Oesophageal manometry (also called oesophageal motility) is a procedure to measure the strength and function of your oesophagus and provides information about how the muscles in your throat and oesophagus work as food and liquids pass from the mouth to the stomach.
The most common use for oesophageal manometry is to evaluate the lower oesophageal sphincter in patients who have gastro-oesophageal reflux disease (GORD).
Manometry often can identify weakness in the lower oesophageal sphincter that allows stomach acid and contents to back up into the oesophagus.
Manometry can diagnose several oesophageal conditions that result in food sticking after it is swallowed. For example, achalasia is a condition in which the muscle of the lower oesophageal sphincter does not relax with each swallow. As a result, food is trapped within the oesophagus. Manometry reveals an absence of the waves and the contraction of the muscle everywhere in the oesophagus at the same time.
Abnormal function of the body of the oesophagus may result in food getting stuck. In patients with scleroderma the waves of muscular contractions fail to occur. With oesophageal spasm the entire oesophageal muscle may contract at one time which can cause discomfort, pain and obstruct food passage.
Oesophageal manometry is performed for the following reasons:

You should not eat for up to 6-12-hours before the test but you can drink water up until the start of the study.
You will be advised about which medications you should stop before the test.
The results from your oesophageal manometry will be reported on by the consultant clinical scientist and forwarded to your referring consultant where your next steps can be discussed and organised.
These are minor and include mild sore throat, rare nose bleed and, very uncommon sinus problems due to irritation and blockage of the ducts leading from the sinuses and into the nose.
