Bravo pH monitoring is a capsule-based test for acid reflux. This test allows physicians to evaluate reflux symptoms and determine the best course of treatment.
How the Procedure Works
The physician places the capsule into the esophagus during an upper endoscopy. When the capsule is in place, suction is applied, drawing a small amount of tissue into the capsule. The capsule is then locked into place. The placement procedure is simple to perform and well tolerated by most patients.
The capsule begins measuring the pH levels of the esophagus immediately, transmitting pH measurements wirelessly to a small receiver worn on the patient’s waistband or belt. The receiver houses three symptom buttons, the patient will press the corresponding button when they experience heartburn, regurgitation, or chest pain during the procedure. The patient will also keep a diary and record periods of sleeping and eating during the test.
Upon completion of the test, the patient will return the recording device and diary to their physician’s office. The data will be uploaded and analyzed to determine the appropriate diagnosis. The disposable capsule will spontaneously detach and pass naturally through a bowel movement a few days after the test.
