Core Tip

Core tip: The new severity criteria of acute pancreatitis (AP) consist of two independent prognostic factors; laboratory and/or clinical severity scores and contrast-enhanced computed tomography (CE-CT) findings. Mortality rate of severe acute pancreatitis (SAP) that satisfied both laboratory/clinical and CE-CT severity criteria was as high as 30.8%. It is recommended to perform CE-CT examination in those patients who were diagnosed as SAP by laboratory/clinical severity criteria. Patients who fulfill both severity criteria should be transferred to advanced medical units. The revised criteria are extremely useful to detect SAP at an early stage of AP.
