Endoscopic Ultrasound (EUS)

What is an EUS?

Endoscopic ultrasound is a minimally invasive imaging procedure that Dr. Ahmed performs. An endoscope is inserted into the mouth or rectum, and ultrasound is performed internally to image portions of the digestive tract and surrounding tissues and organs.

Why is an EUS done?

Ultrasound done from the inside of the body often obtains more accurate and detailed images than the images obtained from traditional ultrasound that is done through the abdominal wall. Endoscopic ultrasound is used to evaluate the biliary and pancreatic ducts, pancreas, blood vessels, and lymph nodes in patients with symptoms, abnormal blood work, or abnormal imaging. EUS is also used to diagnose and stage esophageal, pancreatic, gastric, colorectal, and bile duct cancers. Biopsy with fine needle aspiration can be performed using an EUS. In selected patients with pancreatic cancer or chronic pancreatitis, EUS can be used to inject medication to help with pain. 

How should I prepare for an EUS?

You will fast after midnight. If you are on blood thinners, our office will contact you to hold these prior to the procedure. You will need a driver home from the procedure.

What can I expect during an EUS?

You will be put to sleep with a moderate sedation. The procedure typically takes 10-45 minutes and is painless. If a rectal EUS is being performed, you will have to do an enema or take a laxative prior to the procedure.

What are the possible complications of EUS?

EUS is safe and complications are very rare. As with any endoscopic procedure, there is a risk of medication side effect, IV site discomfort, sore throat afterwards, aspiration, or perforation. If FNA is performed, there is a very small risk of bleeding, infection, or pancreatitis.
