超声在NEC诊断中的应用进展

Application of ultrasound in the diagnosis of NEC

坏死性小肠结肠炎(necrotizing enterocolitis,NEC)是影响新生儿胃肠道的最常见、最致命的疾病。目前公认的NEC临床分期指南是改良版Bell分期,其中腹平片(X线)是影像学的金标准,然而X线有很大的局限性,造成内科对NEC早期诊断以及外科对手术时机地选择成为挑战。超声在NEC诊断中存在优势,得到临床的广泛认可,现对NEC的超声表现进行综述。

Necrotizing enterocolitis(NEC)is the most common and fatal disease affecting the function of gastrointestinal tract ofin newborns.At present,the generally accepted clinical staging guide of NEC is the modified version of Bell staging,in which abdominal plain film(X-ray)is the gold standard of imaging.However,X-ray has great limitations,which makes it a challenge for internal medicine to make early diagnosis of NEC and surgery to choose the timing of operation.Ultrasound has advantages in the diagnosis of NEC and has been widely recognized in clinic.In this paperarticle,the ultrasonographic findings of NEC arewere reviewed.
