title: [Undiagnosed celiac disease in adults unmasked by endoscopy].
abstract: BACKGROUND
  Celiac disease may be present in many patterns other than the classical manifestations of diarrhea and malabsorption. The prevalence of celiac disease is greater than usually reported as mild cases are often undiagnosed. Diagnosing celiac disease may have major health significance.
  
  
  OBJECTIVE
  The aim of our study was to determine the prevalence of celiac disease in adults appearing for endoscopy with abdominal pain, in an open access setting.
  
  
  METHODS
  Two hundred and seventy consecutive, non-selected adult patients undergoing upper endoscopy for abdominal pain were included in the study. Three biopsies were routinely taken from the second part of the duodenum. In those cases with flattened villi on histology, antiendomysial antibody (AEA) was tested.
  
  
  RESULTS
  The prevalence of celiac disease among Israeli patients undergoing endoscopy for abdominal pain was high (1:23), greater than its highest reported prevalence in general populations (1:200-300).
  
  
  CONCLUSIONS
  Routine small bowel biopsies should be considered in patients undergoing upper endoscopy for otherwise unexplained pain.
