Comparing EUS-Fine Needle Aspiration and EUS-Fine Needle Biopsy for Solid Lesions: A Multicenter, Randomized Trial

Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the GI tract. Fine needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB.
