What is oesophageal manometry?
Oesophageal manometry is a diagnostic test that is sometimes referred to as an oesophageal function or oesophageal motility study. It is used to check how well the muscles of the oesophagus are working, as well as to measure the strength of the lower oesophageal sphincter or ‘valve’ that prevents the backward flow of food from the stomach into the oesophagus.
