BACKGROUND: Double-balloon enteroscopy (DBE) is theoretically useful in Crohn's disease (CD) since it is potentially able to investigate the whole small intestine, but sparse data are available. AIM: To assess the feasibility, safety, and diagnostic yield of DBE in CD. METHODS: The study was conducted in a tertiary care centre for inflammatory bowel disease. Thirty-seven patients with CD (18/19 male/female, mean age 42 years, range 13-77 years) were considered. Thirty-two DBEs from the oral approach and 18 from the anal (in 6 patients from both ways with a complete exploration in 4, 10.8%) were performed. Indications were: first diagnosis/staging in 16 cases, diagnosis of stenosis in 7, obscure bleeding in 10, suspected neoplasia in 2, and postsurgical evaluation in 2. One hundred and thirty-three other procedures (3.7 per patient) were performed with the same indication. RESULTS: Insertion depth from the oral route was 266.5 +/- 100 cm and from the anal route 72.5 +/- 60 cm. Ileocecal valve was passed in 8/13 patients, but in 4 DBE explored less than 50 cm of ileum. Diagnostic yield was 59.4% but changed according to indication (40% in obscure bleeding, 100% in case of strictures) and was higher when DBE was conducted on the basis of previous investigations (77.8% versus 40%, p = 0.037). CONCLUSION: DBE is a feasible, useful, but technically demanding method in CD. Definition of the proper introduction route by means of previous investigations is associated with a higher efficacy of DBE.
