The robotic approach improves the outcomes of ERAS protocol after radical cystectomy: A prospective case-control analysis

Background: Minimally-invasive approach is one of the mainstays of Enhanced Recovery After Surgery (ERAS) pathways. Robot-assisted radical cystectomy (RARC) introduction has reduced the surgical burden on patient's recovery. Accordingly, ERAS protocol benefits may be more striking in RARC patients. We evaluated the impact of surgical approach on perioperative outcomes, Fast Track (FT) recovery steps and Trifecta success rates in patients undergoing RC followed by FT protocol. Materials and methods: We considered 147 patients who underwent RC, with open (Open radical cystectomy [ORC]; 47.6%) or robotic (RARC; 52.4%) approach at 2 tertiary centers. Urinary diversions were ileal conduit or orthotopic neobladder. All patients underwent FT protocol. We analyzed perioperative surgical and functional outcomes and Trifecta success rates (namely, defecation <5 days, in-hospital stay <10 days and no major complications). Uni and multivariable logistic regression explored the predictors for Trifecta success and the impact of surgical approach on recovery steps. Results: Patients undergoing RARC had higher FT adherence (95% vs. 61%) compared to ORCs (P < 0.01). Trifecta success rates were higher for RARC (79.2% vs 28.6%; P < 0.001). At multivariable analyses, RARC was an independent predictor for Trifecta success (OR 9.1), early mobilization (OR 5.9) and FT adherence (OR 3.33; all P < 0.001). Surgical technique was not associated with major complications or readmission within 90 days (all P > 0.05). Conclusion: RARC has more favorable perioperative outcomes compared to ORC, with higher Trifecta success rates. Accordingly, robotic approach should be ideally included in every center where ERAS protocol is applied to RC for maximizing patient's recovery.
