Postcibal gastroesophageal reflux in children

Area of Science:

• Pediatric Gastroenterology
• Digestive Health
• Infant Nutrition

Background:

• The impact of feeding on childhood gastroesophageal reflux (GER) requires further clarification.
• Understanding GER patterns post-feeding is crucial for accurate diagnosis and management in children.

Purpose of the Study:

• To investigate the effects of different feedings (apple juice vs. milk-formula) on postprandial gastroesophageal reflux (GER) in children.
• To assess the influence of feeding type and body position on GER frequency and duration in both asymptomatic and symptomatic children.

Main Methods:

• Continuous distal esophageal pH monitoring was performed on 56 children (28 asymptomatic, 28 symptomatic) for 3 hours post-feeding.
• Children were fed either apple juice or milk-formula, and GER events were quantified.
• The effect of the upright position and medical/surgical interventions on GER was also evaluated.

Main Results:

• Frequent GER occurred for up to 2 hours after apple juice feedings in asymptomatic children, and longer in symptomatic children.
• Milk-formula feedings led to decreased esophageal acidity compared to apple juice for the initial 2 hours.
• Neither feeding type nor the upright position significantly reduced GER in asymptomatic children beyond 2 hours post-feeding.
• Nissen fundoplication effectively eliminated GER, correlating with an inability to burp or vomit post-surgery.

Conclusions:

• Frequent GER for up to 2 hours after clear liquid meals is likely a physiological response in children.
• Effective control of vomiting via medical or surgical therapy correlated with reduced GER beyond 2 hours post-meal.
• Surgical intervention, like Nissen fundoplication, can significantly reduce or eliminate GER episodes.
