The ANSUR surgical unit is a newly formulated robot that plays the roles of both the first assistant and scopist. This surgical unit was approved as a medical device in Japan in 2023. We report the first case of robot-assisted laparoscopic sigmoid resection for sigmoid colon cancer using the ANSUR surgical unit.
Robot-assisted laparoscopic sigmoid resection using the ANSUR surgical unit was planned for a 69-year-old woman with advanced sigmoid colon cancer.
Tumor resection was successfully completed without conversion to open surgery. The operative time was 147 min, and the estimated blood loss was 36 mL. The roll-in, roll-out, docking, and undocking times were 182, 36, 387, and 41 s, respectively. No mechanical failure or malfunction of the surgical unit was observed. Moreover, no adverse events related to the surgical unit were observed. The patient was discharged 5 days postoperatively without complications. The histopathological diagnosis was T3N1aM0, stage IIIB, with clear proximal and distal resection margins. During follow-up 30 days later, an uneventful patient recovery was noted.
This is the first case of robot-assisted laparoscopic sigmoid resection for sigmoid colon cancer using the ANSUR surgical unit. The procedure was performed with technical and oncological safety.
ANSUR手术单元是一种新研发的机器人，兼具第一助手和摄像师的功能。该手术单元于2023年在日本获批为医疗器械。我们报告首例使用ANSUR手术单元进行机器人辅助腹腔镜乙状结肠癌切除术的病例。
计划对一名69岁的晚期乙状结肠癌女性患者使用ANSUR手术单元进行机器人辅助腹腔镜乙状结肠切除术。
成功完成肿瘤切除，未转为开放手术。手术时间为147分钟，估计失血量为36毫升。移入、移出、对接和脱开对接时间分别为182秒、36秒、387秒和41秒。未观察到手术单元出现机械故障或功能异常。此外，未观察到与手术单元相关的不良事件。患者术后5天出院，无并发症。组织病理学诊断为T3N1aM0，IIIB期，切缘近端和远端均清晰。30天后随访时，患者恢复顺利。
这是首例使用ANSUR手术单元进行机器人辅助腹腔镜乙状结肠癌切除术的病例。该手术在技术和肿瘤学方面均安全可行。
