Sphincter repair without overlapping for fecal incontinence.

Abstract

Forty patients who had sphincter repair by one surgeon over the last 15 years were reviewed. The etiology of sphincter trauma was previous surgery (22), childbirth (14), and accidental trauma (4). Eleven patients had undergone at least one previous attempt at repair. Prior to operation, 12 patients were incontinent for liquid stool and 28 for formed stool. A technique of sphincter repair without overlapping was used. An associated diverting colostomy was carried out on seven patients who had had a previous failed repair. Follow-up was an average of 17 months after operation (range, 2-96 months). After operation, 25 patients were completely continent, 6 had occasional leaks of liquid stool, 4 were continent for solid stool only, and 5 showed no improvement. Neither diverting colostomy nor overlapping sutures appear to be mandatory for a successful repair of the anal sphincter after trauma.
