Materials and Methods: This is a single-center, retrospective study. Results: Among 22 patients who underwent EUS-FNA, a cytopathological diagnosis was reached in 16 (72.7%) patients. The EUS-FNA results were as follows: seven GISTs (31.8%), six leiomyomas (27.2%), four non-diagnostics (18%), two duplication cysts (9%), two spindle cell tumor (9%), and one ectopic pancreas (4.5%). The long-axis size was &amp;gt;20 mm in 12 patients (average size: 31.3 &amp;plusmn;9.3 mm) and &amp;lt;20 mm (average size: 16.6 &amp;plusmn;2.5 mm) in 10 patients. Diagnostic accuracy of EUS-FNA from lesions &amp;lt;20 mm was 50% (5\/10 lesions), and of lesions &amp;gt;20 mm was 91.6% (11\/12 lesions) (Fisher&amp;rsquo;s exact test; p=0.028). Six patients underwent surgical resection. Surgical pathology results of five lesions (four GIST, one leiomyoma) were consistent with cytopathology results (83.3%). Conclusion: The diagnostic yield of EUS-FNA of the upper GI SELs with an onsite cytopathologic interpretation was 72.7%. Lesion size &amp;lt;2 cm significantly reduces the diagnostic yield of EUS-FNA for the upper GI SELs. Cite this article as: Attila T, Ayd\u0131n &amp;Ouml;.
