    Abstract:
    BACKGROUND AND AIM: Several gastrointestinal diseases are localised in the small bowel and are confirmed by duodenal biopsies upon upper gastrointestinal endoscopy. However, the clinical value of routine duodenal biopsies during endoscopy has not been satisfactorily defined and was assessed in the current study. METHODS: In 1000 consecutive patients duodenal biopsies were performed during routine upper gastrointestinal endoscopy. Endoscopic diagnoses, symptoms and the prevalence of anaemia were correlated with the histological diagnoses. RESULTS: Coeliac disease and giardiasis was diagnosed in 18 and two patients, respectively (2.0 % of all cases). In 11 (55 %) patients the diagnosis was already made macroscopically during endoscopy. The sensitivity for endoscopic diagnosis of coeliac disease MARSH III was 84.6 %. There was no correlation between clinical symptoms, the prevalence of anaemia and the diagnosis of coeliac disease or giardiasis in our cohort. CONCLUSION: Endoscopic diagnosis of advanced celiac disease (MARSH III) can be made with high sensitivity and specifity. Nevertheless, duodenal biopsy is necessary for the diagnosis of early coeliac disease or giardiasis. However, the routine duodenal sampling of normal mucosa during gastrointestinal endoscopy cannot be recommended.
