Randomized non‐inferiority trial comparing diagnostic yield of cytopathologist‐guided versus seven passes for endoscopic ultrasound‐guided fine‐needle aspiration of pancreatic masses

To improve diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in solid pancreatic lesions, on-site cytology review has been recommended. Because this is not widely available throughout the world, the aim of this study was to compare the diagnostic yield of EUS-FNA performed with rapid on-site evaluation (ROSE) versus 7 FNA passes without ROSE in pancreatic masses.In this multicenter randomized noninferiority trial,...
