Abstract    One of the major issues during the management of severe acute pancreatitis is predicting the extent of severity and potential complication. The common scoring systems are Ranson, APACHEⅡ and SOFA. There are multiple single factors are investigated to assess the severity of acute pancreatitis. Besides routine factors as white blood cell, intra-arterial oxygen pressure, blood glucose and calcium, more valuable factors include procalcitonin, intra-abdominal pressure and Balthazar CT scoring system. Two important symbols of severe acute pancreatitis are organ failure (especially multiple organ failure) and pancreatic necrosis. Comprehensive prognosis detecting system should integrate morphological and physiological change of pancreatitis to improve the reliability of prediction.
