摘　　要：目的探讨在肠道注气状态下胶囊内镜的小肠黏膜观察效果，以期进一步提高小肠疾病的检出率。方法2011年11月至2012年4月，将解放军总医院消化科行胶囊内镜检查患者，采用随机数字表法分为注气干预组（n=14）和常规检查组（n=13），对比分析全小肠检查完成率和阳性发现率、胶囊内镜在小肠的转运时间、小肠清洁程度和展开程度。结果注气干预组与常规检查组在全小肠检查完成率[85．71％（12／14）比61．54％（8／13），P=0．209]和疾病阳性发现率[71．43％（10／14）比84．62％（11／13），P〉O．05]方面，差异均无统计学意义。注气干预组的小肠通过时间为（270．86±144．85）min，较常规检查组的（325．15±161．76）min有所缩短，但差异无统计学意义（P=0．369）。注气干预组整体肠道清洁程度好于常规检查组[（2．05±0．40）分比（1．75±0．40）分]，差异亦无统计学意义（P=0．060）。注气干预组整体肠腔展开程度明显好于常规检查组[（1．79±0．40）分比（1．38±0．29）分]，差异有统计学意义（P=0．004）。结论注气干预胶囊内镜检查，可以显著提高小肠黏膜展开程度，并有提升小肠整体清洁度及缩短全小肠工作时间的趋势。Objective To investigate the effect of capsule endoscopy on the small intestinal mucosa in the state of air insufflation. Methods Patients undergoing capsule endoscopy from November 2011 to April 2012 were divided into the air insufflation intervention group （n = 14） and routine examination group （n= 13） by random number table method. The detection rate of small bowel disease, the transit time of capsule endoscope in small intestine, the degree of intestinal cleaning and the degree of intestinal lumen expansion were compared between two groups. Results There was no significant difference in total intestinal examination rate [ 85.71% （12/14） VS 61.54% （ 8/13）, P = 0. 209] or disease detection rate [ 71.43% （10/14） VS 84. 62% （11/13）, P〉 0. 05 ] between air insufflation intervention group and conventional examination group. The mean procedure time of the air insufflation intervention group was 270. 86 ± 144. 85 min, which was shorter than that of the conventional examination group （325.15 ± 161.76 min, P= 0. 369）. The overall cleanliness of the air insufflation intervention group was higher than that of the conventional examination group （ 2.05 ± 0.40 VS 1.75±0. 40, P = 0. 060）. The overall degrees of expansion of small intestine lumen were 1.79 ± 0. 40 and 1.38 ± 0. 29 scores, respectively （ P = 0. 004 ）. Conclusion Capsule endoscopy can significantly improve the degree of intestinal lumen expansion with trend of improving the overall cleanliness of the small intestine, and shortening the working time of the small intestine.
