Overview
Diagnosis
According to the American college of gastroenterology, following are the diagnostic guidelines for acute pancreatitis:[1][2][3][4][4][5]
| Recommendation | Evidence Level | Strength of Recommendation |
|---|---|---|
| The diagnosis of AP is most often established by the presence of two of the three following criteria: (i) abdominal pain consistent with the disease, (ii) serum amylase and/or lipase greater than three times the upper limit of normal, and/or (iii) characteristic findings from abdominal imaging. | Moderate | Strong |
| Contrast-enhanced computed tomographic (CECT) and/or magnetic resonance imaging (MRI) of the pancreas should be reserved for patients in whom the diagnosis is unclear or who fail to improve clinically within the first 48-72h after hospital admission. | Low | Strong |
Ranson Criteria
It was introduced in 1974.[6] It is a clinical prediction rule for predicting the severity of acute pancreatitis.
Usage
Parameters used:
At admission:
- Age in years >55years
- White blood cell count > 16000/mcL
- Blood glucose > 11 mmol/L (>200 mg/dL)
- Serum AST > 250 IU/L
- Serum LDH > 350 IU/L
After 48 hours:
- Haematocrit fall > 10%
- Increase in BUN by 1.8 or more mmol/L (5 or more mg/dL) after IV fluid hydration
- Hypocalcemia (serum calcium < 2.0 mmol/L (<8.0 mg/dL))
- Hypoxemia (PO2 < 60 mmHg)
- Base deficit > 4Meq/L
- Estimated fluid sequestration > 6L
The criteria for point assignment is that a certain breakpoint be met at anytime during that 48 hour period, so that in some situations it can be calculated shortly after admission. It is applicable to both biliary and alcoholic pancreatitis.
For gallstone pancreatitis:
At admission:
- Age in years > 70 years
- White blood cell count > 18000 cells/mm3
- Blood glucose > 12.2 mmol/L (> 220 mg/dL)
- Serum AST > 250 IU/L
- Serum LDH > 400 IU/L
At 48 hours:
- Hematocrit fall > 10%
- Calcium (serum calcium < 2.0 mmol/L (< 8.0 mg/dL)
- Oxygen (hypoxemia PO2 < 60 mmHg)
- BUN increased by 1.8 or more mmol/L (5 or more mg/dL) after IV fluid hydration
- Base deficit (negative base excess) > 5 mEq/L
- Sequestration of fluids > 4 L
Interpretation
- If the score >=3, severe pancreatitis likely.
- If the score < 3, severe pancreatitis is unlikely
Or
- Score 0 to 2 : 2% mortality
- Score 3 to 4 : 15% mortality
- Score 5 to 6 : 40% mortality
- Score 7 to 8 : 100% mortality
