2. Cases brought into the Field, or even the Stationary hospitals, with symptoms of moderate severity, or even of an insignificant character, in which evidence of septic peritonitis suddenly developed and death ensued.
3. Cases in which the position of the wounds raised the possibility of injury to the intestine, but in which the symptoms were slight or of moderate severity, and which recovered spontaneously.
The whole crux in diagnosis lay in the attempt to separate the two latter classes, and, personally, I must own to having been no nearer a position of being able to form an opinion on this point, in the late than in the early stage of my stay in South Africa. The advent of peritoneal septicæmia was in many instances the only determining moment. On this matter I can only add that, in civil practice, an exploratory abdominal section is often the only means of determination of a rupture of the bowel wall.
With regard to the cases of suspected injury to the bowel which recovered spontaneously, the symptoms were somewhat special in their comparative slightness, and in the limited nature of the local signs. Thus the pulse seldom rose to as much as 100 in rate, 80 was a common average. Respiration was never greatly quickened, 24 was a common rate. The temperature rarely exceeded 100°. Vomiting was occasionally severe, but usually not persistent, ceasing on the second day. A good quantity of urine was passed. As to the local signs, these again were of a limited nature; distension did not occur, or was slight; movement of the abdominal wall was only restricted in the neighbourhood of the wound, the affected area amounted to a quarter, or at most half, the abdominal wall, and rigidity was localised to a similar segment. Local tenderness usually existed; but, as a rule, there was little or no dulness to point to the occurrence either of fluid effusion or a considerable deposition of lymph.
Again many of the patients suffered with very slight symptoms of constitutional shock, although there was considerable variation in this particular.
(165*) Wounded at Graspan, sustaining a compound fracture of the fibula. While being carried off the field, a second bullet (Lee-Metford) entered immediately outside the left posterior superior iliac spine, perforated the pelvis, and emerged 1½ inch within the left anterior superior spine. The patient was then put down and left on the field ten hours; later he was carried to shelter for the night, and arrived at Orange River on the second day. He suffered with some pain in the abdomen, especially during the journey in the train, but was not sick; the bowels were confined.
When seen on the third day at 6 p.m., some pain was complained of in the abdomen, which moved freely in the upper part, but was motionless below the umbilicus. No distension. Tenderness around wound of exit and some rigidity. The bowels had acted four times during the day; motions loose, dark brown, and containing no blood. Face not anxious, eyes bright, temperature 102°. Pulse 96, regular, and of good strength. Tongue moist and little furred.
The abdomen was opened at 5 a.m. on the fourth day, as the local signs had become more pronounced, and the patient had passed a restless night in great abdominal pain. A local incision was chosen, as the wound was presumably in the sigmoid flexure. The sigmoid flexure was adherent to the abdominal wall opposite the wound of exit, and a dark ecchymosed patch was found, but no perforation could be detected. Foul pus and gas escaped freely from the pelvis, but no wound of the large bowel could be discovered here. On enlarging the incision upwards three openings were found in a coil of jejunum, probably that about five feet from the duodenal junction usually provided with the longest mesentery. No fourth opening could be found. The openings were circular, about 1/3 inch in diameter, clean cut, with a ring of everted mucous membrane, and the wall of the bowel in the neighbourhood was thickened. All three openings were included within a length of 2½ inches. There was no surrounding ecchymosis of the bowel wall. Very little escaped intestinal contents were found in the situation of the bowel. The latter had apparently been retracted upwards, and lay to the left of the lumbar spine. The wounds were readily closed by five Lembert's sutures, three crossing the openings, and one at each end. The belly was then washed out with boiled water and closed. The delay in finding the wounds due to the mistaken impression that they would be found in the pelvis materially prolonged the operation, which lasted an hour and a half. The patient never rallied, and died seventeen hours later. It is possible that a wound in the sigmoid flexure was present which had already closed at the time of operation.
(166*) Wounded at Magersfontein. Entry (Mauser), opposite central point of left ilium; exit, 1½ inch above the centre of the right Poupart's ligament. Vomiting commenced soon after the injury, and this was continuous until the patient's arrival in the Stationary hospital on the fourth day, when the condition was as follows:—
Face extremely anxious in expression. Temperature 101°, sweating freely. Pulse 110, fair strength. Tongue moist. Abdomen much distended, rigid, motionless, tympanitic throughout. Bowels confined. No urine had been passed for twenty-four hours, ℥ij in bladder on catheterisation, clear, and containing no blood.
