Robotic complete mesocolic excision of right‑sided colon cancer with bulky lymph node metastases using the da Vinci® Si™ system: A case report

Xi™ system; however, with the increasing popularity of robotic surgery for the treatment of colon cancer, it is likely to be performed using the da Vinci Si™ and X™ systems. The present study reported the case of a 63-year-old woman who underwent complete mesocolic excision (CME) with the da Vinci Si system involving a rotation technique for ascending colon cancer with bulky lymph node metastasis to the anterior pancreas. Robot-assisted right hemicolectomy was planned for this patient with T4aN2bM0, stage IIIc cancer. A lap protector and EZ access (Hakko Co. Ltd.) were fixed in the umbilical incision, and the da Vinci camera port was placed just off-center at the EZ access to allow the camera port to be repositioned by rotating it. The medial approach was used. The bulky metastatic lymph nodes at the head of the pancreas were dissected after ligating the right colic artery and vein. During CME, rotation of the EZ access was used to avoid interference between the robotic arms. The right colon was released from the retroperitoneum and resected. A functional end-to-end anastomosis was created, and right colectomy was successfully completed. The total operation time was 271 min and the console time with the da Vinci Si system was 140 min. The patient was discharged on postoperative day 8 without complications. In conclusion, robotic right colectomy was successfully performed and rotation of the EZ access facilitated robotic surgery using the da Vinci Si system.
