¹Designated as “extended” radical cholecystectomy (modified Glenn operation) at our department since 1982;

²Cholecystectomy with full-thickness dissection: cholecystectomy combined with removal of the cystic plate;

³Resection of Couinaud segments IV, V, and VIII;

⁴Left hemihepatectomy extended to an inferior portion of the right anterior section. C: Cholecystectomy; WR: Wedge resection of the gallbladder fossa; BD: Bile duct resection; N: Regional lymphadenectomy; ERH: Extended right hepatectomy (right hemihepatectomy extended to an inferior portion of Couinaud segment 4); PD: Whipple pancreaticoduodenectomy; PPPD: Pylorus-preserving pancreaticoduodenectomy.
