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)
