Intestinal anastomoses after radiation therapy by surgical stapling instruments

The use of automated stapling instruments in 17 patients requiring intestinal surgery following irradiation therapy for gynecologic malignancies has been reviewed. Fifteen of these patients also had other medical problems thought to inhibit optimal anastomotic healing: malnutrition, persistent intraabdominal cancer, uremia, hypoalbuminemia, and recent antineoplastic chemotherapy. Although these conditions severely test a method of intestinal anastomosis, no patient had a complication involving the intestinal anastomosis. The use of these stapling instruments reduced both the operating time and the contamination of the peritoneal surfaces by bowel content, thereby improving the postoperative recovery of these patients. The favorable results and the secure anastomoses justify the continued use of stapling instruments in gynecologic oncology patients with prior irradiation therapy.
