Description
Serum lipase increases rapidly in patients with acute and recurrent pancreatitis, pancreatic abscess or pseudocyst, pancreatic trauma, pancreatic cancer, common-bile-duct-obstruction, ingestion of drugs that are toxic to the pancreas, most inflammatory conditions in the abdominal cavity, biliary tract disease, abdominal abscesses, and renal failure. Lipase is more specific than total amylase in the diagnosis of acute pancreatitis.
