Gross visual inspection by endosonographers during endoscopic ultrasound-guided fine needle aspiration

A clear criterion for terminating endoscopic ultrasound fine needle aspiration (EUS-FNA) without rapid on-site evaluation (ROSE) has not been established. However, a possible solution includes gross visual inspection (GVI) of the sample obtained with EUS-FNA. We performed a retrospective study to elucidate the efficacy of GVI for the diagnostic yield of EUS-FNA. Patients who underwent EUS-FNA of a pancreatic mass using a standard 22-G needle...
