Management of rectal prolapse: the role of laparoscopic approaches

Rectal prolapse is a lifestyle-altering disability which has been treated with over 100 surgical options. The specific goals of surgical management of full thickness rectal prolapse are to minimize the operative risk in this typically elderly population, eradicate the external prolapse of the rectum, improve continence, improve bowel function, and reduce the risk of recurrence. The theoretical advantages of a laparoscopic approach are to couple reductions in surgical morbidity and good post-operative outcome. Studies which compare the same laparoscopic and open surgical approach for rectal prolapse have demonstrated that laparoscopy confers benefits related to postoperative pain, length of hospital stay, and return of bowel function. Virtually every type of open transabdominal surgical approach to rectal prolapse has been laparoscopically accomplished. Current laparoscopic surgical techniques include suture rectopexy, stapled rectopexy, posterior mesh rectopexy with artificial material, and resection of the sigmoid colon with colorectal anastomosis, with or without rectopexy. The growing body of literature supports the concept that laparoscopic surgical techniques can safely provide the benefits of low recurrence rates and improved functional outcome for patients with full thickness rectal prolapse.
