The 48 hour pH probe study is used to detect the presence of acid refluxing into the esophagus, or gastroesophageal reflux disease, also known as GERD. It is also used to detect laryngopharyngeal reflux disease. Currently, this is the best method available to monitor acid exposure within the esophagus and or larynx (voice box).
The test is accomplished by passing a thin flexible catheter into the esophagus while you are asleep. A small pH recording device is attached to the lining of your esophagus. The procedure is painless, and the device is small enough not to interfere with eating and drinking normally. A recording device will be attached to your belt and you are sent home for 48 hours. Patients are asked to keep a diary of their symptoms, meals and sleep time. After 48 hours, you will return to the endoscopy center to return the diary and recording device.
The 48 hour pH probe test is used to detect acid reflux (GERD), but it can also prove helpful in, diagnosing the cause of chest pain, that is not caused by a heart condition; checking for spasms of the esophagus and determining if the esophagus is working properly; determining the cause of GERD for those patients who have not been helped by medications; and helping to evaluate the workings of the esophagus before surgery for GERD.
The 48 hour pH probe study can be performed in the Poughkeepsie location.
