Mesohepatectomy: an Emerging Technique

Abstract

Mesohepatectomy is derived from the Greek word Meso = Middle. Hence it is also called by various names as Central Hepatectomy, Central bi-trisegmentectomy, Middle Lobectomy and Middle Hepatic Resection [1]. It is undoubtedly a rare procedure [2] that was, historically, restricted to the resection of hilar cholangiocarcinomas (in order to obtain surgical margins) and for the treatment of biliary strictures [3]. Of late, this technique of mesohepatectomy is being increasingly used for surgical removal of centrally located hepatocellular carcinomas and gall bladder cancers [3]. Mesohepatectomy involves removal of liver segments that are drained by the middle hepatic vein i.e. segments IV, V and VIII.
