AIM: To compare the usefulness of endoscopic ultrasonography-guided fine-needle aspiration biopsy (EUS-FNAB) without cytology and mucosal cutting biopsy (MCB) in the histological diagnosis of @entity356 (SMT). METHODS: We prospectively compared the diagnostic yield, feasibility, and safety of EUS-FNAB and those of MCB based on endoscopic submucosal dissection. The cases of 20 consecutive @entity1 with gastric SMT >=  1 cm in diameter. who underwent both EUS-FNAB and MCB were investigated. RESULTS: The histological diagnoses were @entity674 (n = 7), @entity2909 (n = 6), @entity808 (n = 2), aberrant pancreas (n = 2), and one case each of @entity5 , metastatic @entity157 , and no-diagnosis. The @entity5 ' mean size was 23.6 mm. Histological diagnosis was made in 65.0% of the EUS-FNABs and 60.0% of the MCBs, a nonsignificant difference. There were no significant differences in the diagnostic yield concerning the @entity5 location or @entity5 size between the two methods. However, diagnostic specimens were significantly more frequently obtained in lesions with intraluminal growth than in those with extraluminal growth by the MCB method (P = 0.01). All four SMTs with extraluminal growth were diagnosed only by EUS-FNAB (P = 0.03). No complications were found in either method. CONCLUSION: MCB may be chosen as an alternative diagnostic modality in @entity5 showing the intraluminal growth pattern regardless of @entity5 size, whereas EUS-FNAB should be performed for SMTs with extraluminal growth.
