Capsule-Newer Method for measurement of acid exposure in the esophagus

A newer method for prolonged measurement (48 hours) of acid exposure in the esophagus utilizes a small, wireless capsule that is attached to the esophagus just above the lower esophageal sphincter. The capsule is passed to the lower esophagus by a tube inserted through either the mouth or the nose. After the capsule is attached to the esophagus, the tube is removed. The capsule measures the acid refluxing into the esophagus and transmits this information to a receiver that is worn at the waist. After the study, usually after 48 hours, the information from the receiver is downloaded into a computer and analyzed. The capsule falls off of the esophagus after 3-5 days and is passed in the stool. (The capsule is not reused.)
