Comparison of Surgical Outcomes Between the hinotori™ and da Vinci® Robotic Systems in Robot-Assisted Sacrocolpopexy: A Retrospective Study.

Abstract

Objective This study aimed to assess whether the hinotori™ surgical system (Medicaroid Corporation, Kobe, Japan), during its early clinical adoption, could achieve perioperative outcomes in robot-assisted sacrocolpopexy (RASC) for pelvic organ prolapse (POP) comparable to those of the established da Vinci® system (Intuitive Surgical, Sunnyvale, CA, USA). Materials and methods This single-center retrospective study included 23 patients who underwent RASC between September 2023 and December 2024. Eleven patients underwent surgery with the hinotori™ system (h-RASC), and twelve with the da Vinci® system (d-RASC). Operative time, console time, and stepwise procedural durations were evaluated. Results Patient characteristics were comparable between groups. Although console time showed no significant difference, operative time tended to be longer in the h-RASC group (275 vs. 242 minutes; p = 0.056), without reaching statistical significance. The time from robot roll-in to console start (16 vs. 7 minutes; p = 0.004) and posterior mesh fixation (16 vs. 12 minutes; p = 0.001) was significantly longer with the hinotori™ system. Other perioperative outcomes were similar. Conclusion RASC using the hinotori™ system produced comparable perioperative outcomes to those of the da Vinci® system, although some procedural delays were observed during the initial implementation period.
