Abstract
Objective To investigate the value of double-balloon endoscopy for the diagnosis of small bowel Crohn disease（CD）. Methods Data of 141 patients with suspected CD undergoing double-bal- loon endoscopy were reviewed. Diagnosis was made based on pathological, endoscopic findings and clinic follow-up results. Detection rates and diagnosis rates of small bowel CD were compared by double-balloon en- teroscopy, CT enterography and capsule endoscopy. Results The detection and diagnosis rates of small bow- el CD by double-balloon endoscopy were 90. 8% （ 128/141 ） and 98.4% （ 126/128）, respectively. These two variables by CT enterography were 76. 0% （ 19/25 ） and 89.5% （ 17/19）, and those by capsule endos- copy were 60. 0% （15/25） and 93.3% （14/15）. Conclusion Double balloon enteroscopy has high appli- cation value for the diagnosis of small bowel CD. For those contraindicated with endoscopy, CT enterography can be considered as a preferred auxiliary diagnostic modality.
