The management of colon injuries by primary repair or colostomy.

This retrospective study comprises 134 cases of penetrating colon injuries. In 92 cases the injury involved the left colon and in the remaining 42 the right colon. Death due to the colonic injury occurred in 1.5 per cent and the incidence of abdominal complications was 17.9 per cent. Patients treated by primary repair of the colon had less colon-related complications and a shorter hospital stay than patients treated by colostomy. Left and right colon injuries treated by primary repair had similar complication rates and hospital stay (P greater than 0.05). We believe that primary repair can safely be performed more frequently than is generally accepted. The site of colon injury, the presence of shock and the presence of multiple associated intra-abdominal injuries do not exclude primary repair. It is suggested that colostomy should be reserved for both left and right colon injuries with gross peritoneal contamination, extensive colonic damage, and large amount of hard faeces in the colon.
