Endobiliary RFA group
Control group
Endoscopic retrograde cholangiopancreatography (ERCP) would be performed under standard operating conditions to confirm the biliary malignancy. Subjects will receive endobiliary radiofrequency ablation (Endobiliary RFA) followed by plastic stent(s) placement. Three months later, subjects will receive the second RFA therapy followed by biliary stents (plastic or SEMS) placement. During follow-up, if stent occlusion occurs, the patient will undergo endoscopic re-intervention for stent exchange without endobiliary RFA
Endoscopic retrograde cholangiopancreatography (ERCP) would be performed under standard operating conditions to confirm the biliary malignancy. Subjects will receive plastic biliary stent(s) placement only. Three months later, subjects will receive the second endoscopic intervention for stents (plastic or SEMS) exchange. During follow-up, if stent occlusion occurs, the patient will undergo endoscopic re-intervention for stent exchange without endobiliary RFA
