Based on evidence-based medicine, ERAS optimizes clinical pathways involving perioperative management through the collaboration of multiple departments, including surgery, anesthesia, nursing, and nutrition, to reduce postoperative complications, shorten hospital stays, and promote recovery by alleviating various perioperative stresses in patients. This optimized clinical pathway runs through the entire treatment process before hospitalization, before surgery, during surgery, after surgery and after discharge, and its core emphasizes the patient-centered treatment concept.

• Reducing pain and discomfort

• Reduce the risk of complications in all treatment modalities

• Faster achievement of optimal nutritional targets during treatment

• Shorter hospital stays and lower treatment costs

• Maintain optimal nutritional and metabolic status at home

• Improved exercise capacity and mental status

• Early return to a healthy life
