Endoscopic Ultrasound

What is it?

Endoscopic ultrasound allows a doctor to capture ultrasound images of the digestive system from inside the body. An ultrasound device is inserted into the body using an endoscope, a long, flexible tube with a tiny light and camera. The endoscope allows the doctor to position the ultrasound device in a precise location to get an image of a small, specific area.

Who needs it?

Endoscopic ultrasound may be used to diagnose, treat, or measure the progress of several digestive system diseases. The test can also provide information about the lining of digestive organs, something most other tests aren’t able to do.

Endoscopic ultrasound is often used to explore the extent of cancers of the esophagus, stomach, pancreas, and rectum, so exploratory surgery won't be needed. Endoscopic ultrasound is also useful in evaluating chronic pancreatitis, as well as studying bile duct abnormalities and muscles in the lower rectum.

An endoscopic ultrasound must be ordered by a physician.
