Acute Pancreatitis Flashcards
what are the common causes of acute pancreatitis?
- alcohol
- gallstones
what is the pathophysiology of acute pancreatitis?
- autodigestion of pancreatic tissue by pancreatic enzymes
- necrosis
what are the features of acute pancreatitis?
- severe epigastric pain that may radiate through to the back
- vomiting
what is seen on examination in acute pancreatitis?
- epigastric tenderness
- ileus
- low-grade fever
- cullen’s sign
- grey-turner’s sign
what is cullen’s sign?
periumbilical discolouration
‘got really drunk with edward cullen and he tried to do a body shot from your belly but he ended up biting you and you got a big bruise’ = periumbilical discolouration in acute pancreatitis
what is grey-turner’s sign?
flank discolouration
‘meridith GREY struts so much she gets bruising on her sides’ = flank discolouration
what investigations should be done in acute pancreatitis?
- serum amylase
- serum lipase
- imaging
what happens to serum amylase in acute pancreatitis?
- >3x the upper limit of normal
- does not correlate with disease severity
what are the causes for raised amylase?
- acute pancreatitis
- pancreatic pseudocyst
- mesenteric infarct
- perforated viscu
- acute cholecystitis
- diabetic ketoacidosis
when is serum lipase particularly useful in acute pancreatitis?
late presentation
longer half-life than amylase so useful in presentations >24 hours delayed
what imaging can be done in acute pancreatitis?
- early ultrasound - assess aetiology
- contrast-enhanced CT
what factors indicate severe pancreatitis?
- age >55 years
- hypocalcaemia
- hyperglycaemia
- hypoxia
- neutrophilia
- elevated LDH and AST
what is the most sensitive blood test for diagnosing acute pancreatitis?
serum lipase
how is severe acute pancreatitis classified?
persistent (>48 hours) organ failure
what is the key aspect of acute pancreatitis management?
fluid resuscitation
aggressive early hydration with crystalloids
