OBJECTIVE. Our goal was to evaluate the diagnosis and treatment of infants with persistent regurgitation who were referred to a pediatric gastroenterology service.
METHODS. The records of 64 infants with persistent regurgitation and without any neurodevelopmental abnormalities, underlying illness, or cigarette smoke exposure were evaluated for diagnostic workup and treatment. Forty-four infants underwent extended esophageal pH monitoring.
RESULTS. Only 8 of 44 pH studies showed abnormal acid reflux. Forty-two of these 44 infants were already on antireflux medications. Other etiologies included hypertrophic pyloric stenosis (4) and renal tubular acidosis (1). Discontinuation of medication did not result in worsening of symptoms in most infants with normal pH studies.
CONCLUSIONS. The majority of infants who were prescribed antireflux drugs did not meet diagnostic criteria for gastroesophageal reflux disease.
