Delayed gastric emptying in gastroesophageal reflux disease: reassessment with new methods and symptomatic correlations.

Background: Previous studies have shown that patients with gastroesophageal reflux disease (GERD) have slower rates of gastric emptying than control subjects, but the prevalence has differed because of variations in methodology. The recent establishment of international control values for scintigraphic gastric emptying assessment makes standardization of this technique possible. It would also be useful to determine whether specific gastrointestinal symptoms predicted delayed gastric emptying in GERD.
