Role of robotic approach in ileal pouch-anal anastomosis (IPAA)- A systematic review of the literature

Le résumé fourni par la source

Abstract Restorative proctocolectomy with ileal-pouch anal anastomosis (IPAA) has become standard surgical treatment of choice in patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP) in which the medical management fails. Despite the wide use of laparoscopic method, the enhanced and innovative features that come with the robotic platform such as endo-wrist technology, 3D visualization, surgeon-controlled camera and motion scaling makes it an appealing choice. This study aims to investigate then feasibility and safety of robotic approach for proctectomy or proctocolectomy with IPAA as compared to conventional laparoscopic approach. A systematic review was done to for the studies done between 2010 and 2022 comparing the robotic approach with the laparoscopic approach and 9 studies were finally found to be feasible to be included in this review. In terms of the outcomes, although the mean operating time was slightly higher than the laparoscopic approach, the other outcomes such as mean blood loss, return of the bowel movement, mean hospital stay, and conversion to open were found to be significantly lower. Despite the overall increased rate of complications combined from all the studies, the rate of significant complications such as anastomotic leaks requiring readmission and return to theater was also found to be substantially less. This study concludes that although robotic approach is in its initial stages for pelvic surgeries, it can be safely employed due to improved dexterity and visibility.
