Fig. 2. Docking of the surgical robotic system. Among the pre-used trocars for laparoscopic instruments during the resection stage (A), only 3 were replaced with the robot, including a trocar for the scope in the umbilicus and two 8-mm trocars at the right hypogastrium and subcostal location (B), without additional trocar insertion. Robotic reconstruction was performed by docking the robot arms at these 3 trocar sites.
