IN THE 10-year period 1941-1950 inclusive, there were 164 cases of admission for acute pancreatitis to the Cincinnati General Hospital. In each case the diagnosis was based on at least one of the following criteria: (1) a consistent clinical history in conjunction with increased serum amylase; (2) surgical observation, and (3) postmortem examination. In each case acute pancreatitis was the major factor in the illness.
