Abstract
Endobronchial ultrasound (EBUS)-transbronchial needle aspiration (TBNA) is a relatively noninvasive technique that allows sampling of mediastinal and hilar lymph nodes or masses under real-time and direct visualization, overcoming some of the problems associated with mediastinoscopy and blind TBNA. The goal of this study was to evaluate the yield of this technique in patients with and without malignant disease in a newly started EBUS program involving physicians not previously fully trained in interventional pulmonology. Between March 2010 and July 2011, 43 patients with enlarged lymph nodes (>1 cm on short axis) on chest computed tomography who underwent EBUS-TBNA were included in the study. Nondiagnostic results were confirmed with mediastinoscopy. The sensitivity, specificity, positive predictive value and negative predictive value of the technique were assessed. Among the 43 patients who underwent EBUS-TBNA, a correct diagnosis was made in 39 of the 43 patients (91%). The sensitivity, specificity, positive predictive value, and negative predictive values were 89%, 100%, 100%, and 67%, respectively. The success rate, complication rate, and 30-day mortality were 91%, 0%, and 0%, respectively. EBUS-TBNA is a safe and effective approach with high diagnostic yield and minimal complications for diagnosing and staging of mediastinal/hilar lymph nodes. Satisfactory results can be obtained immediately by pulmonologists experienced in conventional bronchoscopy with the provision of additional training on the technique.

      Background and objective: To investigate the sensitivity and specificity of transbronchial needle aspiration (TBNA) for restaging the mediastinum after neoadjuvant chemotherapy. Methods: Twenty-one consecutive patients with pathological stage IIIA-N2 disease were treated with neoadjuvant chemotherapy. TBNA was applied to restage a"er chemotherapy. Based on chest computed tomography comparison,... [Show full abstract]
