[The usefulness and limitations of the new Japanese criteria for severity assessment in acute pancreatitis].
New Japanese criteria for severity assessment in acute pancreatitis were introduced in October 2008. The new criteria are simpler than the previous ones, and are also expected to be more useful for the severity assessment. We retrospectively analyzed the clinical factors in our patients to predict prognosis, and evaluated the usefulness and limitations of the new criteria. There were few missing data in the new criteria compared with the previous criteria. The areas under the receiver operating characteristic (ROC) curves for mortality prediction were 0.870 for the new criteria and 0.884 for the previous criteria. However, there were more patients whose disease severity on admission were underestimated using the new criteria and who finally progressed to worse stages including death. This evidence strongly suggests the lower sensitivity of the new criteria in mortality prediction. Repeated assessment of severity after admission will be indispensable in the proper treatment of patients with acute pancreatitis.
