Q

ductules

A

large volume secretions that bring pH close to normal in order to

  • inactivate pepsin
  • increase solubility of fatty and bile acids
  • block mucosal damage
  • optimize pancraetic ad BB enzyeme fx

Q

hereditary ways to get pancreatitis

A

trypsinogen mutations that make it more resistant to deactivation

def of antitrypsin

cystic fibrosis

familial hypertriglyc

17
Q

early complications of pancreatitis

A

massive volume losses secondary to third spacing

SiRS

metabolic abnormalities

peripancreatic necrosis

18
Q

late complications of pancreatiti

A

pseudocysts & abscesses

19
Q

mortality <1 week

A

secondary to sirs or multiorgan failure

20
Q

mortality >1 week

A

pancreatic sepsis or multiorgan failure

21
Q

tx mild pancreatitis

A

iv hydration
rest
remove offending agent

22
Q

tx severe

A

supportive

ERCP for stones, but risk factor fo acute panc

23
Q

typse of mild pancreatitis

A

interstitial or edematous pancreatitis

24
Q

types of severe pancreatitis

A

necrotizing or hemorrhagic pancreatitis

25
pathological hallmark of severe pancreatitis
fatty necrosis
26
saponification
liberated FAs precipitate calcium salts in cytoplasm in svere pancreatitis
27
damage order of pancreatitis
acinar tissue> ducts> islets
28
pseudocyst
walled-off collcetion of fluid or liquified tissue within or adjacent to the pancreas in acute pancreatitis may include adjacent organs no epithe. lining
29
abscess
necrotic tissue or a pseudocyst that becomes infected w/ bacteria or fungi from intestine or blood-->liquefied necrotic tissue
30
etio of chronic pancreatitis
``` alcohol idiopathic hereditary CF autoimmune ductal obstruction tropical ```
31
hereditary panc pt mutation
cationic trypsinogen gene (PRSS1)-- removes a fail safe mech for trypsin inact
32
autoimmune panc on CT
enlarged panc
33
type 1 Aip
igg4
34
pathonmonic for cp
calcified debris in ducts
35
90% of pancreatic cancer
ductal adenocarcinoma
36
RF for panc carcinoma
smoking chronic panc DM
37
3 main types of benign tumors
serous cystadenoma mucinous cysadenoma intraductal papillary-mucinous adenoma
38
neoplasms w/ moderate dysplasia
intraductal papillary-mucinous neoplasm mucinous cystic neoplasm
