Gastrooesophageal reflux during liquid and solid meals. A reevaluation of the de Carvalho test

Gastrooesophageal reflux during liquid and solid meals was investigated in 43 patients with upper abdominal dyspepsia. Gastrooesophageal reflux occurred in 45% of the patients after a solid meal and in 90% after a liquid meal. Differences in oesophageal motility during liquid and solid meals are discussed as a possible explanation of the phenomenon.
