Best method to visualize the proximal bile duct is by:: (A) Percutaneous transhepatic cholangiogram, (B) EUS, (C) ERCP, (D) Transabdominal USG

IOC for proximal pa of biliary tract = Percutaneous transhepatic cholangiogram (both diagnostic and therapeutic) IOC for distal pa of biliary tract = ERCP (both diagnostic and therapeutic) IOC for most of biliary tract pathology like (CBD stone; choledochal cyst; biliary stricture; cholangiocarcinoma) = MRCP (only diagnostic)
