Endoscopic Ultrasound

What is Endoscopic ultrasound (EUS)?
EUS is a minimally invasive endoscopic procedure that allows the doctor to see detailed images of the esophagus, stomach, pancreas, bile ducts or rectum to provide additional information obtained from CT or MRI. An EUS can also be used for taking samples of abnormal tissue using a fine needle.

How is EUS performed?
A thin, flexible tube (endoscope) is passed through the mouth and into the stomach and duodenum or through the rectum. The endoscopes ultrasound probe emits sound waves that pass through the lining of the GI tract, creating an image of the bowel or adjacent organs.

What can I expect from the EUS procedure?
EUS is performed on an outpatient basis; you will be sedated and not allowed to drive after the procedure. It takes about 30 to 45 minutes and recovery time is another 40 minutes.

What are the possible complications associated with EUS?
EUS is a very safe procedure and although complications occur, they are rare when doctors with specialized training and experience perform the EUS examination. You may have a sore throat, which usually resolves within a day or two.
Consult your doctor for all the risks associated with the EUS procedure.
