Thirty-four cases of duodenal trauma, 23 caused by gunshot wounds, are reviewed. All but three patients had associated major organ injuries, a total of 97 injuries. Postoperative mortality was 14% for injuries into the duodenal lumen. Techniques for operative repair included simple primary closure, use of omental or serosal patches, controlled fistula with a duodenostomy tube, decompressive and feeding ostomies, “diverticulization,” segmental duodenal resection and anastomosis, and total duodenectomy and pancreatectomy. It is emphasized that the surgeon finding duodenal injury must be familiar with all of these techniques, each of which has its indications. Treatment of duodenal injuries perhaps more than any other bowel trauma must be individualized.
