Slide 2: Introduction to Acute Pancreatitis
Acute pancreatitis is a sudden inflammation of the pancreas that can range from mild to life-threatening. It occurs when digestive enzymes become activated inside the pancreas, causing damage to the organ itself.
- Common causes: Gallstones, alcohol use, hypertriglyceridemia, trauma, infections, medications.
- Symptoms: Severe abdominal pain, nausea, vomiting, fever, and in severe cases, shock or organ failure.
Slide 3: Pathophysiology of Acute Pancreatitis
The pancreas produces enzymes that aid in digestion. Normally, these enzymes are inactive until they reach the small intestine. However, in acute pancreatitis:
- Enzymes are prematurely activated within the pancreas.
- This leads to autodigestion, where the pancreas starts breaking down its own tissue.
- Inflammatory mediators are released, leading to systemic complications such as edema, necrosis, and multi-organ dysfunction.
Slide 4: Classification of Acute Pancreatitis
Acute pancreatitis is classified based on severity and etiology:
- Mild Acute Pancreatitis (MAP): No organ failure or local complications.
- Moderate Acute Pancreatitis (SAP): Temporary organ failure or minor complications.
- Severe Acute Pancreatitis (SAP): Persistent organ failure or major complications like pancreatic necrosis.
Etiological classification:
- Gallstone-related
- Alcohol-related
- Idiopathic
- Post-ERCP
- Trauma-related
Slide 5: Clinical Features and Symptoms
Patients typically present with:
- Epigastric pain that radiates to the back.
- Nausea and vomiting, often persistent.
- Fever and tachycardia in more severe cases.
- Abdominal tenderness and guarding may be present.
In severe cases:
- Hypotension
- Respiratory distress
- Altered mental status
Slide 6: Diagnostic Evaluation
Diagnosis is based on clinical findings and laboratory tests:
- Serum amylase and lipase levels: Elevated, especially lipase.
- Imaging studies:
- Abdominal ultrasound for gallstones.
- CT scan for severity assessment and complications.
- MRI/MRCP for detailed evaluation of biliary and pancreatic structures.
Slide 7: Complications of Acute Pancreatitis
Common complications include:
- Pancreatic pseudocyst
- Necrotizing pancreatitis
- Biliary obstruction
- Infection
- Multi-organ failure
- Pleural effusion or respiratory insufficiency
Early recognition and management are critical to prevent progression.
Slide 8: Treatment and Management
General management:
- Fasting and NPO (nothing by mouth)
- IV fluids for hydration
- Pain control with analgesics (avoiding opioids if possible)
- Monitoring for complications
Specific treatments:
- Gallstone removal via ERCP if indicated.
- Antibiotics only in infected necrosis.
- Nutritional support in prolonged cases.
Slide 9: Prevention and Risk Factors
Prevention strategies include:
- Limiting alcohol consumption
- Maintaining a healthy weight
- Managing hypertriglyceridemia
- Prompt treatment of gallstones
Risk factors:
- Alcohol abuse
- Obesity
- Family history
- Certain medications
Slide 10: Prognosis and Follow-Up
Most patients with mild acute pancreatitis recover fully with appropriate care.
However, severe cases may require hospitalization and intensive care.
Follow-up includes:
- Monitoring for recurrence
- Assessing for long-term complications
- Managing underlying conditions
Slide 11: Summary
- Acute pancreatitis is a common and potentially serious condition.
- Early diagnosis and intervention improve outcomes.
- Management depends on the severity and underlying cause.
- Prevention and follow-up play key roles in reducing recurrence and complications.
