摘　　要：To the Editor:Endoscopic ultrasound-guided fine needle aspiration(EUS-FNA)has replaced other high-risk invasive methods and has become the primary method of tissue collection around the gastrointestinal tract.^([1])To further improve the effectiveness and safety of EUS-FNA,pathologists may perform rapid on-site cytology evaluation(ROSE),but this process requires the presence of pathologists.Macroscopic on-site evaluation(MOSE)has gained attention as it resolve the shortage of pathologist resources.^([2])Endoscopists can inspect the tissue core in real time and assess the adequacy of the punctured material.In this study,we conducted a single-center and single-arm exploratory study to explore the value of MOSE in assessing specimen quality during magnifier-based EUS-FNA and to confirm the cut-off length of visible tissue core(VTC)for EUS-FNA to help endosonographers independently predict the adequacy of punctured specimens.The VTC was defined as a white or incarnadine tissue core obtained from focal lesions with a relatively complete histological structure.
