Endoscopic markers for celiac disease

Abstract

Celiac disease is common and can present with nonspecific upper gastrointestinal symptoms. Patients may therefore undergo esophagogastroduodenoscopy as their initial investigation. Markers of villous atrophy, which can be seen in the duodenum during endoscopy, are well described. They have limited sensitivity for patients with mild enteropathy and duodenal biopsies should be performed if there is strong suspicion of celiac disease irrespective of endoscopic appearance. Endoscopic markers do, however, allow the selection of patients with nonspecific symptoms for duodenal biopsy, and these markers should, therefore, be looked for routinely during esophagogastroduodenoscopy.

Key Points

  • Celiac disease is common and can present with upper gastrointestinal symptoms rather than malabsorption

  • Esophagogastroduodenoscopy might be the first investigation ordered in patients with celiac disease

  • There are well-defined markers of villous atrophy in the duodenum that should be routinely looked for during endoscopy

  • The absence of endoscopic markers should not preclude biopsy if celiac disease is strongly suspected, because the markers lack sensitivity, particularly for mild enteropathy

  • Endoscopic markers are useful in the selection of patients who have nonspecific upper gastrointestinal symptoms for biopsy
