Endoscopic Ultrasound (EUS) Q & A

What is an endoscopic ultrasound (EUS)?

An EUS is a procedure that merges endoscopy and ultrasound. 


In an endoscopy, a thin scope (a long tube) that houses a light and tiny camera sends images from within your digestive tract to a monitor where your provider can examine them in detail. An upper endoscopy examines and (sometimes treats) the upper digestive tract (esophagus, stomach, and the start of the small intestine), while a lower endoscopy covers the large intestine area.


An ultrasound uses sound waves to produce images of your inner body. Using ultrasound technology, your provider can get an in-depth projection of your digestive tract and the organs around it.

An endoscopic ultrasound is a safe minimally invasive way to evaluate problems and get answers regarding troublesome digestive issues. 

When might I need an endoscopic ultrasound (EUS)?

You might need an upper endoscopic ultrasound if you’re experiencing unexplained abdominal or chest pain. An upper endoscopic ultrasound allows your provider to closely examine the bile ducts, gallbladder, pancreas, and liver to detect problems such as small pancreatic tumors and stones in the bile ducts.

A lower endoscopic ultrasound can help to detect the reason for fecal incontinence or other large intestine-related issues, or it can examine previously-detected lesions or tumors.

In addition, doctors use endoscopic ultrasound to determine the severity (staging) of gastrointestinal cancers. As part of cancer staging, your provider may perform a fine-needle aspiration biopsy, in which they insert a slim needle through the endoscope to gather tissue samples.

The American Gastroenterological Association says that doctors are also developing new uses for endoscopic ultrasound. 

How do I prepare for an endoscopic ultrasound (EUS)?

Michiana Gastroenterology, Inc gives you preparation instructions before your upper or lower endoscopic ultrasound. For upper EUS, you’ll need to fast prior to the procedure. 

For lower EUS, you’ll need to follow a preparation protocol similar to that of a colonoscopy to clean out your large intestine prior to the procedure.  

Additionally, your medical provider at Michiana Gastroenterology, Inc discusses all of your medications with you before your EUS. You may need to temporarily stop some of those medications.
