Is anterior resection of the rectosigmoid safe after preoperative radiation?
Forty patients with carcinoma of the rectum or rectosigmoid underwent preoperative irradiation, followed by anterior resection with anastomosis. The radiation dose was 4500 rads administered in 25 fractions over a period of five weeks. One to three weeks after the radiation was completed, anterior resection of the rectosigmoid with anastomosis was done. Of the 40 patients, 23 had hand-sewn anastomoses and 17 had EEA stapled anastomoses. Fourteen of the 40 had diverting loop colostomies, all colostomies were subsequently closed, and there were no clinical postoperative anastomotic leaks. Anterior resection and anastomosis are considered to be technically safe with the surgical and radiation techniques used.
