For complete prolapse, conservative therapy may be used, but surgery should not be delayed. Surgery usually involves transabdominal resection of redundant colon and rectum, coloanal anastomosis, or both. However, surgeons disagree about which specific procedure is best. Complications include intestinal obstruction if the loop is tied too tightly and recurrence if the loop breaks. Postoperative fecal incontinence is common, particularly among patients with preoperative incontinence.
Many surgeons prefer to surgically tighten the sphincter in such patients.
