Abstract
ObjectiveTo identify trends in complications following robot-assisted radical cystectomy (RARC) using a multi-institutional database, the International Robotic Cystectomy Consortium (IRCC). MethodsA retrospective review of the IRCC database was performed (2976 patients, 26 institutions from 11 countries). Postoperative complications were categorized as overall or high grade (≥ Clavien Dindo III) and were further categorized based on type/organ site. Descriptive statistics was used to summarize the data. Multivariate analysis (MVA) was used to identify variables associated with overall and high-grade complications. Cochran-Armitage trend test was used to describe the trend of complications over time. Results1777 (60%) patients developed postoperative complications following RARC, 51% of complications occurred within 30 days of RARC, 19% between 30-90 days, and 30% after 90 days. 835 patients (28%) experienced high-grade complications. Infectious complications (25%) were the most prevalent, while bleeding (1%) was the least. The incidence of complications was stable between 2002-2021. Gastrointestinal and neurologic postoperative complications increased significantly (P < .01, for both) between 2005 and 2020 while thromboembolic (P = .03) and wound complications (P < .01) decreased. On MVA, BMI (OR 1.03, 95%CI 1.01-1.05, P < .01), prior abdominal surgery (OR 1.26, 95%CI 1.03-1.56, P = .03), receipt of neobladder (OR 1.52, 95%CI 1.17-1.99, P < .01), positive nodal disease (OR 1.33, 95%CI 1.05-1.70, P = .02), length of inpatient stay (OR 1.04, 95%CI 1.02-1.05, P < .01) and ICU admission (OR 1.67, 95%CI 1.36-2.06, P < .01) were associated with high-grade complications. ConclusionOverall and high-grade complications after RARC remained stable between 2002-2021. GI and neurologic complications increased, while thromboembolic and wound complications decreased.
