abstract
OBJECTIVE: To compare perioperative and oncological outcomes of intracorporeal (ICUD) vs extracorporeal urinary diversion (ECUD) after robot-assisted radical cystectomy (RARC). METHODS: From January 2014 to December 2017, data of consecutive patients who underwent RARC performed by 2 institutional surgeons were prospectively collected in a dedicated database (IRB: 251647). Patients were divided in 2 groups according to the operating surgeon, one performing ECUD, the other ICUD. Groups were compared in perioperative outcomes and Clavien complications (during admission, within 30- and 90-days postoperatively). Univariable and multivariable analyses tested the impact of variables of interest on the occurrence of complications at the different time points. Kaplan-Meier method was used to estimate recurrence and metastasis-free survivals. RESULTS: Sixty to 66 patients underwent RARC with ileal conduit ICUD and ECUD, respectively. ICUD patients were younger (69 vs 73 years old, P = .009). No differences were found in other baseline characteristics and final pathology. Regarding perioperative outcomes, shorter operative time favored ECUD (7 vs 6 hours, P = .0004). Specifically, no differences were found in postoperative complications while admitted, either overall (ICUD: 16 [26.7%] vs ECUD: 23 [34.8%] patients, P = .3) or major (ICUD: 10 [16.7%] vs ECUD: 14 [21.2%], P = .6); same was for reassessment within 30- and 90-days postoperatively. At multivariable analysis, Charlson's Comorbidity Index ≥3 and blood losses >600 mL predicted complications during the admission (P = .02). Male gender, higher body mass index, and ureteral involvement predicted 30-days complications (P = .04). No differences in oncological outcomes. CONCLUSION: At head-to-head comparison of 2 expert surgeons, ICUD and ECUD for ileal conduit had comparable perioperative outcomes.
