摘　　要：目的通过对新生儿坏死性小肠结肠炎(NEC)X线的征象分析,提高对本病的早期诊断,加深对本病的进一步认识。方法收集我院2005年12月～2011年12月有完整资料经X线诊断的35例NEC患儿,对其X线征象做出总结分析。结果 35例新生儿坏死性小肠结肠炎患儿早期X线征象35例均有肠道动力性改变;肠壁积气21例;肝门静脉积气影5例;肠穿孔气腹7例。结论新生儿NEC早期X线征象为肠管动力性改变为主,而肠壁间积气、肝门静脉积气为NEC的特征性X线征象,而背景模糊,腹腔密度增高是腹腔渗液进行性增多的X线征象,提示NEC进展恶化的表现。因此NEC的早期诊断对治疗和评估有重要意义。Objective To analyze the X-ray manifestations of neonatal necrotizing enterocolitis （NEC） so as to improve the early diagnostic level of this disease and to further deepen the understanding of this disorder. Methods 35 children with NEC, who were diagnosed with X-ray from Dec. 2005 to Dec. 2011, with complete information, were collected in this work. The X-ray signs of these patients were analyzed. Results Of the 35 patients, all had the intestinal dynamic changes in the early X-ray signs, 21 had pneumatosis intestinalis, and 8 appeared bowel perforation, which led to pneumo- peritoneum. Conclusion Intestinal dynamic change is the principal character of early signs of X-ray in neonatal NEC. Pneumatosis intestinalis and hepatoportal gas accumulation are the characteristic X-ray signs of NEC, but the background blur is the more progressive X-ray signs for seroperitoneum that prompts the NEC progressing deterioration. So, the early diagnosis of NEC has the important meaning to the treatment and evaluation.
