Efficacy and safety of endoscopic radiofrequency ablation for unresectable extrahepatic cholangiocarcinoma: a randomized trial

Abstract

Endoscopic RFA combined with stenting can significantly prolong survival and the stent patency period without increasing the incidence of adverse events in patients with extrahepatic cholangiocarcinoma patient, except Bismuth type III and IV hilar cholangiocarcinoma. This approach can be considered as a safe and effective palliative treatment for these patients.
