Introduction: The endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has emerged as a minimally invasive and safe method for material procurement in the differential diagnosis of subepithelial lesions (SEL) of upper gastrointestinal tract (UGT), especially in suspicious lesions of gastrointestinal stromal tumors (GIST). There are few studies discussing the factors that influence the EUS-FNA in the diagnosis of SEL.

Aim: To establish possible associations between lesion size, layer and organ of origin with the outcome of EUS-FNA in patients with SELs of UGT.

Methods: A retrospective analysis using data of patients referred to French-Brazilian Center of EUS of endoscopy Department of Santa Casa de Sγo Paulo Hospital, with previous endoscopic diagnosis of SEL, which underwent EUS-FNA from May 2006 to August 2011.

Results: A total of 222 patients were submitted to EUS. 15 with extrinsic compressions and 207 with SEL. Of these, 89 underwent to EUS-FNA. Ninety-two SEL were diagnosed on EUS and punctured. The EUS-FNA was positive in 58.7%. In lesions measuring 2-3 cm and >3 cm, the EUS-FNA was positive in 80% and 72%, respectively (P < 0.001).

Conclusion: The size of SELs was the only variable that influenced the outcome of EUS-FNA. Best results are achieved in lesions larger than 2 cm.
