title: Patterns of postcibal gastroesophageal reflux in symptomatic infants.
abstract: Symptomatic infants displayed three patterns of gastroesophageal reflux after drinking apple juice (20 ml/kg or 300 ml/m2 of body surface area). The type I pattern occurred in patients who had continuous postcibal gastroesophageal reflux, large hiatal hernias and frequently required an antireflux operation. A functional motility disorder suggesting delayed gastric emptying appeared to be important in infants with discontinuous reflux (type II pattern). These infants had frequent gastroesophageal reflux for only 2 3/4 hours postcibally, antral-pylorospasm, increased low esophageal sphincter pressures, and a high incidence of pulmonary symptoms and non-specific watery diarrhea. The mixed (type III) pattern of gastroesophageal reflux occurred in a small number of infants and exhibited features of both type I and II patterns.
