Abstract: The increasing aging population in our country leads to the raise of the number of elderly patients undergoing surgical procedures. Elderly patients are characterized with conditions such as multiple comorbidities, high nutritional risk, frailty, decreased organ function. Nutritional support is an important part in the perioperative period of elderly surgical patients. Currently, there is a lack of guidelines or expert consensus on nutritional support both domestically and interna-tionally. To promote the development of work in this specific field, based on existing research evidence, the Geriatric Surgery Professional Committee of Chinese Research Hospital Association gathers experts to formulate the Chinese Expert Consensus On Perioperative Nutritional Support For Elderly Surgical Patients (2024 Edition). This consensus includes several parts: preoperative nutritional assessment, indications, goals, ingredients and approaches, nutritional complications and management of pre-operative and postoperative nutritional support therapy, nutritional intervention for surgical compli-cations, and nutritional follow‑up. The consensus aims to provide valuable suggestions for standardi-zing nutritional support for elderly surgical patients.
