What is endoscopic ultrasonography (EUS) used for?

Your doctor can use endoscopic ultrasound (EUS)—a medical procedure to examine the lining and the walls of the upper and lower gastrointestinal tract—to diagnose the cause of conditions such as abdominal pain or abnormal weight loss. Or, if your doctor has ruled out certain conditions, EUS can confirm your diagnosis and give you a clean bill of health.

EUS can be used to evaluate an abnormality, such as a growth, that was detected during a prior endoscopy, colonoscopy, or x-ray. EUS provides a detailed picture of the growth, which can help your doctor determine its nature and decide upon the best treatment. EUS also can be used to diagnose diseases of the pancreas, bile duct, and gallbladder when other tests are inconclusive.

Endoscopic ultrasounds are used to diagnose many conditions, including pancreatic, common bile duct, and lung and stomach conditions.
