Acute Pancreatitis Severity & Management — free guideline decision tool
This tool stratifies acute pancreatitis by revised Atlanta severity and gives fluid, nutrition, ERCP, and antibiotic direction by biliary and infection status.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Severity (revised Atlanta) | Moderately severe MSAP (transient organ failure < 48 h or local complications) |
|---|---|
| Biliary etiology | Yes |
| Concomitant cholangitis or persistent biliary obstruction | Present |
| Infected pancreatic necrosis or extrapancreatic infection | Present |
→Severity & dispositionModerately severe (MSAP)
- Fluid resuscitation：Immediate crystalloid (lactated Ringer's preferred) [pending update]/h goal-directed resuscitation (urine output > 0.5 mL/kg/h, MAP > 65), reassess repeatedly, beware over-resuscitation causing tissue edema
- Nutrition：Moderately severe/severe: start enteral nutrition within 48–[pending update] (EN over parenteral)
- ERCP/etiology：Biliary with cholangitis/persistent obstruction: emergency ERCP (within 24 h of admission for cholangitis; up to [pending update]for persistent obstruction); cholecystectomy after recovery
| Severity (revised Atlanta) | Mild MAP (no organ failure/complications) |
|---|---|
| Biliary etiology | Yes |
| Concomitant cholangitis or persistent biliary obstruction | Present |
| Infected pancreatic necrosis or extrapancreatic infection | Present |
→Severity & dispositionMild (MAP)
- Fluid resuscitation：Immediate crystalloid (lactated Ringer's preferred) [pending update]/h goal-directed resuscitation (urine output > 0.5 mL/kg/h, MAP > 65), reassess repeatedly, beware over-resuscitation causing tissue edema
- Nutrition：Mild: early oral feeding (low-fat) as tolerated
- ERCP/etiology：Biliary with cholangitis/persistent obstruction: emergency ERCP (within 24 h of admission for cholangitis; up to [pending update]for persistent obstruction); cholecystectomy after recovery
Common questions
What is Acute Pancreatitis Severity & Management?
This tool stratifies acute pancreatitis by revised Atlanta severity and gives fluid, nutrition, ERCP, and antibiotic direction by biliary and infection status.
How is Acute Pancreatitis Severity & Management calculated? What is the core formula?
Severity: mild (no organ failure), moderately severe (transient OF < 48 h or local complications), severe (persistent OF > 48 h). Goal-directed crystalloid; EN within 48–[pending update]; ERCP only for biliary + cholangitis/obstruction; antibiotics only for infection.
When is Acute Pancreatitis Severity & Management used?
Use to set goal-directed resuscitation, early enteral nutrition, and ERCP/antibiotic decisions, escalating severe disease to the ICU.
What are the key clinical points for Acute Pancreatitis Severity & Management?
Prophylactic antibiotics are withheld in the absence of infection, and over-resuscitation is actively avoided because it worsens tissue edema. (original synthesis · not guideline verbatim) Emergency ERCP is reserved for biliary pancreatitis with cholangitis or persistent obstruction. Biliary cases get cholecystectomy after recovery to prevent recurrence.
What are the limits and cautions when using Acute Pancreatitis Severity & Management?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Acute Pancreatitis Severity & Management upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
