Prospective Assessment of the Performance of a New Fine Needle Biopsy Device For EUS-Guided Sampling of Solid Lesions

Introduction: Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) remains the most common EUS guided tissue acquisition technique. However, its reported sensitivities range from 70% to 90%. This study aims to evaluate the overall performance of a new fine needle biopsy (FNB) device in EUS sampling of solid lesions by assessing the cytologic and histologic yield of the FNB samples compared to FNA samples (controls). Methods: Consecutive...
