Endoscopic markers in coeliac disease, Digest Liver Dis 34: 177-82. Se (sensitivities), Sp (specificity), PPV (positive predictive value), NPV (neg. predictive value), etc. of each single endoscopic sign and of all abnormalities in duodenum in group of 78 CD patients. Se (%) Sp (%) PPV (%) NPV (%) Micronodular pattern 57.7 100 89.7 89.7 Mosaic pattern 25.6 100 100 84 Reduction or loss of duodenal folds 74.3 99.3 96.7 93.5 Scalloping of duodenal folds 66.7 100 100 94.1 one or more endoscopic signs 93.6 99.3 97.3 98.3 Table I cites symptoms, duodenal appearance, and duodenal histology, with final diagnosis of patients suspected of CD. Two of 7 patients with duodenal ulcer or erosions without CD both had a decrease of duodenal folds on appearance. The other five CD patients had normal duodenal appearances but with villous atrophy upon histological evaluation. Table III cites percentages for the same endoscopic signs listed in Table II for 13 CD patients with partial villous atrophy and 65 CD patients with subtotal villous atrophy. The aim of the study was to evaluate endoscopic markers in the duodenal bulb and 2nd part of the duodenum. For more info, pls. consult citation above.
