急性胰腺炎(acute pancreatitis,AP)在世界范围内是最常见的需要紧急收治入院的消化系统疾病之一,年发病率每10万人中13~45例[1]。其中急性胆源性胰腺炎(acute biliary pancreatitis,ABP)占AP年发病人数的15%~50%,死亡率高达20%~35%[2]。随着内镜治疗以微创技术逐渐取代部分传统外科手术,其应用也逐渐介入到AP的治疗中并取得了较大的进展。内镜下逆行胰胆管造 Acute pancreatitis (AP) is one of the most common digestive diseases requiring emergency admission and treatment in the world, with an annual incidence of 13 to 45 cases per 100,000 people [1]. Among them, acute biliary pancreatitis (ABP) accounts for 15% -50% of the annual incidence of AP and the mortality rate is as high as 20% -35% [2]. With the endoscopic treatment with minimally invasive techniques to gradually replace some of the traditional surgical procedures, its application is gradually involved in the treatment of AP and made great progress.
