Acute pancreatitis is a common acute abdomen with a variety of causes and natural course.The incidence rate is increasing year by year.Some patients may develop severe acute pancreatitis,with serious complications and a high risk of death.Therefore,early prediction of the severity of the patient's condition and active treatment are beneficial to reduce the severity and mortality rate of patients and improve the prognosis of patients.In order to predict the severity of acute pancreatitis,many prediction methods have emerged in the clinic,including acute C-reactive protein,urea nitrogen,thyroid hormone,hematocrit,inflammatory factors,visceral fat area,pancreatic necrosis volume,APACHEⅡ,Ranson score,BISAP,EPIC,MCTSI,etc.This article summarizes the serological indicators,imaging methods and scoring systems that can be used to predict severe acute pancreatitis,focusing on their characteristics and limitations.
