Acute pancreatitis
Background
Etiology
- alcohol
- gallstone
- drugs- azathioprine, cisplatin, lasix, tetracycline, thiazides, sulfa
- hypercalcemia
- hyperlipidemia
- infection
- pregnancy
- scorpion bite
- trauma
- tumor
Diagnosis
- Elevated lipase (more specific and sensitive than amylase)
Treatment
- "Place the pancreas at rest"
- NPO (clears is probably ok for mild/moderate cases)
- IV fluids!
- Electrolyte repletion as needed
- NGT if ileus is present
- Consider antibiotics for established infection/ severe cases
Complications
Local
- Pseudocyst, abscess
Systemic
- Cardiac dysfunction
- Renal failure
- Respiratory failure (due to phospholipase damage to surfactant/ increased cap permeability)
- Shock
- Hypocalcemia (due to sequestration in necrotic fat)
- Hyperglycemia
Prognosis
RANSON CRITERIA
- age >55
- WBC > 16k
- glucose > 200
- LDH > 350
- AST> 250
WITHIN 48 HRS
- hct fall of > 10%
- bun increase > 5
- Ca++ < 8
- PO2 < 60
- base deficit > 4
- fluid seqeustration > 6L
0-2= 1% mortallity, 15% for 3-4, 40% for 5-6, 100% for 7 or more signs
APACHE-II
- Highest sensitivity and specificity in distinguishing mild from severe pancreatitis
- Can be used to estimate risk of hospital death at admission

Disposition
- If mild case + tolerating clears + no e/o gallbladder etiology then consider
d/c home
- All other patients should be admitted
