Esophageal Manometry

What is Esophageal Manometry?

Esophageal manometry is a test used to measure the function of the esophagus, namely its peristalsis (sequential muscular contractions that propel food and water down the esophagus) and lower esophageal sphincter (the valve that prevents reflux of gastric acid into the esophagus).

Why is Esophageal Manometry Done?

The manometry test is commonly administered to patients who have one or more of the following symptoms:

• Difficulty swallowing
• Pain when swallowing
• Chest pain
• Heartburn

This test will inform patients and their physicians if a patient’s esophagus is able to move food to his/her stomach normally. It will also diagnose disorders of esophageal function, such as achalasia and diffuse esophageal spasm.

What are the Risks Associated With an Esophageal Manometry?

Esophageal manometry is a very safe and low-risk procedure. Patients may experience some gagging, discomfort in the nose and throat during the procedure. After its completion, patients may have a stuffy nose or sore throat for a short time. Nosebleeds are rare.
