Study Notes
Liver Tumours
- Non-neoplastic lesions can mimic neoplasms, such as cysts, haemangiomas, regenerative tumour-like lesions, and abscesses.
- Depending on the tissue type of origin, malignant tumours in the liver can include carcinomas, sarcomas, and lymphomas.
- Primary liver tumours are classified as benign and malignant.
- Benign tumours include:
- Hepatic adenoma (associated with anabolic steroids and oral contraceptive pills)
- Bile duct adenoma
- Haemangioma
- Malignant tumours include:
- Hepatocellular carcinoma (HCC)
- Intrahepatic cholangiocarcinoma
- Haemangiosarcoma (rare)
- Benign tumours include:
- Secondary liver tumours, or liver metastases, are the most common type of liver tumour in Europe and North America.
- Sources of metastases include primary tumours in the gastrointestinal tract, lungs, and breasts.
- Liver metastases can obstruct bile flow, leading to a rise in alkaline phosphatase levels and, in later stages, bilirubin accumulation and jaundice.
- Immunohistochemistry is used for the histological diagnosis of liver metastases.
- Markers used for identification:
- CK20, CDX2 for large intestine
- TTF1 for lung
- S100, Melan A, HMB, SOX10 for melanoma
- Markers used for identification:
Hepatocellular Carcinoma (HCC)
- HCC is relatively uncommon in Europe and North America, but more common in East and Southeast Asia and Africa.
- Associated with cirrhosis and chronic hepatitis (over 90% of cases).
- Can occur in non-cirrhotic fibrotic HBV livers.
- Presentation:
- In high incidence areas: co-presents with or precedes cirrhosis, in relatively young patients.
- In low incidence areas: decompensation of cirrhosis, with around 3% HCC/year, vague and changing symptoms.
- Diagnosis:
- Radiology: US, specific contrast-enhanced CT and MRI protocols
- Assessment of nodules in cirrhosis: nodules larger than 1cm or those that are enlarging
- Alpha-fetoprotein (AFP): used as a tumour marker
- Biopsy: rarely necessary
- Screening:
- High-risk patients (compensated cirrhosis): every 6-12 months, including US and AFP blood tests.
- AFP blood test alone: not specific or sensitive enough for accurate diagnosis.
- Prevention:
- Treatment of underlying chronic liver disease.
- Prevention of chronic liver disease (HBV vaccination).
- Treatment:
- Resection: if detected early
- Orthotopic liver transplantation (OLT)
- Local ablative treatments: radiofrequency ablation, arterial chemo-embolization
- Prognosis: depends on stage, degree of liver function impairment, and co-morbidity.
- Typically poor, but in selected cases, 5-year survival can reach 50%.
- Aetiology:
- Cirrhosis (HBV, HCV, HFE more prevalent than other causes of cirrhosis).
- Chronic HBV: directly oncogenic
- Aflatoxins: fungal contaminants of food stores
Cholangiocarcinoma
- Adenocarcinoma arising from bile duct epithelium.
- Classified as intrahepatic or extrahepatic.
- **Commonest site: **hilum of the liver.
- Klatskin tumour: obstructing bifurcation of the common hepatic duct (CHD).
- Intrahepatic cholangiocarcinoma: constitutes a minority of primary liver malignancies (10%).
- Associations:
- Primary sclerosing cholangitis (PSC)
- Rare: chronic fluke infestation, congenital biliary abnormalities.
- Diagnosis: difficult and often late; outcome is poor.
- Treatment: surgical resection in selected cases; typically palliative obstruction with stent placement.
Pancreas
- Retroperitoneal location.
- Two distinct embryological components:
- Exocrine (98%): produces digestive enzymes.
- Endocrine (2%): islets of Langerhans, secreting hormones.
- Exocrine part: composed of glandular acini grouped into lobules.
- Exocrine secretions: drained via ducts, joining to form the pancreatic duct.
Pancreatic Tumours
- Exocrine pancreas:
- Malignant: pancreatic (ductal) adenocarcinoma.
- Other less common tumours: sometimes cystic, can be benign or have intermediate behaviour.
- Precursors to pancreatic cancer: some recognized as precursors.
- Endocrine:
- Pancreatic neuroendocrine tumours: rare.
- Behaviour: difficult to predict.
- Classification: by hormone type produced.
- Hormone: may cause clinical symptoms.
- Association with MEN type 1 syndrome: associated with parathyroid hyperplasia and pituitary adenomas.
Pancreatic Carcinoma
- Adenocarcinoma arising from pancreatic ducts.
- Common: 5th/6th most common cause of cancer deaths.
- Malignant: more common in men (M>F), predominantly in individuals over 60 years old.
- Location: 60-70% originate from the head of the pancreas, the rest from the body and tail.
- Spread:
- Direct local: peritoneum (vessels, nerves), duodenum, CBD = 'locally advanced'.
- Lymph nodes or liver: approximately 50% have metastases at diagnosis.
- Risk factors:
- Smoking, diabetes mellitus, chronic pancreatitis: relatively weak.
- Family history: 5%, considered a stronger risk factor..
- Symptoms: typically only become apparent with advanced disease.
- Anorexia, weight loss.
- Painless obstructive jaundice: tumours in the head of the pancreas.
- Vague abdominal pain: may radiate to the back.
- Rare: palpable mass, thrombotic tendency.
- Migratory thrombophlebitis: Trousseau’s sign.
- Diagnosis:
- CA 19-9: serum marker for pancreatico-biliary cancer.
- Not useful for diagnosis: primarily used for monitoring response and detecting relapse.
- Imaging: US, CT, EUS
- Fine-needle aspiration cytology (FNA): via EUS
- Avoid unnecessary invasive investigation in the majority of cases.
- CA 19-9: serum marker for pancreatico-biliary cancer.
- Prognosis:
- 5-year survival: lower in men and the older age group.
- Late presentation, vague symptoms contribute to poor prognosis.
- Clinical problem: gall bladder "polyps" often identified on US.
- Question: could they be neoplasms of the gall bladder (adenomas or carcinomas)?
- Small/non-progressive polyps: likely harmless non-neoplastic cholesterol "polyps".
Causes of Extrahepatic Bile Duct Obstruction
- Gallstones in the common bile duct.
- Tumour:
- Adenocarcinoma of the pancreas.
- Extra-hepatic bile duct adenocarcinoma.
- Benign stricture: post-operative or caused by primary sclerosing cholangitis (PSC).
- Mass outside CBD/CHD compressing duct:
- Mirizzi syndrome: external compression from a stone in the neck/cystic duct of the gallbladder.
- Primary tumour or metastases in lymph nodes.
Extrahepatic Bile Duct Obstruction
- Courvoisier's law: historical interest only, referring to an enlarged, non-tender gallbladder.
- Investigation:
- US: shows dilated ducts proximal to the obstruction.
- Cause: may require further investigation using MRCP or EUS.
- ERCP: may be used for diagnosis and treatment.
- Treatment aims to decompress the bile duct and address the underlying cause:
- Stones:
- ERCP with sphincterotomy and stone removal.
- Common bile duct exploration: laparoscopic or open surgery.
- Stricture: stent placement.
- Tumour: stent placement, usually via ERCP.
- Stones:
Ascending (Acute) Cholangitis
- Infection in static, obstructed bile.
- Charcot's triad: high fever, pain, and jaundice.
- Reynolds' pentad: Charcot's triad plus hypotension and altered mental state.
- Requires urgent decompression.
Hepatic Abscess
- Biliary tract disease with ascending infection: most common cause.
- Seeding from systemic sepsis: may occur in some cases.
- Historically: spread via the portal vein from intra-abdominal sepsis.
- Treatment: drainage and antibiotics.
- Amoebic abscess: a distinct cause.
Acute Pancreatitis
- Acute inflammation of the pancreas.
- Incidence: 10-20/million, mortality rate of approximately 5% (higher in severe cases), can occur as single or recurrent attacks.
- Pathogenesis:
- Premature activation of pancreatic enzymes within the pancreas.
- Irreversible cascade of auto-digestion once initiated.
- Systemic inflammatory response syndrome (SIRS) if severe.
- Causes:
- Obstructing stone at the lower end of the common bile duct: causing reflux of bile and concentration of pancreatic juices.
- Alcohol: direct toxic effect.
- Mechanism: premature activation of pancreatic enzymes leads to auto-digestion.
Severity of Acute Pancreatitis
- Mild Acute Pancreatitis (80% of cases):*
- Self-limiting disease.
- Interstitial oedematous acute pancreatitis on imaging, non-necrotizing.
- Severe Acute Pancreatitis (20% of cases):*
- Necrotizing inflammation of the pancreas and surrounding tissue (peripancreatic fat).
Effects of Severe Acute Pancreatitis
- Systemic inflammatory response syndrome (SIRS): hypovolemia, hypotension, acute respiratory distress syndrome (ARDS), acute renal failure, disseminated intravascular coagulation (DIC).
- Hypocalcemia, hyperglycemia, ileus.
- Local complications:
- Extensive necrosis (acute necrotic collection), risk of secondary infection.
- Later: pseudocyst, fistula formation.
- Mortality:
- First week: 50% due to SIRS and complications.
- Second week: 50% due to necrosis and sepsis.
###Causes of Acute Pancreatitis
- **Gallstones** (50% of cases, both men and women).
- **Alcohol** (a very common cause).
- **Post-ERCP** (5%).
- **Idiopathic** (10%), biliary microlithiasis.
- **Uncommon causes (5%):**
- **Trauma, ischemia, major surgery.**
- **Drugs, viral infections.**
- **Hypercalcemia, hyperlipidemia.**
- **Hereditary pancreatitis.**
Diagnosis of Acute Pancreatitis
- **Symptoms**: epigastric pain that may radiate into the back, "acute abdomen" often seen by surgeons.
- **Severe cases**: differential diagnosis - myocardial infarction (MI), ruptured abdominal aortic aneurysm (AAA), perforated or ischemic abdominal organ.
- **Blood tests**:
- **Amylase**: elevated to more than 3 times normal.
- **Amylase**: short half-life.
- **Lipase**: might be used in the future, if amylase inconclusive, consider radiology.
- **Aim:** identify the cause and avoid immediate laparotomy.
Chronic Pancreatitis
- Patchy, irreversible fibrosis with ongoing inflammation.
- Impaired pancreatic function: exocrine function more severely affected than endocrine.
- Distortion of ductal system: strictures, dilation, cysts behind strictures, pancreatic ductal stones.
- Causes:
- Alcohol: a major cause.
- Idiopathic: unknown origin.
- Childhood causes: including cystic fibrosis.
- Cystic fibrosis: more typically associated with pancreatic insufficiency due to damage but without clinical “chronic pancreatitis.”
Chronic Pancreatitis
- Symptoms:
- Dull pain: epigastric, radiating to the back.
- Weight loss.
- Steatorrhoea and malabsorption.
- Secondary diabetes mellitus.
- Treatment: analgesia (opioids), enzyme supplements.
- Diagnosis:
- Difficult: often a diagnosis of exclusion.
- Amylase: not useful.
- Tests of pancreatic function: not routine.
- Imaging: used in advanced disease.
Pancreatic Pseudocyst
- **Collection of pancreatic fluid** in disrupted tissue within or adjacent to the pancreas.
- **Defined wall** but not a true cyst (lacks epithelial lining).
- **Causes:** acute or chronic pancreatitis, pancreatic surgery, or trauma.
- **Complications:** pain/pressure, infection, erosion with fistula or blood vessel damage.
- **Treatment:** aspiration or drainage by endoscopy or surgery.
