    Study Notes

    Pancreatitis

    • Pancreatitis is an inflammation of the pancreas, often associated with the release of inflammatory cytokines and pancreatic enzymes.
    • It can occur at any age.
    • Mortality rate for pancreatitis is approximately 10%.
    • Accounts for 3% of hospital admissions with related abdominal pain.

    Causes of Pancreatitis

    • Gallstones are the most common cause, responsible for 80% of cases.
    • Alcohol is also a significant contributor.
    • Other causes include:
      • Trauma
      • Steroids
      • Mumps
      • Autoimmune disorders
      • Scorpion stings
      • Hypertriglyceridemia/Hypercalcemia
      • ERCP
      • Medications (e.g., thiazides)

    Pancreatitis Pathogenesis

    • It involves an autodigestive process where pancreatic enzymes are activated due to injury, causing inflammation and the release of cytokines.
    • This leads to both local and systemic inflammatory responses.

    Pancreatitis Symptoms

    • Epigastric pain is a primary symptom, often rapid and radiating to the back, which can be relieved by leaning forward.
    • Nausea and vomiting are also common.

    Pancreatitis Signs

    • Dehydration
    • Epigastric guarding
    • Tachycardia, tachypnoea, and mild pyrexia
    • If cholangitis is present (bile duct inflammation due to gallstones), Charcot's triad may be present:
      • Jaundice
      • Pyrexia
      • Right upper quadrant pain
    • Cullen's sign (peri-umbilical bruising) and Grey Turner's sign (flank bruising) can be seen in hemorrhagic pancreatitis.

    Pancreatitis Severity Stratification

    • The Glasgow (IMRIE) Criteria are used to determine severity.
    • It assesses:
      • PaO2
      • Neutrophils
      • Calcium
      • Enzymes (Lipase, AST)
      • Albumin
    • A score exceeding 3 indicates severe disease.

    Workup & Investigations for Pancreatitis

    • Physical examination, vital signs, and bedside investigations, including:
      • Blood glucose
      • Urine dipstick (+/- beta hCG)
    • Imaging:
      • Chest X-ray (for free air under the diaphragm)
      • Ultrasound (for gallstones)
      • CT scan (after 3 days to assess severity and complications)
    • Laboratory tests:
      • Serum amylase/lipase
      • Urinary amylase
      • FBC, CRP, LFTs, U&E, LDH, Calcium, Albumin, Glucose
      • Coagulation profile
      • ABG/VBG (lactate)

    Acute Pancreatitis Management

    • Oxygen
    • Intravenous fluids with urine output monitoring
    • Analgesia
    • Monitoring vital signs
    • Glasgow IMRIE score assessment (repeated at 48 hours)
    • Management of systemic and local complications
    • Introduction of feeding once possible
    • Antithrombotic prophylaxis
    • Awareness of alcohol withdrawal (chlordiazepoxide + pabrinex)
    • Antibiotics for pancreatic necrosis (e.g., meropenem)

    Pancreatitis Complications

    • ARDS
    • Pseudocyst formation
    • Pancreatic abscess
    • Necrotizing pancreatitis
    • Acute kidney injury
    • Pancreatic hemorrhage
    • Chronic pancreatitis
    • Mortality
    • Metabolic (hyperglycemia, hypocalcemia)
    • Necrosis of transverse colon

    Necrotizing Pancreatitis

    • Characterized by two phases:
      • Phase 1-2 weeks: Severe systemic inflammatory response syndrome (SIRS) due to cytokine release
      • Phase 2+ weeks: Sepsis-related complications due to infected pancreatic necrosis

    Surgical Management of Necrotizing Pancreatitis

    • Infected pancreatic necrosis is a significant contributor to mortality associated with acute pancreatitis.
    • Management involves:
      • Severity assessments using Glasgow criteria and markers like C-reactive protein and APACHE II score
      • Dynamic CT scanning
      • Percutaneous needle aspiration to determine if necrosis is infected or sterile
      • Surgical intervention for infected necrosis, while non-operative management may be considered for sterile necrosis.

    Preventing Further Pancreatitis Episodes:

    • For gallstone-related pancreatitis, there is a 30% risk of recurrence within three months.
    • Management includes:
      • Endoscopic ultrasound (EUS), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP)
      • Cholecystectomy, usually performed 6 weeks after an acute gallstone-induced pancreatitis episode.
    • For alcohol-related pancreatitis, alcohol withdrawal is crucial using psychological and pharmacological approaches.
    • Screen for underlying conditions such as hypercalcemia, hyperlipidemia, or pancreatic neoplasms as they may cause pancreatitis.

    Chronic Pancreatitis

    • Characterized by fibrosis affecting pancreatic nerves (causing pain) and pancreatic ducts, leading to obstruction and ductal dilation.
    • This fibrosis can damage the islets and glandular tissue, causing exocrine and endocrine failure.
    • Common complications include:
      • Pseudocyst formation
      • Stones in the pancreatic duct
      • Strictures

    Cause of Chronic Pancreatitis

    • Recurring episodes of acute pancreatitis
    • Pancreatic duct obstruction due to:
      • Pancreatic head tumors or cysts
      • Pancreatic duct strictures
      • Congenital anomalies
      • Cystic fibrosis
    • Autoimmune diseases
    • Idiopathic causes

    Chronic Pancreatitis Treatment

    • Addressing the underlying cause:
      • Discontinuation of alcohol
      • Cholecystectomy
      • Management of autoimmune diseases
    • Dietary modifications:
      • Limiting fat intake
    • Enzyme supplementation:
      • Creon
    • Analgesia
    • For intractable pain:
      • Endoscopic therapy
      • Celiac nerve block
      • Surgical intervention, including Whipple's procedure.

    Whipple's Procedure

    • A surgical intervention commonly performed in patients with chronic pancreatitis experiencing intractable pain.

    Pancreatic Cancer

    • The tumor doubling time is 60 days.
    • 85% of cases are unresectable at diagnosis.
    • Patients with pancreatic cancer who undergo bypass surgery typically have a mean survival of only six months.
    • 90% of patients with pancreatic adenocarcinoma die within 12 months.

    Courvoisier's Law

    • A palpable, painless gallbladder in a jaundiced patient is less likely due to gallstone disease and may suggest pancreatic cancer.

    Risk Factors for Pancreatic Cancer

    • Age: 80% of cases occur in the 6th and 7th decades of life.
    • Smoking
    • Alcoholism
    • Diabetes
    • Chronic pancreatitis

    Clinical Features of Pancreatic Cancer

    • Progressive jaundice
    • Vomiting (due to duodenal obstruction)
    • Ascites
    • Back pain
    • Anorexia
    • Weight loss
    • Sister Mary Joseph nodule

    Pancreatic Cancer Management

    • Palliative care:
      • Biliary stent
      • Gastro-jejunostomy
      • Coeliac axis block
    • Surgical intervention:
      • Whipple's procedure: Resection of the head and neck of the pancreas, part of the stomach, duodenum, gallbladder, and bile duct, along with lymph node clearance.

    Pancreatitis Causes

    • Gallstones are the most common cause of pancreatitis, accounting for 80% of cases.
    • Alcohol abuse is the second most common, responsible for around 20% of cases.
    • Other causes include:
      • Trauma
      • Steroids
      • Mumps
      • Autoimmune disorders
      • Scorpion stings
      • Hypertriglyceridemia/Hypercalcemia
      • ERCP (Endoscopic Retrograde Cholangiopancreatography)
      • Medications (e.g., thiazides)
      • Idiopathic (unknown cause)
