Robotic Right Hepatectomy with En Bloc Caudatectomy for Bismuth IIIa Hilar Cholangiocarcinoma: A Video Demonstration of Left-Liver-First Anterior Radical Modular Orthotopic Right Hemihepatectomy.

Robotic left-liver-first anterior radical modular orthotopic right hemihepatectomy for Bismuth IIIa HCCA is both safe and feasible. This method may provide a new surgical approach for patients with type IIIA HCCA or liver diseases requiring right hemihepatectomy combined with total caudate lobectomy.
