摘　　要：Recently,endoscopic intraductal radiofrequency ablation(ID-RFA)has attracted attention as a local treatment method for malignant biliary obstruction(MBO).IDRFA causes coagulative necrosis of the tumor tissue in the stricture and induces exfoliation.Its effects are expected to extend the patency period of biliary stents and prolong the survival period.Evidence for extrahepatic cholangiocarcinoma(eCCA)is gradually accumulating,and some reports show significant therapeutic effects in eCCA patients without distant metastasis.However,it is still far from an established treatment technique,and many unsolved problems remain.Therefore,when performing ID-RFA in clinical practice,it is necessary to understand and grasp the current evidence well and to operate appropriately for the true benefit of the patients.This paper reviews the current status,issues,and prospects of endoscopic ID-RFA for MBO,especially for eCCA.
