Radical surgical approach to radiation injury of the small bowel

During a period of 12 years, 52 patients without tumor recurrence were treated for chronic radiation injury to the small bowel. Eighteen patients also had concomitant large bowel injuries. Forty-seven patients were treated surgically, 42 of whom presented with obstruction, necrosis, or perforation of the bowel and had emergency operations. Thirty-eight patients underwent wide resection of the injured bowel, and six had bypass procedures. Anastomotic leakage occurred in 6 percent of the patients. The operative morbidity rate was 34 percent, and the mortality rate, 9 percent. Based on this experience, when surgery for small intestinal radiation injury is mandatory, the procedure should be a generous small bowel resection whenever possible, and probably should be performed only by experienced surgeons.
