Endoscopy and biopsy in gastroesophageal reflux in infants and children
Insights
Gastroesophageal reflux in children has diverse symptoms beyond vomiting. Endoscopic evaluation offers valuable insights, especially for esophagitis, improving diagnosis beyond traditional barium swallows.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Endoscopy
Background:
- Abnormal gastroesophageal reflux (GER) in infants and children presents with varied symptoms, including dysphagia, pain, bleeding, failure to thrive, esophageal stricture, and respiratory issues.
- Traditional diagnostic methods like barium swallows have known limitations in accurately assessing GER complications.
Purpose of the Study:
- To evaluate the diagnostic utility of endoscopic assessment and esophageal biopsy in pediatric patients with suspected gastroesophageal reflux.
- To correlate endoscopic findings with clinical presentations and contrast esophagogram results.
Main Methods:
- Endoscopic examination and biopsy of the esophagus in 100 infants and children.
- Comparison of endoscopic findings with clinical symptoms and barium swallow results.
Main Results:
- Endoscopic examination provided significant diagnostic information, particularly for identifying esophagitis with ulceration, bleeding, or stricture.
- Esophageal biopsies were useful in confirming esophagitis but lacked absolute diagnostic power alone.
- Endoscopy revealed valuable data not always apparent in contrast esophagograms.
Conclusions:
- Endoscopic assessment is a valuable tool for diagnosing complications of gastroesophageal reflux in children.
- While biopsies confirm esophagitis, endoscopic visualization is crucial for comprehensive diagnosis.
- Endoscopy enhances diagnostic accuracy beyond traditional imaging in pediatric GER cases.
Abstract:
The clinical features of abnormal gastroesophageal reflux in infants and children extend beyond repeated vomiting and include dysphagia, pain, bleeding, failure to thrive, esophageal stricture, and recurrent respiratory symptoms including aspiration pneumonitis and cyanotic attacks. The unreliability of the traditional barium swallow examination as a diagnostic test is well known. This study reports the results of endoscopic assessment and esophageal biopsy in 100 infants and children and relates them to the clinical findings and the changes in the contrast esophagogram. The results show that further valuable diagnostic information can be gained from endoscopic examination of the esophageal mucosa, especially when there is esophagitis with ulceration, bleeding, or stricture. Endoscopic biopsies are useful to confirm the presence of esophagitis but biopsies alone do not give absolute diagnostic information.
