Ethanol Ablation for Intrahepatic Bile Duct Dilatation in an Elderly Patient: A Case Report

Intrahepatic bile duct (IHBD) dilatations are a rare disease and can lead to the formation of intrahepatic stones, cholangitis, and even cholangiocarcinoma. Surgical resection of the affected segments has traditionally been considered the only effective approach in symptomatic patients. Here, we present the successful chemical ablation of the IHBD using ethanol through percutaneous transhepatic cholangial drainage in an 82-year-old patient who is at high risk for surgery.
