Objective To investigate the value of capsule endoscopy in the different small intestine segments. Methods After all 53 patients accepted a strict bowel cleanning, small intestine examination was implemented completely u-sing the Israel Givens PillCamSB capsule endoscope. According to the characteristics of the small intestine lumen and the Given positioning system, the small intestine was divided into 3 sections and the cleanliness, number of lesions and lesion surface characteristics were calculated in each section. The factors that affected lesion reveals would be analyzed. Results 53 subjects had been inspection. 47 subjects finished all the small intestine observation, 10 subjects were found that the observed results were dissatisfied in some parts of the small intestine segments, accounted for 18.9% in total number of patients. Poor cleaning rate of each segment of the intestine was 30. 8% ,1.1% and 61.5% respectively. There were 42 cases found lesions in small intestine, all about 75 lesions were found in those 53 subjects. Part of the lesion surface characteristics were not well exposed. There were no significant difference in total number of lesions between the three sections of small intestine. But the percentage of non-inflammatory lesions in the three sections of the small intestine were 16.1% , 50. 0% and 33. 3% . Conclusion In the second section of the small intestine , capsule endoscopy examination get good effect, the rest sections of the small intestine will achieve better examination results, if the checking condition could be improved.%目的 探讨胶囊内镜在各段小肠中的诊断价值.方法 53例受检者行严格小肠肠道清洁,采用以色列GIVEN公司的SB胶囊内镜行全小肠检查.根据小肠肠腔特点和Given定位系统,将小肠分为3段.统计各段小肠的肠道清洁度、病变检出率和评价病灶表面特征的观察效果,对影响因素进行分析.结果 全部受检者完成检查.47例受检者完成全小肠观察,10例受检者共发现13处观察效果不佳,约占总受检病例数的18.9%;其中第1、第2和第3段小肠发现清洁欠清晰数分别为4、1和8,分别约占总数的31.8%、7.7% 和61.5%.42例受检者发现病变,共发现病灶约75处,部分病灶表面特征观察效果欠佳.3段小肠总病灶数无明显差异,但3段小肠的非炎症病灶数的百分比分别为:16.7%、50.0% 和33.3%.结论 胶囊内镜检测第2段小肠有良好观察效果及病变检出率;改进检查条件有助提高胶囊内镜在第1段和第3段小肠的诊断价值.
