What is oesophageal manometry?

Some people experience difficulty swallowing or chronic acid reflux symptoms in various forms. In these cases, it can be helpful to check how the esophageal (food pipe’s) muscles and sphincters (valves) are working.

High Resolution Manometry (HRM) is used to assess pressure and motor function of the oesophagus and the ability to push solid and liquids from your mouth into your stomach. Oesophageal manometry is used to evaluate:

  • Gastro-oesophageal reflux disease (GORD)
  • Difficulty swallowing
  • Functional chest pain
  • Achalasia
  • Hiatal hernia

It is almost always done before anti-reflux surgery.

What is involved with this test?

The test is performed in our clinical unit MGIU, Suite 35, Cabrini Medical Centre (map).

A numbing medication for your nose and throat will be administered to prevent discomfort during the test. Then, a thin, flexible catheter (tube) will be passed into your oesophagus through your nose, and you will be asked to swallow small amounts of water. The catheter will take measurements of muscle function as you swallow liquids and solids

Most people experience very little discomfort during the test. The test usually lasts less than thirty minutes.

Preparing for the procedure

We will give you specific instructions about how to prepare for this test. You will be asked to not eat or drink anything for at least four hours before the test, unless instructed otherwise. Make sure we are aware of all medications you regularly take to make sure none of them could interfere with the test.

What can I expect after the oesophageal manometry test?

Most people only experience minimal side effects following oesophageal manometry. You may have a sore throat or stuffy nose, but both should resolve within a few hours. Minor nosebleeds may also occur.
