clin med last two lectures Flashcards
Endocrine pancreas (DIABETES)
Islet of langerhan
insulin and glucagon
Exocrine pancreas
Acinar cells- amylase, lipase, protease
Pancreatic juice- electrolytes, bicarb, enzymes, neutralize acid
Acute pancreatitis
Alc induced >Males
Gallstone induced >Females
Pathophys of Pancreatitis
High TRYPSIN levels, pancreas destroys itself
Subtypes of pancreatitis
Necrosis or nah
Two most common causes of Pancreatitis
Gallstones
Alcohol (chronic use)
Abdominal pain with pancreatitis
Acute, post meal
Epigastric –> radiating into back
Constant, steady, boring
Better w leaning forward
PE of Pancreatitis
Tachy, hypo, fever
Sometimes jaundice, pallor, sweating
Epigastric pain
Guarding
Dec bowel sounds
Scleral icterus, be thinking of
Choledocholithiasis or Edema of pancreatic head
Parotid swelling can be sign of
Mumps
Severe necrotizing pancreatitis
Cullen sign- bruising around belly button
Grey turner- bruising to flanks
Panniculitis- red tiny nodules
Labs of Pancreatitis
Elevated:
Bilirubin, Triglycerides, Pancreatic enzymes, LIPASE (more spec to pancreas)
CRP >150= severe pancreatitis
Genetic testing panc
Strong fam hx of pancreatitis
<35 YO onset
If Clinical presentation and Labs are suggestive of Pancreatitis, do we want a CT?
NOT RECOMMENDED
most cases are uncomplicated
IV contrast may worsen panc
Suspect pancreatitis, what imaging do I order?
US –> EUS –> MRCP
Do not do ERCP unless
EUS or MRCP are abnormal
Diagnostic criteria for Pancreatitis,
Requires TWO of the following
Clinical (acute, persistent, severe, boring, epigastric pain radiating to back)
Elevated Lipase or Amylase
Imaging
Get a CT if >72 hours of onset sx AND
Persistent or recurrent abd pain
Inc in panc enzymes after initial decrease
New or worse organ dysfx
Sepsis (fever and increased WBC)
Tx for Pancreatitis
Admit SUPPORTIVE Meds (pain, abx, n/v) Aggressive hydration Monitor for worsening
Complications of pancreatitis
Local (fluid, cyst, necrosis)
Systemic inflammatory response syndrome (SIRS)
Organ failure
Pancreatic pseudocyst
Localized collection of fluid (enzymes, blood, and pancreatic tissue)
Palpable mass mid epigastric
may spont resolve or get bigger
Complicated if: rupture, hemorrhage, infection
Tx of Pancreatic pesudocyst
Surgery vs drainage if symptomatic or infected
Most cases of Pancreatitis are
Mild acute
Better in 3-5 days
- no organ failure
- no local or systemic complications
SIRS
Present on admission
Persists >48 hours
Death related to pancretitis
First 2 weeks: SIRS/organ failure
After 2 weeks: Sepsis
Some causes of pancreatitis you can treat to prevent another case
Remove gallstone
Stop drinking
Lower triglycerides w diet / meds
Discontinue offending med
Chronic pancreatitis
Progressive inflammatory changes
Long term structural damage of pancreas
Is Mortality lower with chronic or acute pancreatitis?
Chronic
Sx of Chronic pancreatitis
STEATORRHEA
DM
weight loss
Brittle DM
alpha and beta cells of pancreas affected d/t chronic pancreatitis
hard to control
typically insulin DEPENDENT
Classic TRIAD of Chronic Pancreatitis
DM
Steatorrhea
Calcifications
Most labs with CHRONIC Pancreatitis are more mild, maybe even normal… so we test
Fecal fat
72 hr: Gold standard
Test of choice for Steatorrhea
Fecal Elastase
Calcifications on X Ray
Calcifications, ductal dilation, and pseudocyst on CT
Chronic Pancreatitis
ERCP (diagnostic and therapeutic) of Chronic Pancreatitis shows what?
“chain of lakes” gold standard
Tx of Chronic Pancreatitis
Behavior Pain relief Lithotripsy Endoscopic dilation or stenting Decompression/drainage
Acute, severe, epigastric pain radiating to back
better w leaning forward
Pancreatitis
Diagnosis of Pancreatitis (at least 2)
Clinical
Labs (lipase/amylase)
Imaging
Triad: DM, steatorrhea, calcifications
“chain of lakes” on ERCP
Chronic Pancreatitis
