The value of the lipase/amylase ratio for early etiological differentiation of acute pancreatitis was tested in 103 consecutive patients with acute pancreatitis from an ongoing prospective study. On admission, amylase, but not lipase, was significantly lower in alcoholics than in nonalcoholics in general and especially in patients with biliary pancreatitis. ⋯ Finally, there was no correlation between the ratio and the amount of pancreatic changes as judged from computed tomography. We concluded that the ratio does not allow for early routine clinical differentiation between etiologies of pancreatitis and evaluation of the severity of the disease.
