Abstract
PURPOSE: To evaluate the patency and clinical efficacy of percutaneous intraductal microwave ablation (PIMWA) and uncovered self-expandable metallic stents (USEMs) in inoperable malignant extrahepatic biliary obstruction. MATERIALS AND METHODS: The procedures to be performed on patients with malignant inoperable extrahepatic biliary obstruction were decided by a multidisciplinary team including an interventional radiologist. In our study, 141 patients were evaluated retrospectively. Twenty-one patients who underwent PIMWA + USEMs with the MedWaves AveCure microwave system (AveCure® Intelligent Controller and Super-Flex Smart Catheter) and met the inclusion criteria were included in the study. Complications related to the intervention, stent patency, survival time, serum bilirubin levels, and the general condition of the patients were noted. RESULTS: The median stent patency and the median survival time were 108 and 143 days, respectively. The rates of 30-day, 2-month, 6-month and 8-month survival were 95.2%, 85.7%, 38.1%, and 14.3%, respectively. CONCLUSION: The PIMWA + USEMs procedure is a safe, effective, and minimally invasive alternative palliative treatment method in patients with malignant inoperable extrahepatic biliary obstruction.
