The results of ambulatory 24 hour oesophageal pH monitoring in 20 patients with established gastro-oesophageal reflux disease were compared with those of 20 healthy individuals with normal endoscopy. Cut off limits of pH 3, 4, and 5 were superior to pH 2 with respect to the discrimination of patients from normal subjects, and for the detection of pathological reflux. Using pH 4 as a cut off limit, the ambulant and recumbent periods of pH monitoring were more discriminatory than the postprandial… CONTINUE READING
