[ROBOT-ASSISTED RADICAL CYSTECTOMY AT HIROSHIMA CITY ASA HOSPITAL -COMPARISON WITH LAPAROSCOPIC RADICAL CYSTECTOMY].

Abstract

(Objective) We compared the perioperative parameters of robot-assisted radical cystectomy (RARC) and laparoscopic radical cystectomy (LRC) to evaluate the utility of RARC. (Patients and methods) At Hiroshima City Asa Hospital, 25 patients underwent RARC from July 2018 to May 2020 (R group) and 79 patients underwent LRC from July 2012 to June 2018 (L group). We retrospectively compared the patient characteristics, perioperative outcomes, and pathological outcomes between the R group and the L group. (Results) Regarding the patient characteristics, the R group had significantly more neo-adjuvant chemotherapy than the L group (64.0% vs. 32.9%, P=0.009), but the other characteristics did not differ. Between the R group and the L group, there were no significant differences in the total operating time (R group = 400 minutes vs. L group = 421 minutes), estimated blood loss (R group = 228 ml vs. L group = 318 ml), or pathological outcomes. However, there were significantly less postoperative complications in the R group than in the L group (24.0% vs. 52.6%, P=0.020). (Conclusion) This study showed that there might be benefits to introducing RARC into medical centers that perform LRC.
