[Long-term results of formation of smooth muscle sphincter in the perineal colostomy area in patients after rectal extirpation].

The authors discuss an original method for formation of a smooth-muscle cuff from the wall of a pulled-through colon in the region of a perineal colostoma. It was applied in 89 patients who had undergone extirpation of the rectum for malignant neoplasms. The smooth-muscle sphincter was formed during removal of the rectum in 72 patients and no earlier than 2 years after the extirpation in 17 patients. Inflammatory complications developed in the region of the perineal colostoa in the early postoperative period in 13.5% of cases. They were due to necrosis of the distal part of the pulled-through intestine in 3.4% of cases. There were no fatal outcomes. The late-term results were studied in follow-up periods of up to 7.5 years. Satisfactory functional results were produced in 83% of the patients. Physiological examination showed the presence of a functioning sphincter in the region of the perineal colostoma.
