Endoscopic Ultrasound

Back to All Services

Endoscopic Ultrasound (EUS)- combines Endoscopy (EGD) and ultrasound, a long flexible endoscope is inserted through the mouth, down the esophagus, into the stomach, and through a small portion of the duodenum. The ultrasound (high frequency sound waves that produce images) enhances the depth of the skin tissue, muscle tissue, lymph nodes, blood vessels, and outlines structures inside the body, such as gallbladder, pancreas, liver, etc. A EUS also allows your physician to obtain tissue samples by passing a needle through the endoscope into enlarged masses, and suspicious tumors. This procedure is called a fine needle aspiration (FNA).

An EUS is suggested for the following situations:

  • Determining the stage of Esophageal, Stomach, Pancreatic, Rectal Cancer
  • Evaluating pancreatitis
  • Evaluating the Gall Bladder, Liver, Bile Ducts
  • Evaluating the reasons for fecal inconsistency
  • Evaluating other submucosal lesions, bumps, masses, etc that may be hiding behind normal appearing intestinal walls.

To prepare for a EUS, one must not each from 12 midnight, and not drink 4 hours before the procedure. Plan for your care and recovery after the operation. Allow for time to rest and try to find people to help you with your day-to-day duties.

Follow any instructions your doctor may give you.

Once you are awake after the procedure, the doctor will discuss with you, your results. Someone should be available to accompany you home. Light meals and fluids are allowed unless otherwise instructed.

Complications from EUS are rare. They include: irritation of vein used to administer sedatives or medication, reaction to sedative or medication administered, complications resulting from pre-existing heart/lung/liver conditions, bleeding at site or biopsy or polyp removal (bleeding would be minimal and rarely requires surgery or transfusion), or perforation (which is also very rare, but would require surgery to repair). Be sure to discuss any pre-existing medical conditions or health concerns with your physician before the procedure in order to reduce complications.
