title: Hepatic S4a + S5 and bile duct resection for gallbladder carcinoma.
abstract: In the surgical treatment of gallbladder cancer, segment 4a + 5 hepatic resection and bile duct resection is usually recommended for T2 and/or T3 gallbladder cancer involving hepatic parenchyma without hepatic biliary confluence. This procedure does not affect liver function excessively, provided there is correct identification of hepatic S4a and S5, the most important aspect of this procedure. In this paper, the technique of hepatic S4a + 5 and bile duct resection is described in detail. This surgical procedure could be a useful option for the surgical treatment of the hepatobiliary pancreatic malignancies. Surgeons should therefore master the surgical techniques for this procedure.
