重症急性胰腺炎治疗过程中面临的一个主要难题是在疾病的变化过程中预测其严重程度和潜在并发症。常见的评分标准包括Ranson、APACHEⅡ和序贯器官衰竭评分（SOFA）等。单一的预测指标除白细胞、血氧分压、血糖、血钙外，更有价值的有降钙素原、腹腔内压、Balthazar CT评分等。重症急性胰腺炎两个最重要标志是器官衰竭和胰腺坏死，预后评价应同时考虑器官衰竭和胰腺坏死因素，将形态学和生理学指标相结合，以提高预测的准确性。

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.
