Abstract: Nutritional support therapy can improve to the postoperative nutritional status and quality of life of patients with digestive tract malignancies. Clinical guidelines at home and abroad recommend early preoperative nutritional support therapy based on oral nutrition supple-mentation for patients undergoing surgery for digestive tract malignancies to reduce the risk of malnutrition. Enteral nutrition powder is the main perioperative nutritional support method for patients with basically normal gastrointestinal function. At present, many Meta‑analyses also point out that early postoperative nutrition can effectively enhance the body′s immunity, reduce post-operative complications and shorten the length of hospital stay. However, the analysis of short‑term outcome indicators is not comprehensive, and there is no summary analysis result on Chinese patients. The authors review the relevant literatures and conduct a Meta‑analysis to evaluate the effect of enteral nutrition powder on the short‑term postoperative outcomes of Chinese patients with digestive tract malignancies.
