Abstract: BACKGROUND: In children with inflammatory bowel disease (IBD), treatment depends on the type and extent of disease. Therefore, maximal effort should be made to provide a correct diagnosis. The aim of this study was to assess the value of a histologic diagnosis made on the basis of either ileal and colonic or rectosigmoid biopsies. METHODS: In 42 children with a known diagnosis of IBD, biopsies from rectum and sigmoid were reassessed by an expert, blinded pathologist. This histologic diagnosis was compared with the diagnosis based on (ileo)colonic biopsies and the final diagnosis. RESULTS: In patients with IBD, diagnostic accuracy of rectosigmoid histology was 0.4524. For (ileo)colonic biopsies, diagnostic accuracy was 0.7619. CONCLUSIONS: Histology on biopsies from rectum and sigmoid is insufficient for a correct diagnosis of Crohn's disease or ulcerative colitis in children. At initial presentation, an ileocolonoscopy with biopsies should therefore be performed in all children.
