Symptoms and endoscopic findings in the diagnosis of gastroesophageal reflux disease.
Two hundred and twenty patients with symptoms suggestive of pathologic gastroesophageal reflux were investigated to elucidate the ability of symptoms and endoscopic findings in establishing a diagnosis of reflux disease as measured by ambulatory 24-h pH-monitoring. Daily occurrence of heartburn or acid regurgitation had positive predictive values of 59% and 66%, respectively. pH-monitoring showed pathologic reflux in 75% of patients with esophageal mucosal erosions. Endoscopic erythema of the distal esophagus predicted reflux disease in only 53%. Symptom registration during ambulatory 24-h pH-monitoring showed that about half of the symptomatic events reported by patients with pathologic reflux occurred within 5 min of a reflux episode. The corresponding figure for patients with normal pH-monitoring was less than 20%. We conclude that it is difficult to establish a diagnosis of gastroesophageal reflux disease by patient history alone, that erythema at endoscopy correlates poorly with pathologic reflux, and that reflux disease may be present even with normal endoscopy findings.
