Percutaneous intraductal radiofrequency ablation combined with biliary stent placement for malignant biliary obstruction: A case report and review of the literature

Percutaneous management of unresectable malignant biliary obstruction remains challenging. Biliary radiofrequency ablation (RFA) using the Habib EndoHBP catheter is a new palliation therapy for malignant biliary obstruction. We report our initial experience of RFA for the management of malignant biliary obstruction. A 58-year-old male was diagnosed with gallbladder cancer. Intraductal bipolar RFA was delivered at power of 10 W for 120 s, followed by stent placement. The patient had immediate stricture improvements after RFA. No severe adverse event occurred. Percutaneous RFA seems to be safe and feasible for the treatment of malignant biliary obstruction. Further studies are warranted.
