目的研究大肠癌病人术前管饲全肠内营养的效果及其肠道清洁的作用。方法对2004年1~12月收治的40例大肠癌病人随机分为两组(各20例),试验组术前予管饲全肠内营养7d;对照组行传统肠道准备。比较两组在血清蛋白、术中肠清洁度、术后感染性并发症发生及肠道功能恢复时间等方面的差异。结果试验组术前1d和术后7d血清白蛋白、前白蛋白、转铁蛋白均高于对照组,肛门排气时间则短于对照组(P<0·01),两组差异有显著性。但两组术中肠道清洁度、住院天数和术后感染性并发症发生率差异无显著性意义。结论大肠癌病人术前应用管饲全肠内营养能获得有效的营养支持和肠道清洁,该方法可替代大肠癌术前传统的肠道准备。
Objective To study the effect of preoperative gavage and enteral nutrition in patients with colorectal cancer and the role of gut cleaning. Methods Forty patients with colorectal cancer who were admitted from January to December 2004 were randomly divided into two groups (n = 20 each). The experimental group was given gavage for 7 days before operation and the control group was given traditional gut preparation. The differences of serum protein, intraoperative intestinal cleanliness, postoperative infectious complications and intestinal function recovery time were compared between the two groups. Results The levels of serum albumin, prealbumin and transferrin in the experimental group were significantly higher than those in the control group at 1 day and 7 days after operation, and the time of anal exhaust was shorter than that of the control group (P <0.01). There was significant difference between the two groups . However, there was no significant difference in the incidences of postoperative intestinal cleanliness, hospitalization days and postoperative infectious complications between the two groups. Conclusion Colorectal cancer patients preoperative application of tube feeding total enteral nutrition to obtain effective nutritional support and intestinal clean, the method can replace the preoperative bowel preparation for colorectal cancer preoperative.
