Pancreas Flashcards
endocrine issues
DM
this time we discuss exocrine function issues in pancreas
acute pancreatitis
usually mild and resolves spontaneously -> severe acute can lead to hospitalization
cause: obstruction of outflow of pancreatic enzymes usually r/t pancreatic and bile duct obstruction (usually gallstone); also caused by OH, drugs, viral infection
backup of enzymes: autodigestion of pancreatic cells -> inflam (vascular damage, coagulopathy, necrosis, fat necrosis in pancreas)
pancreatic enzymes: trypsin
edema, necrosis, hemorrhage
pancreatic enzymes: elastase
hemorrhage
pancreatic enzymes: phospholipase A
fat necrosis
pancreatic enzymes: kallikrein
edema
vascular permeability -> fluid seeps into space, abd enlarged -> ascites
SM contraction -> pain
shock -> r/t vascular perm
pancreatic enzymes: lipase
fat necrosis
pancreatitis: cm - epigastric pain
in mid abd region
severe
sudden onset, may radiate to back, tenderness and guarding
d/t edema = distention of pancreatic ducts and capsule, and chm irritation and inflammation within perineum, and irritation of biliary tract obstruction or nerves in area
pancreatitis: cm
n/v, abd distention, hypoBS, fever, hypoT + tachy d/t fluid loss, jaundice
lab changes: increase amylase, lipase, and wbc (inflam), glucose and increase or decrease depending on what cells are damaged
cyanosis or green-yellow/brown discoloration of abd
ecchymoses (severe cm) -> r/t hemorrhagic pancreatitis, bleed bc leaking vessels and pools in certain abd areas: flanks (grey turners) and periumbilical (cullens)
pancreatitis: complications
pulm: pain, pleural effusion bc edema and permeability increase
hypoT -> shock
tetany from hypoCa -> lose Ca bc lipase generates free FA that binds Ca
pancreatitis: complications - pseudocyst
fluid filled cavity that surrounds outside of pancreas, can see on CT -> necrotic product and secretions
results in inflam and scaring (longer term issues) of areas near pancreas
cm similar to pancreatitis and palpable epigastric mass
perforate -> peritonitis (sx intervention to prevent)
pancreatitis: complications - abscess
fluid filled cavity inside the pancreas, d/t extensive pancreatic necrosis
can result in further infection and peritonitis (infected or perforate)
cm similar to pancreatitis and abd mass, elevated fever and leukocytosis
chronic pancreatitis
progressive, fibrotic disease of pancreas
OH abuse: toxic metabolites release inflam cytokines and cause destruction of acinar cells and islet of langerhans -> manage glucose and insulin
other rf: genetics, gallstones, obstruction, smoking
pancreatic cysts: walled off areas of pancreatic juice necrotic debris, blood
chronic pancreatitis: cm
attacks of acute pancreatitis with progressive s of dysF after attack subsides
2 major s: abd pain (v hard to treat) and weight loss
can lead to DM r/t loss of langerhans
have issues with nutritional abs -> particularly fats (no enzymes for digestion)
Pancrelipase
Pancreatic enzyme replacement Replace pancreatic enzymes Reduce secretion of pancreatic enzymes
