The current abdominoperineal resection: oncological problems and surgical modifications for low rectal cancer

Abdominoperineal resection is the one of the oldest surgical procedures for rectal cancer. Outcome after abdominoperineal resection for rectal carcinoma is not as good as anterior resection as the risk of local recurrence is higher and survival is poorer. During abdominoperineal resection, the rate of rectal perforation is high and the circumferential margin is often involved. Recently the concept of cylindrical abdominoperineal resection has been reintroduced. It allows a large excision and the initial results are encouraging. The purpose of this article was to analyse the oncological results of abdominoperineal resection and to develop the potential technical modifications of the procedure.
