About Your Endoscopic Ultrasound (EUS)

This information explains your endoscopic ultrasound (EUS) at Memorial Sloan Kettering (MSK).

An EUS is a procedure that uses sound waves to show images of your internal organs. It will give your doctor information about:

• How deep a tumor extends into your tissue.
• If your lymph nodes are enlarged.
• If there is a tumor in nearby tissues.
• How a tumor has responded to cancer treatment.

During your EUS, your doctor may also do a biopsy procedure to take a sample of tissue with a needle. If you have cysts, your doctor may also use a needle to remove fluid to learn more information about it and understand what is making it grow.

Your EUS will be done as part of another endoscopy procedure you’re having. To prepare for your EUS, review the information that your nurse gave you about the endoscopy procedure you’re having.

• If you’re scheduled to have an EUS of the upper part of your digestive system, such as your esophagus (food pipe), stomach, or pancreas, follow the instructions in the resource About Your Upper Endoscopy (www.mskcc.org/pe/upper_endoscopy).
• If you’re scheduled to have an EUS of your rectum or colon (large intestine), follow the instructions in the resource that your doctor or nurse gave you, which may be:
  • About Your Flexible Sigmoidoscopy (www.mskcc.org/pe/flexible_sigmoidoscopy)
  • How to Prepare for Your Colonoscopy Using MiraLAX® (www.mskcc.org/pe/colonoscopy_miralax)
