For the diagnosis of reflux disease in patients that present no esophageal erosions in the endoscopy.
· For the diagnosis of reflux disease in patients that present no esophageal erosions in the endoscopy.
· To verify the gastroesophageal reflux in patients with lung or otorinolaryngological (ear, nose and throat) problems.
· To evaluate the efficacy of treatment with acid-inhibiting drugs.
· For the study of patients with chest pain not caused by heart problems.
· In anti-reflux surgery postoperative patients, in order to verify the success of the surgery.
The study consists of two steps:
* Following topical application of xylocaine spray in the throat, a manometry catheter is inserted through the nose to measure the length of the esophagus. This pH-monitoring catheter is subsequently pulled back to the desired position. This catheter has an acid-sensing device at the tip and remains in that position for 24 hours.
* The catheter protruding from the nose is connected to a device that attaches to the body by means of a belt.
Esophageal pH monitoring is a useful study for the diagnosis of gastroesophageal reflux disease. The test measures the acidity (pH) level of the esophagus during a 24-hour period.
The device that records the pH (acidity) of the esophagus has several buttons that you should press according to your activities. We will explain how to use them appropriately once we have concluded with the placement of the device.
During the 24-hour study the patient should continue his normal life and eat regular meals at the usual times, however he should take into account that:
* He can eat as soon as the placement of the catheter is completed.
* He should not bathe during the 24-hour period of the study.
* He can go to work after the positioning of the catheter.
* You should not have anything to eat or drink (fast) for at least 6 hours prior to the study.
* You should tell us what medications you take, as some should be suspended 2 days before the monitoring period and others 7 days before the monitoring period.
