[Usefulness of a colonic reservoir after resection of the rectum].

Resection of the rectum followed by low colo-rectal anastomosis or colo-anal anastomosis may result in functional modifications. A brief retrospective study of 210 cases showed that the considerable alterations (urgency, frequent stools) are essentially due to very low colo-rectal, supra-anal anastomoses. It would therefore be interesting to evaluate the result of colo-anal anastomoses with colonic reservoir in this group of patients.
