[Replacement function of the ileum in resections of the colon and rectum].
Use of ileal segments to re-establish intestinal continuity after colorectal resection is a well-established method but indications are rare. Rectal lesions are nowadays treated more and more often by anterior resection or "pull-through" methods are increasingly common and have benefited from improvement of anastomotic techniques and use of mechanical suture devices. Ten years ago rectal lesions were still treated by abdominoperineal resection. During colorectal resection, with or without evagination, ischemic complications of the colon may compromise preservation of the sphincteral apparatus. In this case it is impossible to avoid colostomy by substitution of an ileal segment for the colon. Treatment can involve surgical restoration of the colon, ileum and rectum or of the colon, ileum and anus. The different operative steps are analyzed. The functional results were the same as those seen with transanal lowering of the colon with evagination.
