Abstract: Necrotizing enterocolitis （NEC） in newborns is a common acute abdominal disease characterized by diffuse necrosis of the local intestinal mucosa or wall，mainly affecting the terminal ileum or colon. In recent years，with the improvement in early diagnosis and treatment of NEC，the mortality rate of NEC has been decreasing year by year，but the incidence of complications after treatment has increased. Intestinal stenosis is one of the most common complications after NEC. Due to the lack of specificity in clinical symptoms，it is easy to be missed or misdiagnosed，leading to serious consequences such as growth and development delay，intestinal perforation，and sepsis. This article will review the clinical characteristics，diagnosis，treatment，and prognosis of intestinal stenosis after NEC，aiming to provide reference for the early diagnosis and treatment of intestinal stenosis after NEC.
