Conventional versus Ultrasound-Guided Transbronchial Needle Aspiration for the Diagnosis of Hilar/Mediastinal Lymph Adenopathies: A Randomized Controlled Trial

Conventional transbronchial needle aspiration (c-TBNA) and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are both valuable diagnostic techniques for the diagnosis of hilar/mediastinal lesions. Although a superiority of EBUS-TBNA over c-TBNA may be expected, evidence-based data on a direct comparison between these 2 procedures are still lacking.We aimed to test the superiority of EBUS-TBNA over c-TBNA in a...
