This procedure is done on an out-patient basis in the G.I. lab by the doctor. It is a short procedure generally taking 30 minutes. A flexible fiberoptic gastroscope is passed through the mouth and down into the small intestine which enables the doctor to observe the gastrointestinal lining. The design of the gastroscope allows the doctor to take small tissue samples (biopsies), to photograph any abnormal findings, or to remove polyps, growths, or foreign bodies from the esophagus or stomach. All of these maneuvers are painless.
During this procedure your physician will place a pH capsule, approximately the size of a gelcap, in your esophagus. Throughout the test period, the Bravo pH capsule measures the pH in the esophagus and transmits this information to a small receiver worn on your belt or waistband just like a pager or mobile phone.
It will be necessary to sign a consent form for the examination. If you have any questions about the consent form or the procedure, please ask your doctor or nurse.
You will keep a diary after the monitor is placed. It is very important that you record events related to possible reflux by using the buttons on the receiver. You must also record meal times as well as anytime you lay down in a bed or recliner. This information will be reviewed with you on the day of your procedure.
