intragastral h2 may result from h2-reflux from the small bowel , because there was no difference in bacterial growth in gastric and duodenal juice and in gastric mucosa of patients with high and normal h2 concentrations in the stomach and because a motility disturbance of upper gi-tract ( prolonged gastric emptying time ) correlated well with h2-concentrations ( p less than 0.05 ) .
