[A modified autotransplantation method providing for continence in preternatural anus].

Over the period 1996 through 1998, a series of 58 patients undergo operation in the clinic of coloproctology--Medical University, Varna and in the clinic of surgery at the Naval Hospital--Varna, for continent preternatural anus formation on the anterior abdominal wall. A personal modification of Schmidt's (1978) method is used where a smooth-muscle cuff exerting pressure on the terminal segment of the large bowel, brought out as an artificial anus, is created. The operative procedure is combined with periodic colon irrigations in the postoperative period for the purpose of stimulating controlled intestinal content evacuation. The degree of continence is evaluated clinically and manometrically in all cases at termination of the first postoperative month, and in 31 of them--at the end of the second postoperative year. The early and late results are good.
