What is the Bravo PH Study?

This new technology allows us to accurately measure acid reflux for 48 hrs in the esophagus and to correlate the acid level in the esophagus with the symptoms. The capsule is temporarily attached to the wall of the esophagus during an upper endoscopy (under sedation). The capsule transmits readings by radio telecommunications to a receiver worn on your belt.

You will be asked to keep a diary to record events such as eating, drinking and lying down. Also if you have any of these symptoms such as heartburn, chest pain, cough or regurgitation.

The capsule simply falls off on its own and is lost in your bowel movements, usually within 7 -10 days (you may not see it).

How do I prepare for this test?

Seven days before the test, do not take PPI such as Omeprazole (Prilosec), Lansoprazola (Prevacid), Pantoprazole (Protonix), Esomeprazole ( Nexium) or Dexlansoprazole (Dexilant). Two days before the test, also do not take pepcid, Zantac or raglan. Generally for 5 days prior to the procedure you should stop medications or vitamins containing iron, vitamin E, fish oil, garlic tablets, ginko biloba, ginseng or aspirin like products (Advil, Motrin, Aleve, Alka-seltzer,etc). Do not eat any solid food after 7:00pm, only clear liquids after dinner until midnight. You should have nothing to eat or drink after midnight.

What should I expect during the procedure?

You will be sedated during the procedure. Some patients have an awareness of “something in the esophagus”, but patients generally tolerate it very well and do not usually have pain from the capsule.
After the study is completed you bring the recorder back to the endoscopy suite. The information will be downloaded to a computer for the doctor to review.

After completion of the study

Resume your normal diet, medication and activities. No MRI exams should be performed for 30 days.
