山梨醇等3种方法在功能性便秘患者结肠镜检查前肠道准备清洁度比较及效果观察

目的:探讨山梨醇、甘露醇、番泻叶等3种方法在功能性便秘患者结肠镜检查前肠道准备清洁度比较及效果观察。方法:山梨醇组于检查前4-5h将普复舒(山梨醇)60g化入300ml温开水中,15min内饮完,接着饮温开水2 000ml,30min内饮完。甘露醇组于检查前4-5h口服20%甘露醇250ml,15min内饮完,以后每隔30min饮用5%葡萄糖氯化钠溶液糖500ml,2h内共饮用2 000ml。番泻叶组番泻叶30g+300ml开水浸泡30min,于检查前晚饮用,隔30min后,饮用5%葡萄糖氯化钠溶液糖1 500-2 000ml,1h内饮完。清肠后通过电子肠镜检查观察清肠效果。结果:山梨醇组与甘露醇组、番泻叶组肠道清洁度的差异有统计学意义(P=0.02,P=0.03)。结论:山梨醇组在功能性便秘患者结肠镜检查前肠道准备清洁度及较药物疗效明显优于甘露醇和番泻叶。
