Abstract
Objective Few studies have correlated pediatric endoscopic and histologic impressions of duodenal biopsies. Method: This is a retrospective study on children undergoing upper gastrointestinal endoscopy over a period of 11 years. We investigated concordance between the gross endoscopic and histopathologic characteristics of pediatric duodenal biopsies. Results: Of 1793 children enrolled in the study, duodenal pathology was observed in 72.3%. The gross endoscopic findings showed a low sensitivity of 38.9%, specificity of 99.2%, PPV of 99.2%, and NPV of 38.3%. Concordance between the gross endoscopic and histopathologic analysis was 55.6%. Conclusion: This study showed a higher rate of pediatric duodenal pathologies than gross assessment. This emphasizes the value for acquiring routine duodenal biopsies from grossly normal mucosa.
