Study Notes

Acute Pancreatitis

Inflammation of the pancreas caused by activation of the gland's own enzymes, leading to tissue damage.
Incidence: 5-10 per 100,000 people in Western countries.
20% of cases are severe.

Etiologies

Various causes, including gallstones, alcohol abuse, and high triglycerides.

Diagnosis

Symptoms:
- Sudden severe epigastric pain radiating to the back.
- Nausea and vomiting.
- Tachycardia and postural hypotension.
- Normal or slightly elevated fever.
Physical Examination:
- Abdominal distension or generalized tenderness.
- Decreased bowel sounds.
- Mass due to pancreatic phlegmon, abscess, or pseudocyst.
- Grey Turner's sign and Cullen's sign (retroperitoneal bleeding).
Laboratory Tests:
- Elevated enzyme levels (3-fold or more increase in amylase).
- Lipase levels (more specific than amylase, but less sensitive).
- Leukocytosis, hematocrit, and elevated liver enzymes.
- Trypsinogen and elastase levels (reflect pancreatic damage more sensitively and specifically than amylase).
Radiological Examinations:
- Chest X-ray (to rule out complications).
- Abdominal X-ray.
- Computed Tomography (CT) scan (to assess severity).
- Ultrasound (USG).
- Endoscopic Ultrasound (EUS), Endoscopic Retrograde Cholangiopancreatography (ERCP), Magnetic Resonance Cholangiopancreatography (MRCP), and Magnetic Resonance Imaging (MRI).

Management of Acute Pancreatitis

Diagnosis: Based on abdominal pain, elevated enzyme levels, and imaging studies (CT if necessary).
Pain Management:
- Narcotics (except morphine).
- Non-steroidal anti-inflammatory drugs (NSAIDs) or opioids.
Fluid Resuscitation: To prevent dehydration.
Prognostic Assessment: Early identification of severe pancreatitis is crucial.
Scoring Systems:
Ranson Criteria
- Predicts severity and mortality, particularly in alcohol-related pancreatitis.
- Parameters:
 - Initial: Age > 55 years, white blood cell count > 16,000/mm³, blood glucose > 200 mg/dL, serum LDH > 350 IU/L, AST > 250 IU/L.
 - Within 48 hours: Hematocrit drop > 10%, blood urea nitrogen (BUN) rise > 5 mg/dL, serum calcium < 8 mg/dL, base deficit > 4 mEq/L, fluid sequestration > 6 liters, partial pressure of oxygen (PaO₂) < 60 mmHg.
APACHE II (Acute Physiology and Chronic Health Evaluation II)
- Assesses the severity of general critical illness.
- Parameters: 12 physiological variables, including body temperature, mean arterial pressure, heart rate, respiratory rate, oxygenation, pH, serum sodium and potassium, creatinine, hematocrit, and white blood cell count; also includes age and chronic health conditions.
HAPS (Harmless Acute Pancreatitis Score)
- Identifies mild cases of acute pancreatitis early.
- Parameters:
 - Absence of peritonitis.
 - Normal hematocrit.
 - Normal serum creatinine.
 - Age < 55 years.
SIRS (Systemic Inflammatory Response Syndrome)
- Detects inflammation that may lead to sepsis.
- Parameters: At least 2 out of 4:
 - Temperature < 36°C or > 38°C.
 - Heart rate > 90 beats/min.
 - Respiratory rate > 20 breaths/min or PaCO₂ < 32 mmHg.
 - White blood cell count < 4,000/mm³ or > 12,000/mm³, or >10% immature (band) forms.
SOFA (Sequential Organ Failure Assessment)
- Assesses organ dysfunction in critically ill patients.
- Parameters: Evaluates 6 body systems: respiratory, coagulation, liver, cardiovascular, central nervous system, and renal.
BISAP (Bedside Index for Severity in Acute Pancreatitis)
- Early predictor of pancreatitis severity and mortality.
- Parameters:
 - B: BUN > 25 mg/dL.
 - I: Impaired mental status (GCS < 15).
 - S: SIRS present.
 - A: Age > 60 years.
 - P: Presence of pleural effusion.
CTSI (Computed Tomography Severity Index for Acute Pancreatitis)
- Uses CT imaging to assess the severity of acute pancreatitis.
- Parameters: Extent of pancreatic inflammation, presence of pancreatic necrosis, and presence of fluid collections or other complications.
