摘　　要：目的:比较胶囊内镜、小肠气钡双重造影及磁共振小肠造影3种检查方法在小肠疾病中的诊断效果。方法:选取26例怀疑为小肠病变的就诊者,采用胶囊内镜和小肠气钡双重造影检查,14例加做磁共振小肠造影,同时选取13例排除小肠疾病的就诊者作为对照。分别计算3种检查方法诊断小肠疾病病因的符合率、灵敏度、特异度等指标,并进行组间比较。结果:胶囊内镜、小肠气钡双重造影及磁共振小肠造影,对病因诊断三者的符合率分别为87.18%、64.10%、51.85%,灵敏度分别为84.62%、57.69%、42.86;符合率、灵敏度和阳性预测值的组间比较差异均有统计学意义(χ2=10.258,P=0.006;χ2=8.040,P=0.018;χ2=8.739,P=0.012)。结论:胶囊内镜的诊断效果优于小肠气钡双重造影及小肠磁共振造影检查,值得推广使用,后两者的诊断效果无差异。Objective ： To compare the effieaeies of capsule endoscopy, mr-barium double-contrast radiography and angiography by magnetic resonance im- aging（MRI） in the diagnosis of small bowel disease. Methods：Twenty-six patients with suspected small bowel disease were included, and underwent cap- sule endoscopy and small bowel air-barimu double contrast radiography. Of the 26 patients, 14 received additional angiography for the small bowel by MRI. Another 13 patients undergone screening of small bowel lesions were included as controls. Then the coincidence rate, sensitivity and specificity were calcu- lated and compared among the three techniques and groups. Results：The coincidence rate and sensitivity was 87.18%, 64.10% and 51.85%;84.62%, 57.69% and 42.86, respectively. The dift）rence was significant among the coincidence rate, sensitivity and positive prediction value among the three groups （ x^2= 10.258, P= 0.006 ; x^2= 8.040, P = 0.018 ; x^2= 8.739, P = 0.012, respectively）. Conclusion ： Capsule endoscopy is superior to air-barium double-con- trast radiography and MRI angiography in diagnosis of small bowel lesions, yet the latter two techniques remain no significant difference in diagnostic efficacy.
