title: [Efficacy and reliability of pH monitoring].
abstract: We evaluable the efficacy and reliability of 24-hour pH monitoring studing the gastro-esophageal reflux. 119 patients with gastro-esophageal reflux disease (MRGE) and 60 normal subjects were tested with this method ambulatorially. The study time started at January 1991 and finished at May 1994. Symptoms of MRGE showed high specificity but a low diagnostic sensitivity; moreover they are not able to foresee oesophageal damage. On the contrary the pH monitoring showed a 95% sensitivity. DeMeester's parameters identify refluxer subjects effectively, linking it to oesophageal damage severity. Symptoms and mucoesophageal damages are distributed equally on every kind of reflux patients including upright refluxers.
