Total Hilar En Bloc Resection with Left Hemihepatectomy and Caudate Lobectomy: a Novel Approach for Treatment of Left-Sided Perihilar Cholangiocarcinoma (with Video).

Background: "Hilar en bloc resection" using a no-touch technique has been advocated as a standard procedure in right-sided hepatectomies for treatment of perihilar cholangiocarcinoma (PHC). In principle, it has never been reported for left-sided tumors. The aim is to describe the procedures of total hilar en bloc resection with left hemihepatectomy and caudate lobectomy (THER-LH) for advanced PHC and discuss feasibility and clinical significance of this novel technique.
