🔥 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.
Clinical takeaway
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)

When to use
Use to set goal-directed resuscitation, early enteral nutrition, and ERCP/antibiotic decisions, escalating severe disease to the ICU.
How it works
Severity: mild (no organ failure), moderately severe (transient OF < 48 h or local complications), severe (persistent OF > 48 h). Goal-directed crystalloid; EN within 48–72 h; ERCP only for biliary + cholangitis/obstruction; antibiotics only for infection.
Key points
- 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.

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) | 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) 5–10 mL/kg/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 72 h for persistent obstruction); cholecystectomy after recovery
| Severity (revised Atlanta) | Severe SAP (persistent organ failure > 48 h) |
|---|---|
| Biliary etiology | No |
| Concomitant cholangitis or persistent biliary obstruction | Absent |
| Infected pancreatic necrosis or extrapancreatic infection | Absent |
→Severity & dispositionSevere (SAP)
- Fluid resuscitation：Immediate crystalloid (lactated Ringer's preferred) 5–10 mL/kg/h goal-directed resuscitation (urine output > 0.5 mL/kg/h, MAP > 65), reassess repeatedly, beware over-resuscitation causing tissue edema; SAP warrants ICU, norepinephrine and organ support if needed
- Nutrition：Moderately severe/severe: start enteral nutrition within 48–72 h (EN over parenteral)
- ERCP/etiology：Non-biliary: no ERCP indication; treat the cause (hypertriglyceridemia, hypercalcemia, alcohol, etc.)
