ABSTRACT

Standardized nutritional support therapy can improve the nutrition status and surgical tolerance as well as reducing postoperative complications.The enteral nutritional support therapy is recommended as the first choice,while supplementary parenteral nutrition will be applied to the patients when enteral nutritional support therapy cannot achieve target supplement for more than 3 days.Enhanced recovery after surgery (ERAS) focuses on the optimization of preoperative managements,which also greatly update the strategy of nutritional support therapy.Risk assessment of nutrition in patients with surgery and correction of preoperative malnutrition are becoming important parts of ERAS.Preoperative nutritional support therapy not only emphasizes the energy supplement,but also regulates pathophysiologic changes of patients with surgery.It has been regarded as a mandatory method to enhance postoperative recovery and optimize preoperative managements.
