragm, liver, and spleen were wounded, the soldier lived sixteen hours. The direction of the ball, hiccough, dyspnœa accompanied with spasmodic inspiration, and inflammatory signs more particularly connected with the chest will be the usual indications of such a wound; and in case of recovery, the risk of hernial protrusion and strangulation must be explained to the patient. Should strangulation occur, it can hardly be expected that division of the stricture could be performed without the operation itself leading to equally certain fatal results.
