Video capsule endoscopy in celiac disease: current clinical practice

OBJECTIVE: A complete examination of the small intestine is possible by video capsule endoscopy (VCE). The aim of this study was to evaluate current indications for performing VCE in celiac disease. METHODS: In all 84 celiac disease patients on a gluten-free diet who had undergone VCE were enrolled at five centers in Europe. The indications, findings and clinical impact of VCE were recorded by a structured questionnaire. VCE was also carried out in 34 consecutive patients with untreated celiac disease (controls) in another center. RESULTS: Out of the 84 patients, 34 had overt symptoms and small intestinal histology compatible with refractory celiac disease. VCE was normal in 9 patients, and 7 had only proximal and one distal atrophy, 14 had intestinal ulcer and 2 an intestinal stricture. VCE was used in the adjustment of immunosuppressive treatment in 9 patients. In the remaining 50 patients, a VCE was performed because of less severe symptoms, 31 of which had an earlier histological recovery. The VCE showed proximal small bowel atrophy in 21 and distal atrophy in 3 patients, and 3 ulcers were seen. In this group the patients received mainly advice with a view to achieving better dietary compliance. Of the 34 newly detected celiac patients, 4 were normal, 27 proximal and 3 had distal small intestinal atrophy in the VCE. CONCLUSIONS: VCE has a definite impact on the management of refractory sprue. In the remaining patients with established celiac disease, the procedure plays a more limited role.
