Q

Complications of pancreatic pseudocyst

A
infected pseudocyst (see fever)
pseudocyst can swell and result in gastric outlet or biliary obstruction, vascular occlusion)
can have fistula formation to adjacent viscera

Q

Lipase level trend in pancreatitis

A

increases 4-8 hrs after pancreatitis
peaks at 24 hrs
returns to normal in 8-14 days

Q

Follow lipase levels??

A

no not in acute pancreatitis. Persistent levels can show pancreatic duct blockage or pseudocyst in sympotmatic patients

Q

Treatment of pancreatic pseudocyst

A

resolve spontaneously and asymptomatic cysts do not need intervention

regardless of size.

Only treat if they are causing significant symptoms

Q

First line therapy to treat chronic pancreatitis?

A

stop ETOH and smoking, increase fluid intake, eat small meals with low fat intake.

Need pancreatic enzyme replacement with exocrine insufficiency and helps with pain even if there’s no exocrine insufficiency (fat soluble vitamin deficiency or steatorrhea.)

Q

what are you supplementing in chronic pancreatitis?

A

pancreatic enzyme replacement - by supplying it as a supplement, you suppression of cholecystokinin CCK release by pancreas so it’s not as streased out.

15
Q

How do you treat abdominal pain in patients with chronic pancreatitis

A

non opioid pain medication as a rule but sometimes will need intermittent opioid medications. but need to rule out pseudocyst formation or PUD prior to starting opiate therapy

TCA can help with pain and are preferred over long term opioids

16
Q

If long term opioids are needed to treat pain related to chronic pancreatitis, which ones are preferred?

A

MS contin or morphine sulfate or fentanyl due to long duration of action. Only 30% patients responded to placebo in one study so there’s often comorbid psychiatric illness

17
Q

management of triglyceride induced pancreatitis

A

IVF and pain control
glucose>500 consider insulin infusion
glucose<500 or severe pancreatitis (lactic acidosis and hypocalcemia) consider aphresis (therapeutic plasma exchange)

18
Q

At what range can TG cause pancreatitis?

A

<500 TG minimal risk
500-999 mild risk
1000-1999 moderate risk
>2000 high risk

other risk factors include pregnancy, ETOH, obesity and uncontrolled DM2

19
Q

management of mild gallstone pancreatitis

A

supportive care (analgesics, IVF’s)

20
Q

management of moderate gallstone pancreatitis (no common bile duct obstruction)

A

supportive care

consider endoscopic ultrasound/ MRCP/ERCP if no improvement in 72 hrs

21
Q

management of severe gallstone pancreatitis (with common bile duct obstruction or cholangitis)

A

ERCP within 24 hrs of admission

22
Q

severe gallstone pancreatitis symptoms

A

see obstruction, dilated CBD, signs of acute cholangitis

  • need urgent (<24hrs) ERCP with sphincterotomy to decrease severity
23
Q

acute cholangitis with gallstone pancreatitis management

A

analgesics for pancreatitis, IVFs and broad spectrum abx

needs ERCP with schinterotomy (in 24 hrs) to remove obstructed stone

24
Q

pts who have gallstone pancreatitis should eventually have:

A

cholecystectomy to reduce risk of recurrence

during same hospitalization.

25
Q

if you suspect infected necrotizing pancreatitis what do you do?

A

Either give empiric antibiotics (carbapenem or floroquinolone + metronidazole)

or get CT guided FNA and if sterile necrosis give supportive care and if infective necrosis give tailored antibiotics

ultimately if doesn’t improve, needs surgical debridement. (called necrosectomy)

26
Q

how often does infected necrosis of pancreas occur in necrotizing pancreatitis?

A

in 1/3 of pts who have severe necrotizing pancreatitis.

They do not improve or deteriorate clinically after a week of hospitalization for pancreatitis

27
Q

how to treat infected necrotizing pancreatitis

A

tx with abx
carbapenem or floroquinolone + metronidazole

or get CT guided aspiration with Gram stain and culture

28
Q

non pancreatic causes of elevated lipase:

A

of non pancreatic elevations for lipase are renal insufficiency, DKA, and SBO or ileus.

can be mildly elevated.

29
Q

chronic pancreatitis complication

A

can have splenic vein thrombosis from chronic pancreatic inflammation

30
Q

when to get ERCP for suspected gallstone pancreatitis

A

only do ERCP if there’s

  • choledolithiasis on imaging studies
  • persistently elevated liver chemistries
31
Q

four types of pancreatic fluid collections related to acute pancreatitis

A
  1. acute peri-pancreatic fluid collections - seen within first 4 weeks and no signs of necrosis. result from rupture of main or side branch ducts as a result of inflammation. these resolve spontaneously.
  2. pancreatic pseudocysts- acute peri-pancreatic fluid collections that persist >4 weeks and develop into well defined walls and contain no solid debris (necrosis)
  3. acute necrotic collections - areas of necrosis in the pancreatic parenchyma and or peripancreatic tissues in the first 4 weeks of acute pancreatitis
  4. walled off necrosis - occurs after 4 weeks, when body liquifies the necrosis contains it within a well defined wall.
32
Q

initial management of acute pancreatitis

A

IVF resuscitation with LR (decrease risk for SIRS) at 250-500 ml/hr and most beneficial in 12-24 hrs

33
Q

treatment of walled off necrosis from pancreatitis

A

can’t be amenable to percutaneous or endoscopic drainage due to solid necortic debris within cavity and may ned endoscopic, radiological or sugrical debridement.

34
Q

mild pancreatitis is defined as

A

no organ failure or local systemic complications

35
Q

moderate pancreatitis

A

local or systemic complications such as necrosis or transient organ failure (<48 hrs)

36
Q

severe acute pancreatitis is

A

SIRS, persistent organ failure (kidney or respiratory) >48 hrs and one or more local complications

mortality rate is as high as 50%

most often it’s respiratory failure and cardiac collapse in <48 hrs.
