Excision of the rectum with colonic J pouch-anal anastomosis for adenocarcinoma of the low and mid rectum.

Abstract

The results of rectal excision with colonic pouch-anal anastomosis are reviewed from a series of 162 patients covering 7 years. All patients have been operated upon in the same institution and consecutively. The follow-up is now sufficient to allow an accurate evaluation of the outcome of the patients. The main goal of this study was to provide a detailed report of the functional results. Continence was satisfactory in 96% of the patients, with either a perfect continence or minor troubles that would not have been detectable other than by a rigorous questioning. The mean number of bowel movements was 2 per 24 hours. Fragmentation of the defecation and urgency were absent. Twenty-five per cent of the patients had to elicit the evacuation of the reservoir with a suppository or an enema. Improvement of function yielded by a reservoir over straight colo-anal and low colo-rectal anastomoses are significant and, as suggested by manometric studies, are directly related to the restoration of a reservoir function.
