Endobiliary radiofrequency ablation for distal extrahepatic cholangiocarcinoma: A clinicopathological study

Background Most patients with distal extrahepatic cholangiocarcinoma have developed jaundice or cholangitis at the time of initial diagnosis, which can delay surgery. We aim to evaluate the actual EB-RFA ablation volume and validated the clinical feasibility of preoperative endobiliary radiofrequency ablation (EB-RFA) for resectable distal extrahepatic cholangiocarcinoma. Methods The medical records of patients who underwent EB-RFA from July...
