Esophageal Manometry

Your esophagus is a muscular tube connecting your throat to your stomach. With each swallow, the esophagus muscle contracts and pushes food into the stomach. At the lower end of the esophagus, a valve (a special sphincter muscle) remains closed except when food or liquid is swallowed or when you belch or vomit.

When you have problems with heartburn, pain or difficulty swallowing, an esophageal manometry test may be prescribed by your doctor.  This test measures the pressures and pattern of muscle contractions in your esophagus. Abnormalities in the contraction and strength of the sphincter in the esophagus will be evaluated and identified with this test.
