National trends and outcomes of total proctocolectomy and completion proctectomy ileal pouch−anal anastomosis procedures for ulcerative colitis

Abstract

AimThe purpose of this study is to assess US operative trends and outcomes of ulcerative colitis (UC) patients undergoing total proctocolectomy with ileal pouch−anal anastomosis (TPC‐IPAA) or completion proctectomy with IPAA (CP‐IPAA).MethodsAdult UC patients who underwent TPC‐IPAA or CP‐IPAA were analysed retrospectively using the 2016–2020 American College of Surgeons National Surgical Quality Improvement Program database. Factors associated with 30‐day overall and serious morbidity were identified using multivariable logistic regression.ResultsA total of 1696 patients were identified, with 958 patients (56.5%) undergoing TPC‐IPAA and 738 (43.5%) undergoing CP‐IPAA. A greater proportion of TPC‐IPAAs were performed each year (except in 2019) compared to CP‐IPAAs over the study period (P trend <0.001). Unadjusted analysis showed comparable rates of overall (20.8% vs. 24.4%, P = 0.076) and serious morbidity (14.3% vs. 12.7%, P = 0.352) between TPC‐IPAA and CP‐IPAA patients. Robotic TPC‐IPAA had no differences in complications compared to laparoscopic and open approaches. Robotic CP‐IPAA had higher anastomotic leak rates and longer hospital length of stay compared to laparoscopic and open approaches. Obesity was associated with increased odds of overall and serious morbidity for patients who underwent TPC‐IPAA. Steroid/immunosuppressive therapy was associated with increased odds of overall and serious morbidity for patients who underwent CP‐IPAA.ConclusionsObese patients should be informed of their increased morbidity risk and offered counselling on weight loss prior to surgery when feasible. Patients on steroid/immunosuppressive therapy within 30 days preoperatively should not undergo CP‐IPAA or should delay surgery until they can be safely off those medications.
