Capsule Endoscopy and CT Enterography in Diagnosis of Small Intestinal Crohn's Disease / 胃肠病学

ABSTRACT

Crohn's disease (CD) of small intestine is a difficult issue in imaging examination. In recent years, capsule endoscopy (CE) has been widely used in diagnosis of CD in small intestine. Aims: To assess the value of CE and CT enterography (CTE) for clinical diagnosis of small intestinal CD. Methods: Data of 28 cases of small intestinal CD who underwent CTE and CE at the Tenth People's Hospital of Tongji University from Oct. 2014 to Apr. 2018 were analyzed retrospectively. The detection rate and diagnostic accuracy of CE and CTE were calculated and compared. Results: There was no significant difference in overall detection rate between CE and CTE (96.4% vs. 85.7%, P>0.05); but the diagnostic accuracy of CE for small intestinal CD was significantly higher than that of CTE (89.3% vs. 42.9%, P0.05). CTE is superior to CE in location and finding extraintestinal and colonic lesions. The diagnostic accuracy of combined use of CE and CTE for small intestinal CD was up to 100%. Conclusions: For diagnosis of small intestinal CD, the detection rate of CE for intestinal lesions is equal to that of CTE, while its diagnostic accuracy is superior to CTE, especially for jejunal lesions. Combined use of these two techniques is of great importance for clinical diagnosis of small intestinal CD and worthy to be used increasedly.
