Background: Radical cystectomy (RC) is standard of care for muscle-invasive bladder cancer, but it comes with significant perioperative risk, with half of the patients experiencing major postoperative complications. Robot-assisted radical cystectomies (RARCs) have aimed to decrease patient morbidity and been increasingly adopted in North America. Currently, both open radical cystectomies (ORCs) and RARCs are frequently performed. The aim of this study is to contribute to the existing literature using newly available data from the American College of Surgeons National Surgical Quality Improvement Project (NSQIP), representing one of the most recent, largest multi-institutional studies, while uniquely accounting for a variety of factors, including type of urinary diversion, cancer staging, and neoadjuvant chemotherapy. Methods: RC procedures performed between 2019 and 2021 were identified in NSQIP and the corresponding cystectomy-targeted database. Cases in the ORC group were planned open procedures, and cases in the RARC group were robot assisted, including unplanned conversion to open cases for intention to treat. Chi-square and t-tests were performed to compare baseline demographics and operative parameters. Multivariate analysis was performed for outcomes, including major complications, minor complications, and 30-day mortality rates, while adjusting for baseline differences significant on univariate analysis. Results: Five thousand three hundred forty-three RC cases were identified. Of these, 70% underwent planned ORC, while 30% received RARC. RARC was associated with longer operative times and shorter hospital length of stay compared with ORC. On multivariate analysis, there was no difference between the cohorts in 30-day rates of major complications, hospital readmissions, need for reoperation, or mortality. ORC was, however, associated with higher rates of minor complications, bleeding, superficial surgical site infections, and anastomotic leak. Conclusions: In the NSQIP database, ORC is associated with higher rates of 30-day minor complications, most notably bleeding, compared with RARC. However, there is no difference in regard to perioperative major morbidity or mortality rates. This study is unique in the size of the cohorts compared, timeliness of data (2019-2021), applicability to a variety of different practice settings across the country, and ability to control for factors, such as type of urinary diversion and pathological bladder cancer staging, as well as use of neoadjuvant chemotherapy. This study was approved by the Institutional Review Board (IRB) specific to Thomas Jefferson University.
