[Radiologic study of gastric transit after ingestion of natural soda water]

Is a barium meal modified when soda water is used as a drink? In a series of 60 patients, the authors studied radiologically, a barium meal after taking ordinary tap water and after taking soda water. They observed after taking soda water, an increase in volume of the air pocket at the upper end of the stomach with, in 69% of cases, return to normal within 10 minutes. Gastric emptying occurred more rapidly with soda water in 40% of cases, and identically in 30% of cases.
