目的：研究胃癌患者术后早期肠内营养（EN）与肠外营养（PN）的临床疗效。方法将75例行胃癌根治术患者随机分为EN组（n=40）和PN组（n=35），术后给予EN或PN营养支持7 d，比较两组恢复情况，营养指标及并发症发生率的差异。结果与PN组比较，EN组患者肠功能恢复时间[（3.63±1.35）d vs（4.69±1.30）d，P﹤0.05]和住院时间[（11.18±4.21）d vs（13.74±5.87）d，P﹤0.05]均明显缩短，两组比较差异均有统计学意义；术后第7天，EN组患者血清白蛋白和前白蛋白水平均明显高于PN组，差异有统计学意义（P﹤0.05）；两组术后并发症的发生率比较，差异无统计学意义。结论术后早期EN能明显改善胃癌患者术后的营养状况，促进患者胃肠功能恢复，缩短住院时间。“,”Objective To investigate clinical efficacy of early enteral nutrition (EN) and parenteral nutrition (PN) in patients undergoing gastric cancer operation.Methods Seventy-five patients with gastric cancer undergoing radical operation were randomly divided into two groups of EN group (n=40) and PN group (n=35). They were supported for 7 days on EN/PN after operation. Clinical outcomes, nutritional status and postoperative complication rate between the two groups were compared.Results As compared with the PN group, anus recovery exhaust time ([3.63±1.35]d vs [4.69±1.30]d,P﹤0.05), and hospitalization time ([11.18±4.21] d vs [13.74±5.87]d,P﹤0.05) was signiifcantly shorter in the EN group. The levels of albumin and prealbumin were higher in the EN group as compared with the PN group on postoperative day 7 (P﹤0.05). There were no significant differences in the postoperative complication rate of patients between EN group and PN group (P﹥0.05).Conclusion Early EN support can improve nutrition, promote gastrointestinal function recovery, and shorten hospitalization time for patients undergoing gastric cancer operation.
