title: Food-stimulated gastro-oesophageal reflux demonstrated by barium examination.
abstract: A prospective investigation on gastro-oesophageal reflux in 97 consecutive patients has been carried out by means of a barium examination employing the conventional method and after food stimulation. Gastro-oesophageal reflux was observed in 38 patients with and 15 patients without oesophageal symptoms. Gastro-oesophageal reflux was induced by two mechanisms, an active component after food stimulation and a passive component after the conventional method including respiratory manoeuvres and leg raising. In 32 patients, only the active component could be demonstrated and in 6 patients only the passive component. In the remaining 15 patients both active and passive components occurred. The clinical significance of the active and passive components in gastro-oesophageal reflux needs further investigation.
