坏死性小肠结肠炎(Necrotizingenterocolitis,简称NEC)可发生于任何年龄,但新生儿坏死性小肠结肠炎在病因、发病机制、治疗和预防等方面与儿童和青年坏死性肠炎及成人坏死性肠炎有显著的不同特点。NEC在被认为是一种独立疾病以前,曾被诊断为新生儿小肠梗塞、腹膜炎、胰腺炎、非特异性胃肠穿孔、缺血性小肠炎、新生儿败血症、新生儿颅内出血等。本病病死率高,尚有许多问题有待解决,今后须进一步研究。病因及发病机制 NEC被认为是一种特殊疾病虽为时 Necrotizingenterocolitis (NEC) can occur at any age, but Neonatal necrotizing enterocolitis is significantly associated with childhood and young necrotic enteritis and adult necrotic enteritis in terms of etiology, pathogenesis, treatment and prevention Different characteristics. NEC was diagnosed as neonatal intestinal obstruction, peritonitis, pancreatitis, non-specific gastrointestinal perforation, ischemic enterocolitis, neonatal sepsis, neonatal intracranial hemorrhage and so on until it was considered an independent disease. The disease fatality rate, there are still many problems to be solved in the future to be further studied. Etiology and pathogenesis NEC is considered a special disease though
