一、对于分型的认识:急性胰腺炎通常分为水肿型及(出血)坏死型。前者为轻型,很常见,预后良好。后者为重型,远较少见,约占3～5%,病情险恶,并发症多,病死率30～50%或更高。由于两型预后悬殊,治疗措施不尽相同,临床上根据病情将其区分为两型,确有其优越性和必要性。但是,另一方面也必须看到,两型的病理基础并无区别,仅是各种病变的严重程度不同。水肿型以间质水肿为主,坏死无或轻微,无明显血管破坏;而坏死型则在水肿基础上并有明显坏死,或有明显出血则为出血坏死型。以上系由轻到重的一系列病理演变过程,不能截然分 First, the understanding of typing: acute pancreatitis is usually divided into edema and (bleeding) necrosis type. The former is light, very common, the prognosis is good. The latter is heavy, far less common, accounting for 3 to 5%, the risk of serious illness, complications, mortality 30 to 50% or more. Due to the poor prognosis of the two types, the treatment is not the same, according to the clinical condition will be divided into two types, does have its advantages and necessity. However, on the other hand, it must also be noticed that there is no difference between the two types of pathological basis, only the severity of the various pathological changes. Edema-based interstitial edema-based, no necrosis or mild, no significant vascular damage; and necrosis in the edema on the basis of significant necrosis and there, or obvious hemorrhagic bleeding was necrosis type. Above a series of pathological changes from light to heavy weight, can not be completely divided
