    Study Notes

    Acute Pancreatitis Overview

    • Acute pancreatitis is acute inflammation of the pancreas, causing liquefactive necrosis and hemorrhage of pancreatic tissue.
    • Classic symptoms include epigastric pain radiating to the back, nausea, and vomiting.
    • Differentiating acute pancreatitis from other GI disorders is challenging; pancreatic enzymes are often checked.
    • Common triggers include gallstones and alcohol consumption.
    • Physical exam findings are often nonspecific but may include mild abdominal tenderness.

    Key Physical Exam Findings

    • Cullen's Sign: Hemorrhage under the skin near the umbilicus.
    • Grey Turner's Sign: Hemorrhage under the skin in the flank region.

    Pathophysiology

    • Blocked flow of pancreatic enzymes while synthesis continues leads to trypsin activation.
    • Trypsin activates other enzymes (e.g., phospholipase, chymotrypsin, elastase), causing auto-digestion of the pancreas.
    • Trypsin is secreted as trypsinogen and activated by enterokinase in the small intestine; activated trypsin can also activate more trypsin.

    Diagnostic Approach

    • Diagnosing acute pancreatitis involves checking serum pancreatic enzymes (amylase and lipase).
    • Lipase is more specific for pancreatic damage; high levels are significant in severe cases.
    • Liver function tests may be abnormal, particularly if gallstones are causing the pancreatitis.
    • Elevated white blood cell count is also sometimes observed.
    • Imaging (e.g., ultrasound, CT scan) may show gallstones, edema, necrosis, or bile duct dilation.

    Diagnostic Criteria

    • Epigastric pain
    • Increased serum amylase/lipase (greater than three times the upper limit of normal)
    • Abnormal pancreatic imaging (CT/MRI)
    • Diagnosis requires at least two of the three criteria.

    Etiology

    • Gallstones: Gallstones obstructing the common bile duct block pancreatic enzyme flow to the duodenum.
    • Alcohol Consumption: Unknown mechanism, frequently implicated in heavy drinkers.

    Other Causes

    • Idiopathic: No identifiable cause.
    • Trauma: Blunt or penetrating trauma to the pancreas can trigger acute pancreatitis.
    • Infection: Rarely, viral (mumps), bacterial, or parasitic infections can be a cause.
    • Drugs: Certain drugs (GLP-1 agonists, sulfa drugs, 6-mercaptopurine) are associated with acute pancreatitis.
    • Toxins: Arachnid and reptile venoms, such as brown recluse spider, scorpions, and Gila monster, trigger acute pancreatitis.
    • Autoimmune pancreatitis: A rare condition involving IgG4 plasma cells; responds to steroids.
    • Hypercalcemia: Calcium deposits in pancreatic ducts activate enzymes; leads to auto-digestion.
    • Hypertriglyceridemia: Serum triglyceride levels exceeding 1000 mg/dL can lead to acute pancreatitis. Chylomicrons obstruct blood vessels and release free fatty acids.
    • ERCP (Endoscopic Retrograde Cholangiopancreatography) Complications: Injury to pancreatic duct can trigger post-ERCP pancreatitis.
    • Duodenal Ulcers: Rupture can lead to acute pancreatitis.

    Complications

    • Disseminated Intravascular Coagulation (DIC): Widespread clotting depletes coagulation factors, leading to bleeding and microangiopathic hemolytic anemia.
    • Acute Respiratory Distress Syndrome (ARDS): Vascular damage results in fluid leakage into the lungs, leading to respiratory failure.
    • Pancreatic Pseudocyst: Encapsulated collection of fluid and edema, often asymptomatic but can rupture. Locations include lesser sac of abdomen.
    • Pancreatic Abscess: Infected pseudocysts; present with fever and clinical deterioration.
    • Fat Necrosis: Release of free fatty acids, binding calcium; leads to low serum calcium levels.
    • Multi-organ Failure: Severe acute pancreatitis can lead to systemic complications, including DIC, ARDS, infection, and shock; often requiring intensive care unit treatment.

    Treatment

    • NPO (Nil per os): Resting the pancreas.
    • IV Fluids: Maintaining hydration and blood pressure.
    • Pain Control: Managing epigastric pain.

    Monitoring Criteria(e.g., Ranson's Criteria, APACHE II)

    • Predict features at admission or within 48 hours that indicate severe disease potential.
