Antecedent Bile duct Cutting in the Glissonean pedicle technique (ABC technique) for extremely advanced perihilar cholangiocarcinoma

摘要

Background: In an increasing number of patients undergoing radical surgery for perihilar cholangiocarcinoma [1-3], the intrahepatic bile duct is conventionally transected after the vessels to be preserved or reconstructed are confirmed [3,4]. In patients with extremely advanced perihilar cholangiocarcinoma having massive vascular involvement, it is sometimes difficult to confirm the vessels for reconstruction because of restricted working space and/or anatomical variants, even after liver parenchymal dissection [4]. When the vessels cannot be confirmed, the tumor is usually unresectable [4].
