Esophophageal Manometry(Esophaphageal Motility)

This test is to determine the strength and muscle coordination of the esophagus when you swallow food. Normally when you swallow, muscles in your stomach should contract and relax, known as peristalsis. It is this action which moves food down into the stomach.

When the muscles don´t function properly you may have the following symptoms:

Heartburn or reflux

Difficulty in swallowing

Esophageal spasms

Respiratory infections Due to aspiration of stomach contents

The test is very useful because it can aid in the diagnosis of achalasia, chest pain, gastro-oesophageal reflux (GERD), and motility disorders. It may also be used to help in the diagnosis of pressure in the stomach (gastric motility), small intestine (small intestine manometry) and rectum (anorectal function)

What happens during an Esophageal manometry?

The test takes about 30-60 minutes to perform. During this time a thin catheter (tube) is placed down through the nose or the mouth and positioned in the esophagus. It is attached to a machine that records the contractions (movements) of the esophageal muscle.

In some cases the nose may be anesthetized with a solution or a spray to make it more comfortable when inserting the catheter (tube). During the test you may be asked to swallow, and the contractions (movements) will be recorded on a graph which can then be analyzed by a gastroenterologist or doctor.

Preparation for the test:

Your hospital will advise you, but usually you are requested not to eat or drink for about 12 hours prior to the procedure.

If you are taking medications you will be advised by a member of the medical profession if you should continue to do so or not.

Following the procedure
You will be checked over and your blood pressure may be taken, prior to returning home to your normal activities.
