Acute Pancreatitis Flashcards
(28 cards)
Define acute pancreatitis.
What are causes of acute pancreatitis?
top causes- gallstones, excess alcohol consumption, trauma (ERCP), hypercalcemia, steroids.
Describe the pathophysiology of acute pancreatitis and its sequelae.
premature exaggerated activation of enzymes due to bile –>
(A) increased amylase –> lipase –>
1. lipase –> fat digestion –> fat necrosis –> increased fatty acids –> bind to calcium –> hypocalcemia
2. peripancreatic digestion –> invasion –> abscess –> spiking fever –> sepsis
3. vessel digestion –> intraparenchymal or retroperitoneal haemorrhage –> cullen’s or grey turner’s sign
(B) Failure of islets of langerhan –> decreased insulin –> severe hyperglycemia
(C) systemic inflammatory response –> increased global vascular permeability –> fluid shift in the 3rd space (1st space - intracellular, 2nd - extracellular, 3rd - intra and extra peritoneal or anywhere else)

2) when should this score be carried out?
3) state the interpretation of its results.
for risk stratification
