GASTROESOPHAGEAL REFLUX IN CHILDREN
1998
BACKGROUND: Gastroesophageal reflux is common in small children. It is important to recognise that its natural history and management differ from reflux in adults. OBJECTIVE: This article will summarise the clinical presentation, pathophysiology, appropriate investigations and therapy of reflux in small children. DISCUSSION: A small amount of regurgitation is common in infancy, and is only pathological if it results in harm. In children, reflux-induced injury can result from either acid exposure, nutrient loss or respiratory complications. Recognised presentations include heartburn, oesophagitis, infant irritability, dysphagia, haematemesis, stricture, growth failure, aspiration, apnoea and pneumonia. Excessive crying and irritable behaviour in infancy can be due to a variety of causes, but there is a fashionable tendency to assume that gastroesophageal reflux is a major factor. Regurgitation can be a symptom of other conditions such as infection or metabolic disturbance. It is important to carefully evaluate any infant with distressed behaviour to exclude a significant medical cause. Prolonged oesophageal pH monitoring is a very useful means of linking episodes of reflux with putative symptoms. The severity of gastroesophageal reflux tends to improve with age in infants and this should be considered when advising appropriate therapy, especially fundoplication.
