Endoscopic Ultrasound

You have been referred to have an endoscopic ultrasound, or EUS, which will help your doctor evaluate or treat your condition.


What is EUS?

 EUS is a procedure that utilizes high-frequency ultrasound during endoscopy to image the gastrointestinal (GI) tract and surrounding structures.  EUS provides detailed images and allows passage of a needle into a suspected tumor to obtain tissue samples.  This is a type of biopsy is called fine-needle aspiration.  Cells obtained from the biopsy can then be analyzed to see if they are cancerous and can help in deciding the best course of treatment.


Why is EUS used for cancer patients?

EUS helps your doctor determine the extent of certain cancers of the digestive and respiratory system.  EUS allows your doctor to accurately assess the cancer’s depth and whether it has spread to adjacent lymph glands.  EUS is the most accurate imaging test available for the local and regional staging of esophageal, gastric, rectal and pancreatic cancer.


How do you prepare for EUS?

For EUS of the upper GI tract, an empty stomach allows for the best and safest examination, so you should have nothing to eat or drink, including water, for approximately 12 hours before the examination.  Your doctor will tell you when to start fasting.

Follow our Upper Endoscopy Prep instructions.

For EUS of the rectum or colon, you may be asked to use enemas to cleanse the rectum.


What should you expect on the day of your EUS?

After you check in, a nurse will meet with you to review you medical conditions and medications.  An IV line will be placed in a vein in your arm.  You will proceed to the procedure room, where your blood pressure, pulse and oxygen level will be carefully monitored.  A sedative will also be administered through your IV, and you may need general anesthesia. 

During EUS, the patient lies on his/her side and the doctor passes a thin, flexible tube called an echoendoscope through your mouth or anus to the area to be examined.  Once in place, the ultrasound probe at the end of the endoscope uses sound waves to create images of the gastrointestinal tract and surrounding structures.

Usually, the EUS procedure lasts 15-45 minutes.  After the test, you will rest until the effects of the medicine wear off.  You will not be able to drive following the procedure, so plan on having someone with you to take you home.  Your doctor generally can inform you of the results of the procedure that day, but the results of some tests may take several days.  If you were referred to our office by another physician for this procedure, you will receive your results from that physician.
