Coeliac disease diagnosed by means of duodenoscopy and endoscopic duodenal biopsy.

Nineteen patients with suspected coeliac disease were examined by duodenoscopy and biopsy. In all patients a histopathology consistent with coeliac disease was demonstrated in endoscopic biopsies of the duodenal mucosa. On close-up view villous atrophy was seen in vivo. Fourteen patients were re-examined on a gluten-free diet. In 13 patients a restitution of the duodenal mucosa was shown. Duodenoscopy combined with biopsy seems to be a reliable method for the assessment of the mucosal change in coeliac disease.
