Q

Functional Gastrointestinal disorders (FGID)

very rare in very severe cases of pancreatitis

bruising around the umbilicus

33
Q

bruising around the flanks

34
Q

What is the dx criteria of acute pancreatitis?

A

2 of the 3:

  • abdominal pain consistent with the disease
  • serum amylase and/or lipase greater than 3 times the upper limit of normal
  • abnormal imaging
35
Q

Ranson’s criteria

A

determining the predictive score for a bad outcome with acute pancreatitis

if the pt has 3 or more then they should be admitted and monitored closely in the ICU
vs if they have 1 or 2 criteria they should be fine on the med surg floor

document!

36
Q

When do you drain the pseudocyst?

A

only the pt is have sxs

IV fluids
bowel rest
pain management
DO NOT follow amylase, lipase –only helpful in dx, not following the course of the dz

Q

What is the treatment of acute pancreatitis if the underlying cause if gallstones?

A

cholecystectomy after recovery from pancreatitis

40
Q

During recovery from acute pancreatitis, when should you start feeding them?

we WANT the pt to eat PO

EtOH

43
Q

Why are amylase and lipase not elevated in chronic pancreatitis when they are elevated in acute pancreatitis?

A

because the pancreas tissue has been replaced by scar tissue and is unable to produce large amounts of these enzymes anymore

44
Q

What are common presentations of chronic pancreatitis?

A

abdominal pain
steatorrhea
diabetes mellitus
weight loss

calcifications of abdominal x-ray is dx

45
Q

pain management
stop EtOH
DM treatment

A

Reserved for pts:

  • in whom the dx is unclear (typical pain with normal enzymes)
  • who fail to improve clinically within the first 48-72 hours after hospital admission
