Successful Percutaneous Endobiliary Radiofrequency Ablation for Unresectable Malignant Biliary Obstruction: A Case Report and Review of the Literature

Periampullary adenocarcinoma (PA) is a rare cause of gastrointestinal malignancy . Surgical resection remains the only chance for cure ; however, even with surgery, 5-year overall survival ranges from 28 to 38 % [3, 4]. Unfortunately, up to 80 % of PAs present at an advanced stage and are surgically unresectable . Biliary obstruction is a frequent manifestation of PA. A multidisciplinary team including oncologists, surgeons, gastroenterologists, and interventional radiologists usually manages PA . Traditionally, endoscopy has been used to relieve malignant biliary obstruction using self-expanding metal stents (SEMSs) . Recently, interventional endoscopy has been employed to deliver direct therapy, such as brachytherapy or photodynamic therapy, to tumors to relieve biliary obstruction . Endobiliary radiofrequency ablation (RFA) is a novel technique that delivers heat energy directly to neoplastic tissues to achieve tumor necrosis and prolong biliary...
