Plasma concentrations of bilirubin, alkaline phosphatase (AP), and glutamic oxaloacetic transaminase (GOT) were measured during 122 attacks of acute pancreatitis in 114 patients, on the day of admission to hospital and 2 days after admission. Concentrations in 74 attacks associated with gallstones were compared with concentrations in 31 attacks in which no stones were found. 24 attacks were severe by clinical criteria. On the day of admission plasma GOT concentrations of more than 60 IU/1 were found in 88% of attacks associated with gallstones, but in no attacks without gallstones. Plasma concentrations of more than 25 μmol/l bilirubin and more than 14 King-Armstrong units AP were found in 62% and 66%, respectively, of attacks associated with gallstones, and 5% and 10%, respectively, of attacks without stones. In attacks associated with gallstones plasma concentrations of GOT and bilirubin usually fell over the first 48 h of admission. No correlation was observed between these biochemical values and the severity of the attack. In the absence of a history of excessive alcohol consumption, increases in plasma GOT on the day of admission to hospital suggest that gallstones are responsible for the pancreatitis.
