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.
