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.

利用Hinotori手术机器人系统辅助根治性膀胱切除术伴体内回肠导管：单个外科医生20例的初步经验

本研究的目的是评估机器人辅助根治性膀胱切除术（RARC）与体内回肠导管（ICIC）使用hinotori手术机器人系统的围手术期效果。方法回顾性研究包括2023年10月至2024年7月期间连续20例膀胱癌患者行RARC联合ICIC治疗。综合分析围手术期主要结局。结果手术时间中位数为435.0 min，机器人系统使用时间中位数为330.0 min，肠重建和尿改道时间中位数为122.5 min，估计失血量中位数为175.0 mL。术中未见明显并发症。围手术期、30天和90天的并发症发生率分别为25%、10%和0%。学习曲线呈病例量相关的下降趋势。结论hinotori的RARC手术成功完成，围手术期预后良好，无严重并发症。这表明RARC使用hinotori提供了一种潜在的可与传统手术系统相媲美的替代方案。

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
