Abstract

Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) is the gold standard surgical treatment for ulcerative colitis. However, despite the widespread use of RP-IPAA, many aspects of this treatment still remain controversial, such as the approach (open or laparoscopic), number of stages in the surgery, type of pouch, and construction type (hand-sewn or stapled ileal pouch-anal anastomosis). The present narrative review aims to discuss current evidence on the short-, mid-, and long-term results of each of these technical alternatives as well as their benefits and disadvantages. A review of the MEDLINE, EMBASE, and Ovid databases was performed to identify studies published through March 2016. Few large, randomized, controlled studies have been conducted, which limits the conclusions that can be drawn regarding controversial issues. The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases. Regarding 2- and 3-stage RP-IPAA, patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables, making any comparisons extremely difficult. The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly, although the J pouch is generally preferred by surgeons. Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages, and there is no clear benefit of one technique over the other.

Core tip: Restorative proctocolectomy with ileal pouch-anal anastomosis (RP-IPAA) is the preferred surgical treatment for ulcerative colitis. However, despite the widespread use of RP-IPAA, many aspects of this treatment still remain controversial, such as the approach (open or laparoscopic), number of stages of surgery, type of pouch, and type of construction (e.g., hand-sewn or stapled ileal pouch-anal anastomosis). Few large, randomized, controlled studies have been conducted, which limits the conclusions that can be drawn regarding controversial issues associated with RP-IPAA. It is suggested that prospective, randomized studies should be conducted in the future to compare the frequency of post-operative complications, cosmetic results, short- and long-term functional outcomes, and quality of life associated with the available techniques of RT-IPAA for the treatment of ulcerative colitis.
