Abstract

Simultaneous 22-h measurements of intraoesophageal and intragastric pH were made in 22 patients with symptoms of gastro-oesophageal reflux (7 with peptic oesophagitis, 8 with peptic oesophageal stricture, and 7 with peptic oesophagitis and previous partial gastrectomy) to determine whether alkaline intraoesophageal pH is a consequence of alkaline gastro-oesophageal reflux. In the three groups of patients intraoesophageal pH was >7 for 16.9 ± 4.8% 27.5 ± 7.6% and 21.0 ± 7.7% respectively, of total recording time (p = NS). Intragastric pH > 7 was recorded only in the patients with partial gastrectomy (10.3 ± 5.3% of recording time; p <0.01 in comparison with the other groups). Elevations of intraoesophageal pH to >7 never occurred during episodes of alkatinization of intragastric pH. These results suggest that refluxed fluids are unlikely to be the cause of alkaline intraoesophageal pH in patients with peptic oesophagitis.
