急性胰腺炎(acute pancreatitis,AP)是消化系临床常见急腹症之一,临床上分为轻症急性胰腺炎(mild acute pancreatitis,MAP)和重症急性胰腺炎(severe acute pancreatitis,SAP).其中重症急性胰腺炎是一种发病急、进展快、并发症多、治疗棘手的常见危重急腹症。文献报道,AHNP的病死率高达40%～70%[1]。因此,要降低其病死率,提高重症急性胰腺炎的早期诊断是关键之一。用于判断AP严重程度的方法很多,包括各种评分系统、生化指标以及影像学方法等.本文就重症急性胰腺炎的诊断进展总觉如下。 Acute pancreatitis (AP) is one of the common clinical acute digestive diseases in the digestive system and is divided into mild acute pancreatitis (MAP) and severe acute pancreatitis (SAP) Severe acute pancreatitis is a rapid onset, rapid progress, complications, and treatment of acute critical acute abdomen. Reported in the literature, AHNP mortality rate as high as 40% to 70% [1]. Therefore, to reduce its mortality, improve the early diagnosis of severe acute pancreatitis is one of the key. There are many ways to judge the severity of AP, including various scoring systems, biochemical indicators and imaging methods, etc. The diagnosis of severe acute pancreatitis in this article is as follows.
