Abstract: Crohn's disease(CD) is a chronic,relapsing inflammatory bowel disease.Despite continuous advances in medical therapy,a subset of patients still requires surgical intervention.Postoperative nutritional management is crucial for promoting recovery,preventing complications,and reducing the risk of recurrence.This article systematically delineates four pivotal strategies for postoperative nutritional management in CD:the initiation and implementation of early postoperative enteral nutrition(EN),bridging therapy with biologics,the application of Supplemental Enteral Nutrition（SEN）,the management of anemia and trace element deficiency following ileal resection.By integrating early EN to restore intestinal function,combining it with biologics to prevent recurrence,and supplementing with long-term nutritional support alongside systematic monitoring,prevention,and treatment of anemia and trace element deficiencies,a comprehensive strategy for postoperative nutritional management in CD is established.This approach aims to improve long-term patient outcomes and enhance quality of life.
