Randomized crossover trial comparing <scp>EUS</scp>‐guided fine‐needle aspiration with <scp>EUS</scp>‐guided fine‐needle biopsy for gastric subepithelial tumors

Abstract

Both techniques were equivalently safe and successful in terms of a high diagnostic yield for gastric SET. And the tissue that can be immunohistochemically stained is present even in the specimens that appear to be a macroscopically bloody core.
