Esophageal manometry (motility testing)

Esophageal manometry measures the pressure and coordination of the muscles in your esophagus as you swallow. It shows whether food and liquid are being pushed down properly and whether the valve at the bottom opens and closes as it should.

Who it helps

  • Trouble swallowing when an upper endoscopy looks normal
  • Suspected achalasia or other esophageal motility disorders
  • Non-cardiac chest pain
  • Before anti-reflux surgery, to make sure the esophagus can handle it

How testing works with Dr. Frank

If you need manometry, Dr. Frank refers you to a specialized esophageal motility lab for the study, then reviews the results with you and builds your treatment plan.

How to prepare

Nothing to eat or drink for about 6 hours before. Some medicines that affect esophageal muscles may need to be held; your instructions will say which.

What to expect at the motility lab

The test is done awake, without sedation, because you need to swallow on command. After a numbing gel in the nose, a thin catheter is passed through the nose into the esophagus. You then take a series of small sips of water while sensors record. The recording usually takes 10 to 20 minutes, and you can drive and eat normally afterward.

Risks

Most people tolerate it well. Brief gagging, watery eyes, a mild sore throat or a small nosebleed can occur.

Common questions

Is it painful?

It's uncomfortable during placement for most people but not painful once in place.

What happens next?

Results guide treatment, which may include medication, dilation or a procedure for achalasia.
