Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is useful for lung cancer diagnosis and lymph node staging. The purpose of this study was to investigate EBUS-TBNA for managing mediastinal and hilar lymphadenopathies without intrapulmonary masses. We retrospectively reviewed our EBUS-TBNA database that was obtained between August 2010 and October 2012. Mediastinal and hilar lymphadenopathies of unknown origin and in the absence of known pulmonary malignancies were included. Final diagnoses were determined by EBUS-TBNA, surgery, and/or clinical follow-up for at least 6 months. Sensitivity, specificity, accuracy, and positive and negative predictive values were determined using standard statistical methods. We identified 128 patients with mediastinal and hilar lymphadenopathies and without intrapulmonary masses. EBUS-TBNA was successfully performed to obtain samples from 161 lymph nodes and mediastinal masses. EBUS-TBNA was diagnostic for 119 of 128 patients (93.0%) for all disease categories. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of EBUS-TBNA were 89.8, 100, 100, 81.6, and 93.0%, respectively. The procedures were uneventful and there were no severe complications. EBUS-TBNA is a safe, minimally invasive approach for diagnosing mediastinal and hilar lymphadenopathies without intrapulmonary masses. It obviates the need for more invasive procedures for tissue sampling of the mediastinum and hilum.
