What is an unsedated transnasal endoscopy?

Path of the cameraIt is a procedure that helps your doctor to learn what is going on inside your body. Your doctor will use a thin and flexible tube. It has a camera with a light at the end of it. The tube will go into your nose, down your throat, and food pipe (esophagus), sometimes to your stomach and small intestine. This is a TNE-EGD. This tube allows the doctor to see inside your body and collect small samples, called biopsies. They are the size of a pinhead. It will help check the health of the areas. Your child will be awake and alert for this procedure.

How to prepare for the procedure?

What happens on the day of the test?

How is TNE done?

As the doctor begins to put the tube in your nose, it may tickle. You might feel like you need to sneeze. Sometimes your eyes may water. When the tube reaches the back of your throat, you will be asked to swallow to help the tube go down. Remember to keep taking deep breaths.

The doctor will take biopsies of your esophagus. Most kids don’t feel this. If they do, it might feel like a small pinch. When the doctor is all done, the tube will slowly be taken out of your nose. Before you leave, the doctor will talk to you and your caregiver.

The procedure takes 5 to 15 minutes. You may be in the office for about one hour.

What to expect after the procedure

Your throat may still feel a bit lumpy or be sore for a little while.

When will I know the results?

The doctor will tell you the results once the procedure is done. The results of the biopsies will be ready in about 1 week.
