Abstract
Background: In Crohn's disease (CD) a small bowel study-in addition to colonoscopy-is considered necessary for diagnosis/staging. In this study we re-examined the role of capsule endoscopy (CE), colonoscopy, imaging tests [magnetic resonance enterography/computed tomographic enterography (MRE/CTE)], and inflammatory markers [fecal lactoferrin and C-reactive protein (FL/CRP)] in CD patients who had undergone intestinal resection and in those who never had surgery. Methods: In this retrospective study 43 consecutive patients underwent CE because of staging/symptoms unexplained by colonoscopy/imaging. We compared colonoscopy, imaging, and FL/CRP with CE and evaluated the impact of the latter on clinical management and outcomes. Results: In patients who never had surgery imaging was negative with a positive CE in 8/15 (53%) of cases. Colonoscopy was insufficient for disease staging in 10/20 (50%) cases. CRP and FL were normal with a positive CE in 35% and 28% of cases, respectively. CE findings changed the management in 6/20 (30%) of cases, with 83% showing clinical/biochemical improvement after up to 15 months of follow-up. In postoperative patients CE was positive with negative imaging in 6/8 (75%) cases. Colonoscopy was insufficient for disease staging in 13/22 (59%) cases. CRP and FL were normal in 42% and 31.8% of patients with positive CE. In these patients CE findings changed the management in 12/23 (52%) cases with 83% of them showing clinical/biochemical improvement after up to 18 months of follow-up. Conclusions: Omitting CE from diagnostic/staging algorithms in CD tends to underdiagnose clinically significant small bowel lesions, thus impacting on patients' management and outcomes. 10.1093/ibd/izy048_video1izy048.video15794820403001.
