What is a EUS?

Endoscopic ultrasonography (EUS) is procedure where an ultrasound probe is at the tip of an endoscope. This allows examination of 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. A needle can be inserted through the scope that allows material to be collected for pathological analysis from the linings of the upper GI tract or organs just outside the upper GI tract.
