Endoscopic Ultrasound (EUS)

An endoscopic ultrasound (EUS) is an examination the lining and the walls of the upper or lower gastrointestinal tract. The upper tract is the esophagus, stomach, and duodenum; the lower tract includes your colon and rectum. EUS allows us to look deep to the inside lining of the gastrointestinal tract rather than just at the surface. EUS is also used to study internal organs that lie next to the gastrointestinal tract, such as the gallbladder, bile ducts, and pancreas. The doctor will pass a thin, flexible tube called an endoscope through your mouth or anus to the area to be examined.
