Q

What is the treatment for asymptomatic gallstones?

A
  • Majority of patients do not require treatment
  • managed expectantly
  • referred for cholecystectomy if symptoms develop

** these patients are surgically treated IF they have increased risk of gallbladder cancer or hemolytic disorders

Q

What is the etiology of biliary colic?

A
  • There is NO inflammation of the GB
  • As the GB contracts, it forces a stone against the GB outlet or cystic duct opening. This increases intra-GB pressure which results in pain. As the GB relaxes, the pain improves

25
Will a patient with acute cholecystitis have a positive Murphys sign?
Yes
26
What will you see on US that supports a diagnosis of acute cholecystitis?
- Presence of gallstones - wall thickening or edema - pericholecystic fluid - positive sonography could murphys sign
27
What HIDA result would support a diagnosis of acute cholecystitis?
Failure to visualized the gallbladder in setting of cystic duct obstruction
28
What are the possible complications of acute cholecystitis and which is the most common?
- Gangrene is the most common - perforation (often after development of gangrene) - cholecystoenteric fistula - gallstone ileus - emphysematous cholecystitis - Mirizzi syndrome
29
What is the Mirizzi syndrome?
A complication of acute cholecystitis, occurs when a gallstone impacted in the distal cystic duct causing extrinsic compression of the CBD, may cause jaundice
30
What is the management of acute cholecystitis?
- Admit, NPO, IV fluids, IV pain control, IV abx | - Cholecystectomy is mainstay of treatment
31
What is acute acalculus cholecystitis?
Acute necroinflammatory disease of the gallbladder in the absence of gallstones
32
What is the pathogenesis of acute acalculus cholecystitis?
- GB stasis and ischemia leading to local inflammatory response in the gallbladder wall - secondary bacterial infection is common
33
What is the clinical presentation of acute acalculous cholecystitis?
-Critically ill patients with sepsis without a clear source, or jaundice
34
Patient presents with biliary type pain. On physical exam, patient appears jaundiced. Upon abdominal palpation, patient has RUQ tenderness and Courvoisier sign. What are you suspicious of?
Choledocolithiasis
35
What is Courvoisier sign?
Palpable gallbladder
36
What will liver function tests show if a patient has choledocholithiasis?
-Elevated ALT and AST in the early course of biliary obstruction. Later, liver tests are elevated in a cholestatic pattern
37
If you are unable to confirm a diagnosis of choledocholithiasis with US, what should you order next?
MRCP is used to confirm dx of CBD stone
38
What is the management of Choledocholithiasis?
- Removal of stone - Identify and treat complications (acute cholangitis, acute pancreatitis) - ERCP (therpeutic and diagnostic) - Cholecystectomy
39
What causes acute cholangitis?
- caused primarily by a bacterial infection in a patient with biliary obstruction (choledocholithiasis, benign biliary stricture, s/p ERCP, malignancy) - bacteria typical ascend from the duodenum
40
What is the clinical manifestation of acute cholangitis?
Fever, abdominal pain, and jaundice | -possible mental status change and hypotension, which are signs of significant morbidity
41
What is Charcots triad?
Fever, abdominal pain and jaundice
42
What is Reynolds Pentad?
Fever, abdominal pain, jaundice, mental status changes, and hypotension
43
What is the management of acute cholangitis?
- admit - monitor for and treat sepsis (empiric abc coverage) - emergent consult with GI and surgery (establishing biliary drainage, typically with ERCP)
44
How can biliary drainage be established in acute cholangitis?
-ERCP with sphincterotomy and stone extraction
45
Which two biliary problems would have leukocytosis?
Acute cholecystitis and acute cholangitis
46
What is primary biliary cholangitis (PBC)?
Autoimmune destruction of the intrahepatic bile ducts which causes cholestasis -may result in cirrhosis and liver failure
47
What is the clinical presentation of PBC?
- ma be asymptomatic - fatigue and pruritis are the most common - RUQ pain, skin hyperpigmentation, hepatomegaly, jaundice
48
What lab tests should you order if you suspect PBC?
- Antimitochondrial antibodies (AMA) is the serologic hallmark of PBC - elevated liver tests in a cholestatic pattern
49
What are the possible complications associated with PBC?
-Cirrhosis, hepatocellular carcinoma, malabsorption, and metabolic bone disease
50
What is the criteria to diagnose PBC?
- No extrahepatic biliary obstruction - No comorbidity affecting the liver - and at least two of the following are present: elevated alk phos, positive AMA, and histological evidence of PBC (liver biopsy)
51
What is primary sclerosis cholangitis (PSC)?
- A sclerosing, inflammatory, obliterative process involving the intrahepatic and/or extrahepatic biliary tree - chronic and progressive disorder of unknown etiology
52
What is PSC commonly associated with?
IBD ( UC more than CD)
53
What are the symptoms of PSC?
Asymptomatic, fatigue, pruritis, jaundice, and hepatomegaly
54
Will PSC have a positive AMA?
No
55
How is PSC diagnosed?
- Elevated liver tests in a cholestatic pattern - cholangiography (MRCP or ERCP showing multifocal strictures and dilation of intrahepatic and/or extrahepatic ducts) - Liver biopsy
56
What are the possible complications of PSC?
- ESRD - vitamin deficiency - metabolic bone disease - Hepatobiliary cancer - colon cancer
57
What is Gilbert syndrome?
- And inherited disorder that results in deficiency in the enzyme for glucuronidation of bilirubin in the liver - results in unconjugated hyperbilirubinemia in the absence of hemolysis
58
What is the clinical presentation of Gilbert syndrome?
- Mild intermittent episodes of jaundice triggered by dehydration, fasting, menstruation, etc - otherwise more are asymptomatic with a normal PE
59
What is the most common cancer arising in the biliary tract?
Gallbladder cancer
60
What are the risk factors for GB cancer?
- Gallstone disease - porcelain GB - GB polyps - PSC - chronic infection - obesity
61
What is cholangiocarcinoma?
Cancer that arise from the epithelial cells of the bile duct
62
What is cholangiocarcinoma commonly associated with?
PSC and choledochal cysts
63
What is the clinical presentation of cholangiocarcinoma?
- Jaundice, pruritis, abdominal pain, weight loss, fever, and rarely a palpable gallbladder - labs may indicate cholestasis
64
Where does ampullary carcinoma occur?
-arise in the vicinity of the ampulla of vater, distal to the bifurcation of the distal CBD and pancreatic duct
65
What condition increases the risk of ampullary carcinoma?
Familial adenomatous polyposis
