Fig. 3. The multiple hepatic ducts encountered during the bilioenteric anastomosis. In the case of bilioenteric anastomosis, if several openings of the hepatic duct (white circle) are encountered when the proximal hepatic duct was resected to secure a cancer-free margin, anastomosis is not possible with simple laparoscopic tools. However, with the help of the robot, complex anastomosis could be successfully performed without conversion to open surgery.
