Esophageal manometry measures the strength and muscle coordination of your esophagus when swallowing. To start, a topical anesthetic may be applied to the patient’s nose to ensure comfort. A nurse then passes a thin, pressure-sensitive tube through the nose and down the esophagus into the stomach. The patient is asked to swallow water several times throughout the test and the esophageal contractions are recorded for analysis. This test is used to identify issues with movement and pressure in the esophagus that may lead to other issues such as heartburn. You may undergo this test if you have difficulty swallowing, heartburn or reflux, non-cardiac chest pain, as well as prior to anti-reflux surgery.
