Esophageal manometry is an outpatient test used to identify problems with movement and pressure in the esophagus that may lead to problems like heartburn. Your esophagus moves food from your throat down to your stomach with a wave-like motion called peristalsis. Manometry will indicate how well the esophagus can perform peristalsis. Manometry also allows the doctor to examine the muscular valve connecting the esophagus with the stomach, called the lower esophageal sphincter or LES. This valve relaxes to allow food and liquid to enter the stomach. It closes to prevent food and liquid from moving out of the stomach and back up the esophagus.
Abnormalities with peristalsis and LES function may cause symptoms such as swallowing difficulty, heartburn or chest pain. Information obtained from manometry may help your doctor to identify the problem.
Your health care provider will give you written instructions on how to prepare for this test. Please follow these instructions completely and call our office if you have any questions.
