Robotic colorectal resection with and without the use of the new Integrated Table Motion for da Vinci Xi: a case matched study

<b>Purpose:</b> To compare operative and short-term outcomes of patients undergoing colorectal cancer surgery with the da Vinci Xi system with or without use of the integrated table motion (ITM) for da Vinci Xi.<b>Methods:</b> The intraoperative and short-term clinical outcome were compared, using case-control methodology (propensity scores approach to create 1:2 matched pairs), with a similar group of patients who underwent robotic colorectal surgery for cancer without the use of the ITM device (Xi only group).<b>Conclusions: </b>In this preliminary experience, the use of new ITM for da Vinci Xi in colorectal surgery, by enhancing workflow, resulted in a reduced overall robotic operative time, lower postoperative medical morbidity and possibly a lower conversion rates.

**研究目的**：对比接受达芬奇Xi（da Vinci Xi）手术系统行结直肠癌手术的患者，在使用或不使用该系统配套的集成床身移动（integrated table motion, ITM）装置时的手术相关结局与短期预后情况。
**研究方法**：采用病例对照研究设计，通过倾向得分匹配法构建1:2配比配对样本，将使用ITM装置的患者与未使用该装置的同类结直肠癌机器人手术患者（仅达芬奇Xi组），就术中及短期临床结局开展对比分析。
**研究结论**：基于本次初步临床经验，在结直肠癌机器人手术中应用达芬奇Xi配套的新型ITM装置，可通过优化手术流程，缩短整体机器人手术时长，降低术后内科并发症发生率，同时可能降低中转开放手术率。
