Endoscopic Ultrasound (EUS)

Endoscopic ultrasound (EUS) is a minimally invasive procedure to assess the gastrointestinal tract for diseases. A special endoscope uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and nearby organs such as the pancreas, liver and the lymph nodes as well. When combined with fine-needle aspiration, biopsies can also be performed for further analysis.

How is it performed?

Before the procedure, the patient might be sedated.
The doctor passes a thin, flexible tube through the mouth and into the digestive tract.
A small ultrasound device (transducer) in the tube produces sound waves that create a precise image of surrounding tissues.
If fine-needle aspiration is being done, the doctor may pass a second device through a channel in the endoscope to the site.
The device can guide a slender needle to the lymph nodes, tumours or other abnormalities. The needle extracts the required fluid and/or tissue for analysis.
The endoscope is then gradually withdrawn.
