中文摘要：

目的评价两种不同肠道准备方法对电子结肠镜检查结果的影响，寻求更为安全、有效的清洁肠道的方法。方法将568例行结肠镜检查的患者随即分为观察组（286例）和对照组（282例），观察组口服潘泻叶煎剂、对照组口服甘露醇溶液，分别观察各组患者的肠道清洁度、药物的不良反应、并发症及检查成功率。结果观察组肠道的清洁效果优良、电子结肠镜检查成功率100％，不良反应发生率28．67％，并发症发生率0；对照组电子结肠镜检查成功率90．07％，不良反应发生率42．55％，并发症发生率3．54％，两组结果比较差异具有显著性意义（均P〈0．01）。结论采用潘泻叶煎剂口服清洁肠道较甘露醇更为安全、有效、检查成功率高，电子结肠镜检查前行肠道准备时可作为首选方法。

英文摘要：

Objective To evaluate the effect of two different ways of enteric preparation for electronics colonoscopy in order to explore a way of more safe and effective. Method 568 patients progressed colonoscopy were randomly divided into two groups. 286 in observation group, 282 in control group. Peroral senna leaf decoction was used in the observation group, while manicol solution was used in control group. The difference of their enteric cleaning degree, medicine adverse reaction complication and examining successes rate were observed and compared between the two groups. Result The enteric cleaning degree in observation group is better, the electronics colonoscopy examining success rate is 100%, adverse reaction rate is 28.76%. The complication is 0. To the control group, the figure is 90.07%, 42.55% and 3.54% respectively. The comparison of the two groups is significant difference （P〈0.01）. Conclusion Using peroral senna leaf decoction to clean the intestinal canal is more safe, effective and higher exami- ning success rate than that of using mamieol, It could be the first choice while being progressed enteric preparation before electronics colonoscopy.
