Hepatobiliary Disease Lecture Powerpoint Flashcards
Pancreatic malignancy usually begins where?
The head of the pancreas - narrows the common bile duct causing painless jaundice
Bile is made ____, and the gallbladder functions to ____ it for storage
constantly, store it
Bile acid metabolic function
Coats products of lipid breakdown to form micelles to help with fat absorption thru this intestinal epithelium
Conjugated bilirubin is not reabsorbed. It enters the colon and is converted to….
….urobilinogen by bacteria, from there some is reabsorbed and secreted into urine (yellow color), most exit colon via conversion to urobilin and sterobilin (brown color)
Congenital abnormalities of the gallbladder
- gallbladder agenesis
- cholecystohepatic duct (gallbladder connects to an intrahepatic duct resulting in potential bile leak if cholecystectomy if not identified and clipped)
Cholelithiasis
Common condition increasing prevalence with age composed of 4 stages
- lithogenic stage (conditions favorable for stone formation)
- asymptomatic gallstone (stones formed, may rest for years)
- symptomatic gallstones (biliary colic)
- complicated cholelithiasis
Most common type of cholelithiasis
Cholesterol stones
Risk factors for cholesterol stones (4)
- female
- age
- obesity
- estrogens
Clinical presentation of cholelithiasis
Often asymptomatic for decades and don’t require treatment, eventually begin to demonstrate biliary colic (patternless epigastric pain usually 30-90 min right upper quadrant random times) alongside n/v, diaphoresis, but no fever, jaundice, or peritoneal signs
Studies for cholelithiasis (5)
- CBC
- LFT
- amylase and lipase
- ultrasound (will pick up solid stones, test of choice***)
- CT if stone is in common bile duct
Porcelain gallbladder
Findings of calcification of the gall bladder wall that is cancer until proven otherwise
Cholelithiasis treatment options (2)
- cholecystectomy upon emergent symptoms, sometimes prophylactically in large stones, first line
- extracorporal shockwave lithotripsy
Acute cholecystitis
Complication of cholelithiasis in long term, inflammation of the GB, in 20% of pts with biliary colic, have colicky pain that becomes constant and may radiate as well as associated N/V and FEVER*** as well as positive murphy’s sign
Risk factors for cholecystitis
- rapid weight loss
- increasing age
- medications (including hormone therapy)
Acute cholecystitis diagnostic studies (4)
- CBC
- pregnancy test to rule out
- ultrasound (very sensitive and specific)
- CT as backup
