The concept of enhanced recovery after surgery (ERAS) is developed according to the evidence-based medicine. ERAS reduces the physiological and psychological stress in surgical patients. It aims at expediting postoperative recovery by implementing specific strategies in perioperative management. It optimizes the perioperative care through the multidisciplinary collaboration of surgeons, anesthesiologists, nurses and nutritionists;reduces the perioperative stress response and postoperative complications; shortens the hospital stay, and promotes the patient rehabilitation (1).
