Esophageal Motility can be measured by a test called Esophageal Manometry. Your doctor will tell you if you are a candidate for this test. It measures how well the muscles in your esophagus work. The esophagus is the tube that connects your mouth to your stomach. When you swallow, the muscles of your esophagus contract and push liquids and food down towards your stomach. This test, which will take about 1 hour, is done if you are having difficulty or painful swallowing and your doctor already ruled out any blockage. The risks, benefits, and possible complications will be discussed with you by your doctor prior to your procedure.
Your doctor will tell you not to have anything to eat or drink for 8 hours before the test. A thin flexible tube containing sensors is passed through your mouth or nose, down your esophagus and into your stomach. When the tube is in your esophagus, you will be asked to swallow. The coordinating force and pressure of the muscle contractions will be measured in the tube, along with how well the circular bans of muscles (sphincters) at the top and the bottom of your esophagus work together.
When the information gathering is complete, the tube will be removed. The results will be discussed with you by your doctor.
