Endoscopic Ultrasound-Guided Direct Intervention for Solid Pancreatic Tumors

Abstract

Development and use of linear-array echoendoscope and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) have made endoscopic ultrasound (EUS) more of an interventional procedure than a purely diagnostic procedure. This is a literature review of previously published clinical studies on EUS-guided direct intervention for solid pancreatic tumors, including EUS-guided fine needle injection (EUS-FNI) of antitumor agents, EUS-guided fiducial marker placement, EUS-guided brachytherapy and EUS-guided tumor ablation.
