A

result in permanent damage to structure

Q

according to UCG guidelines, diagnosis of acute pancreatitis includes 2 of the following:

A

abdominal pain: consistent with acute pancreatitis

Q

what bloodwork should be completed on admission of acute pancreatitis

A

CBC
CMP
serum lipase and amylase
lactate
TG
CRP
*best for evolution: rising BUN or rising Hct

17
Q

what is ranson criteria

A

cumbersome, takes 48 hours to compute but good negative predictive valvue for pancreatitis

18
Q

what is BISAP

A

bedside index of severity in acute pancreatitis
simple and calculated during first 24 hours; good positive predictor of severe cases M&M

19
Q

what are the types of acute pancreatitis

A

Intersitital and necrotizing

20
Q

what is intersitial pancreatitis

A

presence of an enlarged pancreas on imaging; peripancreatic stranding and signs of inflammation; more common type, majority of cases are self-limited

21
Q

what is Necrotizing pancreatitis

A

presence of pancreatic and/or peripancreatic necrosis; best seen on contrast-enhanced cross-sectional imaging; occurs in 5-10% of acute pancreatitis and associated with prolonged, more severe disease course

22
Q

what is the more important stage in management of acute pancreatitis

A

first 12-24 hours is the most important
fluid resuscitation
analgesia/meds
nutritional support

23
Q

what is the foundation of management of acute pancreatitis

A

early aggressive fluid resuscitation
-lactated ringer’s solution

24
Q

what are pseudocysts

A

pancreatic and peripancreatic collections of enzyme-rich pancreatic fluid
- fluid or fluid and necrotic material
-most resolve spontaneous

25
what are systemic complicatiosn of acute pancreatitis
single or multiple organ failure and shock risk increased with underlying comorbidities and/or persistent SIRS
26
what is persistent inflammation of the pancrease that leads to permanent structural damage with fibrosis
chronic pancreatitis
27
what are two major risk factors for chronic pancreatitis
drinking alcohol and smoking cigarettes
28
what is the hallmark of pancreatitis
fibrosis caused by inflammation and recurrent pancreatic injury
29
what is the primary manifestation of chronic pancreatitis
abdominal pain and pancreatic insufficiency
30
what is the best imaging for diagnosis of chronic pancreatitis
MRI - confirms diagnosis
31
what are direct pancreatic function tests
monitor actual ssecertion of pancreatic exocrine products (bicarbonate and enzymes) most useful in earlier stage when imaging studies are not diagnostic IV cholecystokinin, IV secretin, duodenal secretion
32
what are indirect pancreatic function tests
measure secondary effects resulting from lack of pancreatic enzymes (e.g. fat malabsorption) less accurate in earlier stages; blood or stool samples serum trypsinogen tests, steatorrhea
33
what is the treatment of chronic pancreatitis
smoking cessation and alcohol abstinence pain control** pancreatic enzyme supplements mgmt: diabetes and other complications
34
what is pancreatic enzyme replacement
25,000 - 50,000IU lipase per meal, half dose with snacks
35
what is the removal of the head of the pancreas due to extensive disease
whipple procedure
36
what is EPI
exocrine pancreatic insufficiency reduction in pancreatic enzyme activity (mainly lipase) in intestinal lumen below threshold for digestive functions
37
what are clinical manifestations of EPI
steatorrhea, flatulence, weight loss, abdominal pain maldigestion and malabsorption
38
what are the primary causes of EPI
adults: chronic pancreatitis children: cystic fibrosis
39
what is the treatment/management of EPI
monitory body weight and BMI screening for nurtritional deficiency referral to dietician adress causes
40
What is the mainstay treatment of EPI
pancreatic enzyme replacement therapy (PERT)
41
what are complications without treatment of EPI
fat malabsorption and malnutrition reduce QOL osteoporosis and osteopenia reduced ability to work increased cardiovascular complicationss
