Study Notes

Chronic Pancreatitis

  • Definition: Chronic pancreatitis is less common than acute pancreatitis, characterized by fibrosis and calcification in the pancreas due to recurrent acute pancreatitis.
  • Causes (adults): Primarily alcohol consumption.
  • Causes (children): Usually cystic fibrosis.
  • Diagnosis: A classic finding on CT scan is calcification in the pancreas (white spots).
  • Symptoms: Chronic abdominal pain, often worse after meals, fluctuating intensity.
  • Impact on Patients: Can result in fear of eating and weight loss; frequent visits to physicians and emergency rooms; often require narcotics for pain management.
  • Enzyme Levels: Serum amylase and lipase levels are typically mildly elevated or normal, not markedly elevated as in acute pancreatitis. This is likely due to pancreas tissue destruction reducing enzyme production.

Complications of Chronic Pancreatitis

  • Splenic Vein Thrombosis: Pancreatic inflammation can lead to splenic vein thrombosis.
    • Mechanism: Obstruction of blood drainage from the spleen.
    • Consequence: Dilated blood vessels (varices) form in the stomach.
    • Presentation: Upper GI bleed, enlarged spleen, presence of gastric varices on endoscopy.
    • Treatment: Splenectomy (removal of the spleen)
  • Pancreatic Insufficiency: Loss of exocrine and endocrine functions due to pancreas damage.
    • Mechanism: Results in decreased enzyme production impacting nutrient absorption.
    • Consequences: Fat malabsorption (steatorrhea), deficiencies in fat-soluble vitamins, diabetes (due to loss of insulin production).

Pancreatic Cancer

  • Type: Adenocarcinoma.
  • Location: More common in the head of the pancreas.
  • Mechanism: Obstructs bile flow into the duodenum, leading to jaundice.
  • Presentation: Vague abdominal pain, weight loss. Key characteristic is painless jaundice due to slow tumor growth.
  • Symptoms: Jaundice (yellowing of skin), dark urine, clay-colored stools, potentially steatorrhea, Courvoisier's sign (enlarged, non-tender gallbladder).
  • Trousseau Syndrome: Migratory superficial thrombophlebitis (inflammation and thrombosis in the superficial veins).
  • Presentation: Redness and induration on the skin which moves from one place to another on the body.
  • Mechanism: Due to a hypercoagulable state in pancreatic cancer.
  • Risk Factors: Age over 50, smoking, diabetes, chronic pancreatitis (more than 20 years). Alcohol is NOT a strong risk factor, unless chronic pancreatitis occurs first.
  • Genetic Factors : BRCA2 mutations, K-RAS gene mutations, SMAD4 gene mutations.
  • Diagnosis: Possible tumor markers (CA-19-9, CEA).
  • Prognosis: Very poor, usually metastatic at presentation; 5-year survival is low (10% if lymph nodes positive, higher at 25% if lymph nodes are negative).
  • Treatment: Chemotherapy, radiation, surgery (Whipple procedure, pancreaticoduodenectomy).
