Safety and effectiveness of endobiliary radiofrequency ablation according to the different power and target temperature in a swine model

Background and Aim Endobiliary radiofrequency ablation (EB‐RFA) is a new endoscopic palliation and adjunctive tool. Although EB‐RFA is performed worldwide, a possibility of iatrogenic thermal injury leading to perforation or bleeding still remains. Therefore, we aimed to assess the effects of thermal and coagulation injury after in vivo EB‐RFA using a new catheter with a temperature sensor in a swine model. Methods Twelve mini pigs were divided...
