Macroscopic on-Site Evaluation (MOSE) of Acquired Specimens Of Solid Lesions During EUS-FNB: A Multicenter Study and a Comparison Between Needles Gauge

Aims The standard methods to obtain sampling during endoscopic ultrasonography (EUS) is the fine needle aspiration (FNA) which could be affected by the presence of cytopathologist in endoscopy room (ROSE). With the introduction of fine needle biopsy (FNB), the macroscopic on-site evaluation (MOSE) of the acquired specimen was proposed. Few studies are published about this issue and in all, except one, a 19G needle was used, influencing the...
