EUS-guided tissue acquisition with rapid on-site cytologic evaluation (ROSE) has been used to increase the diagnostic yield. However, ROSE is not available in many centers. To date, only a few studies have assessed the adequacy of histologic cores in macroscopic on-site evaluation (MOSE) during EUS-guided fine-needle biopsy (EUS-FNB). Blood contamination of histologic core specimens lowers the sample quality and the diagnostic yield. Therefore, we evaluated the efficacy of MOSE using filter paper to increase the adequacy of histologic core specimens while minimizing blood contamination.
