Abstract:
Transbronchial needle aspiration (TBNA) is an effective, safe and cost-effective technique that allows for sampling of the mediastinal lymph node and peribronchial lesions. It is used in bronchogenic carcinoma staging, peribronchial and submucosal lesions, diagnosis of sarcoidosis and tuberculosis, differentiating submucosal invasion, and in diagnosing mediastinal masses. From our experience at the University of Abant Izzet Baysal and from a review of the literature, we discuss the adequacy and the differential diagnosis of aspiration material obtained by TBNA and cytopathological-histopathological evaluation in intrathoracic lymphadenopathies to increase the success rate of the TBNA method.
