Abstract: Neonatal necrotizing enterocolitis (NEC) is the most common intestinal disease leading to neonatal mortality，with 20% -50% of patients requiring surgical intervention. Short bowel syndrome is one of the most serious complications after NEC surgery. Nutritional management affects postoperative recovery. Despite the development of pediatric nutritional skills，nutrition -related complications such as electrolyte disturbances，nutrient imbalances，and parenteral nutrition associated liver disease still exist. This article aims to describe the aspects of postoperative nutritional assessment，nutrition modality selection and complication prevention of NEC postoperative nutrition management，and then provide theoretical support for nutritional treatment and bowel function rehabilitation of NEC.

Key words: nutritional management, necrotizing enteroc-olitis, surgery, complication, intstinal function

摘要： 坏死性小肠结肠炎（NEC）是导致新生儿死亡的首位肠道疾病，其中20%～50%患儿需要外科手术干预。短肠综合征是NEC术后最严重并发症，而营养管理是术后恢复及影响预后的重要因素。尽管目前儿童营养技术不断发展，但仍存在电解质紊乱、营养素失衡、静脉营养相关性肝病等营养相关并发症。该文从术后营养评估、方式选择、并发症防治等方面阐述NEC术后营养管理，为NEC的营养治疗和肠功能康复提供理论支持。
