Abstract:
We aimed to assess the correlation between computed tomography enterography ( CTE ) and balloon‐assisted enteroscopy on severity of small bowel lesions, and evaluated the accuracy of CTE parameters in assessing small intestine lesions in patients with C rohn's disease ( CD ). Methods We performed an observational study of a single‐center cohort. Data were retrieved from our inpatient databases starting from O ctober 2007. Correlations between computed tomography parameters (bowel wall thickness, mural enhancement, comb sign, extramural findings, and stricture), endoscopic and histological severity scores, CD Activity Index [ CDAI ], and C‐reactive protein were assessed using Spearman's rank correlation. Results Seventy patients were included in this study. One hundred fifty‐seven segments were examined. Bowel wall thickness (r = 0.6334, P 〈 0.0001), mural enhancement (r = 0.5477, P 〈 0.0001), comb sign (r = 0.5898, P 〈 0.0001), and extramural findings (r = 0.4754, P 〈 0.0001) were moderately correlated with the segmental Capsule Endoscopy CDAI . The segmental CTE score also moderately correlated with the segmental Capsule Endoscopy CDAI (r = 0.6714, P 〈 0.0001), while the total CTE score strongly correlated with the total Capsule Endoscopy CDAI (r = 0.7252, P 〈 0.0001). Both total CTE score (r = 0.5937, P 〈 0.0001) and total Capsule Endoscopy CDAI (r = 0.6364, P 〈 0.0001) correlated significantly with the H arvey– B radshaw Index. Of five computed tomography parameters, bowel wall thickness have the best accuracy to detect small intestine lesions with an area under the receiver operating characteristic curve of 0.811 ( P 〈 0.0001), with a sensitivity and specificity of 81.82% and 74.14%, respectively. Conclusion CTE is a reliable technique for detecting small intestine lesions in patients with CD , also provides accurate information on small bowel CD severity and activity, with close agreement to inflammatory markers, CDAI , and histopathology.
