title: Radiographic demonstration of a wireless capsule pH monitor in the esophagus.
abstract: Monitoring of esophageal pH is a major component of the evaluation of gastroesophageal reflux disease. A recent innovation has led to the replacement of the intraluminal probe by a wireless capsule. This capsule is attached to the esophageal wall and transmits the appropriate data to a patient-worn receiver. After a short period of time the capsule detaches itself from the wall and is eliminated. We recently encountered a patient in which the capsule did not detach in a timely manner. It was imaged during a preoperative esophagogram.
