Chronic Pancreatitis Flashcards
What is chronic pancreatitis?
= persistent inflammation of the pancreas that results in permanent structural damage with fibrosis and ductal strictures followed by decline in endo and exocrine function
Aetiology of chronic pancreatitis?
50% alcohol (unknown mechanism)
20% idiopathic
Other causes: cystic fibrosis, trauma, hereditary, chronic obstruction by stone, tumour
Pathophysiology of chronic pancreatitis
Same hypothesis as acute pancreatitis. An initiating factor causes protein plugs that lead to obstruction in the ductules leading to chronic inflammation and then fibrosis and strictures
Compare the intial and later signs and symptoms of chronic pancreatitis
Initially patients present with epigastric abdominal pain that can radiate through to the back (like in acute pancreatitis).
However as the acinar cells are progressively destroyed, less enzymes are produced and the pain disappears.
When lipase and protease secretions are
How do we Dx chronic pancreatitis?
- Suspicion on clinical findings
- Bloods: not useful as serum amylase and lipase can be normal late in the disease as exocrine function declines
- AXR: can reveal pancreatic calcification
- CT scan: should be done to rule out pancreatic cancer, also shows the size and texture of pancreas
- Endoscopic retrograde cholangiopancretography (ERCP)
- Pancreatic exocrine function tests
How do we manage chronic pancreatitis?
Management: Similar to acute pancreatitis • IV fluid resuscitation • Fasting • Parenteral analgesics • Acid blockers Addition of: oral pancreatic enzyme supplements and/or insulin as needed
