Background: Despite differences in the information obtained by capsule endoscopy (CE) and magnetic resonance enterography (MRE), one of these modalities is usually needed when evaluating disease activity. There are no data on patients' preference that would help guide the choice between these two modalities in these instances. Aim: To compare patients' tolerance and preference to MRE versus CE. Patients and methods: Patients with known small bowel Crohn's disease (CD) in clinical remission (Crohn's disease activity index [CDAI] ,150) or with mild symptoms (CDAI ,220) were prospectively recruited. All patients underwent MRE followed by CE. Patients were asked to fill out a questionnaire addressing specific points regarding inconvenience during the preparation for the procedures, the procedures, and postprocedures. Side effects and procedure preference were addressed. Questionnaires were included for analysis only when more than 95% of the items were addressed. Results: Fifty-six patients fulfilled inclusion criteria. Pre-exam discomfort, during-exam discomfort , nausea, vomiting, bloating, and abdominal pain were all significantly more prominent in MRE as compared to CE (P,0.0001, P,0.0001, P,0.0001, P=0.009, P=0.0002, P,0.0001, respectively). MRE was perceived as a more difficult procedure (P,0.0001). Furthermore, MRE was associated with a specific adverse event - claustrophobia. Seventy-eight percent of patients (44 patients) preferred to repeat CE as compared to 22% (P,0.0001) who preferred MRE. Conclusion: CE was better tolerated by CD patients compared to MRE and was preferred by 78% of patients. The superior tolerability of CE should be considered along with the diagnostic features, and more data sought when choosing between these two modalities for CD patients for long-term follow-up.

Video capsule endoscopy has revolutionized our ability to visualize the entire small bowel mucosa. This modality is established as a valuable tool for the diagnosis of obscure gastrointestinal bleeding, Crohn's disease, small bowel tumors, and other conditions involving the small bowel mucosa. This review includes an overview of the current and potential future clinical applications of small bowel video endoscopy. [ABSTRACT FROM AUTHOR]
