Bravo pH monitoring via wireless capsule

Accurate diagnosis leads to proper treatment. This is especially true when it comes to diagnosing GERD, or gastroesophageal reflux disease. At Utah Gastroenterology, our doctors use the advanced Bravo pH monitoring test to evaluate gastroesophageal reflux disease and to determine the effectiveness of medications prescribed to prevent acid reflux. This test measures the amount of acid reflux, or backing up, of contents from the stomach into the esophagus (food pipe).


What is the Bravo pH monitoring procedure? 

Bravo pH monitoring uses a small capsule that is attached to the esophageal lining. The capsule is approximately the size of a pencil eraser. It contains an acid-sensing probe, a battery and a transmitter. During upper endoscopy under anesthesia, we introduce the capsule into the esophagus using a special catheter placed into the mouth. We attach the capsule to the lining of the esophagus. We then detach the catheter from the capsule. The capsule probe monitors the acid in the esophagus and transmits the information to a small recorder the patient wears on a belt.

This method offers many advantages, including:

  • Not leaving the catheter protruding from the patient's nose for the recording.
  • The monitoring period is 48 hours (two days) and allows us to capture more symptom events.
  • During the recording period, you can go about your usual daily activities – eating, sleeping and working.
  • Patients keep a record of their meals, periods of sleep and symptoms both in a diary and by pushing buttons on the recorder.
  • The diary helps us interpret the results.
  • The patient returns after 48 hours (or sends the recorder back after 48 hours) so we can download and analyze the data from the recorder.
  • The capsule eventually falls away from the esophageal lining, usually after five or more days, and is passed in the stool during a bowel movement.

BRAVO pH has the potential to provide a more accurate picture of acid exposure, especially when compared to data collected using older catheter-based systems where normal activities may be limited. 


Barrx® Halo for treatment of Barrett’s esophagus 

At Utah Gastroenterology, our doctors are using Barrx Halo radiofrequency ablation for the removal or destruction of abnormal tissue created by Barrett’s esophagus. This is a nonsurgical treatment option that helps reduce the patient’s risk of developing esophageal cancer by treating the diseased tissue that causes Barrett’s esophagus. Barrett's esophagus is typically caused by chronic untreated GERD. The continuous reflux of stomach acid and bile eats away the lining of the esophagus, which can lead to Barrett's esophagus and esophageal cancer. 


What is the Barrx® Halo procedure? 

Radiofrequency ablation with Barrx Halo uses a special electrode mounted on either a balloon or an endoscope to deliver heat energy precisely to the diseased lining of the esophagus. The procedure takes about 30 minutes and is well-tolerated and painless for patients. In many cases, more than one treatment is required for maximum effectiveness.
