Endoscopic ultrasound‐guided tissue acquisition of solid mass lesions of the pancreas: A retrospective comparison study of fine‐needle aspiration and fine‐needle biopsy

Background Although endoscopic ultrasound guided fine‐needle biopsy (EUS‐FNB) has emerged as an alternative to fine‐needle aspiration (FNA) for the sampling of solid pancreatic mass lesions, it remains unclear which method is more effective. We compared the diagnostic yields of FNA, FNB, and combined FNA/FNB at a tertiary care institution. Methods Specimens from EUS‐FNA (04/2014‐08/2017) and EUS‐FNB (10/2015‐08/2017) with SharkCore needle of...
