Are endoscopic changes predictive of histologic esophagitis in children?

Area of Science:

• Pediatric Gastroenterology
• Gastrointestinal Endoscopy
• Histopathology

Background:

• Clinical assessment of esophagitis in children often relies on endoscopic visualization.
• The correlation between visible esophageal mucosal changes during endoscopy and definitive histologic diagnosis of esophagitis is debated.

Purpose of the Study:

• To evaluate the predictive value of gross mucosal changes observed during upper endoscopy for diagnosing histologic esophagitis in pediatric patients.
• To determine if endoscopic findings alone are adequate for ruling out esophagitis in children.

Main Methods:

• Retrospective review of medical records for 279 pediatric patients.
• Analysis of data from patients who underwent both upper endoscopy and simultaneous esophageal biopsy.
• Comparison of endoscopic findings with histopathologic results.

Main Results:

• A significant proportion (30%) of pediatric patients with no gross mucosal abnormalities on endoscopy showed evidence of esophagitis on biopsy.
• There was a weak association between the presence of endoscopic findings and the diagnosis of histologic esophagitis.
• Endoscopic evaluation alone demonstrated poor predictive value for histologic esophagitis.

Conclusions:

• Gross esophageal mucosal changes observed during endoscopy are unreliable indicators of histologic esophagitis in children and adolescents.
• Endoscopic evaluation alone is inadequate for diagnosing suspected esophagitis in pediatric patients.
• Esophageal biopsies are essential for accurate diagnosis, even in the absence of visible mucosal abnormalities during endoscopy.
