Core Tip
Core Tip: Intraductal radiofrequency ablation can be a useful option as a local therapy for malignant biliary obstruction, but there are still many unclear points. Although increasing reports suggest its usefulness, mainly for extrahepatic cholangiocarcinoma without distant metastasis, it is still far from being a standard treatment. Additionally, it should be recognized that the currently available ablation catheter could not always provide sufficient ablation in all cases. In addition to accumulating further evidence, it is necessary to establish its usefulness, clarify its indication, and develop an innovative device that can perform appropriate ablation for all lesions.
