ABSTRACT
Objective To evaluate the feasibility and effectiveness of percutaneous intraductal radiofrequency ablation (RFA) in treating biliary stent stenosis. Methods A total of 43 cases with biliary obstruction caused by biliary stent stenosis were enrolled in this study. Through percutaneous transhepatic pucturing of biliary duct, an EndoHPB catheter was placed in the stenotic site of the biliary stent, which was followed by RFA treatment. After RFA, biliary drainage catheter was reserved. The drainage catheter was removed when angiography confirmed that the stent was patent. Results Cholangiography showed that the biliary stent became patency after RFA in all patients. No procedure-related complications occurred. After RFA, the median patency time of the stenotic biliary stent in survival patients was 107 days (12-180 days). Conclusion The results of this preliminary clinical study indicate that percutaneous intraductal radiofrequency ablation has excellent effect and safety for the treatment of biliary stent stenosis, although more reliable and randomized controlled trials are needed before its effect and safety can be further proved.
