Background/Aims: Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose @entity1820 (SMTs). Although @entity3337 ( @entity3337 ) has been reported to improve the diagnostic accuracy of EUS-FNA for @entity660 , on-site cytopathologists are not routinely available. Given this background, the usefulness of @entity3337 by endosonographers themselves for @entity788 has also been reported. However, @entity3337 by endosonographers for diagnosis of SMT has not been reported. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with @entity3337 by endosonographers for SMT, focusing on diagnosis of @entity674 ( @entity674 ), compared with that of EUS-FNA alone. Methods: Twenty-two consecutive @entity1 who underwent EUS-FNA with @entity3337 by endosonographers for SMT followed by surgical resection were identified. Ten historical control subjects who underwent EUS-FNA without @entity3337 were used for comparison. Results: The overall diagnostic accuracy for SMT was significantly higher in cases with than without @entity3337 (100% vs. 80%, p=0.03). The number of needle passes by FNA with @entity3337 by endosonographers tended to be fewer, although accuracy was increased (3.3  1.3 vs. 5.9  3.8, p=0.06). Conclusions: @entity3337 by endosonographers during EUS-FNA for SMT is useful for definitive diagnosis, particularly for @entity674 .
