The proton pump inhibitor test and the diagnosis of gastroesophageal reflux disease.
2010
There continues to be significant controversy related to diagnostic testing for gastroesophageal reflux disease (GERD). Symptoms of GERD may be associated with physiologic esophageal acid exposure measured by intraesophageal pH monitoring or pH-impedance monitoring, and a significant percentage of patients with abnormal esophageal acid (or weak acid) exposure have no or minimal clinical symptoms of reflux. On the other hand, endoscopic lesions are only present in a minority of GERD patients. In clinical practice, presumptive diagnosis of GERD is reasonably assumed by the substantial reduction or elimination of suspected reflux symptoms during the therapeutic trial of acid reduction therapy, the so-called proton pump inhibitor (PPI) test. We aimed to assess the optimal cutoff value and duration of this test in GERD patients with and without esophagitis. We conducted a prospective study of 544 patients, endoscopically investigated and treated for 2 weeks with PPIs at double dose, and for an additional 3 mon...
