Anal sphincter preservation in locally advanced low rectal adenocarcinoma after preoperative chemoradiation therapy and coloanal anastomosis

Abstract

In patients with locally advanced rectal cancer located 3-6 cm from anal verge who are traditionally treated with abdominoperineal resection, preservation of anal sphincter after preoperative chemoradiation therapy plus complete rectal excision with coloanal anastomosis is feasible and is associated with acceptable morbidity and no mortality.
