340 radiofrequency ablation has comparable overall survival to photodynamic therapy in the treatment of cholangiocarcinoma and ampullary carcinoma

Endoscopic biliary stenting is an established palliation for unresectable biliary malignancies. However only bile duct drainage has limited effect in prolonging patients ’ survival. Both radiofrequency ablation (RFA) and photodynamic therapy (PDT) are associated with improved survival compared with stent placement alone. However, there are no researches about directly comparing RFA with PDT in patients with cholangiocarcinoma (CCA) or ampullary carcinoma. The aim of this study was to compare overall survival in patients diagnosed unresectable CCA or ampullary carcinoma who underwent palliative endoscopic RFA versus PDT.
