Anterior resection with rectopexy is considered by many to be the best operation for rectal prolapse. It is feared that if sigmoid redundancy created by rectal mobilization is not resected, colonic motility (specifically constipation) could be disabling. We contend that resection is not necessary in patients without preexisting constipation. We tested this hypothesis using a laparoscopic approach to minimize hospital stay. Twelve patients were treated (eight women); mean age was 45 years (range, 25-82 years). No patient had preexisting constipation; one had irritable bowel syndrome. Three patients had prior prolapse operations. Full rectal mobilization was undertaken down to the levator hiatus; neither the mesenteric vessels nor the lateral ligaments were divided. Rectopexy to the presacral fascia was done with one to two Nurolon sutures on either side of the rectum. There were no complications; mean hospital stay was 4 days. Mean follow up was 32 months (range; 3-75 months); there have been no recurrences. Only the patient with irritable bowel syndrome developed significant constipation. We conclude: 1) rectopexy can be safely done laparoscopically, 2) resection is not required in the absence of prior constipation, and 3) rectal mobilization and rectopexy does not predispose to future constipation in these selected patients.
