Oesophageal manometry

A diagnostic procedure that can test for reflux issues and identify problems with your oesophagus function.

What is high-resolution manometry?

High-resolution manometry (HRM) is a test to measure the strength and coordination of muscle contractions in your oesophagus, and how well the valve to your stomach is working.

If you have trouble swallowing, chest pain that isn’t related to your heart, or suspected conditions like achalasia or oesophageal spasm, HRM can help determine the best course of treatment.

What happens during a manometry test?

A thin, soft tube is passed through your nose into your oesophagus after a numbing gel/spray, and you’ll take sips of water while we record muscle activity for 20-30 mins. You may feel a brief gagging sensation as the tube goes in, and it may also cause your eyes to water, but any discomfort is usually mild and passes after a few moments.

How to prepare for your test

You’ll be giving clear, comprehensive instructions on how to prepare for your test, which may include directions on when to stop eating and drinking beforehand, and when to stop taking certain medications.

After treatment

It's likely you'll have 24-hour pH monitoring immediately following your oesophageal manometry, which is a separate test for reflux.

The data from your test(s) will be interpreted by your physiologists, who will prepare a detailed report. Your specialist consultant will review and validate that before sending it to you and the GP or consultant who referred you.

What is pH-impedance monitoring?

If you’re suffering from heartburn, a cough, regurgitation or throat symptoms, your consultant can use this test to measure how often acid and non-acid reflux occur in your body, and whether they match your symptoms. If you’re not already taking acid-suppressing medication, this test can help confirm reflux. If you are on acid-suppressing medication, it can help measure your persistent symptoms.
