Ambulatory pH Monitoring in the Management of Reflux

Abstract

Ambulatory pH monitoring is a useful tool in the diagnosis and treatment of different esophageal and pharyngeal complaints. We have studied its use in an office setting in 15 patients with suspected gastroesophageal reflux disease (GERD). The patients were monitored for at least 18 hours while wearing a two-channel probe at home. Data obtained confirmed severe GERD in 6 patients and chest pain without GERD in 2 patients. Two patients continued to have symptoms in spite of appropriate therapy, while 2 untreated patients had symptoms of GERD with normal pH studies. We feel this technique is relatively safe and cost-effective and causes minimal disruption of the patient's life-style, while enabling the physician to monitor therapy and help achieve a good therapeutic outcome.
