Use of the posterior surgical approach for the management of villous adenoma of the rectum below the peritoneal reflection has been evaluated in eleven patients. There has been no mortality and no recurrence. The Kraske approach was also suitable in four patients with noninvasive adenocarcinoma arising within villous adenomas, although there is no place for this procedure in the treatment of invasive carcinoma.
