摘　　要：仅胰周坏死型胰腺炎(EXPN)是指仅累及胰腺周围脂肪组织/细胞坏死,而胰腺实质未见确切坏死的一种急性坏死性胰腺炎的独立亚型。EXPN的严重程度及预后介于急性间质水肿性胰腺炎与胰腺实质坏死(伴或不伴有胰周坏死)两者之间,且其累及范围也是影响该病严重程度及预后结局的重要因素。因此,正确认识及诊断EXPN,为临床提供适宜的干预依据,对提高病人预后、降低病人死亡率具有重要意义。就EXPN的定义、流行病学、影像表现及预后予以综述。Extrapancreatic necrosis alone(EXPN)is an independent subtype of acute necrotizing pancreatitis manifesting only extrapancreatic adipocyte/tissue necrosis,without definite necrosis in the pancreatic parenchyma.The severity and prognosis of EXPN are between acute interstitial edema pancreatitis and pancreatic parenchymal necrosis(with or without extrapancreatic necrosis),and the extent of EXPN involvement is an important factor affecting the severity and prognosis of the patients.Therefore,it is of great significance to correctly recognize and diagnose EXPN and provide evidence for clinicians to start appropriate interventions,and consequently to improve the prognosis and reduce the mortality.In this paper,we reviewed the definition,epidemiology,imaging findings and prognosis of EXPN.
