Evaluation of severity of acute pancreatitis. According to a report of the cooperative national survey in Japan.

In the cooperative national survey of acute pancreatitis achieved by the Research Committee of Intractable Diseases of the Pancreas supported by the Japanese Ministry of Health and Welfare, 2553 cases of acute pancreatitis, except mild cases, were collected throughout Japan. The severity of disease classification systems that used both the clinical signs of the systemic and local complications and the laboratory values was evaluated. It is probable that the multiple criteria have the potential to provide improved measurement of severity and progress of acute pancreatitis.
