Abstract: The textbook outcome is a novel surgical concept introduced in recent years,integrating various indicators such as postoperative complications,ICU and hospital stays,short-term readmissions,perioperative mortality,and radical resection.It provides a more comprehensive and objective reflection of surgical quality and patient prognosis.For patients at nutritional risk or with malnutrition,a holistic nutritional management approach spanning the entire perioperative period——preoperative,intraoperative,postoperative,and post-discharge——can effectively improve nutritional status,enhance 〖JP3〗physiological tolerance,promote postoperative recovery,reduce complications,and improve clinical outcomes.Perioperative nutritional therapy plays a crucial role in achieving textbook outcomes in surgical patients.

Key words: nutritional therapy; perioperative period; surgery; textbook outcomes
