Enhanced recovery after surgery(ERAS) has been a hot research topic of modern surgery, and the core of ERAS is based on a high level evidence-based medicine, aiming to reduce the influence of surgical trauma and stress on patients, reduce the risk of postoperative complications, shorten the length of hospital stay and reduce hospitalization expenses. Perioperative nutrition, especially in enteral nutrition intake is particularly important for the prognosis of patients. This paper summarized the clinical research progress of enteral nutrition, especially oral nutritional supplement, in fast-track surgery for colorectal cancer and to provide reference and basis for its safety and implementation strategy. (术后加速康复是现代外科的研究热点, 其核心理念是基于高水平的循证医学证据, 减少患者的手术创伤和应激, 从而减少术后并发症, 缩短住院时间, 减少住院费用, 而围术期营养特别是肠内营养的摄入对患者的预后具有特别重要的意义。本文总结了目前关于结直肠癌加速康复外科肠内营养实施的临床研究进展, 为其安全性和实施策略提供参考和依据。)
