[Radiological and manometric study of gastroesophageal reflux in normal infants]
Insights
Gastroesophageal reflux is uncommon in healthy infants. Lower esophageal sphincter pressure and length decrease with age, suggesting developmental factors influence reflux incidence in infants.
Area of Science:
- Pediatrics
- Gastroenterology
- Infant Health
Background:
- Gastroesophageal reflux (GER) is a common concern in infants, but its incidence and underlying physiological factors in healthy populations require further elucidation.
- Understanding the normal development of the gastroesophageal junction is crucial for differentiating physiological reflux from pathological conditions.
Purpose of the Study:
- To investigate the incidence of gastroesophageal reflux in healthy infants aged 2-24 months.
- To assess the relationship between age and the pressure and length of the gastroesophageal sphincter in this cohort.
Main Methods:
- A cohort of 39 healthy infants (2-24 months) underwent X-ray studies of gastroesophageal passage and esophageal manometry.
- Radiological assessment and manometric measurements were used to evaluate reflux and sphincter function.
Main Results:
- Only 3 out of 39 infants (7.7%) demonstrated radiological evidence of gastroesophageal reflux.
- Lower esophageal sphincter (LES) pressure and length were found to be inversely correlated with age, with higher pressures and lengths observed in infants younger than 6 months.
- Infants older than 6 months exhibited lower LES pressures and shorter sphincter lengths.
Conclusions:
- Gastroesophageal reflux is infrequent in healthy infants within the studied age range.
- Age-related changes in lower esophageal sphincter pressure and length appear to be significant factors in the development and potential resolution of gastroesophageal reflux in infants.
Abstract:
The incidence of the gastroesophageal reflux was studied in 39 healthy infants with ages between 2 and 24 months. X-ray studies of gastroesophageal passage and esophageal manometry were practiced in all cases. Only 3 infants showed radiological reflux. The pressure in the gastroesophageal sphincter was normal in all babies and the highest pressures were reached less--than 6 months--old infants. Older infants showed lesser pressures. The same was true for the length of the gastroesophageal sphincter. The factors involved in the genesis of the gastroesophageal reflux are discussed.
