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.

摘要： 新生儿坏死性小肠结肠炎（necrotizing enteroc-olitis，NEC）是一种常见的新生儿急腹症，以局部肠黏膜或肠壁全层弥漫性坏死为特点，主要累及部位为末端回肠或结肠。近年来，随着NEC早期诊断、早期治疗水平的提高，NEC病死率逐年下降，但其治疗后并发症的发生率随之增加。其中肠狭窄是NEC后最常见的并发症，由于临床症状缺乏特异性，易漏诊或误诊，导致生长发育迟缓、肠穿孔、败血症等严重后果。该文将从NEC后肠狭窄的临床特点、诊断、治疗及预后等方面进行综述，旨在为NEC后肠狭窄的早期诊断及治疗提供参考依据。
