Abstract

This case report presents a 73-year-old male with recurrent hepatocellular carcinoma who underwent serial surgical and interventional locoregional treatments, which resulted in asymptomatic intrahepatic bile duct dilatation. To address a recurrent tumor close to the pre-existing dilated bile ducts, radiofrequency ablation was performed, leading to a biliocutaneous fistula along the electrode tract. Attempts to close the refractory fistula by percutaneous transhepatic cholangial diversion and balloon dilatation of the stenotic central bile duct were unsuccessful. Ultimately, the fistula was successfully sealed with aggressive management, combining balloon-assisted retrograde fistulography and antegrade fistula embolization. This report aims to raise awareness of complex biliary complications after radiofrequency ablation in patients with preexisting bile duct dilatation, and emphasize the importance of aggressive intervention in cases of refractory biliocutaneous fistula based on our experience.
