Abstract Purpose To determine the safety and efficacy of percutaneous intraductal radiofrequency ablation (RFA) combined with biliary metal stent placement for patients with unresectable malignant biliary obstruction. Methods From a cohort of 70 patients with unresectable malignant biliary obstruction, 28 patients received percutaneous intraductal RFA combined with biliary stent placement (group A) and the remaining 42 were treated with biliary metal stent placement only (group B). Stent patency, overall survival (OS), alleviation of jaundice, and postoperative complications were assessed. Results The technical success rate for both groups was 100%. No severe complications (e.g., biliary bleeding, perforation) occurred. In both groups, jaundice was relieved and the decrease of the total and direct bilirubin concentration was significant (p
