Abstract：Objective: To evaluate the diagnostic value of capsule endoscopy(CE) and computed tomography enterography(CTE) in obscure gastrointestinal bleeding. Methods: Eighty-four patients with obscure gastrointestinal bleeding were included and analyzed retrospectively in our hospital from September 2011 to December 2014. The patients were divided into three groups: CE, CTE, and combination of CE and CTE group. The diagnostic rate and diagnostic coincidence rate of the three groups were compared, and the values of CE and CTE in the diagnosis of obscure gastrointestinal bleeding were discussed. Results: Thirty-seven patients were performed CE, thirty patients of all were found to be positive for small bowel lesions, the lesion detection rate is 81.1%(30/37), and the diagnosis coincidence rate is 87.9%(29/33). Thirty-five patients were underwent CTE, and twenty-four patients of all were found to be positive for small bowel lesions, the lesion detection rate is 68.6%(24/35), and the diagnosis coincidence rate is 82.1%(23/28). Twelve patients were underwent both CTE and CE, 9 patients of all were found to be positive for small bowel lesions, the lesion detection rate is 83.3%(10/12), the diagnosis coincidence rate is 90.9%(10/11). There is no statistical significance among the three groups. Conclusion: In the diagnosis of obscure gastrointestinal bleeding, CE and CTE have high diagnostic value; the combination of the two ways can not improve the detection rate and diagnostic accuracy of the disease.
