【Abstract】：Acute pancreatitis (AP) is a common emergency. Most patients with AP run a benign course, while up to 20% develop to severe acute pancreatitis with high mortality rate. As a result, it’s crucial to identify high risk patients and give them early appropriate treatments. This article will review and compare the characteristic of Ranson, APACHE II, BISAP, CTSI scoring systems, which are widely used to differentiate mild acute pancreatitis from severe acute pancreatitis, and predict mortality rate.
