Flashcards

Intraductal Papillary Mucinous Neoplasm (IPMN)

A type of pancreatic cancer characterized by precancerous growths in the pancreatic duct.

Exocrine Pancreatic Insufficiency

A condition where the pancreas produces insufficient digestive enzymes, leading to food malabsorption.

Bile Duct Obstruction

A serious condition where the bile duct becomes narrowed, causing pain, jaundice, and potential liver damage.

Porcelain Gallbladder

A condition where the gallbladder develops a hardened, calcified wall, increasing the risk of cancer.

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)
