Currently, it is believed that the use of UST for the preoperative treatment of CD patients is generally safe and does not increase surgical complications, and it can be used for preoperative treatment of CD. However, there is still a lack of literature reporting the role of UST in preoperative optimization for CD. Semi-enteral nutrition refers to the provision of more than 50% of the energy required by the human body through enteral nutrition preparations. Semi-enteral nutrition can improve the nutritional status of patients with CD, but it does not induce remission of active disease. The treatment method of UST combined with semi-enteral nutrition can not only induce disease remission, but also improve the nutritional status of patients. Therefore, can the combined treatment regimen replace Exclusive Enteral nutrition (EEN) as a new therapy for preoperative optimization of CD? At present, there is a lack of relevant research, so this study intends to conduct a multi-center, prospective, randomized controlled trial to compare the efficacy differences between UST+semi-enteral nutrition and EEN in preoperative optimization for CD, and to clarify the preoperative optimization effect of UST combined with semi-enteral nutrition therapy.",[100],"Crohn Disease (CD)","2025-04-02",{"date":103,"type":104},"2025-04-06","ACTUAL",{"date":106,"type":104},"2024-08-01",{"date":108,"type":94},"2026-09",{"name":59,"class":6},1]
