摘　　要：目的 :探讨胶囊内镜以及小肠CT成像对不明原因消化道出血诊断价值。方法 :选择2011年9月—2014年12月在我院诊治的84例不明原因消化道出血病人进行回顾性研究。将患者分为3组,分别行胶囊内镜、小肠CT成像、胶囊内镜及小肠CT成像联合检查,对3组病例的病变发现率及诊断符合率进行对比,探讨胶囊内镜及小肠CT成像在不明原因消化道出血的应用价值。结果:37例行胶囊内镜检查病人,30例受检者发现小肠阳性病变,病变检出率81.1%(30/37),诊断符合率87.9%(29/33)。35例行小肠CT成像检查的病人,24例发现小肠阳性病变,病变检出率68.6%(24/35),诊断符合率82.1%(23/28)。12例行两者联合检查病人,发现小肠阳性病变10例,病变检出率83.3%(10/12),诊断符合率90.9%(10/11)。3组病例的病变检出率及诊断符合率差异无统计学意义(P>0.05)。结论:在不明原因消化道出血的诊断中,胶囊内镜和CT小肠成像均具有较高的诊断价值,两者联合不能提高病变的检出率和诊断符合率。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 is90.9%（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.
