Endobronchial ultrasound transbronchial needle aspiration in mediastinal and hilar lymphadenopathies.

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