Bravo Endoscopy (EGD) pH Monitoring & Procedure Instructions

This test is used to determine the presence and severity of gastroesophageal reflux disease (GERD). Common symptoms of GERD include heartburn, chest pain, coughing and sore throat. A 48-72 Hour Bravo Endoscopy (EGD) pH Monitoring Test is performed using upper endoscopy (EGD) to temporarily attach a capsule to your esophagus to monitor and measure acid reflux from your stomach. The data collected during this study can help your provider treat your symptoms.

48-72 Hour Bravo Endoscopy (EGD) pH Monitoring Instructions

Bravo endoscopy (EGD) is a system that includes a small pH-sensing, wireless capsule that is temporarily attached to the wall of the esophagus. The capsule measures pH levels in the esophagus and transmits readings and collects data on a small, external receiver worn on your belt or waistband for 48-72 hours.

Because we are interested in knowing whether certain symptoms are associated with acid in the esophagus, we will ask you to keep a written log. In this log, you will mark the time and duration of certain symptoms, such as chest pain, heartburn and cough. You will receive more detailed instructions prior to your procedure.

You’ll return the receiver and written log when the monitoring period is over. Information on the receiver will be downloaded to a computer and the results will be analyzed.

Any procedure has risks, but the Bravo endoscopy (EGD) test typically results in few complications. You may have a sore throat from the endoscopy (EGD) for a day or so. Rarely, those who have this test might feel some discomfort when swallowing. There are other possible but very unlikely risks that may include damage to the tissue of your esophagus or intestines, possible bleeding, or aspiration (breathing in) of the capsule.
