    ObjectiveTo compare the values of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and TBNA for the diagnosis of hilar and mediastinal lesions.MethodsThe clinical data of 100 patients who underwent EBUS-TBNA (n=50) and TBNA (n=50) between January 2010 and May 2011 were retrospectively reviewed, and the results and complications were recorded.ResultsA total of 121 lesions in the 100 patients were evaluated, the sample yeilds of EBUS-TBNA and TBNA were 90.6% and 78.9% and the diagnostic accuracy rates in the two groups were 90.0% and 72.0%(P=0.022), respectively. No major complications happened. The sensitivity, specificity and accuracy of EBUS-TBNA were higher and the complication rate was not increased as compared with TBNA.ConclusionEBUS-TBNA has a higher diagnostic yield for the evaluation of hilar and mediastinal lesions.
