Comparison between fine-needle biopsy and fine-needle aspiration for EUS-guided sampling of subepithelial lesions

On By GIEjournalIn GIE, InvestigationsLeave a comment

Post written by Antonio Facciorusso, MD, PhD, from the Gastroenterology Unit, University of Foggia, Foggia, Italy. Endoscopic ultrasound (EUS) fine-needle aspiration (FNA) did not prove to outperform bite-on-bite biopsy in patients with subepithelial lesions (SELs) showing a pooled diagnostic yield as high as 60%. Based on this evidence, current guidelines recommend EUS-guided sampling only in …
