[Role of 24 hour intraesophageal pH monitoring in diagnosis of gastroesophageal reflux and assessment of drug effectiveness].

58 patients with gastroesophageal reflux (GER) and 18 patients with chronic gastroduodenitis (CGD) were examined using 24-h monitoring of intraesophageal pH. GER patients exhibited changes in all the readings of 24-h pH-gram of the esophagus which strongly correlated with severity of clinical symptoms (heartburn, metasternal pain), reflux-esophagitis (endoscopical picture), data of esophagotonocimography. 24-h monitoring of intraesophageal pH provided an adequate estimation of the drugs used to treat GER. As to effect on intraesophageal pH, domperidon had no effect, famotidine had a moderate positive effect, omeprasol returned pH to normal.
