Esophageal Manometry

Select your language:

This test measures the pressure inside the lower esophageal sphincter (LES). A thin tube is inserted through your mouth or nose and into your stomach. Once it is in place, the physician will gently pull the tube back into the esophagus and ask you to swallow. As you do so, the pressure and coordination of your muscle contractions will be measured. If the pressure is low or the LES is not relaxing properly, achalasia may be present. If the pressure is low or the LES is not contracting properly, it may indicate GERD (reflux disease).
