P.05.45 ENDOSCOPIC RADIOFREQUENCY ABLATION FOR EXTRAHEPATIC MALIGNANT BILIARY OBSTRUCTION: SAFETY AND EFFICACY OF A SINGLE CENTER EXPERIENCE

Malignant biliary obstruction is often secondary to pancreatic cancer or cholangiocarcinoma. Most of patients present at advanced stage with a short life expectancy and no chance of resolutive therapy. patients with ingravescent icterus, endoscopic drainage is performed with position of metal or plastic biliary stents. Radiofrequency ablation (RFA) have already been studied to improve stent patency and to treat liver lesions percutaneous via. The aim of our study is to assess efficacy and safety of RFA ablation in patients unfit for surgery with malignant biliary obstruction due to extrahepatic colangiocarcinoma.
