Scalloped duodenal folds in childhood celiac disease.

Unlike the adult form, childhood celiac disease has not hitherto been associated with a particular endoscopic pattern. The upper gastrointestinal tracts of 46 children with various stages of celiac disease and of 27 children with conditions other than celiac disease were examined by an endoscopist unaware of the clinical details of the patients. The scalloped configuration of duodenal folds was shown to have a sensitivity of 88% and a specificity of 87% in the diagnosis of subtotal villus atrophy. Attention to this finding, described here for the first time in childhood celiac disease, may be helpful for the diagnosis of this condition.
