Macroscopic on-site evaluation after EUS-guided fine needle biopsy may replace rapid on-site evaluation

Rapid on-site cytologic evaluation (ROSE) increases the diagnostic yield of EUS-FNA. However, ROSE requires the presence of a cytopathologist and additional cost and time for slide staining and interpretation. Macroscopic on-site examination (MOSE) was recently introduced as an alternative to ROSE and showed high accuracy for the use in pathologic diagnosis. We evaluated the efficacy of MOSE in terms of tissue acquisition and diagnostic accuracy...
