[摘要]目的 探讨聚乙二醇电解质散联合乳果糖口服液在老年便秘患者结肠镜检查肠道准备中的应用效果。方法 收集2016年5～12月在我院接受电子结肠镜检查的老年患者150例，分为聚乙二醇电解质散组、乳果糖组及实验组(聚乙二醇电解质散联合乳果糖口服液)。观察三组患者肠道准备的不良反应；患者耐受情况；肠镜检查时肠道清洁度。结果 三组不良反应发生率、在规定时间内肠道准备完成情况、肠道准备耐受度及肠道清洁程度差异均有统计学意义(均P<0.05)，三组肠镜检查成功(肠镜达到回盲瓣)率差异无统计学意义(P>0.05)。结论 对老年便秘患者采用乳果糖口服液联用复方聚乙二醇电解质散进行肠道准备，可提高患者对肠镜检查的依从性，该方法安全有效，是一种较好的肠道准备方法。
