Educational Pearls:

Alcohol and gallstones are most common causes of pancreatitis
Diagnosis is not simply based on lipase alone - must have at least two the the three criteria:
- Elevated lipase (greater than 3x upper limit of reference range)
- Typical pain (epigastric pain, radiating to back, etc.)
- Radiographic findings suggestive of pancreatitis (CT, MRI, US)
BISAP criteria can help risk stratify mortality in pancreatitis. You get 1 point for each of the following:
- BNP > 25
- Impaired mental status
- SIRS criteria, more than 2
- AGE > 60
- Pleural effusion
BISAP score of 0 has

Editor's note: The severity of pancreatitis does not correlate with serum lipase levels - notice how it is not used in the BISAP criteria, as an example. Even a mild elevation in serum testing can result in severe pancreatitis.
