Flexible Bronchoscopy in the Evaluation of Mediastinal and Hilar Lymphadenopathy

摘要

BackgroundThe diagnosis in cases of mediastinal and/or hilar lymphadenopathy with no lung parenchymal involvement is often difficult. We undertook this study to assess the diagnostic value of flexible bronchoscopy (FOB) especially transbronchial needle aspiration (TBNA) and transbronchial lung biopsy (TBLB) in these patients.
