gallbladder stotnes part 2 Flashcards
what is choledocholithiasis and presentation
stones in the CBD causing extrahepatic obstruction.
persistent RUQ pain radiating to epigastrium or back after fatty meals.
signs of cholestasis: jaundice, pale stool, dark urine, pruritis. N/V
diagnosis and treatment of choledocholithiasis?
LFTs: high GGT, ALP, total and direct bilirubin (means cholestasis)
to rule out other differentials:
CBC: high WBC in cholecystitis and cholangitis
amylase, lipase: high in biliary pancreatitis
abdominal ultrasound: dilated CBD
MRCP can be done but ERCP is gold standard for diagnosis and tx. if failed: do open surgery.
complication of ERCP: acute pancreatitis
definition and causes of acute (ascending) cholangitis
obstruction of CBD with infection of bile ducts.
causes:
-choledocholithiasis
-malignancy (cholangiocarcinoma/ pancreatic cancer)
-biliary stricture (congenital, infectious, iatrogenic from ERCP/stent)
-extrinsic compression (like mirizzi syndrome)
symptoms of acute cholangitis?
charcot triad: RUQ pain, high fever, jaundice
reynold pentad: charcot triad plus altered mental status and hypotension
con progress to septic shock
diagnosis and tx of acute cholangitis
CBC: high WBC
cholestasis: high direct and total bilirubin, high GGT, ALP
high CRP
initial imaging test: US
obstructed CBD
narrow bile ducts (stricture)
biliary tumor
confirmatory imaging with CT contrast or MRI/MRCP
tx: IV antibiotics and ERCP to relieve obstruction/ tx the underlying cause
