Description of the Test
To numb your throat, you may be given an anesthetic solution to gargle. Or, your throat may be sprayed with a numbing medication. You may be given a sedative through an IV. This is to help you relax during the test.
You may be asked to lie on your left side. You will have monitors tracking your breathing, heart rate, and blood oxygen levels. If sedation is used, you will be given supplemental oxygen to breathe through your nose.
A mouthpiece will be positioned to help keep your mouth open. During the test, a small suction tube will be used to clear saliva and fluids from your mouth. The endoscope will be lubricated and placed in your mouth. You will be asked to try to swallow it. Then, it will be carefully and slowly advanced down your throat. It will be passed through your esophagus and into your stomach and intestine.
While the endoscope is being advanced, your doctor will view the images on the screen. Air may be passed through the endoscope into your digestive tract. This will be done to smooth the normal folds in the tissues, allowing your doctor to view the tissue more easily. Tiny tools may be passed through the endoscope in order to take
or do other tests.
After the test, you will be observed for an hour. Then, you will be allowed to go home.
When you return home after the test, do the following to help ensure a smooth recovery:
- Rest when you get home.
- Ask your doctor if you can resume your normal diet. In most cases, you will be able to.
- Sedatives can slow your reaction time. Do not drive or use machinery for the rest of the day.
- Avoid alcohol for the rest of the day.
