N2 - Purpose: To prospectively compare four diagnostic small-bowel imaging techniques for depiction of abnormal findings in the same patients known to have or suspected of having Chrohn disease. Materials and Methods: Institutional review board approval and informed consent were obtained. Patients known to have or suspected of having nonobstructive Crohn disease were recruited. Each patient underwent capsule endoscopy, computed tomographic (CT) enterography, colonoscopy with ileoscopy, and small-bowel follow-through (SBFT). Findings consistent with Crohn disease were tabulated for each imaging examination (diagnostic yield). The proportions of patients with positive findings at each examination were compared, and any significant differences between the tests were calculated by using the exact McNemar test. Result: Seventeen patients (nine women, eight men; mean age, 48 years; range, 18-78 years) completed the study out of 20 patients enrolled. Crohn disease was depicted by capsule endoscopy in 12 patients (71%), ileoscopy in 11 (65%), CT enterography in nine (53%), and SBFT in four (24%). Ileoscopy was incomplete in four patients, and capsule endoscopy was incomplete in two patients. Capsule endoscopy had the highest diagnostic yield for Crohn disease, and SBFT had the lowest, but these differences were not statistically significant (P = .02). SBPT failed to depict stricture in one patient, which resulted in surgical removal of the capsule. CT enterography and SBPT depicted a extraintestinal findings (eg, mesenteric adenopathy in two patients, perianal and enterocolic fistulas in one patient) not detected endoscopically. Conclusion: This preliminary study demonstrates capsule endoscopy and CT enterography may depict nonobstructive Crohn disease when techniques such as ileoscopy and SBFT have negative or inclusive findings.
