Defining the association between the prolonged operative time and 90-day complications in patients undergoing radical cystectomy

Research output: Contribution to journalArticlepeer-review

Abstract

Objective: Radical cystectomy is a complex lengthy procedure associated with postoperative morbidity. We aimed to assess the operative time (OT) in patients undergoing radical cystectomy and its impact on 90-day postoperative complications and readmission rates. Methods: The retrospective cohort study included 296 patients undergoing radical cystectomy and urinary diversion from May 2010 to December 2018 in our institution. The OT of 369 min was set as a cutoff value between short and long OT groups. The primary outcome was 90-day postoperative complication rates. Secondary outcomes were gastrointestinal recovery time, length of hospital stay, and 90-day readmission rates. Results: The overall incidence of 90-day postoperative complications was 79.7% where 43.2% representing low-grade complications according to the Clavien -Dindo classification (Grade 1 and Grade 2), and 36.5% representing high-grade complications (Grade≥3). Gastrointestinal tract and infectious complications are the most common complications in our data set (45.9% and 45.6%, respectively). On multivariable analysis, prolonged OT was significantly associated with odds of high-grade complications (odds ratio 2.340, 95% confidence interval 1.288–4.250, p=0.005). After propensity score-matched analysis, a higher incidence of major complications was identified in the long OT group 55 (51.4%) compared to 35 (32.7%) in the short OT group (p=0.006). A shorter gastrointestinal tract recovery time was noticed in the short OT group (p=0.009). Prolonged OT was associated with a higher 90-day readmission rate on univariate and multivariate analysis (p< 0.001, p=0.001, respectively). Conclusion: Prolonged OT (>369 min) is associated with an increased risk of postoperative complications and readmission rates. The perception of potential postoperative complications requires careful monitoring of these patients which could translate into better operative outcomes.
