Case Report: First case of percutaneous transhepatic cholangioscopy guided triple bridge drainage between multiple bile ducts for malignant hilar biliary obstruction.

ABSTRACT:

Background

Biliary drainage for advanced malignant hilar biliary obstruction (MHBO) remains a significant challenge in current clinical practice.

Case description

A 58-year-old male diagnosed with unresectable advanced intrahepatic cholangiocarcinoma with hilar obstruction and required palliative biliary drainage. Imaging revealed obstruction of the common bile duct, left hepatic duct, right anterior hepatic duct, and right posterior hepatic duct (Bismuth-Corlette type IV). Due to the failure of ERCP, we decided to bridge biliary drainage with percutaneous transhepatic cholangioscopy (PTCS) after multidisciplinary discussion. First, one-step PTCS was used to establish a channel between the skin and the right anterior hepatic duct. Then a puncture needle was used to puncture
