Hepatectomy of segment 4a and 5 combined with extra‐hepatic bile duct resection for T2 and T3 gallbladder carcinoma

Abstract

S4a + 5 combined with BDR and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 GB Ca. Further extension of the operation, such as the addition of PD (PpPD) or an extended hepatectomy, should be carefully modified for each individual according to the cancer spread mode.
