Biliary Obstruction After Transjugular Intrahepatic Portosystemic Shunt Placement.

A 19-year-old man with noncirrhotic portal hypertension status post transjugular intrahepatic portosystemic shunt, gastric esophageal varices status post coil embolization, and thrombophilia because of Factor V Leiden heterozygosity presented with jaundice and elevated liver enzymes. His cholangiogram during endoscopic retrograde cholangiopancreatography demonstrated biliary tract obstruction at the bifurcation of the right and left hepatic ducts. With the aid of digital single-operator cholangioscopy, the patient was found to have a perforation of the common hepatic duct from the shunt. This case presents a novel use for digital single-operator cholangioscopy in identifying this rare complication and appropriately differentiating biliary compression vs perforation from transjugular intrahepatic portosystemic shunt.
