Endoscopic Ultrasound (EUS)

Endoscopic ultrasound (EUS) is a procedure that uses a specialized endoscope with high frequency sound waves to obtain detailed imaging of the lining of the gastrointestinal tract and surrounding organs, including the liver, pancreas, bile duct, gallbladder and lymph noes. It also allows your doctor to obtain tissue samples from the inside using a small needle, without requiring surgery. 

EUS can also be used to drain fluid from pancreatic cysts, abscesses, bile ducts and the gallbladder.

Who Might Benefit from an EUS?

You might need an endoscopic ultrasound to diagnose or evaluate the progression of certain cancers, including the following:

• Esophageal cancer
• Lung cancer

Your doctor also might recommend an EUS if you have one of the following conditions:

• Nodules or polyps that may become cancer
