It is used to see organs in and near the digestive tract. How the Test is Performed Ultrasound is a way to see the inside of the body using high-frequency sound waves. Endoscopic ultrasound does this with a thin, flexible tube called an endoscope.This tube is passed either through the mouth or through the rectum and into the digestive tract. Sound waves are sent out the end of the tube and bounce off the organs in the body. A computer receives these waves and uses them to create a picture of what is inside. This test does not expose you to harmful radiation. If a sample or biopsy is needed, a thin needle can be passed through the tube to collect fluid or tissue. This does not hurt.The test takes 30 to 90 minutes to complete. Often you will be given medicine to help you relax. How to Prepare for the Test Your health care provider will tell you what to do. You will be told when to stop drinking and eating before the test.Give your provider a list of all the medicines you take (prescription and over-the-counter), herbs, and supplements. You will be told when you can take these. Some need to be stopped a week before the test. Ask your provider which medicines you should take on the morning of surgery. Since you will not be able to drive or return to work on the day of this test, you will need someone to take you home. How the Test will Feel Before this test you will get medicine through an IV to help you relax (a sedative). You may fall asleep or not remember the test. Some people feel the test is slightly uncomfortable.For the first hour after this test, you may feel sleepy and unable to drink or walk. You may have a sore throat. Air or carbon dioxide gas may have been put in your digestive tract during the test to move the tube more easily. This may make you feel bloated, but this feeling will go away.When you are fully awake, you can be taken home. Rest that day. You may have fluids and light meals.
