Answer

Endobronchial ultrasonography (EBUS) has been widely adopted by pulmonologists and thoracic surgeons and is poised to replace mediastinoscopy in the future. For thoracic surgeons, the technique can be easily learned, and it may be important to do so to maintain its traditional and important role in the diagnosis and staging of thoracic malignancies.

EBUS has been associated with a low (< 1%) rate of serious adverse effects, and the procedure is touted as being highly accurate, with reported false-negative rates in the range of 6-9%. The aforementioned study by Ost et al found radial EBUS to have a lower-than-expected yield in patients with peripheral lung lesions. [25]

EBUS-guided fine-needle aspiration (FNA) biopsy of mediastinal nodes offers a less invasive alternative for histologic sampling of the mediastinal nodes.
