As a rule this is a late condition. In one case of injury to the ascending colon recounted above, however, considerable local escape of fæces had occurred, and a successful result was obtained by a local incision on the third day without suture of the bowel. In this case I believe the wound in the bowel to have been of the nature of a long slit, but the surrounding adhesions were so firm as to render any interference with them a great risk, and a successful result was obtained at the cost of a somewhat prolonged recovery. I am convinced that the best course was followed here. (No. 131.)

When the suppuration was of a less acute character, it was generally advisable to allow the pus to make its way towards the surface before interference.

5. Cases of injury to the colon in which the posterior aspect is involved should be treated by free opening up of the wound, and either by suture of the bowel or else its fixation to the surface. I operated on one such case, and although the patient eventually died on the eighth day, from septicæmia, he certainly had a chance. Two cases where the opening looked so free that one almost thought the wound could be regarded as a lumbar colotomy did badly; in both infection of the pleura took place, besides extension of suppuration into the retro-peritoneal areolar tissue. In the future I should always feel inclined to enlarge such wounds and bring the bowel to the surface.

As regards actual technique the majority of the wounds are particularly well suited to suture; three stitches across the opening and one at either end of the resulting crease sufficed to close the opening effectively. The openings in the small intestine were not as a rule difficult to find, on account of the ecchymosis which surrounded them. From what I have seen stated in the reports given by other surgeons, there seems to have been more difficulty in discovering wounds in the large gut. Under ordinary circumstances the only instruments specially needed are a needle and some silk. At my first two operations, as my instruments had gone astray, the wounds were readily closed by a needle and cotton borrowed from the wife of a railway porter.

If aseptic sponges or pads are not available, boiled squares of ordinary lint may be employed for the belly, and towels wrung out of 1 to 20 carbolic acid solution used to surround the field of operation. Whenever there is any likelihood of the necessity for operations, water boiled and filtered should be kept ready in special bottles.

When septic peritonitis was already present, the ordinary procedure of dry mopping, followed by irrigation, was necessary, before closing the belly.

The after-treatment should be on the usual lines as to feeding, &c.

I am unaware to what degree success followed intestinal operations generally during the campaign. I saw only one case in which the small intestine had been treated by excision and the insertion of a Murphy's button in which a cure followed: this case was in the Scottish Royal Red Cross hospital under the care of Mr. Luke. I heard of two cases in which the large intestine was successfully sutured, and of one other in which recovery followed the removal of a considerable length of the small bowel for multiple wounds.

In concluding these most unsatisfactory remarks, I should add that the impressions are those that were gained as the result of the conditions by which we were bound in South Africa, and which might recur even in a more civilised region. Under really satisfactory conditions nothing I saw in my South African experience would lead me to recommend any deviation from the ordinary rules of modern surgery, except in so far as I should be more readily inclined to believe that wounds in certain positions already indicated might occur without perforation of the bowel when produced by bullets of small calibre; and further in cases where I believed the fixed portion of the large bowel was the segment of the alimentary canal that had been exposed to risk, I should not be inclined to operate hastily.

A careful consideration of the whole of the cases that I saw leaves me with the firm impression that perforating wounds of the small intestine differ in no way in their results and consequences when produced by small-calibre bullets, from those of every-day experience, although when there is reason merely to suspect their presence an exploration is not indicated under circumstances that may add a fresh danger to the patient.
