All About Upper Endoscopy (Panendoscopy): Preparation and Procedure
What to expect before, during and after your procedure.
Your comfort is important to us. When you arrive for your procedure, we want you to know exactly what to expect.
Upper endoscopy, also known as panendoscopy, is a visual examination of the lining of the esophagus, stomach and upper section of the small intestine using a flexible tube with a miniature lighted camera, known as a fiber-optic endoscope.
How to prepare for your procedure.
You should follow your doctor's specific preparation instructions, which may include:
- You should have nothing to eat or drink six to 12 hours before the procedure
- You may be asked to arrive one hour prior to your scheduled procedure
How the procedure works.
Before your exam begins, an intravenous (IV) line will be placed in your arm to deliver medications for comfort during the procedure. We will continually check your blood pressure, heart rate and oxygen via a monitor.
The endoscope will be inserted through your mouth, and a small plastic mouthpiece will be placed between your teeth. Dentures, tongue rings, partials and other items will need to be removed from your mouth.
For the duration of your procedure, you will lie on your left side. The lining of the stomach, esophagus and upper small intestine will be examined. If necessary, biopsies may be obtained through the endoscope.
One of our experienced nurses will observe you closely throughout the procedure to ensure you are as comfortable as possible. During the procedure, you may feel a sensation of gas, the feeling of the scope in your abdomen and possible gagging in the back of your throat.
The procedure lasts between 15 and 60 minutes. Food and liquids will be restricted until your gag reflex returns.
When your procedure is complete.
Due to the sedation effects of from the medication you received, your doctor may talk to your loved ones or speak with you at a later time. Your postprocedure discussion may involve a phone call from your doctor or a follow-up visit at your doctor's office.
We know you will be awaiting the results of your exam and we will do our best to get them back as swiftly as possible. Please note that it may take several days to a week before your doctor receives results of any biopsies taken.
We'll help find the doctor who's right for you.
