Evaluation of prognostic score based on the Japanese criteria for the severity of acute pancreatitis. Part I. Retrospective study

Abstract

We used the Japanese Ministry of Health and Welfare criteria for acute pancreatitis to obtain a “prognosis score” for disease severity in 63 individuals with severe pancreatitis and we assessed the usefulness of these scores. To convert the Japanese criteria into a score, we excluded the CT grade classification, assigned a value of 1 point to the prognostic factors designated (1), and a value of 0.5 points to the prognostic factors designated (2), and added the number of points to obtain the “prognosis score”. The results showed a clear difference in prognosis between patients who had scores of 1.5 or less and those whose scores were 2.0 or more. These prognosis scores were useful both in rating the efficacy of treatment and in selecting the method of treatment in the early stage. To confirm the value of these scores, it will be necessary to accumulate more cases prospectively and to conduct additional assessments.
