Endoscopic ultrasound (or EUS) combines two procedures, upper endoscopy (or EGD) and ultrasound, to create detailed images of your upper digestive tract and the surrounding organs and tissues.
Upper endoscopy uses a long, thin, flexible tube with a camera attached to it, inserted into your mouth, esophagus, stomach, and small intestine, to see inside your upper GI tract. Ultrasound uses sound waves to create images of the inside of your body. The combination of both procedures provides detailed images of your digestive tract.
You are sedated for the procedure. It takes roughly 1-2 hours to complete and is performed at the medical center.
EUS is used to detect small tumors in the pancreas, to evaluate other pancreatic conditions such as pancreatic pseudocyst and chronic pancreatitis, to stage gastrointestinal cancers, to detect stones in the biliary ducts, to diagnosis problems in the bile ducts and gallbladder, to evaluate nodules, and to characterize lesions or bumps in the walls of the intestine found on other tests such as CT, MRI or EGD.
