Abstract: ［Abstract］ Objective To explore the preoperative application of enteral nutrition as intestinal preparation of perioperative period in elderly with colorectal cancer under the concept of enhanced recovery after surgery（ERAS）. Methods The clinical data of 56 elderly patients with colorectal cancer were retrospectively analyzed. The patients were divided into enteral nutrition group and control group according to different preoperative bowel preparation. In the enteral nutrition group, an oral enteral nutrient suspension were administered preoperatively, while traditional treatment methods were used in the control group. The efficacy and postoperative complications were observed and compared. Results The related indicators such as the operation time and total length of hospital stay were similar in the two groups, and no serious complications such as anastomotic leak and abdominal infection were found. The intestinal cleanliness and postoperative nutritional indicators in the enteral nutrition group were better than those in the control group（P<0.05）. There was no significant difference in adverse reactions during bowel preparation between these two groups. Conclusion Preoperative preparation by using enteral nutrition in elderly patients with colorectal cancer is safe and feasible, and avoids the shortcomings of traditional methods, and is good for the perioperation period.

摘要： ［摘要］ 目的 探讨采用肠内营养作为肠道准备对老年大肠癌术后早期康复的影响。方法 回顾性分析 56 例老年结直肠癌患者的临床资料，按照术前肠道准备的不同分为肠内营养组和对照组。肠内营养组术前口服肠内营养混悬液，对照组则采用传统治疗方法（普通流质食物）， 观察比较两组疗效及术后并发症。结果 两组手术时间、总住院时间等相关指标接近，均未发现吻合口漏及腹腔感染等严重并发症。肠内营养组患者术中肠道清洁度及术后营养指标均优于对照组，差异有统计学意义（P<0.05），两组患者肠道准备期间不良反应无显著差异。结论 老年结直肠癌患者肠道术前准备使用肠内营养安全可行，避免传统方法的缺点，且围手术期效果良好。
