有营养风险的老年结直肠癌患者术前肠内营养的临床研究

摘要

目的 观察有营养风险的老年结直肠癌患者术前肠内营养对患者术后营养状况、免疫功能及并发症的影响.方法 运用NRS2002营养风险筛查标准,选择重庆医科大学附属永川医院60岁以上有营养风险的老年结直肠癌患者70例,分为肠内营养组(EN组)36例,对照组34例.EN组术前3d给予肠内营养支持,术后第1、3、5、7天检测血浆总蛋白、前清蛋白、清蛋白、转铁蛋白、淋巴细胞总数、血浆D-乳酸(D-LAC)和二胺氧化酶(DAO),观察术中肠道清洁度、术后并发症.结果 EN组术后第1、3、5、7天的血浆总蛋白、前清蛋白、清蛋白、转铁蛋白及淋巴细胞总数均明显高于对照组;D-LAC、DAO水平及腹腔感染、伤口感染等感染性并发症的发生率明显低于对照组,差异有统计学意义(P＜0.05);两组在肠道清洁度、吻合口漏发生率上差异无统计学意义(P＞0.05).结论 有营养风险的老年结直肠癌患者术前肠内营养支持治疗可明显改善临床预后.%Objective To observed the influence of preoperative enteral nutrition(EN) on postoperative nutritional status,immune function and complications in elderly patients with colorectal cancer complicating nutritional risk.Methods The NRS2002 nutritional risk screening criteria was used to select 70 elderly patients with colorectal cancer complicating nutritional risk,including 36 cases in the EN group and 34 cases in the control group.The EN support was given in the ENN group on preoperative 3 d.The levels of plasma total protein,prealbumin,albumin,transferrin,total lymphocyte count,plasma D-lactate(D-LAC) and plasma diamine oxidase (DAO) were detected on postoperative 1,3,5 7 d.The intraoperative intestinal cleanliness and postoperative complications were observed.Results The levels of plasma total protein,prealbumin,albumin,transferrin and total lymphocyte count in the EN group were significantly higher than those in the control group and the levels of D-LAC and DAO,and the incidence rates of abdominal infection and wound infection were significantly lower than those in the control group,the differences were statistically significant(P＜0.05).There was no statistically significant differences in the incidence rates of intestinal cleanliness and anastomotic leakage between the two groups (P＞0.05).Conclusion Preoperative EN support therapy in the patients with colorectal cancer complicating nutritional risk can significantly improve clinical prognosis.
