Extended left hepatic lobectomy for hepatic hilar bile duct cancer: a novel surgical procedure in which the right hepatic duct is transected before the hepatoduodenal ligament is skeletonized

Abstract

As a general principle, the procedure of isolating a cancer region from surrounding tissues (skeletonization) is not taken until the last stage of a cancer operation. This principle is often disregarded in surgery for cancers of the hepatic hilar duct, however, as it may be mandatory to skeletonize the region before resecting the liver. Our group invented 'extended left hepatic lobectomy', a new surgical procedure for hepatic hilar bile duct cancer, in which we isolate the liver and transect the right hepatic duct before skeletonizing the cancer region in the hepatoduodenal ligament.
