Endoscopic ultrasound-guided fine-needle aspiration of solid pancreatic masses with rapid on-site cytological evaluation by endosonographers without attendance of cytopathologists

摘要

Background Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with rapid on-site evaluation (ROSE) has been reported to provide a more accurate diagnosis than EUS-FNA without such evaluation. However, even endosonographers can evaluate ROSE regarding sample adequacy. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with ROSE by endosonographers compared to ROSE by cytopathologists in patients with solid pancreatic masses.
