Gastroesophageal reflux in children: is there a place for the upper gastrointestinal study?
Insights
Gastroesophageal reflux in children is difficult to diagnose. Both 24-hour pH monitoring and upper GI exams are useful but measure different aspects of reflux and should complement clinical symptoms.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Diagnostic Imaging
Background:
- Objective tests for pediatric gastroesophageal reflux (GER) show limited correlation with clinical symptoms.
- Accurate diagnosis of GER is crucial for effective treatment in children.
Purpose of the Study:
- To compare the diagnostic utility of 24-hour pH probe monitoring and standardized upper gastrointestinal examinations in children with suspected GER.
- To assess the correlation between these two diagnostic modalities and clinical presentation.
Main Methods:
- Thirty-four children with suspected GER underwent both 24-hour pH monitoring and upper gastrointestinal contrast examinations.
- Data on patient age and clinical findings were collected.
- Results from both tests were analyzed for positive findings and correlations.
Main Results:
- 16 children (47%) had documented significant GER. 11 were positive on pH monitoring, 9 on contrast studies, and 4 were positive on both.
- No correlation was found between pH monitoring criteria and radiographic findings.
- The group with positive contrast studies did not differ in age or clinical findings from the general GER-positive population.
Conclusions:
- 24-hour pH monitoring and upper gastrointestinal examinations likely assess different facets of pediatric GER.
- These diagnostic methods are complementary and should be used in conjunction with clinical symptoms for comprehensive evaluation.
- Correlation with clinical symptoms remains essential for accurate GER diagnosis in children.
Abstract:
Objective tests for gastroesophageal reflux in children have shown only fair correlation with clinical symptoms. Thirty-four children referred to the pediatric surgery service for evaluation of gastroesophageal reflux had both 24-hour pH probe monitoring and standardized upper gastrointestinal examinations. A total of 16 children (47%) had documented significant or pathologic gastroesophageal reflux, 11 on pH monitors and 9 on contrast examinations. There were 4 in whom both tests were positive. None of the pH monitoring criteria correlated with the radiographic studies. The patient population documented by contrast study did not differ from the general test-positive population by age or associated clinical findings. The 2 studies probably measure different aspects of significant gastroesophageal reflux, are confirmatory and complementary, and must be correlated with the clinical symptoms.
