clin med- third set lectures Flashcards
Cystic duct comes from:
gallbladder
Common hepatic duct comes from:
liver
Common bile duct consists of:
Cystic and Common Hepatic duct joining.
The Common bile duct then empties into duodenum thru sphincter of Oddi
What organ does the Common bile duct pass thru before it empties into duodenum?
Pancreas
Who makes bile?
Liver
then stored and concentrated in the Gallbladder
Function of bile
Digest/absorb fats
Vehicle to excrete: bilirubin, extra cholesterol, and met byproducts
inflammation of the BILE DUCTS
Cholangitis
Inflammation of the Gallbladder
Cholecystitis
Stones in the Gallbladder
Cholelithiasis
Stones in the Common Bile Duct
CholeDOCHOlithiasis
Disruption of bile flow
Cholestasis
The Four F’s of Cholelithiasis (Gallstones)
Risk factors
Female
Fluffy
Forty
Fertile
Also: Pregnant, Estrogen use, Rapid weight loss, Fam hx/genetics, DM
What type of stone is most common?
Cholesterol
other types: Pigment, Black pigment (underlying hemolytic anemia), Brown pigment (bacterial infection)
Do most gallstone pts have sx?
NO
If they do, Biliary colic and possibly leading to Gallstone related complications
Test of choice for Cholelithiasis (gallstones)
US
Do you have to treat Gallstones if you have no sx?
No, UNLESS:
- increased risk of GB CA
- Hemolytic disorder
Uncomplicated Gallstone dz
Biliary colic in the absence of complications
Biliary colic
NO gallbladder inflammation
Gallbladder contracts forcing stone/sludge against GB outlet or duct opening, increased pressure–> pain, pain slowly subsides as gallbladder relaxes
Biliary colic sx
RUG or epigastric pain radiates to R shoulder blade
constant and steady
at least 30 min, often peak at 1 hour
post-prandial
Other sx with Biliary colic
n/v
diaphoresis
unchanged by movement
Nocturnal pain common (awakes pt from sleep)
Biliary colic PE
NO FEVER or tachy
vitals normal
no jaundice
Negative murphys
Basically, everything is normal besides
POSSIBLE RUQ or EPIGASTRIC tenderness
Biliary colic
order labs and US
labs: normal
US: expect Gallstones or Sludge
If pt has Stones and Biliary colic
Cholecystectomy recommended
Functional Gallbladder disorder
gallbladder DYSMOTILITY
Biliary type pain but NO stones, sludge, or dz
Normal labs, Normal imaging
Functional Gallbladder disorder dx
look at Ejection Fraction via HIDA scan
Diagnosis of exclusion
HIDA scan tells Ejection Fraction
CCK given to stimulate gallbladder contraction, if ejection fraction is <35-40%
Considered LOW
Supports dx of Functional gallbladder dz
Rome 4 Criteria required for Functional GB dz
Biliary Pain
Absence of stones or other structural path
Supportive:
Low EF, Normal liver enzymes
Biliary colic type pain must last at least
30 minutes
Tx for Functional gallbladder dz if EF <40
Cholecystectomy
Complicated gallstone dz
Cholecystitis
CholeDOCHOlithiasis
Acute cholangitis
Acute calculous cholecystitis
acute inflammation of gallbladder
usually a COMPLICATION from a STONE
What does Acalculous vs Calculous cholecystitis mean?
Acalculous: no obstruction
Calclous: occurs in the setting of Cystic duct obstruction
Starts with biliary pain that prog worsens
Prolonged >4-6 hours, steady, severe, RUQ or epigastric pain
FEVER
sx of Acute calculous Cholecystitis
can also have n/v, anorexia, radiating to r shoulder, often hx of fatty food eating
PE of Acute calculous cholecystitis
FEVER, tachy Ill appearing Lying still Guarding \+ Murphy's sign
