Abstract
BACKGROUND AND STUDY AIMS
The recognition of suggestive endoscopic markers in the duodenum during open access endoscopy can help identifying patients who are likely to develop coeliac disease (CD). This study aims to determine the diagnostic accuracy of duodenal endoscopic markers for the diagnosis of CD.
PATIENTS AND METHODS
All children (0-15 years) who underwent oesophagogastroduodenoscopy (EGD) for any reason suggestive of CD at the paediatric department of Al-Assad University Hospital in Latakia, Syria during a 4-year period (from January 2010 to December 2013) were retrospectively included, in the study; this yielded a consecutive cohort without selection bias. The relevant data were obtained from the patients' files. Four duodenal endoscopic markers, including scalloping, reduction of duodenal folds, nodular mucosal pattern, and scattered white spots, were evaluated.
RESULTS
During the study period, 504 children underwent EGD of whom 123 (24.4%) were ultimately diagnosed with CD. At least one marker was observed in 200/504 children (39.6%) and the diagnostic values were as follows: Sensitivity (91%), specificity (76%), positive predictive value (56%), and negative predictive value (97%). Scalloping had the highest sensitivity and specificity of 89% and 96%, respectively.
CONCLUSION
Careful examination of the second and third parts of the duodenum during endoscopy can be helpful in identifying CD. Scalloping is the most common endoscopic marker, and the high NPV values of endoscopic markers should be interpreted cautiously, as the diagnosis of CD can be missed.
