Abstract
The cases of one hundred civilian patients with gunshot wounds of the colon treated at the Louisville General Hospital have been reviewed. Most injuries were in the transverse colon (44 per cent), followed by the ascending colon (27 per cent), rectosigmoid (19 per cent), and descending colon (10 per cent). Associated injuries occurred in 81 per cent of the patients; the small bowel was the most common structure injured. Primary closure was used in 52 per cent of the patients, with a resultant 19 per cent rate of wound infection and 14 per cent rate of serious complication. When the extent of contamination or tissue destruction required resection, an attempted primary anastomosis was followed by a high rate of wound infection (57 per cent) and serious complications (36 per cent) as compared with end-colostomy and mucous fistula, which resulted in a 24 per cent rate of wound infection and 24 per cent rate of serious complication. The rate of wound infection between these groups is significant (p = 0.05). Results with end-colostomy and mucous fistula were better than with attempted primary anastomosis. Primary closure of missile injuries of the colon is feasible but should not be attempted in the presence of gross fecal peritonitis or massive tissue destruction. If resection is undertaken, end-colostomy (or ileostomy) and distal mucous fistula should be performed in the presence of intra-abdominal contamination to reduce the incidence of postoperative wound infection and serious complications. Delayed primary closure should also reduce the rate of wound infection in these patients.
