提高胶囊内镜检查质量的补救方法研究

目的胶囊内镜检查时,部分患者胶囊进入小肠后发现肠道清洁度较差,本研究拟通过采取补救清肠法,以期提高胶囊内镜检查的成功率及肠道清洁度。方法 90例患者随机分为A组(100 mL甘露醇+200 mL温水)、B组(50 mL甘露醇+100 mL温水)和C组(100 mL温水)3组,比较患者采取补救措施后全小肠检查完成率及肠道清洁度。结果 A组和B组的患者肠道清洁度明显优于C组,A、B两组患者肠道清洁度与C组比较,差异有统计学意义(P<0.05)。全小肠检查率A组为100%(30/30),B组为90%(27/30),C组70%(21/30)。结论采用50 mL甘露醇+100 mL温水进行补救清肠的方法,肠道清洁度好,全小肠检查完成率高,是较为理想的补救清肠方法。

Optimal bowel preparation supplementary methods on capsule endoscopy

Objective To study the effects of different bowel preparation supplementary methods on cleanness of colon and passage time in capsule endoscopy.Methods 90 cases underwent capsule endoscopy were divided into three groups randomly: group A(100 mL mannito+200 mL warm water),group B(50 mL mannito+100 mL warm water),group C(100 mL warm water).The efficacy of bowel preparation supplementary methods were evaluated based on complete rate and image sharpness of small bowel.Results The cleanness of colon in group A and group B were better than group C and the difference was significant(P<0.05).The complete rate were 100%(30/30),90%(27/30) and 70%(21/30) respectively.Conclusion The method of group B(50 mL mannito+100 mL warm water) is an optimal bowel preparation supplementary methods on patients whose bowel are not clean after preparation.
