What is an endoscopic ultrasound (EUS)?
An EUS (endoscopic ultrasound) is an endoscopic procedure where a GI specialist inserts a thin scope through the mouth and into the small intestine or rectum. The scope, which has a light and camera on it, helps the provider examine the esophagus, stomach, the first portion of the small intestine, and/or the rectum. Additionally, the scope has an ultrasound probe, allowing the provider to directly look at the different layers of the intestinal wall and other organs. If necessary, a fine-needle aspiration and biopsy can be taken. An EUS is often performed to detect abnormalities in the intestinal wall or organs such as the pancreas, biliary system, and chest, or to determine cancer stages. If you’ve been experiencing discomfort or other symptoms related to your GI tract, an EUS at GI Alliance of Illinois can help you find the relief you need.

Why would I need an EUS?
There are a number of reasons why your GI Alliance of Illinois provider would suggest an endoscopic ultrasound, including to:
- Evaluate tumors or abnormalities in the gallbladder, liver, and more
- Study nodules in the intestinal wall
- Evaluate stages of cancer
- Assess Barrett’s esophagus
- Evaluate pancreatic or biliary disorders
What are the risks of an endoscopic ultrasound?
EUS procedures are typically very safe. Generally, complications occur in less than 1 percent of cases and they are often non-life-threatening. There are times, however, in the rare case a complication does occur, that hospitalization or surgery may be necessary. Prior to your exam, we will have you review and sign a consent form regarding this information, so you can ask any questions or bring up any concerns you may have at that time.
It is also possible to have a reaction to the sedation. This can include allergic reactions, difficulty breathing, blood pressure issues, irritation of the vein, and more.
In very rare cases, fine-needle aspiration and biopsies can lead to bleeding. It’s unlikely, but if significant bleeding occurs, hospitalization or a blood transfusion may be necessary.
It is very important that the patient contact the doctor’s office immediately if symptoms arise after the procedure such as worsening abdominal pain, bleeding, or fever.
