Endoscopic Ultrasound

What is Endoscopic Ultrasound?
Endoscopic ultrasonography (EUS) allows your doctor to examine your esophageal and stomach linings as well as the walls of your upper and lower gastrointestinal tract.  EUS is also used to study other organs that are near the gastrointestinal tract, including the lungs, liver, gall bladder and pancreas.

Your endoscopist will use a thin, flexible tube called an endoscope that has a built-in miniature ultrasound probe.  Your doctor will pass the endoscope through your mouth or anus to the area to be examined.  Your doctor then will use sound waves to create visual images of the digestive tract.

Why is EUS done?
EUS provides your doctor with more information than other imaging tests by providing detailed images of your digestive tract, to evaluate certain lumps or lesions with detailed imaging, and to diagnose diseases of the pancreas, bile duct and gall bladder when other tests are inconclusive or conflicting.
