Study Notes
General Pathology: Diseases of the Gallbladder and Biliary Ducts
- The presentation covers diseases of the gallbladder and biliary ducts.
- Learning objectives include:
- Clinical presentation of diseases in the bile ducts and pancreas.
- Pathophysiology of cholelithiasis.
- Pathophysiology of cholecystitis.
- Pathophysiology of cholangitis.
- Pathophysiology of pancreatitis.
- Pathophysiology of bile duct tumors.
- Pathophysiology of choledochal cysts.
Gallbladder Lithiasis (Gallstones)
- Composition: Primarily >70% cholesterol and calcium, ~20% bile salts, <10% cholesterol.
- Cause: Precipitation due to high cholesterol and lipid concentration in bile, hemolysis (pigmentary), and gallbladder motility issues.
Complications of Gallbladder Diseases
- Biliary colic
- Chronic cholecystitis
- Acute cholecystitis (with Murphy's sign)
- Bile duct obstruction (Choledocolithiasis)
- Mirizzi's syndrome
- Cholangitis (Charcot's triad)
- Pancreatitis
- Gallstone ileus
- Bouveret's syndrome
Diagnosis
- Clinical manifestations
- Ultrasound
- CT scan
- CholangioMR
- ERCP
- EUS
Acute Pancreatitis
- Causes: Cholelithiasis and alcohol abuse.
- Mechanism: Intracellular trypsin activation leads to necrosis and inflammation. Trypsin inhibitors may play a role.
- Severity scores: Ramson, APACHE I and II, Glasgow, and Blathazar scores.
- Complications: Pseudocysts, abscesses, ascites, hemorrhage, perforation, SIRS, and Multiple Organ Failure (MOF).
Chronic Pancreatitis
- Causes: Alcohol, autoimmune diseases, recurrent, tumors, and cystic fibrosis.
- Complications: Exocrine insufficiency, malabsorption, endocrine insufficiency, diabetes, obstructive jaundice, bowel obstruction, portal vein thrombosis, peptic ulcer, and pain (PAIN).
Tumors of the Bile Ducts
- Gallbladder Carcinoma: Gallstones can cause "porcelain gallbladder".
- Cholangiocarcinoma: Intrahepatic and extrahepatic types.
- Periampullary Tumors: Pancreatic, bile duct, duodenum, ampulla of Vater.
- Pancreatic Cancer
- Intraductal Papillary Mucinous Neoplasm (IPMN)
Cysts of the Bile Ducts
- Todani classification (likely a cyst classification system)
