The robotic system for surgery was introduced to gastric cancer surgery in the early 2000s to overcome the shortcomings of laparoscopic surgery. The more recently introduced da Vinci Xi system offers benefits allowing four-quadrant access, greater range of motion, and easier docking through an overhead boom rotation with laser targeting. We aimed to identify whether the Xi system provides actual advantages over the Si system in gastrectomy for gastric cancer by comparing the operative outcomes.
We retrospectively reviewed all patients who underwent robotic gastrectomy as treatment for gastric cancer from March 2016 to March 2017. Patients' demographic data, perioperative information, and operative and pathological outcomes were collected and analyzed.
A total of 109 patients were included in the Xi group and 179 in the Si group. Demographic characteristics were similar in both groups. The mean operative time was 229.9 minutes in the Xi group and 223.7 minutes in the Si group. The mean estimated blood loss was 72.7 mL in the Xi group and 62.1 mL in the Si group. No patient in the Xi group was converted to open or laparoscopy, while 3 patients in the Si group were converted, 2 to open surgery and 1 to laparoscopy, this difference was not statistically significant. Bowel function was resumed 3 days after surgery, while soft diet was initiated 4 days after surgery.
We found no difference in surgical outcomes after robotic gastrectomy for gastric cancer between the da Vinci Xi and da Vinci Si procedures.
21世纪初，手术机器人系统被引入胃癌手术，以克服腹腔镜手术的缺点。最近推出的达芬奇Xi系统具有诸多优势，可实现四象限操作、更大的活动范围，并且通过带有激光定位的高架悬臂旋转更易于对接。我们旨在通过比较手术结果，确定Xi系统在胃癌胃切除术中是否比Si系统具有实际优势。
我们回顾性分析了2016年3月至2017年3月期间所有接受机器人胃癌切除术治疗的患者。收集并分析患者的人口统计学数据、围手术期信息以及手术和病理结果。
Xi组共纳入109例患者，Si组共纳入179例患者。两组的人口统计学特征相似。Xi组的平均手术时间为229.9分钟，Si组为223.7分钟。Xi组的平均估计失血量为72.7 mL，Si组为62.1 mL。Xi组无患者转为开放手术或腹腔镜手术，而Si组有3例患者转为开放手术，2例转为腹腔镜手术，1例转为开放手术，这种差异无统计学意义。术后3天恢复肠道功能，术后4天开始进软食。
我们发现达芬奇Xi手术和达芬奇Si手术在机器人胃癌切除术后的手术结果上没有差异。
