Esophageal Manometry
Esophageal manometry is a test used to measure the function of both upper and lower esophageal sphincter (the valve that prevents reflux of gastric acid into the esophagus) and the muscles of the esophagus. This test will tell your doctor whether your esophagus has any abnormal contraction. To know why you might be experiencing a problem with your digestive system, it helps to understand the swallowing and digestive processes.
The esophagus is a muscular tube that connects your throat to your stomach. With each swallow the esophagus muscle contracts and pushes the food into the stomach. At the lower end of the esophagus, a valve (a high pressure zone area) remains closed except when food or liquid is swallowed or when you belch or vomit.
