Histopathological comparison of aspiration and biopsy needles in endoscopic ultrasound‐guided tissue acquisition in patients with subepithelial lesions
Abstract:BackgroundInformation on whether a fine‐needle biopsy (FNB) needle can improve histopathological specimen quality or the amount of core tissue collected in the diagnosis of subepithelial lesions (SELs) remains insufficient. In this study, we aimed to compare the procedure outcomes and adequacy of histopathological specimens of fine‐needle aspiration (FNA) and FNB needles in endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) using sample isolation processing by stereomicroscopy (SIPS) in patients with SEL… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
