Endobronchial Ultrasound (EBUS)

What is it?

This is a method where abnormal lesions in the chest can be sampled without the need for invasive surgery.

Why is it done?

This test is usually done to diagnose or stage a lung cancer; however, this procedure may also be performed for a variety of other reasons.

Details of the procedure

  • EBUS can be done under sedation or a general anesthetic depending upon which one is most suitable for your situation
  • After you are drowsy or unconscious, a bronchoscope with an ultrasound probe is passed through your mouth into your airways
  • Once inside the airways, ultrasound images will be taken to identify and locate areas of interest
  • When the lesion is located, a needle will be passed into it and small samples taken
  • These samples will be sent for further testing in order to yield a diagnosis
  • This is a day procedure and you will be able to return home on the same day
