Basics
Description
- Inflammation of pancreas due to activation, interstitial liberation, and digestion of gland by its own enzymes
- Acute pancreatitis:
- Exocrine and endocrine function of gland impaired for weeks to months
- Glandular function will return to normal
- Chronic pancreatitis:
- Exocrine and endocrine functions progressively deteriorate with resultant steatorrhea and malabsorption
- Dysfunction progressive and irreversible
- Pancreatic pseudocyst:
- Cystic collection of fluid with high content of pancreatic enzymes surrounded by a wall of fibrous tissue lacking a true epithelial lining
- Localized in parenchyma of pancreas or adjacent abdominal spaces (lesser peritoneal sac)
- Requires 4–6 wk to form from onset of acute pancreatitis
Etiology
- Gallstones and alcohol abuse most common causes of acute pancreatitis (75–80%)
- Alcohol abuse accounts for 70–80% of chronic pancreatitis
- Acute:
- Biliary tract disease
- Chronic alcoholism
- Obstruction of pancreatic duct
- Ischemia
- Medications
- Infectious
- Postoperative
- Post-ERCP
- Metabolic diseases
- Trauma
- Scorpion venom
- Penetrating peptic ulcer
- Hereditary
- Chronic:
- Chronic alcoholism
- Obstruction pancreatic duct
- Tropical
- Hereditary
- Shwachman disease
- Enzyme deficiency
- Idiopathic
- Hyperlipidemia
- Hypercalcemia
- Pancreatic pseudocyst:
- Complication in 5–16% of acute pancreatitis; 20–40% of chronic pancreatitis
Pediatric Considerations
Causes mainly viral, trauma, medications, anatomic abnormalities
