- Microbiological
- Viral: Mumps, Rubella, Varicella, Viral hepatitis, CMV/EBV/HIV, Coxsackievirus/Echovirus/Adenovirus
- Bacterial: Mycoplasma, Campylobacter, Mycobacterium tuberculosis, Mycobacterium avium intracellular, Legionella, Leptospirosis
- Parasitic: Ascariasis, Clonorchiasis, Echinococcus
- Autoimmune: SLE, Polyarteritis nodosa, Crohn disease
- Surgery: ERCP
- Hyperlipidemia
- Hypercalcemia
- Hypothermia
- Emboli/Ischemia
- Drugs
- Steroids
- Azathioprine
- Furosemide
- Mercaptopurine
- Estrogen
- Methyldopa
- H2 blockers
- Valproic acid
- Antibiotics: ampicillin, penicillin, ceftriaxone, isoniazid, macrolides, metronidazole, nitrofurantoin, rifampin, sulfonamides, tetracyclines
- Antivirals: didanosine, interferon/ribavirin, nelfinavir, ritonavir
- Antifungals: 5-fluorouracil, pentamidine, stibogluconate
- Acetaminophen
- Salicylates
- Methanol
- Organophosphates
Clinical Manifestations
- Acute abdominal pain, usually epigastric, sometimes radiating to the back
- Nausea and vomiting
- Fever
- Dyspnea
- Can lead to both endocrine and exocrine dysfunction, including diabetes mellitus and malabsorption
Prognosis
Ranson's Criteria
- On presentation
- Sugar > 10
- WBC > 16k
- Elderly > 55 years
- LDH > 350
- AST > 250
- After 48h
- Hct drop >10% from admission
- BUN increase >5 mg/dL (>1.79 mmol/L) from admission
- Ca <8 mg/dL (<2 mmol/L) within 48 hours
- Arterial pO2 <60 mmHg within 48 hours
- Base deficit (24 - HCO3) >4 mg/dL within 48 hours
- Fluid needs > 6L within 48 hours
BISAP
- BUN > 8.9
- Impaired LOC
- SIRS
- Age > 60
- Pleural effusion
Differential Diagnosis
- Other causes of acute abdominal pain, including peptic ulcer disease, gallstones, cholangitis, cholecystitis, gastrointestinal perforation, intestinal obstruction, mesenteric ischemia, and hepatitis
Diagnosis
- Made based on the presence of two of the following three criteria:
- Compatible history
- Elevated lipase or amylase
- Characteristic findings on imaging
Management
Pancreatic Necrosis
- Two forms
- Acute necrotizing pancreatitis, which is present at the start, and is usually phlegmonous
- Walled-off necrosis, which develops over the course of illness, and is usually an organized collection
- Both are sterile and both can become infected
- No antibiotics warranted in acute necrotizing pancreatitis
- Infection usually develops after about 10 days
- If necrosectomy is indicated, it should be delayed by at least 4 weeks
Splenic Vein Thrombosis
- Monitor
