Oesophageal manometry

You will have a local anaesthetic to numb your nose and throat. You'll most likely be sitting upright, in a comfortable position. A thin flexible tube will then be passed through your nose down your throat into your oesophagus and stomach. Once it's in place, it shouldn't be uncomfortable and you'll be able to breathe and speak normally. The tube has a series of pressure sensors, and will record the pressure as you take sips of water. It will also measure muscle contractions in the oesophagus both at rest and when swallowing. The tube will be removed after approximately ten minutes. The entire procedure will last around 45 minutes.

Your consultant will explain how to prepare for the test, and advise how long you should avoid eating and drinking beforehand. You should inform your consultant of any medication you're currently taking, and they'll let you know if you need to stop taking it for a certain amount of time leading up to the test.

It's likely you'll have 24-hour pH monitoring immediately following your oesophageal manometry, which is a separate test for reflux. Either way, you'll be able to go home the same day.

Depending on the results of your oesophageal manometry, your consultant will advise on the next steps and any potential treatment. It's likely they'll wait for the results of the 24-hour pH monitoring test to advise on any further treatment or medication.

You may experience a nosebleed or a sore throat after the test, both of which are minor and should soon disappear.
