摘要
目的总结分析隐源性消化道出血的病因,探讨不同检查方法的诊断价值。方法对1992年至2004年的39例经手术治疗消化道大出血临床资料进行回顾性分析。结果39例患者均有病理诊断,所有病变以良性为主58.97%(23/39),病变部位以小肠居多89.74%(35/39)。与病理结果比,选择性动脉造影诊断符合率为56%(14/25),核素扫描定位诊断符合率为38.53%(13/34),小肠插管分段气钡造影诊断符合率为22.58%(7/31),术中内窥镜诊断符合率85.71%(6/7)。结论疑难消化道大出血病变多数在小肠,以良性病变为主,术前选择性动脉造影具有较高的定性和定位诊断价值。
Objective To analyse the cause and diagnosis of obscure gastrointestinal bleeding（OGB） and evaluate the diagnostic value of different methods for OGB. Methods The causes and diagnostic methods of 39 OGB cases from 1991 to 2004 were retrospectively analyzed. Results In all cases, the pathological diagnosis and operation of OGB were verified. Among them, 58.97% （23/39） with benign lesions were the most,and lesions were mostly located in the small intestine in 35 cases（89. 74% ）. Compared with the pathological diagnosis,the coincidence rate of selective angiography was 56% （ 14/25 ） ,and the accuracy of location with radionuclide imaging was 38. 53% （13/34）. Conclusion The lesions causing OGB mostly locate in the small intestine ; most of them are benign. Selective angiography is of great value in determining the location and the character of OGB before operation .
