A novel technique for the internal drainage of extrahepatic biloma complicating transarterial embolization of hepatocellular carcinoma.

Biloma is an infrequent complication of nonsurgical treatments of hepatocellular carcinoma (HCC), including transarterial embolization (TAE), and it is often associated with ischemic injuries of the biliary tract after therapy. We here report on a case featuring successful internal drainage of an extrahepatic biloma into the duodenum by a route via the cholecyst, cholecystic duct, and common bile duct under fluoroscopic control. An extrahepatic biloma developed after urgent TAE for ruptured HCC and became contaminated.
