Esophageal Manometry Study 'EMS'



What is Esophageal Manometry?

This is a test used to examine the 'motility' or muscle contractions in your esophagus (swallowing tube). This study is done for patients with chest pain (that is not coming from your heart), dysphagia (trouble swallowing) or acid reflux (heartburn, regurgitation, cough, sore throat, asthma, etc.). The test involves inserting a soft flexible tube trough your nose and into your esophagus. The tube will not bother you as much when inserted through your nose instead of your mouth. You then swallow water while the tube is advanced into your stomach. The tube is then slowly withdrawn while pressure measurements are obtained at regular intervals.

Other than some minor irritation to your nose, there are no risks associated with this test. You are not sedated because the test is generally well tolerated and sedation would affect the muscle contractions in the esophagus. The test will take approximately 20-30 minutes and you will be able to eat and drink immediately after the test is completed.
