Twenty-four patients with rectal villous adenomas were operated on which posterior transphincteric approach. They had benign villous adenona in (13 patients), villous adenomas showing atypia (2), and villous adenomas developed malignancy (9). All the patients gained excellent results, except one with wounded infection after operation. No patient died at operation. No patient developed rectal fistula and incontinence of feces. The different methods of operation with excised villous adenoma of the rectum were discussed and compared. We conclude that the posterior transsphincteric approach is better than others.
