Background and Aim: Until the approval of patency capsule, capsule endoscopy (CE) has not been routinely applied for the diagnosis of Crohn's disease (CD) in Japan. We aimed to survey current situation of CE use for patients with CD in Japan. Methods: The nationwide survey of 40 Japanese institutions identified 94 patients with established CD (eCD) and 80 patients with suspected CD (sCD), who were examined by CE. Types and positive rates of mucosal injury under CE and capsule retention rate were investigated. In sCD, final diagnosis after CE was also analyzed. Results: Patients with eCD comprised 82 patients of ileitis or ileocolitis type, while 12 patients had CD of colitis type. CE identified mucosal injuries in 83 of 94 patients. Eight of 12 patients with eCD of colitis type had ileal lesions under CE, thereby being reclassified as ileocolitis type. In patients with sCD, CE detected mucosal injuries in 58 patients. Linear ulceration and cobblestone appearance were depicted in 22 and 3 patients, respectively, thereby resulting in established diagnosis of CD in 23 patients. Mucosal lesion was not found in 22 patients with sCD, who were diagnosed as not having CD. Capsule retention rate was not statistically different between patients with eCD and those with sCD (7.4% vs 6.3%, P=1.0). Conclusions: CE is useful for the evaluation of small bowel mucosal injuries in Japanese patients with sCD and eCD. Possible intestinal stricture needs to be carefully evaluated before CE even in patients with sCD.
