pancreatic problems (W4) Flashcards
(30 cards)
acute pancreatitis
ranges from mild edema to severe hemorrhagic necrosis
RF for acute pancreatitis
middle age
african american
etiology of acute pancreatitis
females- billary tract disease
males- ETOH abuse
others like meds
patho of acute pancreatitis
- pancreatic cells injured
- enzymes activated
- auto digestion
- mild-severe pancreatitis
enzymes
trypsin
elastase
phospholipase a
kalikrein
lipase
trysin
edema necrosis hemorrhage
elastase
hemorrhage
phospholipase a
fat necrosis
kalikrein
edema
vascular permeability (leads to ascites)
SM contraction
shock
lipase
fat necrosis
where is pain with acute panreatitis
LUQ
epigastric region
think about: time (acute onset), radiation (to back), tenderness
other manifestations of acute pancreatitis
N/V
abdominal distention
hypo BS
fever
hypotensin
tachycardia
jaundice
amylase/lipase- damage
glucose- not working
WBC- inflammation
cyanosis/green yellow abdomen
echymoses
types of echymoses
flank- grey turners sign
periumbilical- cullens sign
acute pancreatitis complications
pseudocyst
abscess
pulmonary complications
hypotension
tetany from hypocalcemia
increased risk of clotting
lipase
causes fat necrosis, generates FFA, binds to calcium, deposits in retroperitoneum, hypocalcemia
what is a pseudocyst
seen on scan
fluid filled sac- filled with necrotic products and secretions
results in inflammation and scarring
palpable epigastric mass
may perforate- content spills- serious- peritonitis (rigid abdomen)
complications of pancreatic abscess
large fluid filled canvity inside cavity
result of necrosis
may be infected or perforate
clinical presentation similar to pancreatitis plus abdominal mass, fever, increase WBC
how to differentiate between cyst and abscess?
present with a palpable mass
do a scan to differentiate
abscess- drain!
chronic pancreatitis
inflammation for weeks to months
main etiology of chronic pancreatitis
ETOH abuse
what happens during chronic pancreatitis
destruction/necrosis
fibrosis- scar tissue
loss of pancreatic enzyme
loss of insulin
may continue even after ETOH stops- the damage is done
bouts of acute attacks
with progressive signs of dysfunction after attack subsides
problem with chronic pancreatitis
pain
other problems with chronic pancreatitis
DM
malabsorption of fat
weight loss
