Rectal sphincter reconstruction in perineal colostomies after abdominoperineal resection for cancer.

Abstract

A surgical technique is proposed for the reconstruction of the anal sphincter in perineal colostomies after abdominoperineal resection for cancer. The procedure, which employs the gracilis muscle for the sphincteric reconstruction is described and the operative results and complications are analysed in 24 patients submitted to this type of surgery. Of the 22 patients who were followed up, 17 had excellent or good results with retention of solid or soft stools. Three patients had poor results with no voluntary retention, while 2 others were partly incontinent of solid faeces. In this group of 5 patients, 3 had stenosis of the colostomy and 1 had no sensibility of impending defaecation.
