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)
