The presence of a cytopathologist increases the diagnostic accuracy of endoscopic ultrasound‐guided fine needle aspiration cytology for pancreatic adenocarcinoma: a meta‐analysis

Objective A meta‐analysis has not been previously performed to evaluate critically the diagnostic accuracy of endoscopic ultrasound‐guided fine needle aspiration ( EUS ‐ FNA ) of solely pancreatic ductal adenocarcinoma and address factors that have an impact on variability of accuracy. The aim of this study was to determine whether the presence of a cytopathologist, variability of the reference standard and other sources of heterogeneity...
