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.
Esophageal manometry provides information about the movement of food through the esophagus into the stomach. The test measures how well the muscles at the top and bottom of your esophagus (sphincter muscles) open and close, as well as the pressure, speed and pattern of the wave of esophageal muscle contractions that moves food along. Esophageal manometry can help diagnose the following conditions: -Diffuse esophageal spasm -Achlasia - -Scleroderma
Esophageal manometry is an outpatient procedure that is performed without sedation. It usually lasts approximately 30 minuets. The following procedure is what you would typically expect: You will be asked to sit up. The doctor will then spray your throat with a numbing medication or applies numbing gel in your nose or both. A catheter is then guided through your nose into your esophagus. The catheter may be covered by a water-filled sleeve to help it advance into your esophagus. After the catheter is in place, you will be asked to lie on your back on an exam table or to remain seated. You then be asked to swallow several small sips of water. A computer connected to the catheter records the pressure, speed and pattern of your esophageal muscle contractions as water passes through your esophagus. During the test, you'll be asked to breathe slowly and smoothly, remain as still as possible, and swallow only when you're asked to do so. The doctor might move the catheter up or down into your stomach while the catheter continues its measurements. After recording is completed, the catheter then is slowly withdrawn.
You might need to avoid eating and drinking for a time before esophageal manometry. Your doctor will give you specific instructions. Also, tell your doctor about medications you take. You might be asked not to take some medications before the test.
When your esophageal manometry is complete, you will be allowed return to your normal activities. Your doctor will discuss your esophageal manometry results with you within a few days. The test results can be part of a preoperative evaluation or help identify the cause of esophageal symptoms. Plan to discuss the results with your doctor at a follow-up appointment.
Esophageal manometry is generally safe and complications are rare. Some side effects include: -Gagging and choking -Watery eyes -Sore throat -Stuffy nose -Minor nosebleed Other complications may include esophageal perforation, and aspiration.
When should I go for an esophageal manometry?
The manometry test is commonly given to people who have: Difficulty swallowing Pain when swallowing Heartburn and/or regurgitation (bringing food back up after swallowing it)
Chest pain Is the procedure painful?
Esophageal manometry is generally safe, and complications are rare. You might, however, have some discomfort in nose and throat as well as gagging when the tube passes into your throat.
