acute pancreatitis Flashcards
Acute pancreatitis - MCC
90% caused by alcoholism + cholelithiasis
Acute pancreatitis - etiology
I GET SMASHED Idiopathic Gallstones Ethanol Trauma Steroids Mumps Autoimmune Scorpion sting Hypercalcemia/hypertriglyceridemia ERCP Drugs \+ cystic fibrosis, ductal obstruction
Acute pancreatitis - drugs as a cause
drug toxicity: pentamidine, didanosine, azathioprine, estrogen
drug allergy: sulfa such as furosemide, hydrochlorothiazide
Acute pancreatitis - presentation
acute epigastric pain + tenderness + nausea/vomiting
in severe cases there is hypotension + fever
pain - acute pancreatitis vs cholecystitis
pancreatitis - straight through the back like a spear stabbed into the abdomen
cholecystitis - goes around the side to the back
lab - the worst prognosis for acute pancreatitis
low calcium
acute pancreatitis - lipase + amylase prognosis
both elevated, but there is no correlation between the height of these enzyme levels and disease severity
acute pancreatitis - CRP prognosis
CRP has never been shown definite corelation with severity in any disease
acute pancreatitis - best initial test
amylase + lipase
acute pancreatitis - most specific test
CT scan
amylase vs lipase in acute pancreatitis regarding specificity
lipase is more specific
acute pancreatitis - beside Ca, desease severity is also correlates with the
degree of necrosis seen on CT
greater than 30% –> extensive necrosis
acute pancreatitis - extensive necrosis - additional test
needle biopsy is indispensible in determining the presence of infection in those who have extensive necrosis
acute pancreatitis - lab tests
- CBC: leukocytosis, drop in HCT over tume with rehydration
- elevated LDH + AST
- Hypoxia, hypocalcemia
- elevated urinary trypsinogen activation peptide
acute pancreatitis imaging - only the names
- CT or MRI
- MRCP / ERCP
- Plain x ray
- US
acute pancreatitis imaging - CT or MRI
best –> also detects pseydocysts
acute pancreatitis imaging - MRCP / ERCP
MRCP is useful determining the etiology of the disease (diagnostic)
ERCP is for therapy
acute pancreatitis imaging - Plain X-ray
sentinel loop of bowel (air filled piece of small bowel in LUQ
acute pancreatitis imaging - US
very poor accuracy
overlying bowel blocks precise imaging
acute pancreatitis - treatment
- NPO
- IV hydration at very high volume
- analgesia
- PPIs
- +/- antibiotcs
acute pancreatitis - treatment - PPIs?
decrease pancreatic stimulation from acid entering the duodenum
acute pancreatitis - treatment - antibiotics?
if there is more than 30% necrosis on CT or MRI, adding antibiotics such as imipenem or meropenem may decrease mortality by development of infected necrotic pancreatitis
acute pancreatitis - treatment - surgery
infected, necrotic pancreatitis should be resected with surgical debridement to prevent ARDS + Death
Psuedocysts - management
drained with a needle if they are enlarged or painful
acute pancreatitis - ERCP is used to
- remove obstructing stones and dilate strictures
2. place stent
