48 hour Bravo pH Capsule Procedure
The Bravo pH Capsule contains a radio telemetry pH sensor and is a little larger than a “gel cap.” It is introduced orally into the esophagus, via a delivery system, that accurately inserts it above the lower esophageal sphincter.
After the capsule is positioned suction is applied drawing a small amount of the esophageal mucosa into the well of the capsule. A tiny locking pin within the capsule is advanced, penetrating the mucosa, thus attaching the capsule. Then the delivery system is withdrawn. There is no sensation or pain or discomfort when the capsule is deployed. Capsule placement takes less than 60 seconds.
The capsule is left in place to begin pH recording. Esophageal pH levels are transmitted, via radio frequency telemetry, to an external pager-size receiver for up to 48 hours. Data from the recorder is uploaded to a computer for analysis by your physician and a report is generated.
Following the study, normal functions such as swallowing and passage of food will cause the disposable capsule to slough off and pass through the patient’s digestive tract to be excreted.
Restrictions for using the Bravo pH capsule include patients with pacemakers, defibrillators or neuro-stimulators. Patients who have a history of bleeding disorders, strictures, severe esophagitis, esophageal varices and esophageal or intestinal obstructions are not candidates for the Bravo system.
