Background: Minimally invasive approaches have become the standard of care for ileal pouch-anal anastomoses (IPAA). There are few reports comparing outcomes following a laparoscopic versus robotic approach. Our aim was to determine if there were any differences in the 30-day postoperative outcomes following IPAA performed laparoscopically versus robotically. Methods: A retrospective chart review of all laparoscopic and robotic IPAA performed between January 1, 2015 and June 30, 2018 was carried out. Patients included were adult patients who underwent a proctectomy and IPAA utilizing either a laparoscopic or robotic approach. Data collected included patient demographics, operative variables, and 30-day postoperative outcomes. Results: A total of 132 patients had a minimally invasive IPAA; 58 were performed laparoscopically and 74 robotically. Less than half the patients were female (n = 55; 41.7%) with a median age of 37 years (range 18–68 years). The majority of patients had a diagnosis of ulcerative colitis (n = 103; 78.0%) with medically refractory disease (n = 87; 65.9%). A greater proportion of patients in the laparoscopic cohort had a prolonged length of stay (n = 27; 46.6% versus n = 18; 24.3%; p < 0.001) and a two-stage approach (n = 56; 96.6% versus n = 37; 50%; p < 0.001), but there were no differences in the rates between the laparoscopic versus robotic cohorts of superficial surgical site infection (6.9% versus 6.8%; p = 0.99), peripouch abscess (15.5% versus 6.8%; p = 0.11), anastomotic leak (6.9% versus 2.7%; p = 0.21), pelvic abscess (15.5% versus 6.8%; p = 0.11), and pelvic sepsis (15.5% versus 6.8%; p = 0.11), readmission (24.1% versus 17.6%; p = 0.35) or reoperation (6.9% versus 5.4%; p = 0.72). On multivariable analysis, only male sex remained predictive of prolonged length of stay, and a robotic approach trended toward a decreased rate of prolonged length of stay. Conclusions: Laparoscopic and robotic IPAA have equivalent postoperative morbidity underscoring the safety of the continued expansion of the robotic platform for pouch surgery.
