The Diagnostic Utility of Real-Time EBUS-TBNA for Hilar and Mediastinal Lymph Nodes in Conventional TBNA Negative Patients

Background: There are many causes of mediastinal and hilar lymphadenopathy, such as neoplasms, granulomatous diseases, infections and reactive hyperplasia. Nowadays, the popularity of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is increasing in the diagnosis of mediastinal and hilar lymphadenopathy. We aimed to investigate the diagnostic value of EBUS-TBNA in patients with mediastinal and/or hilar lymphadenopathy and previously conventional TBNA-negative or inadequate results
