以往造影前肠道准备的方法中口服缓泻剂加清洁灌肠.但近年来临床开始采用口服甘露醇做清肠准备.我们对30例患者进行了影像学的观察分析,现将总果报告如下.1 材料与方法1.1 用药:10%甘露醇250ml,淡盐水1000ml,糖水1000ml.1.2 方法:造影前1日晚8时口服250ml甘露醇,30分钟后饮水2000ml(淡盐水加糖水).2 结果与讨论2.1 口服甘露醇清肠是由于其在肠道的高渗作用,阴得了肠道内水伤的吸收.使肠组织内的部分水份进入肠道貌岸然而软化粪便,增加肠内容物的容积,促进肠蠕动而加速排便,以达到清肠的作用.在30例患者中有22例x线影像中看不到肠内容,6例有少量肠内容,只有2倒粪便排出不好.说明此方法可
