*Designated as ‘extended’ radical cholecystectomy at our department since 1982 [11,13,14].
†Cholecystectomy with full-thickness dissection: cholecystectomy combined with removal of the cystic plate.
‡Defined as removal of Couinaud segments IV, V, and VIII.
C, cholecystectomy; WR, wedge resection of the gallbladder fossa; BD, resection of the extrahepatic bile duct; N, regional lymphadenectomy; ERH, extended right hepatectomy (right hepatectomy extended to an inferior portion of Couinaud segment 4); ELH, extended left hepatectomy (left hepatectomy extended to an inferior portion of right anterior section); PD, Whipple pancreaticoduodenectomy; PPPD, pylorus-preserving pancreaticoduodenectomy.
