BRAVO pH Studies

Bravo pH is a wireless system used to monitor acidity levels in the esophagus, helping diagnose gastroesophageal reflux disease (GERD). A small capsule is attached to the esophageal lining, transmitting pH data wirelessly to a recorder for up to 96 hours. This allows for a more comfortable and less restrictive way to assess acid reflux compared to traditional 24-hour pH monitoring with a catheter.

· Purpose:

Bravo pH testing is used to measure the amount of acid flowing from the stomach into the esophagus, a condition known as acid reflux. This helps diagnose GERD, a condition where acid reflux occurs frequently and can cause symptoms like heartburn, chest pain, and difficulty swallowing.

· How it works:

· A small, pill-like capsule is attached to the esophageal lining during an endoscopy procedure.

· The capsule measures pH levels (acidity) in the esophagus and wirelessly transmits this data to a small receiver worn by the patient.

· The receiver records the pH data for a set period, typically 48 to 96 hours.

· The capsule detaches naturally after the monitoring period and passes through the digestive system.

· Advantages over traditional pH monitoring:

· Less invasive: The Bravo system avoids the need for a catheter to be placed through the nose and down the esophagus.

· More comfortable: Patients can typically go about their daily activities with less discomfort compared to the catheter-based test.

· More accurate: The freedom to move and eat normally during the test can provide a more accurate picture of acid exposure.

· Preparation:

Patients typically need to stop taking certain medications, like proton pump inhibitors and H2 blockers, before the test.

· What to expect:

The procedure is usually quick and performed under local anesthesia. Patients may feel some minor discomfort or a strange sensation where the capsule is attached.

· After the test:

The patient will be monitored for a period, and the data will be analysed to assess acid reflux.
