Abstract
Endoscopic placement of biliary stents to relieve jaundice is the main palliative treatment for unresectable extrahepatic cholangiocarcinoma. Endoscopic biliary radiofrequency ablation (RFA) has been reported to prolong stent patency, which may be beneficial in improving patient survival. However, available evidence is still insufficient, as most reported studies are retrospective case series. The aim of this study was to explore the clinical effect and safety of RFA in patients with unresectable extrahepatic cholangiocarcinoma.
