Abstract: Enhanced recovery after surgery (ERAS) refers to a series of perioperatively optimized interventions based on evidence-based medicine, to reduce surgical stress and accelerate postoperative recovery of patients. The basic principles of ERAS include preoperative counseling, elimination of routine bowel preparation, preoperative carbohydrate uploading, multimodal analgesia, intraoperative temperature monitoring, optimized fluid infusion, avoidance of drainage placement, early postoperative feeding and ambulation. Studies have shown that ERAS can significantly shorten the length of hospital stay, reduce perioperative complications, save hospitalization expenditure, improve the patient's life quality, and may benefit patients in the long term. The successful implementation of ERAS requires combined efforts of multiple disciplines to develop a standard protocol for clinical practitioners, while the actual situation of each medical center and the specific condition of each patient should be fully investigated to achieve individualization and optimization at the same time.
