Dis Colon Rectum 1993:36;501-507 Open Approaches for Rectal Prolapse Summary • Lower recurrence rates but higher morbidity than perineal procedures • Fixation superior to pelvic floor repair, or resection alone • Posterior fixation superior results • Sutures alone comparable to mesh fixation • Less constipation with concomitant resection Open Approaches for Rectal Prolapse Conclusions Sigmoid resection with sutured rectopexy offers: • Low risk of recurrence • The long term avoidance of constipation • PROCEDURE OF CHOICE • (why not laparoscopically?)
