Overview
Brief Summary
This prospective, multicenter, randomized controlled clinical study compared the clinical utility of endoscopic biliary radiofrequency ablation combined with metallic stent implantation (test group) and stent implantation alone (control group) in patients with unresectable malignant extrahepatic bile duct. The goal was to do this. lim. Over a period of approximately 4 years from 2019 to April 2023, 82 out of 147 eligible subjects were registered, recording a registration rate of 56.5%. Despite extending the study period several times, the registration rate for clinical participation was low and the number of subjects registered was slow. Due to poor performance, it was judged impossible to reach the target number of subjects in the future, and the study was terminated in early April 2023 after consultation with all co-researchers. 1. Number of subjects registered at early termination of clinical trial: 39 in test group, 43 in control group 2. Total complication rate in the early stage of the procedure: 69% in the test group, 62% in the control group. 3. Initial mortality rate after endoscopic procedure: 0% in both groups 4. Average stent opening period: 75 days in the experimental group, 102 days in the control group. 5. Average survival period: test group 60 days, control group 196 days
