Clinical Case Analysis: 54-Year-Old Male with Obstructive Jaundice + Palpable Gallbladder

DIAGNOSIS

• Persistently and progressively deepening jaundice (obstructive, not fluctuating)
• Palpable, non-tender, soft cystic gallbladder - this is Courvoisier's Law (positive)
• Significant constitutional features - anorexia, gross weight loss

Courvoisier's Law: "If the gallbladder is palpable and the patient is jaundiced, the obstruction of the bile duct is unlikely to be due to a stone." This is because chronic cholelithiasis causes a fibrosed, thickened, non-distensible gallbladder - whereas a neoplastic obstruction occurring in a previously normal gallbladder allows it to dilate passively.

PART 1: DETAILED WORK-UP (5 Marks)

A. History (detailed points)

• Duration, onset, progression of jaundice - whether painless or painful
• Nature of pain - dull aching (pancreatic cancer) vs colicky (stone)
• Colour of stools (pale/clay-coloured = obstructive) and urine (dark = conjugated bilirubin)
• Pruritus (bile salts in skin)
• Symptoms of cholangitis: Charcot's triad (pain + fever + jaundice) or Reynold's pentad
• Weight loss quantification and time frame
• Past history of gallstones, pancreatitis, alcohol, smoking
• Family history of pancreatic malignancy

B. Clinical Examination

• Icterus severity - scleral, skin, mucous membranes
• Confirm: Non-tender, soft, cystic, palpable gallbladder (Courvoisier's sign)
• Hepatomegaly (smooth, tender - suggests biliary obstruction; nodular - liver secondaries)
• Splenomegaly (portal hypertension)
• Ascites (peritoneal deposits)
• Virchow's node (left supraclavicular lymphadenopathy - Sister Mary Joseph nodule)
• Cachexia, muscle wasting

C. Investigations

Routine (Pre-op preparation):

Liver Function Tests (LFTs):

• Total & direct bilirubin - markedly raised, predominantly direct (conjugated)
• Alkaline phosphatase - very high (marker of biliary obstruction)
• GGT - elevated
• AST/ALT - mildly elevated (secondary hepatocellular damage)
• Serum albumin - may be reduced

Imaging Workup:

Tumour Markers:

• CA 19-9 - primary marker for pancreatic carcinoma (sensitivity ~80%)
• CEA - less specific but useful
• AFP, CA-125 if cholangiocarcinoma considered

PART 2: PREPARATION FOR GENERAL ANAESTHESIA (5 Marks)

1. Correct Coagulopathy

• Obstructive jaundice prevents fat-soluble vitamin (especially Vitamin K) absorption
• Give Vitamin K 10 mg IM/IV for 3-5 days; monitor PT/INR and correct to within 2 seconds of normal
• Fresh Frozen Plasma (FFP) if urgent correction needed

2. Relieve Jaundice Preoperatively

• Biliary decompression before major surgery reduces hepatorenal complications:
  • Endoscopic biliary stenting (ERCP-guided) - preferred
  • Percutaneous Transhepatic Biliary Drainage (PTBD) if ERCP fails
• Target: Bring bilirubin < 10 mg/dL before surgery

3. Prevent Hepatorenal Syndrome

• Obstructive jaundice causes renal tubular toxicity from bile salts
• IV fluid hydration: adequate preoperative hydration with Normal Saline
• Monitor urine output (target >0.5 mL/kg/hr)
• Mannitol infusion intraoperatively (10% mannitol 200 mL IV) to maintain renal tubular flow
• Avoid nephrotoxic drugs (NSAIDs, aminoglycosides)

4. Nutritional Optimization

• Patient has gross weight loss and anorexia
• Correct with high-protein, high-calorie diet or parenteral nutrition if necessary
• Correct anaemia if Hb < 10 g/dL (packed red cell transfusion)
• Correct hypoalbuminemia (albumin infusion if <2.5 g/dL)

5. Treat Cholangitis

• Broad-spectrum IV antibiotics (covering gram-negative enterics and anaerobes):
  • Piperacillin-tazobactam, or
  • Cephalosporin + Metronidazole
• Start 48-72 hours preoperatively

6. Specific Anaesthetic Considerations

• Blood cross-matching (major blood loss expected in Whipple's)
• Glucose monitoring (pancreatic endocrine insufficiency)
• Avoid halothane (hepatotoxic) - prefer isoflurane/sevoflurane
• Central line + arterial line for monitoring
• Epidural analgesia setup for postoperative pain

7. Consent & Counselling

• Explain diagnosis, prognosis, surgical risk
• High-risk patient: jaundice + malnutrition + age 54

PART 3: OUTLINE OF TREATMENT (5 Marks)

A. CURATIVE TREATMENT

• Standard operation for resectable carcinoma of head of pancreas / periampullary carcinoma
• Resects: Head of pancreas + duodenum + lower CBD + gallbladder + antrum of stomach (classic Whipple's) or with pylorus preservation
• Reconstruction: Pancreaticojejunostomy + Hepaticojejunostomy + Gastrojejunostomy
• Resectability criteria: No involvement of portal vein, SMA, or distant metastases
• Only ~15-20% of pancreatic cancers are resectable at presentation

• Gemcitabine-based chemotherapy
• Chemoradiotherapy in selected cases

B. PALLIATIVE TREATMENT

1. Relieve obstructive jaundice
2. Relieve gastric outlet obstruction
3. Relieve pain

SUMMARY TABLE

• This is a 5+5+5 = 15 mark question requiring equal depth in workup, pre-op prep, and treatment
• Always mention Courvoisier's law in the diagnosis
• Preoperative correction of Vitamin K / coagulopathy is the most frequently tested step
• Whipple's procedure = curative; biliary bypass + stenting = palliative
• Palliation addresses three problems: jaundice, duodenal obstruction, and pain
