胶囊内镜与双气囊小肠镜对小肠疾病诊断价值的研究

【摘要】  　　目的 比较胶囊内镜、双气囊小肠镜对疑诊小肠病变的诊断价值。方法 按检查方式将疑诊小肠病变患者分为两组，即胶囊内镜检查组，双气囊小肠镜检查组，分析统计各组病变检出情况，计算检出率，阳性率。同时分析部分病例进行胶囊内镜结合双气囊小肠镜检查的病变一致率。结果 胶囊内镜组检出率 89.1 %（49/55），阳性率60 %（33/55）；双气囊内镜组检出率 76.9 %（103/134），阳性率 69.4 %（93/134）。两组比较差异无统计学意义（P＞0.05）。同时进行胶囊内镜和双气囊小肠镜检查的9例患者中，发现胶囊内镜假阴性率为11.1%（1/9），胶囊内镜阳性结果经小肠镜证实率为62.5%（5/8）。所有患者均未出现出血、穿孔、过敏、胶囊滞留等严重并发症。结论 双气囊小肠镜与胶囊内镜对小肠病变均有较高的检出率与阳性率，在本试验中无明显差异。两种方法的结合可提高小肠病变的检出，在临床实践中，可灵活选用。

　　［Abstract］  Objective  To compare the diagnostic value of double balloon endoscopy for small intestinal disease with capsule endoscope.Methods  According to the checking method,the patients with susceptible small intestinal disease were divide into 2 groups the double balloon endoscopy group and the capsule endoscopy group. To analyze the detectable rates ,the positive rates and the concordance rates of some patients combining double balloon endoscopy with the capsule endoscopy. Results  The detectable rates for double balloon endoscopy was 76.9 %（103/134） , and 89.1 %（49/55） for capsule endoscopy. The positive rates of double balloon endoscopy was 69.4 %（93/134） , and 60 %（33/55） for capsule endoscopy. Significant difference was not seen between the two groups （P>0.05）. The false-negative rates of capsule endoscopy in the 9 patients combining double balloon endoscopy with the capsule endoscopy was 11.1% （1/9）.The comfirmation rates of capsule endoscopy positive findings through double balloon endoscopy was 62.5% (5/8).No severe complication such as bleeding 、perforation、allergy、capsule retention and
