LATE-TERM RESULTS OF FORMATION OF A SMOOT H-MUSCLE SPHINCTER IN THE REGION OF A PERINEAL COLOSTOMA IN PATIENTS AFTER EXTIRPATION OF THE RECTUM

The authors discuss an original method for formation of a smooth-muscl e cuff from the wall of a pulled-through colon in the region of a peri neal colostoma. It was applied in 89 patients who had undergone extirp ation of the rectum for malignant neoplasms. The smooth-muscle sphinct er was formed during removal of the rectum in 72 patients and no earli er than 2 years after the extirpation in 17 patients. Inflammatory com plications developed in the region of the perineal colostoma in the ea rly 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. T here were no fatal outcomes. The late-term results were studied in fol low-up periods of up to 7,5 years. Satisfactory functional results wer e produced in 83% of the patients. Physiological examination showed th e presence of a functioning sphincter in the region of the perineal co lostoma.
