Esophageal EndoFlip procedure

What is it?

The Esophageal EndoFlip procedure is a balloon catheter that is advanced orally down the esophagus to measure the actual diameter and distensibility of the esophagus.

Why is it done?

This procedure is done to give a more complete picture of why a patient may be having difficulty swallowing.

How do I prepare for the procedure?

  • Nothing to eat or drink for 4 hours before the procedure.  You MUST have an empty stomach.
  • No Caffeine products for 24 hours prior to the procedure (eg: coffee, tea, chocolate, or many soft drinks).
  • You may take your medications as usual.

What can I expect during the procedure?

  • A numbing medication will be sprayed into your throat to ease the passage of the balloon catheter.
  • Once the balloon is in position, a small amount of fluid will be instilled into the balloon through the catheter.  This may give a sensation of coolness at the top of your stomach and in your lower esophagus. 
  • While the balloon is inflated, the nurse will ask you to hold your breath and to not swallow while measurements are being taken.  This will only take a few seconds.  You will have a suction that you control to manage the saliva.
  • Once the measurements are taken, the balloon will be deflated and removed.

What can I expect after the procedure?

  • You may eat and drink as normal after the numb feeling is completely gone from your throat (approximately 30-60 minutes)
  • Your doctor will speak with you about the findings at your follow-up visit.
