title: Endoscopic features of celiac disease in children.
abstract: BACKGROUND
  Endoscopic abnormalities have been described in adult patients with celiac disease that may suggest the diagnosis, especially when the presentation is atypical.
  
  
  METHODS
  The duodenum of 140 children undergoing EGD for various different indications was evaluated macroscopically and histologically.
  
  
  RESULTS
  Histology revealed total villous atrophy in 80 patients, 79 of whom had celiac disease. Among these, 100% had a mucosal mosaic pattern in the duodenum (sensitivity 98.7%, specificity 96.7%, positive predictive value 97.5%, negative predictive value 98.3%), 70% had scalloped duodenal folds (sensitivity 68.7%, specificity 98.3%, positive predictive value 98.2%, negative predictive value 70.2%), 15% had visible vasculature, and 6% had reduction of duodenal folds. Sensitivity and specificity of endoscopic findings were not modified by chromoendoscopy. Except for the mosaic pattern, the frequency of endoscopic abnormalities increased with age; reduction of duodenal folds was never seen in children with celiac disease who were less than 5 years of age.
  
  
  CONCLUSIONS
  The frequency and diagnostic value of endoscopic abnormalities are different in children with celiac disease compared with adults with this disease. Because indications for endoscopy, such as abdominal pain, dyspepsia, and unexplained anemia, can be manifestations of celiac disease, and villous atrophy may have a patchy distribution, awareness of these endoscopic abnormalities is important in the diagnosis of celiac disease in children.
