EUS-guided Radiofrequency Ablation (EUS-RFA) of Solid Pancreatic Neoplasm Using an 18-gauge Needle Electrode: Feasibility, Safety, and Technical Success

Background & Aims: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is a promising technique for the treatment of pancreatic neoplasm. We evaluated the feasibility, safety, and technical success of pancreatic EUS-RFA performed in a single center.Methods: 9 consecutive patients (8 with pancreatic adenocarcinoma and 1 with renal cancer metastasis) were referred for EUS-RFA between November 2016 and July 2017. EUS-RFA was performed using 18-gauge internally cooled electrode with a 5 or 10 mm exposed tip. Feasibility, technical success or early and late adverse events were assessed.Results: One patient was excluded because of a large necrotic portion. EUS-RFA was feasible in all the other 8 (100%) cases. An ablated area inside the tumor was achieved in all treated patients. No early or late major adverse event was observed after a mean follow-up of 6 months. Three patients experienced mild postprocedural abdominal pain.Conclusions: EUS-RFA seems a feasible, safe, and effective procedure for pancreatic neoplasms. Its role in the treatment and management of pancreatic masses must be further investigated.
