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.
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.
Methods
A retrospective analysis using data of patients referred to French-Brazilian Center of EUS of endoscopy Department of Santa Casa de São 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).
