Patient Information (Benefits and Risks)
Benefits
Bravo pH monitoring system provides a more tolerable and convenient way to
evaluate your reflux symptoms when compared to catheter-based pH monitoring
systems.
The capsule is temporarily attached to the wall of your esophagus. The capsule
transmits pH information wirelessly to a small recorder that you wear. Data can be
transmitted approximately 2 meters (6 feet), which means that you can take the
recorder off to shower and sleep without interrupting the test.
You can engage in your usual activities during the test, which can provide your
doctor with a more accurate picture of your acid exposure compared to data collected
using catheter-based systems.
Risks
The Bravo pH test is not for everyone. If you have bleeding diathesis, strictures,
severe esophagitis, varices, obstructions, a pacemaker, or an implantable cardiac
defibrillator, you should not undergo a Bravo pH test. Additionally, because the
capsule contains a small magnet, you should not have an MRI study within 30 days
of undergoing the Bravo pH test.
Potential complications include, but are not limited to, the following events:
• perforation
• premature detachment of the pH capsule
• failure of the pH capsule to detach from the esophagus within several days after
placement or discomfort associated with the pH capsule, requiring endoscopic
removal
• tears in the mucosal and submucosal layers of the esophagus, causing bleeding
and requiring possible medical intervention
Potential complications associated with gastrointestinal endoscopy include:
• perforation or hemorrhage
• aspiration
• fever or infection
• hypertension
• respiratory arrest
• cardiac arrhythmia or arrest
Note
All pH testing procedures carry some risks. This information should not
be used as a substitute for talking with your doctor about diagnosis and
treatment.
