Robot‐Assisted Radical Cystectomy With Intracorporeal Ileal Conduit Using the Hinotori Surgical Robot System: A Single Surgeon's Initial Experience of 20 Cases

Abstract

BACKGROUND: The objective of this study was to assess the perioperative outcomes of robot-assisted radical cystectomy (RARC) with intracorporeal ileal conduit (ICIC) using the hinotori surgical robot system. METHODS: This retrospective study included 20 consecutive patients with bladder cancer who underwent RARC with ICIC using hinotori from October 2023 to July 2024. Major perioperative outcomes were comprehensively analysed. RESULTS: The median operative time, time using the robotic system, bowel reconstruction and urinary diversion time, and estimated blood loss were 435.0, 330.0, 122.5 min, and 175.0 mL, respectively. No marked intraoperative complications were observed. Perioperative, 30-day, and 90-day complications occurred at rates of 25%, 10%, and 0%, respectively. The learning curve tended to decrease in a case volume-dependent manner. CONCLUSIONS: RARC using hinotori was successfully completed, and favourable perioperative outcomes were achieved without severe complications. This suggests that RARC using hinotori provides a potentially comparable alternative to conventional surgical systems.
