Prospective study of the effect of resection of the rectum on male sexual function

Abstract

A prospective study to evaluate sexual dysfunction following resection of the rectum was performed in 21 male patients. Following proctocolectomy for inflammatory bowel disease (9 patients), the incidence of sexual dysfunction was 11%, and it was always partial. Following abdominoperineal excision of the rectum for carcinoma (7 patients), the incidence of sexual dysfunction was 50%, and it was total in 16%. After anterior resection with low colorectal anastomosis (5 patients), the incidence of sexual dysfunction was 40%. The risk of dysfunction following operations on the rectum increased with the age of the patient and was minimal below the age of 50 years. In patients with inflammatory bowel disease, careful dissection close to the rectum should avoid damage to the pelvic nerves, and the incidence of sexual dysfunction should be low.
