PERINEAL SIGMOIDECTOMY FOR SIGMOID PROCIDENTIA - REPORT OF A CASE

Although rectal procidentia is not an uncommon disease, presentation o f more proximal segments of the large bowel through the anus is extrem ely rare. We report a male patient with an acute sigmoid prolapse seco ndary to a large villous adenoma acting as the lead point. Since the p rolapsed segment was irreducible and exhibited signs of vascular compr omise, an intraoperative colonoscopy and perineal sigmoidectomy with a primary anastomosis was carried out. Postoperatively, the patient did well and was discharged 5 days after his operation. Recognition of th e difference between sigmoid and rectal procidentia should influence t he surgeon's choice of operation, along with the viability of the prol apsed bowel and overall condition of the patient.
