The records of 115 patients with a duodenal injury have been reviewed. The majority of the patients (83 percent) were treated with primary repair of the injury. Twelve patients underwent duodenal diverticulization. The mortality rate in all 115 patients was 12 percent, in 105 patients who survived more than 48 hours 4 percent, and in 26 patients with pancreaticoduodenal injury 15 percent. Vascular injury was the major cause of early death. Enteric perforations were present in 75 percent of the patients with sepsis. The majority of patients with associated pancreatic injury had primary repair and did not have pancreaticoduodenal complications. Duodenal fistula continues to be a serious postoperative complication. Primary repair with drainage is the preferred treatment. Gastrostomy and feeding jejunostomy are useful adjuncts. A more complex operation should be reserved for a highly select group of patients with severe duodenal injury.
