Esophageal Manometry

Also known as: esophageal manometry.

What is esophageal manometry?

Esophageal manometry is a test of the function of the nerves and muscles of the esophagus, as well as the lower esophageal sphincter, that connects the esophagus to the stomach. It’s used for people who have trouble swallowing, heartburn or chest pain.

What happens during the procedure?

A thin, flexible tube with sensors along its length is placed into the mouth and then into the esophagus. The patient lies quietly on his or her side while the sensors measure the strength of the esophageal muscles. The patient may be asked to drink a small amount of water in order to test the muscles. 

Is any special preparation needed?

You may need to avoid food, drink or medication for a set period of time before the procedure.

What are the risk factors?

Bleeding, infection or perforation of the esophagus are potential complications of esophageal manometry.
