EBUS-TBNA stands for Endobronchial Ultrasound-guided Transbronchial Needle Aspiration. It combines bronchoscopy with ultrasound imaging to examine and sample lymph nodes and masses in the centre of the chest (mediastinum).
Why is it done?
- To diagnose and stage lung cancer
- To investigate enlarged lymph nodes
- To diagnose tuberculosis or sarcoidosis affecting lymph nodes
How it works
A special bronchoscope with a small ultrasound probe at its tip is passed through the mouth. The ultrasound shows structures beyond the airway wall, including lymph nodes and blood vessels. A fine needle is then passed through the airway wall into the target under real-time ultrasound guidance to collect cells.
Because it is minimally invasive, EBUS-TBNA can often avoid the need for surgical procedures to obtain tissue.
