RESUMO
Thirty-six (36) patients with symptomatic gastroesophageal reflux were studied. Symptoms of heartburn, regurgitation and dysphagia were scored as to their severity and compared to quantitative tests of gastroesophageal reflux. Patients were studied with the acid reflux test, fiberoptic endoscopy, esophageal mucosal biopsy with a pinch forceps, esophageal manometry and radioisotopic gastroesophageal scintigraphy. Symptoms were scored according to an arbitrary grading system as mild, moderate, or severe. There were significant correlations between symptoms scores and both the degree of endoscopic esophagitis and the gastroesophageal reflux indices as measured by the radioisotopic scintiscan, but not with the degree of histologic esophagitis or lower esophageal sphincter pressure. Review of the findings suggests the following profile for patients who might require antireflux surgery: severe symptoms, presence of endoscopic esophagitis; resting lower esophageal sphincter pressure below 10 mmHg; and gastroesophageal reflux index above 10%.
