Single-port plus an additional port robotic complete mesocolic excision and intracorporeal anastomosis using a robotic stapler for right-sided colon cancer.

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant. The total operative and docking times were 280 and 25 minutes, respectively. The total number of lymph nodes harvested was 36 and the proximal and distal resection margins were 31 and 50 cm, respectively. Single-port plus an additional port robotic surgery for right-sided complete mesocolic excision and intracorporeal anastomosis appears to be feasible and safe. This system can overcome certain limitations of the previous robotic systems and conventional single-port laparoscopic surgery.
