Procedures
Bravo PH Monitoring
Bravo PH monitoring is a minimally invasive test that measures acid levels in the esophagus over 24 to 48 hours. This procedure helps diagnose gastroesophageal reflux disease (GERD) and assess the severity of acid reflux by tracking acid exposure during normal daily activities.
Overview
Bravo PH monitoring involves attaching a small, wireless capsule to the lining of the esophagus during an upper endoscopy. The capsule records acid levels over 24 to 48 hours, transmitting data to a receiver worn by the patient. The patient resumes normal activities during the test, and the capsule naturally detaches and passes through the digestive system.
Purpose of the Procedure
Bravo PH monitoring is used to evaluate acid reflux by measuring pH levels in the esophagus over an extended period, helping to diagnose gastroesophageal reflux disease (GERD) and determine the severity and frequency of acid exposure.
How to Prepare
For Bravo PH monitoring, patients must stop taking proton pump inhibitors (PPIs) and antacids for up to seven days before the test unless otherwise instructed. Fasting is required before the procedure, and patients should wear comfortable clothing as the capsule is attached through an upper endoscopy.
What to expect after
After Bravo PH monitoring, patients can return to regular activities immediately. Mild throat discomfort may occur from the capsule placement during endoscopy, but it subsides quickly. The capsule naturally detaches and passes through the digestive tract within 5 to 7 days without the need for removal.
Complications & Risk
Bravo PH monitoring is generally safe, but some patients may experience minor throat irritation or discomfort during capsule placement. Rare complications include difficulty swallowing, capsule retention, or esophageal injury. If the capsule fails to detach naturally, an endoscopy may be required for removal.
Results and Follow-up
For Bravo PH monitoring, the data collected over the 24 to 48-hour period is analyzed to evaluate the frequency and severity of acid reflux. Results are generally reviewed within a week, and the doctor will explain whether acid exposure is contributing to symptoms. Based on the findings, medications, dietary changes, or surgical options may be recommended.
