EBUS stands for Endobronchial ultrasound, a respiratory abbreviation.
Bronchoscopy technique using an ultrasound probe on the bronchoscope tip to see and sample lymph nodes and masses next to the airways, usually by transbronchial needle aspiration (EBUS-TBNA). It is a key tool for diagnosing and staging lung cancer.
Example: EBUS-TBNA of station 7 and 4R nodes: 4R positive for adenocarcinoma, stage IIIA.
Usage notes
EBUS offers a minimally invasive alternative to surgical mediastinoscopy for staging the mediastinum, usually under moderate sedation or general anesthesia as an outpatient. Samples can be tested for molecular markers and PD-L1 to guide targeted therapy and immunotherapy. It also diagnoses sarcoidosis and lymphoma. Pronounced "EE-bus."
