Indications for Esophageal Manometry and pH Testing
When people eat the stomach produces hydrochloric acid to aid in the digestion of food. The stomach has a lining to help protect it during the digestion process. The esophagus or “food pipe” does not have a lining to protect it, but depends on the valve (Lower Esophageal Sphincter or LES) to contract the esophagus during the digestion period. When the LES is weak stomach acid is then allowed into the esophagus causing irritation to the lining. Over a period of time severe inflammation may occur causing the following symptoms:
- Heartburn
- Chest Discomfort
- Difficulty swallowing
Benefits and Side Effects
There are no other imaging or diagnostic tests that provide information of how the esophagus muscle works or the degree and duration of acid reflux. Thus, making esophagel manometry and pH testing the standard for diagnosing esophageal function disorders.
Generally, there are no serious side effect with Esophageal Manometry and pH testing. Testing is well tolerated once the tube is in place. Occasionally, patients may have a mild sore throat which resolves when the tube is removed.
