Transanal excision of rectal villous adenomas by laparoscopic methods

Large villous adenomas of the rectum are not uncommon and will be encountered often by general and colorectal surgeons in their practices. The approach to large adenomas can be via the colonoscope either transabdominally or transanally. A simple transanal method was instituted by the author in 1992 and has been used up to the time of writing. This involves using a 4-cm diameter transanal operating rectoscope with laparoscopic instruments and the laparoscope itself. The results for 13 patients from January 1992 to April 2001 are reviewed. The method is simple and allows access to lesions up to 15 cm from the anal verge with a low incidence of complications, residual disease, and recurrence.
