Endobronchial ultrasound bronchoscopy (EBUS) is a minimally invasive and widely utilized endoscopic technique that enables real-time ultrasound visualization of mediastinal and hilar lymph nodes adjacent to the tracheobronchial tree, allowing tissue sampling under direct sonographic guidance. Accessible nodal stations include 1, 2R/L, 3P, 4R/L, 7, 10R/L, and 11R/L; however, stations 5 and 6 are technically more challenging and associated with a higher risk of complications due to their proximity to the aorta and pulmonary vessels.
EBUS can be used for diagnostic, staging, and restaging purposes, particularly in conditions such as lymphoma and sarcoidosis, as demonstrated in the accompanying video. Its diagnostic yield varies according to the underlying pathology and nodal characteristics, and the diagnostic sensitivity for specific diseases is outlined below.
