An Endoscopic Ultrasonography or EUS, is a diagnostic test your doctor will use to investigate areas of concern in your digestive tract. The test can also be used to create visual images of organs located near the GI tract. The specialists at Concorde Gastroenterology are trained, skilled professionals with extensive training and experience performing an EUS.

An EUS can be used to examine the upper portion of your digestive tract, including your stomach, esophagus, and duodenum (the upper portion of your small intestine); or the lower portion including your colon and rectum. Other organs can also be studied with an EUS including the pancreas, gallbladder, liver, and lungs. During the procedure the doctor will insert a thin, flexible endoscope that is equipped with miniature ultrasound probe. This probe uses sound waves to form an image allowing for better diagnosis or evaluation of a known condition.

Why would your doctor order an EUS?

  • Diagnosis – abdominal pain, unexplained weight loss are some of the symptoms that should be addressed with your doctor and may require an EUS to achieve a correct diagnosis. It is also useful to diagnosis diseases of the pancreas, gallbladder, and bile ducts when other testing has been inconclusive.
  • Evaluation – when a lump or lesion is found during another test or X-ray, your doctor may order an EUS to get a closer look and determine the correct course of treatment. When needed an EUS can be used to obtain a biopsy for testing.
  • Cancer – an EUS allows doctors to track certain cancers accessing the depth of tissue involvement and spread of the cancers to lymph nodes or surrounding areas.

The preparation for an EUS depends on type (upper or lower) and your doctor will provide detailed instructions for you to follow. Make sure to talk to your Concorde Gastro physician about all medications you take, both prescription and over the counter. Also discuss any allergies you have and your medical history.

Your EUS procedure orders will include information about sedation. If you have anesthesia you will need to have a companion/driver to accompany you home and stay with you while you complete your recovery.
