Effect of early enteral nutrition after total gastrectomy on nutritional status and hospitalized recovery of elderly patients with gastric cancer

  • 摘要: 目的 探讨全胃切除术后早期肠内营养(EN)对高龄胃癌患者营养状况和住院恢复进程的影响。 方法 选取接受全胃切除术的88例高龄胃癌患者作为研究对象,采用随机数表法分为对照组和研究组,每组44例。对照组术后给予肠外营养(PN)支持,研究组术后给予早期EN支持,均维持7 d后开始经口正常饮食。检测2组患者术前和术后7 d的营养学指标血清白蛋白(ALB)、前白蛋白(PA)和血红蛋白(Hb)水平,比较2组术后首次排气时间、首次排便时间、进半流质食物时间、住院时间和并发症发生情况。 结果 对照组术后7 d血清ALB、Hb水平较术前显著下降(P<0.05), 研究组术后7 d血清ALB、Hb水平与术前相比,差异无统计学意义(P>0.05), 研究组术后7 d血清ALB、Hb水平显著高于对照组(P<0.05); 2组住院时间比较,差异无统计学意义(P>0.05); 研究组术后首次排气时间、排便时间和进半流质饮食时间早于对照组,并发症发生率2.27%低于对照组18.18%, 差异均有统计学意义(P<0.05)。 结论 高龄胃癌患者全胃切除术后接受早期EN, 能明显改善机体营养状况,加快住院恢复进程,减少并发症发生。

     

    Abstract: Objective To investigate the effect of early enteral nutrition(EN)after total gastrectomy on nutritional status and hospitalized recovery of elderly patients with gastric cancer. Methods A total of 88 elderly patients with gastric cancer who underwent total gastrectomy were selected as study objects, and were randomly divided into control group and study group, with 44 cases in each group. The control group was given parenteral nutrition(PN)support after operation, and the study group was given early EN support after operation. All of the patients maintained their treatments for 7 days and then transferred to normal oral diet. The nutritional indicators such as levels of serum albumin(ALB), prealbumin(PA)and hemoglobin(Hb)were measured before operation and 7 days after operation in the two groups. The time to first exhaust and defecation, the time to semifluid food intake, hospitalization time and the occurrence of complications were compared between the two groups. Results The levels of ALB and Hb in the control group were significantly lower at 7 d after operation compared with operation before(P<0.05), no significant differences in the above indexes were found in the same time point in the study group(P>0.05), the observation group was significantly higher in above indicators than those in the control group at 7 d after operation(P<0.05). There was no significant difference in hospitalization time between the two groups(P>0.05). The time to first exhaust and defecation, time to semifluid food intake in the observation group was shorter than that in the control group, and the complication rate was lower than that in the control group(2.27% vs. 18.18%), the differences were statistically significant(P<0.05). Conclusion Early - EN can improve the nutritional status of elderly patients with gastric cancer after total gastrectomy, promote the recovery of hospitalization and reduce complications.
