Percutaneous endobiliary ablation of malignant biliary strictures with a novel temperature-controlled radiofrequency ablation device

Purpose We aimed to determine the safety and effectiveness of percutaneous endobiliary radiofrequency ablation malignant biliary obstructions with a temperature-controlled device. Methods In this single center retrospective study, total 62 consecutive patients obstruction were evaluated. Thirty who underwent metallic stent placement in study group 32 only stenting control group. Outcomes technical success, complications related procedure, patency, overall survival. Results All procedures technically successful both groups. There was no procedure-related mortality either Procedural complication rates similar between Although statistically not significant, two major (hemobilia requiring endovascular treatment) Median primary patency significantly longer than (223 days vs. 158 days; P = 0.016). survival also (246 198 0.004). Conclusion Percutaneous is safe feasible novel device obstruction. has potential improve
