Abstract: At present, the percutaneous transhepatic cholangiodrainage (PTCD) and the self-expandable metal stent implantation are commonly recognized as an effective treatment for inoperable malignant biliary obstruction, but the restenosis of biliary stent significantly affect the therapeutic result and prognosis.Percutaneous transhepatic intraductal radiofrequency ablation can be used together with biliary stent implantation, which can prolong the patency time of biliary stent and control the local tumor at the narrowed segment, thus, the therapeutic effect of malignant biliary obstruction can be reliably improved. As a kind of newly-developed therapy, its clinical safety is especially important. This paper aims to make a review about the safety of percutaneous transhepatic intraductal radiofrequency ablation combined with biliary stent implantation in treating malignant biliary obstruction.
