Penetrating colon trauma

Of 56 patients with penetrating colon injuries over 6 years, 15% underwent exteriorized repair, 21% received a colostomy, and 64% were treated with primary repair. Of the eight exteriorized repairs, four required conversion to colostomies. In the entire group of 12 colostomies, there were two deaths, four abscesses, and one empyema. Thirty-six patients (64%) underwent primary repair. In this group there was one superficial wound infection, one empyema, but no intra-abdominal abscesses. Eighty per cent had associated injuries. All laparotomy incisions in the primary repair group except two were closed primarily. Large amounts of saline irrigant were used in all cases. All patients received broad spectrum antibiotics pre- and postoperatively. Primary repair of colon injuries can be done safely in many cases. Proper attention must be given to the associated injuries, the patient's general condition, and the time interval between injury and repair. We now find few indications for exteriorization of injured colons. Colostomies are done if our criteria for safe primary repair are not fulfilled.
