Endoscopic Duodenal Biopsies in Coeliac Disease and Duodenitis

Endoscopic duodenal biopsies were taken from 27 patients with suspected coeliac disease and compared with intubation capsule jejunal biopsies. The specimens were reported without knowledge of the patients' names or symptoms. In 24 patients (89%), coeliac disease could either be diagnosed or excluded with 100% accuracy, despite the inability to orientate the biopsies correctly. Six biopsies were considered technically unsatisfactory, but only in three (11%) was it impossible to exclude coeliac disease. Duodenal biopsies were also taken from 118 consecutive patients attending for routine upper gastrointestinal endoscopy, and 1 patient with coeliac disease was discovered. We conclude that endoscopic duodenal biopsies are a reliable and worthwhile screening test for coeliac disease in certain patients attending for routine upper gastrointestinal endoscopy.
