Pancreatitis Flashcards
What are the two types of pancreatitis?
acute
chronic
What is the most common cause of pancreatitis?
alcohol - 70%
How can alcohol cause pancreatitis?
It causes intracellular accumulation of digestive enzymes and premature release/activation
also increases the permeability of the ductules, so you get those enzymes into the parenchyma
dauses autodigestion of the pancreas
What is the obstructive cause of pancreatitis?
cholelithiasis that lodge int he pancreatic duct or ampulla of vater
leads to backward buildup of enzymes that then leak into the parenchym
There are tons of other causes, but what are two more common?
elevated tiglycerides over 1000
meds
Why does inflammation spread so easily from pancreatitis?
it’s retroperitoneal so there’s not much to stop it
What enzyme starts the autodigestion and what contribute afterwards?
trypsin starts it
Phospholipase A, elastase, lipase and chymotrypsin contrinue it
What will happen pathologically first? THen what’s th eprogression? WHat’s the worst thing that can happen?
parenchymal edema and peripancreatic fat necrosis occurs first
this can progress to necrosis involving the parenchyma = this is the worst = hemorrhagic or necrotixing pancreatitis
What are the symptosm of acute pancreatitis?
mid-epigastric pain = often severe with moderately rapid onset. it’s progressive and constant. can radiate to the back.
some people have nausea and vomiting
What will the patient with acute pancreatitis look like?
will appear very ill - holding abdomen and likely moving around (unable to get comfortable)
WHat will you see on exam in acute pancreatitis?
tender epigastrum
pleural effusion
fever
decreased BP, increased HR and RR
Gray TUrner and Cullen’s sign
WHat is Gray TUrner sign? What is Cullen’s sign?
Gray turner = fank ecchymosis
Cullen = periumbilical ecchymosis
It’s from severe hemorrhagic pancreatitis caused by leaking retroperitoenal blood
What’s the main lab test for looking at acute pancreatitis? What one isn’t all that helpfil?
lipase is best
amylase doesn’t really do much
What are some other lab findings you might see in acute pancreatitis?
high WBC, increased glucose, dehydration, high bilirubein, LDH and AST. Low calcium. low albumin, low O2 (can lead to an ARDS presentation), CRP can be elevated - this is a bad sign
urinary trypsinogen 2 maybe in the future
What criteria are used to predict mortality?
Ranson’s criteria - the higher number increases mortality risk (after 48 hours)
