【摘要】 目的 探讨结、直肠癌术前使用肠内营养制剂代替传统流质饮食进行肠道准备的可行性与效果。方法 结、直肠癌择期手术病人40例,随机分为两组。实验组20例,术前3天口服能全素作术前肠道准备；对照组20例,采用传统流质饮食，然后比较两组的肠道清洁度、术后并发症及各项营养评定指标。结果 两组病人肠道清洁度均较好。实验组术后电解质失衡及感染并发症发生率均略低于对照组，但差异无显著性意义(P>0.05)。实验组的营养指标在肠道准备前与术后无显著性差异，而对照组术后血清总蛋白、清蛋白、前清蛋白和转铁蛋白均较肠道准备前降低(P<0.05)。结论 采用肠内营养制剂代替传统流质饮食进行术前肠道准备，能保证良好的肠道清洁度，改善患者营养状态，减少术后的并发症。
