Esophageal Testing or Manometry

Esophageal testing or manometry measures the pressures and the pattern of muscle contractions in your esophagus. Abnormalities in the contractions and strength of the muscle or in the sphincter at the lower end of the esophagus can result in pain, heartburn, and/or difficulty swallowing. Esophageal manometry is the test used to diagnose the conditions that can cause these symptoms.

How should I prepare for esophageal testing?

An empty stomach allows for the best and safest examination, so do not eat or drink anything for 6 hours before the test. Since many medications can affect esophageal pressure and the natural muscle contractions required for swallowing, be sure to discuss with your healthcare professional each medication you are taking. Your doctor may ask that you temporarily stop taking one or more of these medications before your test.

What can I expect during the test?

A healthcare professional will apply a cream to numb the inside of your nostrils. Then a thin, flexible, lubricated tube will be passed through your nose and advanced into your stomach while you swallow sips of water. Mild, brief gagging may occur while the tube is passed through the throat. When the tube is in position, you will be sitting upright or lying on your back while the tube is connected to a computer. Once the test begins it is important to breathe slowly and smoothly, remain as quiet as possible and avoid swallowing unless instructed to do so. As the tube is slowly pulled out of your esophagus, the computer measures and records the pressures in different parts of your esophagus.

During the test, you may experience some discomfort in your nose and/or throat. The test will take approximately 30 minutes to complete and the results will be sent to your doctor’s office.
