Endobronchial Ultrasound (EBUS)

An endobronchial ultrasound (EBUS) is an examination of the lymph nodes surrounding the airways (bronchi). 

Thin, flexible scope

Your doctor will use a scope - a thin, flexible tube with a miniature camera at the tip, and an ultrasound machine. This scope will be inserted into the airways through your mouth and throat. You will be sedated during the procedure.

EBUS

What to expect

An EBUS - how does it work?

Your throat will be numbed and you will receive a sedative that will put you to sleep (propofol) or a muscle relaxant (midazolam) through IV. General anesthesia unfortunately is not an option as you will need to be able to breathe without assistance. We will numb your throat using a numbing spray. The spray can leave a bitter taste in the mouth.

Tissue sample

We will insert a ring into your mouth to keep your jaws open to allow for the insertion of the scope. The camera can give us a clear view of your airways while the ultrasound allows us to view the lymph nodes. If necessary, we can take tissue biopsies from the lymph nodes using a needle.

You will be asleep during the procedure and will not experience any discomfort.
