Esophageal manometry is a test that gauges how well your esophagus works. During a esophageal manometry we measure the rhythmic muscle contractions (peristalsis) that occur in your esophagus when you swallow. Esophageal manometry also measures the coordination and force exerted by the muscles of your esophagus.
During esophageal manometry, a thin, flexible tube (catheter) that contains sensors is passed through your nose, down your esophagus and into your stomach.
When is esophageal manometry used?
We may recommend esophageal manometry if you're experiencing symptoms that could be related to an esophageal disorder. Those symptoms may include:
- Difficulty swallowing (dysphagia)
- Pain when swallowing (odynophagia)
Esophageal manometry may be used to help diagnose a number of conditions:
- Swallowing problems (dysphagia)
How to prepare for an esophageal manometry
We may ask you to avoid eating and drinking for a certain length of time before esophageal manometry. Your doctor will give you specific instructions. Also, tell your doctor about any medications you're taking. You may be asked not to take some medications before the test.
