Acute Pancreatitis — Diagnosis & Early Management

Key Points

• Stabilize ABCs; begin targeted evaluation without delaying life-saving therapy.
• Use system-specific risk tools to guide testing and disposition.
• Order high-yield tests first; escalate imaging when indicated.
• Start evidence-based initial therapy and reassess frequently.

Algorithm

1. Primary survey and vitals; IV access and monitors.
2. Focused history/physical; identify red flags and likely etiologies.
3. Order system-appropriate labs and imaging (see Investigations).
4. Initiate guideline-based empiric therapy (see Pharmacology).
5. Reassess response; arrange consultation and definitive management.

Clinical Synopsis & Reasoning

Acute pancreatitis is diagnosed by two of three: characteristic epigastric pain, lipase ≥3× normal, and imaging findings. Establish etiology—gallstones, alcohol, hypertriglyceridemia, medications—and assess severity using clinical scores and organ failure. Look for complications (necrosis, fluid collections) and cholangitis requiring urgent intervention.

Treatment Strategy & Disposition

Early aggressive, goal‑directed fluid resuscitation with balanced crystalloids, effective analgesia, and early enteral nutrition are cornerstone therapies. Avoid prophylactic antibiotics; treat infected necrosis when proven. Perform ERCP urgently for gallstone pancreatitis with cholangitis; schedule cholecystectomy during index admission for mild biliary disease. ICU for persistent organ failure; otherwise ward care with frequent reassessment.

Epidemiology / Risk Factors

• NSAIDs/alcohol; biliary disease

Investigations

BISAP (Abbrev.)

Pharmacology

Prognosis / Complications

• Varies by etiology and bleeding severity; rebleeding/perforation

Patient Education / Counseling

• Explain red flags and when to seek emergent care.
• Reinforce medication adherence and follow-up plan.

Notes

Cholecystectomy during index admission for mild gallstone pancreatitis. Consider nasojejunal feeds if gastric outlet issues. Avoid hemoconcentration from inadequate fluids.
