Abstract:
Objective To investigate the value of double-balloon endoscopy (DBE) and multi-slice CT enteroclysis (MSCTE) in diagnosis of Crohn's disease (CD) in small intestine. Methods DBE and MSCTE were performed in 71 patients with suspected Crohn's disease in small intestine. The two methods were compared in terms of diagnosis, extents of disease, existance of complications and activity of the disease according to the pathologic findings and the outcome of follow-up. Results The diagnostic yields of DBE and MSCTE were comparable with no significant difference (χ2=2.29, P> 0.05). The positive and negative likelihood ratios were 22.5 and 0. 022 in DBE respectively, and were 1.6 and 0. 240 in MSCTE respectively. The results of DBE was consistent with MSCTE in diagnosis of mild bowel stenosis, but was inconsistent with MSCTE in diagnosis of moderate-severe bowel stenosis (χ2=11.298, P=0.001). The concordance of two methods in diagnosis of disease activity was 95.8%. Conclusions The first choice in diagnosis of small bowel CD is DBE. The combination of two methods will be helpful in diagnosis and evaluation of CD severity.
