INVESTIGATIONS

A. ABG and Electrolytes - INTERPRETATION

ParameterValueNormalInterpretation
pH7.567.35-7.45Alkalemia
pO296 mmHg80-100Normal
pCO248 mmHg35-45Elevated (respiratory compensation)
HCO336 mEq/L22-26Markedly elevated

Na+128 mEq/L135-145Hyponatraemia
K+2.8 mEq/L3.5-5.0Hypokalemia
Cl-80 mEq/L98-106Hypochloraemia
ABG Interpretation: Hypochloraemic, Hypokalaemic Metabolic Alkalosis with respiratory compensation.
Mechanism: Persistent vomiting of gastric acid (HCl) → loss of H+ and Cl- → bicarbonate accumulates in blood → metabolic alkalosis. Volume depletion activates renin-angiotensin-aldosterone → worsens K+ loss from kidney → hypokalemia. (Costanzo Physiology, p. BOX 7.2)

C. Barium Meal X-ray Findings

The barium meal shows:
  • Grossly dilated, distended stomach - the stomach has an enormous rounded opacity occupying much of the upper abdomen (the "barium lake" or retained barium sign)
  • Failure of gastric emptying - barium is retained in the stomach
  • Irregular narrowing at the antro-pyloric region
  • No passage of barium into the duodenum during the study
Barium Meal Conclusion: Gastric outlet obstruction - consistent with antro-pyloric lesion.

D. UGI Endoscopy Findings

The 6-panel endoscopy images show:
  • Dark retained old food material in the stomach (top left) - classic sign of GOO
  • Whitish exudate coating gastric mucosa (top right)
  • Narrowed, deformed pyloric channel with convergent mucosal folds (middle and lower panels)
  • Clipping visible around a pyloric/antral lesion - suggests biopsy clips / haemostatic clips placed at the time of scope
  • Irregular pyloric mucosa with ulceration
Endoscopy Conclusion: Antro-pyloric mass/ulcero-proliferative lesion causing gastric outlet obstruction. Biopsy mandatory - most likely carcinoma stomach vs. pyloric ulcer with stenosis.

MANAGEMENT

Step 1 - Resuscitation and Pre-operative Stabilisation

  1. IV Access - two wide-bore cannulae
  2. Nasogastric tube insertion (wide-bore) - gastric decompression; lavage the stomach until clear (Bailey & Love, p.1190)
  3. IV Fluids - Isotonic Normal Saline (0.9% NaCl) with KCl supplementation - corrects dehydration, hyponatraemia and hypochloraemia
    • Note: Do NOT use Ringer's lactate (avoid lactate in metabolic alkalosis)
  4. Potassium replacement - IV KCl 20 mEq in each litre of saline; monitor K+ twice daily
  5. Urine output monitoring - catheterize, target UO >0.5 ml/kg/hr
  6. Blood glucose monitoring - patient is diabetic; manage with insulin sliding scale
  7. Serial ABG - to monitor correction of metabolic alkalosis
  8. Nutritional support - total parenteral nutrition (TPN) if surgery delayed; correct malnutrition
  9. PPI infusion - IV Pantoprazole / Omeprazole 40 mg BD (reduces acid secretion, decreases gastric secretions)

Step 2 - Definitive Investigation

  • Endoscopic biopsy with HPE - to confirm malignancy vs. benign peptic ulcer (Bailey & Love, p.1190)
  • CT scan abdomen and pelvis with contrast - staging, assess resectability, lymph node status, liver metastasis
  • H. pylori testing - Rapid urease test (CLO test) / serology / histology

Step 3 - Definitive Surgical Management

If Carcinoma Stomach (Antro-pyloric):

  • Staging laparoscopy first to exclude peritoneal metastasis
  • Curative intent:
    • Subtotal/distal gastrectomy (D2 lymph node dissection) - if resectable
    • Reconstruction by Billroth I (gastroduodenostomy) or Billroth II (gastrojejunostomy) or Roux-en-Y
    • Perioperative chemotherapy (FLOT / ECF regimen)
  • Palliative intent (unresectable):
    • Gastrojejunostomy - surgical bypass for GOO relief
    • Endoscopic duodenal/antral stenting (self-expanding metal stent - SEMS)

If Benign Pyloric Stenosis (PUD):

  • H. pylori eradication - Triple therapy (PPI + Amoxicillin + Clarithromycin) / Quadruple therapy
  • Endoscopic balloon dilatation - 85% amenable; 40% sustained response at 3 months (Mulholland & Greenfield, p.2269)
  • Surgery if dilatation fails:
    • Vagotomy + Gastrojejunostomy (most common drainage procedure)
    • Vagotomy + Antrectomy - low ulcer recurrence, good gastric emptying (Mulholland & Greenfield, p.2269)
    • Jaboulay gastroduodenostomy - when duodenal scarring is extensive (Sabiston, p.1785)

VIVA QUESTIONS AND ANSWERS


Q1. What is the classical triad of features on examination in GOO?

A. Visible gastric peristalsis, succussion splash, and dilated stomach on imaging (barium lake sign).

Q2. What is the ABG pattern in GOO due to peptic ulcer disease?

A. Hypochloraemic, hypokalaemic metabolic alkalosis with respiratory compensation (raised pCO2). This patient's ABG confirms it: pH 7.56, HCO3 36, Cl 80, K 2.8. Loss of HCl in vomitus is the mechanism. (Costanzo Physiology, BOX 7.2)

Q3. Why is the urine paradoxically acidic in GOO?

A. In prolonged GOO with severe dehydration, the kidney retains Na+ and preferentially excretes K+ and H+ under aldosterone drive (secondary hyperaldosteronism from volume depletion). Despite systemic alkalosis, the urine becomes acidic - called paradoxical aciduria.

Q4. What fluid and electrolyte regimen is used to correct GOO metabolic disturbance?

A. IV isotonic Normal Saline (0.9% NaCl) with KCl supplementation. Replacing NaCl and water restores ECF volume, suppresses aldosterone, and allows the kidney to excrete excess HCO3-, correcting the alkalosis. Do NOT use Hartmann's/Ringer's Lactate. (Bailey & Love, p.1190)

Q5. What is the most important investigation in GOO and why?

A. Upper GI endoscopy with biopsy - it is mandatory to exclude malignancy (gastric cancer is now more common than PUD as a cause of GOO). Endoscopy also allows balloon dilatation, H. pylori testing, and staging biopsies.

Q6. What are the causes of GOO?

A.
  • Benign: Chronic PUD with pyloric stenosis, post-surgical stricture, Crohn's disease, polyps, TB
  • Malignant: Carcinoma stomach (antro-pyloric), carcinoma head of pancreas, carcinoma duodenum, lymphoma
  • Other: External compression, bezoar, gallstone in duodenum (Bouveret syndrome)

Q7. What does the barium meal show in GOO?

A. Grossly dilated stomach ("barium lake"), retained barium with food residue, irregular narrowing at the pyloro-duodenal junction, and failure/delay in gastric emptying (barium retained at 4-6 hours).

Q8. What surgical operations are done for benign GOO?

A.
  • Vagotomy + Drainage (pyloroplasty or gastrojejunostomy) - most common
  • Vagotomy + Antrectomy - gold standard, lowest recurrence
  • Jaboulay gastroduodenostomy - side-to-side anastomosis when duodenum is scarred
  • Endoscopic balloon dilatation - first-line in early cases

Q9. What is the significance of "previous day's undigested food" in vomitus?

A. This is pathognomonic of gastric outlet obstruction. Normal gastric emptying occurs in 2-4 hours. Vomiting food eaten the day before indicates gross delay in gastric emptying due to mechanical or functional outlet obstruction.

Q10. What are the metabolic abnormalities in malignant GOO vs. benign GOO?

A. In benign GOO (PUD), there is high acid secretion; vomiting causes significant loss of HCl, so metabolic alkalosis is pronounced. In malignant GOO (carcinoma stomach), there is relative hypochlorhydria due to destruction of parietal cells by tumor, so the metabolic disturbance is less pronounced. (Bailey & Love, p.1189)

Q11. What is the role of H. pylori in GOO?

A. H. pylori infection causes chronic active gastritis → duodenal/peptic ulceration → repeated cycles of ulceration and healing → fibrosis and pyloric scarring → GOO. H. pylori eradication is mandatory in benign GOO and can lead to resolution in early cases.

Q12. What are the risk factors for carcinoma stomach seen in this patient?

A.
  • Age - 58 years (peak incidence 6th-7th decade)
  • Male gender
  • Heavy smoking - 80 pack-years (strong association)
  • Alcohol use - 25 years
  • Type 2 Diabetes - associated increased risk
  • (H. pylori infection would need to be tested - major risk factor)

Q13. What is the staging investigation for carcinoma stomach?

A.
  1. CT chest/abdomen/pelvis with contrast - assess T, N, M staging
  2. Staging laparoscopy - detect peritoneal seeding (CT misses ~30%)
  3. PET-CT - for distant metastasis
  4. Endoscopic Ultrasound (EUS) - T staging accuracy, locoregional nodes
  5. Tumor markers: CEA, CA 19-9, CA 72-4

Q14. What is the significance of D2 lymphadenectomy in gastric cancer?

A. D2 dissection removes perigastric nodes (N1) AND nodes along the celiac axis and its branches (N2). It provides better staging and improved survival compared to D1. It is the standard of care in curative resection for gastric cancer, based on large trials (Dutch D1D2 trial showed long-term survival benefit for D2).

Q15. Why does this patient have anaemia?

A. Hb of 10 g/dl in this setting is likely due to:
  • Chronic disease/malnutrition - 7 kg weight loss in 1 month, poor nourishment
  • Iron deficiency from bleeding ulcer/tumour (though no overt haematemesis/melaena)
  • Poor oral intake from early satiety and vomiting

Key Interpretation:
  • Markedly elevated amylase (523) and lipase (459) confirm pancreatitis / pancreatic pathology
  • Serum amylase is elevated in approximately 50% of patients with a pseudocyst - this does not indicate recurrent pancreatitis but reflects continued pancreatic enzyme leakage (Current Surgical Therapy 14e)
  • Elevated GGT and ALP - consistent with chronic alcoholic liver disease / biliary obstruction by pseudocyst
  • Elevated ESR, mildly prolonged INR - chronic inflammatory state, nutritional impact of alcoholism
  • Mild hyponatraemia - vomiting + poor intake

B. Imaging Required

USG Abdomen (First-Line)

  • Cystic lesion in the pancreatic region - thick-walled, no internal septations (pseudocyst vs. neoplasm)
  • Assessment of biliary tree, liver
  • Doppler for vascular involvement

CECT Abdomen (Investigation of Choice)

  • Defines the size, location, wall thickness, content of the cyst
  • Differentiates pseudocyst from WON (no solid debris in pseudocyst)
  • Sensitivity 82-100%, specificity 98% for diagnosing pseudocysts (Current Surgical Therapy 14e)
  • Assesses surrounding structures, ductal dilation, calcifications

MRCP / MRI Abdomen

  • Delineates ductal communication with the pseudocyst
  • Identifies main duct strictures, disconnected pancreatic duct
  • Guides treatment planning; has largely replaced diagnostic ERCP (Current Surgical Therapy 14e)

EUS + FNA (if diagnosis uncertain)

  • Fluid analysis: high amylase → pseudocyst; high CEA → mucinous neoplasm
  • Cytology to exclude malignancy

MANAGEMENT

Step 1 - General Supportive Measures (Acute Phase)

  1. NPO (nil per oral) - rest the pancreas
  2. IV fluids - isotonic saline or Ringer's lactate, maintain hydration
  3. Analgesia - IV Tramadol / Diclofenac; avoid morphine (causes sphincter of Oddi spasm)
  4. Antiemetics - IV Ondansetron / Metoclopramide
  5. NG tube - if persistent vomiting
  6. Nutritional support - enteral nutrition (nasojejunal tube) preferred over TPN; low-fat diet
  7. Absolute alcohol abstinence - counselling and de-addiction referral
  8. Smoking cessation
  9. Monitor - vitals, urine output, blood glucose (risk of endocrine insufficiency)
  10. PPI - IV Pantoprazole (reduces stimulation of pancreatic secretion by acid)

Step 2 - Watchful Waiting (Conservative)

  • Up to 90% of peripancreatic fluid collections resolve spontaneously within 6 weeks (Current Surgical Therapy 14e)
  • Serial USG / CT at 4-6 week intervals to monitor resolution
  • If asymptomatic and <6 cm - observe conservatively
  • Features suggesting low chance of spontaneous resolution: increasing size >6 weeks, calcifications in pancreatic duct, ductal strictures, multiple cysts, tail location, complex cysts

Step 3 - Intervention (indicated when)

Indications for drainage:
  • Pseudocyst persisting >6 weeks and symptomatic
  • Size >6 cm (controversial; size alone not an absolute indication)
  • Complications: infection, rupture, haemorrhage, biliary obstruction, GOO
  • Increasing size on surveillance

A. Percutaneous Drainage (least invasive)

  • USG or CT-guided pigtail catheter
  • Reserved for: critically ill patients, infected/complicated pseudocysts, not fit for endoscopy/surgery
  • Disadvantage: high re-accumulation rate, risk of pancreaticocutaneous fistula if ductal communication exists (Current Surgical Therapy 14e)

B. Endoscopic Drainage (preferred first-line for eligible patients)

  • Endoscopic cystgastrostomy - drain into stomach; gold standard endoscopic approach
  • EUS-guided transmural drainage - passes through stomach/duodenal wall under USS guidance; lumen-apposing metal stent (LAMS) placed
  • Transpapillary drainage (ERCP + stent) - when pseudocyst communicates with pancreatic duct
  • Success rates comparable to surgery, less invasive (Current Surgical Therapy 14e)

C. Surgical Drainage (gold standard; lowest recurrence ~5%)

  • Internal drainage preferred over external drainage (avoids pancreaticocutaneous fistula)
  • Options:
    • Cystogastrostomy - posterior cystogastrostomy; direct anastomosis between posterior stomach wall and anterior cyst wall; simple, effective
    • Roux-en-Y Cystojejunostomy - ideal internal drainage; Roux limb of jejunum anastomosed to cyst; best for large/complex pseudocysts (Maingot's Abdominal Operations)
    • Cystoduodenostomy - when cyst adherent to duodenum
  • Laparoscopic cystgastrostomy - feasible in experienced centres (Bailey & Love, p.1298)
  • Distal pancreatectomy - for pseudocysts in the tail not amenable to drainage

VIVA QUESTIONS AND ANSWERS


Q1. Define pancreatic pseudocyst.

A. A peripancreatic fluid collection persisting beyond 4 weeks after interstitial edematous pancreatitis, enclosed in a well-defined wall of fibrotic/granulation tissue containing amylase-rich fluid and no epithelial lining (hence "pseudo" - no true epithelial wall). It is the most common cystic lesion of the pancreas. (Current Surgical Therapy 14e)

Q2. What is the Atlanta Classification of pancreatic fluid collections?

A.
  • Interstitial edematous pancreatitis (<4 weeks) → Acute Pancreatic Fluid Collection (APFC)
  • Interstitial edematous pancreatitis (>4 weeks) → Pancreatic Pseudocyst
  • Necrotizing pancreatitis (<4 weeks) → Acute Necrotic Collection (ANC)
  • Necrotizing pancreatitis (>4 weeks) → Walled-Off Necrosis (WON)

Q3. What is the most common cause of pancreatic pseudocyst?

A. Alcohol-induced chronic pancreatitis (most common in India/developing world). Other causes: gallstone pancreatitis, abdominal trauma, post-ERCP, idiopathic.

Q4. Why are both amylase and lipase elevated in this patient despite the pseudocyst being the main finding?

A. Serum amylase is elevated in approximately 50% of patients with pseudocyst - not because of a new episode of pancreatitis but due to ongoing enzymatic leak from the pseudocyst or an underlying ductal abnormality. Lipase is more specific for pancreatic disease (normal upper limit 78 U/L; patient has 459). (Current Surgical Therapy 14e)

Q5. What is the investigation of choice for diagnosing a pancreatic pseudocyst?

A. CECT Abdomen - sensitivity 82-100%, specificity 98%. Shows a well-defined, thin-walled, homogeneous fluid-density lesion in or around the pancreas with no internal septations or solid components. MRCP is used to assess ductal anatomy and communication.

Q6. How do you differentiate pseudocyst from cystic neoplasm (e.g., MCN)?

A.
FeaturePseudocystMucinous Cystic Neoplasm
HistoryPancreatitis / alcohol / traumaNo pancreatitis history
WallThin, uniformThick, septated, may have nodules
Fluid CEALow (<5 ng/ml)High (>192 ng/ml)
Fluid AmylaseHighLow
CytologyInflammatory cellsMucinous epithelial cells

Q7. When do you intervene in a pancreatic pseudocyst?

A. Indications for intervention:
  1. Persistence beyond 6 weeks with symptoms
  2. Complications (infection, haemorrhage, rupture, biliary/bowel obstruction)
  3. Increasing size on follow-up
  4. Unable to exclude cystic neoplasm

Q8. What are the surgical drainage options for pseudocyst?

A.
  • Cystogastrostomy - posterior wall of stomach anastomosed to cyst; simplest
  • Roux-en-Y Cystojejunostomy - most versatile; ideal for any location; lowest recurrence (~5%)
  • Cystoduodenostomy - for cysts adherent to the duodenum
  • Recurrence rate for surgical drainage is ~5%, the lowest of all modalities (Bailey & Love)

Q9. What is the significance of elevated GGT in this patient?

A. GGT is elevated at 114 U/L (normal 12-64). This is consistent with:
  1. Chronic alcohol consumption - alcohol induces GGT microsomal enzyme induction; most sensitive marker of chronic alcohol use
  2. Biliary compression - pseudocyst compressing the bile duct/intrahepatic radicles raising ALP and GGT

Q10. Why is INR elevated (1.47) in this patient?

A. Chronic alcohol use causes hepatic parenchymal damage → reduced synthesis of vitamin K-dependent clotting factors (II, VII, IX, X) → prolonged PT/INR. This is important pre-operatively as it indicates risk of bleeding; requires Vitamin K supplementation or FFP before any surgery.

Q11. What is a "disconnected pancreatic duct syndrome"?

A. Occurs when a segment of the pancreatic duct is completely disrupted (usually after necrotizing pancreatitis). The isolated distal pancreatic remnant continues to secrete fluid that cannot drain into the duodenum → recurrent pseudocysts, pancreatic ascites, or pleural effusions. Requires surgical resection (distal pancreatectomy) or ERCP-guided stenting.

Q12. What are the complications of cystgastrostomy?

A.
  • Bleeding from the anastomosis
  • Gastric food debris entering the cyst (acting as a sump)
  • Recurrence (higher than Roux-en-Y)
  • Inadvertent anastomosis to a cystic neoplasm
  • Pancreaticocutaneous fistula (in external drainage)

Q13. What is the role of alcohol abstinence in management?

A. Alcohol is the primary etiological agent in this case. Abstinence:
  1. Prevents further episodes of acute-on-chronic pancreatitis
  2. Allows spontaneous resolution of acute fluid collections
  3. Reduces progression to exocrine and endocrine insufficiency
  4. Reduces risk of pseudocyst recurrence after drainage

Q14. What is the best analgesia for acute pancreatitis/pseudocyst pain?

A. IV Tramadol or NSAIDs (Diclofenac) are preferred. Morphine is traditionally avoided because it causes spasm of the sphincter of Oddi, potentially worsening pancreatic duct hypertension (though this is somewhat controversial in modern practice). Pethidine (meperidine) was historically preferred.

Q15. What is the expected outcome of this case?

A. Given:
  • Pseudocyst likely secondary to alcoholic pancreatitis (history consistent)
  • Patient now abstinent for 6 months
  • No overt complications (no fever, no jaundice, hemodynamically stable)
Conservative management with alcohol abstinence, analgesia, nutritional support, and close USG surveillance is the first approach. If the pseudocyst does not resolve within 6 weeks or complications arise, endoscopic EUS-guided cystogastrostomy or surgical Roux-en-Y cystojejunostomy is indicated.

  • Image (a): Visible bulging/distension in right hypochondrium / epigastrium - consistent with grossly enlarged gallbladder
  • Image (b): Palpable rounded mass in right hypochondrium outlined by marker - confirms palpable distended gallbladder
Examination findings:
  • Courvoisier's sign POSITIVE - palpable, non-tender, distended gallbladder in a jaundiced patient without pain
    • Courvoisier's Law: In obstructive jaundice, if the gallbladder is palpably enlarged and non-tender, the obstruction is unlikely to be due to gallstones (chronic inflammation scars the gallbladder) and is most likely malignant (Sleisenger & Fordtran)
  • Liver may be enlarged (hepatomegaly from biliary congestion)
  • No ascites initially

Key Interpretation:
  • Total bilirubin 14.8 mg/dl with predominantly direct (conjugated) fraction = obstructive / hepatic jaundice
  • Markedly raised ALP (250) and GGT (294) = biliary obstruction/cholestasis pattern
  • Normal amylase and lipase = pancreas not primarily involved (argues against pancreatic cancer)
  • Prolonged PT/INR = failure of fat-soluble vitamin K absorption (cholestasis → fat malabsorption → coagulopathy)
  • Leukocytosis with neutrophilia = mild inflammation / early cholangitis
  • Low albumin + anaemia = chronic malnutrition/malignancy

B. Imaging Investigations Required

USG Abdomen (First-line)

  • Dilated intrahepatic bile ducts (IHBRD) - shows level of obstruction
  • Dilated CBD > 8 mm
  • Distended gallbladder (Courvoisier's)
  • USG sensitivity for biliary dilation ~85-90%; exact cause determined in only 2/3 (Current Surgical Therapy 14e)

CECT Abdomen (Triple Phase with CT Angiography) - Investigation of Choice

  • Delineates level, cause, and extent of obstruction
  • Assesses vascular involvement (portal vein, hepatic artery) for resectability
  • Lymph node staging, liver metastases
  • Identifies: hilar mass (Klatskin tumour), GB wall thickening/mass, periductal enhancement

MRCP / MRI Abdomen

  • Best non-invasive imaging of biliary tree - sensitivity 95% (Current Surgical Therapy 14e)
  • Delineates Bismuth-Corlette classification for hilar cholangiocarcinoma
  • Differentiates benign from malignant strictures

ERCP / PTC

  • Therapeutic and diagnostic - biliary decompression (stent placement)
  • For tissue diagnosis via brushings / forceps biopsy
  • PTC (Percutaneous Transhepatic Cholangiography) - for proximal hilar obstructions

Tumour Markers

  • CA 19-9 - elevated in cholangiocarcinoma and pancreatic cancer
  • CEA - elevated in GI malignancies
  • CA 125 - if GB cancer suspected

MANAGEMENT

Step 1 - Pre-operative Preparation and Resuscitation

  1. IV access - wide bore cannulae
  2. IV fluids - Normal saline/dextrose saline; correct dehydration
  3. Vitamin K injection - 10 mg IM/IV for 3 days to correct coagulopathy (fat malabsorption → Vit K deficiency → prolonged PT) - target INR <1.5 before any invasive procedure (Current Surgical Therapy 14e: INR must be <1.7 for PBD)
  4. Treat pruritus - Cholestyramine 4g BD (binds bile salts in gut)
  5. Nutritional support - enteral nutrition; high protein, fat-restricted diet
  6. Correct anaemia - blood transfusion if Hb <8 pre-operatively
  7. Broad-spectrum antibiotics - cover gram-negative organisms; mandatory before any biliary instrumentation (prevents cholangitis)
  8. Monitor - urine output, LFTs, coagulation profile

Step 2 - Biliary Decompression (Pre-operative or Palliative)

  • ERCP + stenting - endoscopic biliary stent for distal CBD obstruction (plastic or self-expanding metal stent - SEMS)
  • PTC + external/internal biliary drainage (PBD) - for proximal hilar obstruction not accessible by ERCP
  • Pre-operative biliary drainage is indicated if: cholangitis, very high bilirubin (>15 mg/dl), coagulopathy, renal impairment

Step 3 - Definitive Surgical Management

For Cholangiocarcinoma (Hilar / Klatskin):

  • Bismuth-Corlette Classification guides resectability:
    • Type I/II: Hepaticojejunostomy (Roux-en-Y)
    • Type IIIa/b: Right/Left hepatectomy + biliary reconstruction
    • Type IV: Liver transplantation (in select centres) or palliative only
  • Excision of bile duct + Roux-en-Y hepaticojejunostomy

For Carcinoma Gallbladder with CBD involvement:

  • Extended cholecystectomy + en bloc resection of liver segments IVb+V + regional lymphadenectomy
  • CBD excision if involved + Roux-en-Y hepaticojejunostomy

Palliative Options (unresectable):

  • Biliary stenting (ERCP or PTC)
  • Surgical bypass - Roux-en-Y hepaticojejunostomy if endoscopic stenting fails
  • Chemotherapy: Gemcitabine + Cisplatin (standard for cholangiocarcinoma)
  • Photodynamic therapy (PDT) for biliary palliation

VIVA QUESTIONS AND ANSWERS


Q1. What is Courvoisier's Law? Is it applicable in this case?

A. Courvoisier's Law states: "In obstructive jaundice, if the gallbladder is palpably enlarged and non-tender, the cause of obstruction is unlikely to be gallstones." Rationale - chronic cholecystitis from gallstones causes fibrosis and scarring of the gallbladder wall, making it unable to distend. A malignant obstruction (cholangiocarcinoma, pancreatic head carcinoma) causes progressive obstruction of a previously normal gallbladder, which distends. In this case - YES, Courvoisier's sign is positive, supporting malignant aetiology. (Sleisenger & Fordtran)

Q2. Why is PT/INR prolonged in obstructive jaundice?

A. Bile is required for fat-soluble vitamin absorption. In complete biliary obstruction, bile does not reach the gut → fat malabsorption → Vitamin K deficiency → impaired synthesis of clotting factors II, VII, IX, X (Vitamin K-dependent) → prolonged PT/INR. Treatment: Vitamin K injection (10 mg IM/IV) for 3 days; if PT does not correct → hepatocellular failure (intrinsic liver disease).

Q3. What is the LFT pattern in obstructive vs. hepatocellular jaundice?

FeatureObstructiveHepatocellular
BilirubinDirect > IndirectBoth elevated
ALPMarkedly elevatedMildly elevated
GGTMarkedly elevatedElevated
AST/ALTMildly elevatedMarkedly elevated
PT correction with Vit KYesNo

Q4. What does "paintless progressive jaundice" suggest?

A. It classically suggests malignant biliary obstruction - cholangiocarcinoma, carcinoma head of pancreas, or ampullary carcinoma. Pain implies either: gallstone causing acute obstruction, or advanced tumour invading neural plexus. This patient has no pain + progressive deepening jaundice + 22 kg weight loss = malignancy until proven otherwise.

Q5. What is the Bismuth-Corlette Classification of hilar cholangiocarcinoma?

TypeLocation
IBelow hepatic duct confluence
IIInvolving confluence
IIIaRight hepatic duct
IIIbLeft hepatic duct
IVBoth right and left ducts

Q6. What is the investigation of choice for obstructive jaundice?

A. USG abdomen is the first-line (cheap, accessible, shows biliary dilation). MRCP is the best non-invasive imaging for biliary anatomy (sensitivity 95%). CECT abdomen with CT angiography is the investigation of choice for staging and surgical planning. ERCP/PTC are reserved for tissue diagnosis and biliary drainage.

Q7. What is the significance of clay-coloured stools and dark urine in this patient?

A. Clay-coloured (acholic) stools occur because bile pigments cannot reach the gut due to complete biliary obstruction → no stercobilinogen → pale stools. Dark urine occurs because conjugated bilirubin (water-soluble) spills into the urine (bilirubinuria) as plasma levels rise above the renal threshold. Together they confirm complete biliary obstruction - a surgical emergency requiring prompt decompression.

PAST HISTORY / FAMILY HISTORY / PERSONAL HISTORY

  • Not documented

GENERAL PHYSICAL EXAMINATION

ParameterExpected Findings
PulseTachycardia (HR >100 bpm)
BPElevated pulse pressure (increased systolic, decreased diastolic)
TemperatureLow-grade fever
WeightLow for height (BMI reduced)
HandsFine tremor, warm moist palms, onycholysis (Plummer's nails)
SkinWarm, moist, pretibial myxoedema may be present
EyesExophthalmos, lid lag, lid retraction (Dalrymple's sign), chemosis
NeckDiffuse goitre - soft, non-tender, moves with swallowing; thyroid bruit
HeartTachycardia, loud heart sounds, possible AF
Eye Signs in Graves' Disease:

  • Von Graefe's sign - lid lag on downward gaze
  • Stellwag's sign - infrequent blinking
  • Joffroy's sign - absent forehead wrinkling on upward gaze
  • Moebius sign - inability to converge

DIAGNOSIS

Primary Diagnosis:
Primary Thyrotoxicosis - Graves' Disease (Autoimmune diffuse toxic goitre with Graves' Ophthalmopathy)
Differential Diagnoses:
  • Toxic multinodular goitre (Plummer's disease)
  • Toxic adenoma
  • Thyroiditis (subacute, Hashimoto's)
  • Exogenous thyroid hormone intake

INVESTIGATIONS

A. Thyroid Function Tests - With Interpretation

ParameterValueNormalInterpretation
TSH<0.001 mIU/L0.4-5.0Undetectable - primary hyperthyroidism
T4 (Total)19.2 mcg/dl5-11Markedly elevated
FT44.4 ng/dl0.9-1.7Markedly elevated
T3 (Total)327 ng/dl100-200Markedly elevated
FT310.7 ng/dl2.3-4.1Markedly elevated (2.5x normal)
Interpretation: Suppressed TSH with markedly elevated T3, T4, FT3, FT4 = Primary Hyperthyroidism. The pattern is consistent with autonomous thyroid hormone production overriding the pituitary-thyroid axis.

B. Ultrasound Thyroid Findings

  • Diffuse enlargement of both lobes - consistent with Graves' diffuse goitre
  • Multiple nodules in both lobes - require evaluation (rule out concurrent malignancy in ~1-2%)
  • Thyroid Trans image: Both lobes enlarged flanking trachea

C. Doppler Findings

  • Markedly increased vascularity in both lobes - the classic "thyroid inferno" sign on colour Doppler
  • Pathognomonic of Graves' disease - reflects massively increased blood flow from TSH receptor antibody stimulation

D. Additional Investigations Required

InvestigationPurpose
TSH Receptor Antibodies (TRAb)Confirms Graves' disease; present in >95%
Anti-TPO, Anti-thyroglobulin antibodiesAutoimmune confirmation
Technetium-99m thyroid scanDiffuse uptake in Graves'; cold nodule = suspicious
ECGSinus tachycardia, AF assessment
ECHOThyrotoxic cardiomyopathy assessment
CBCAnaemia of thyrotoxicosis; leukopenia if on carbimazole
LFTBaseline before antithyroid drugs
Eye assessmentClinical activity score (CAS) for ophthalmopathy
FNACFor any cold nodule seen on USG

MANAGEMENT

Step 1 - Immediate Medical Control (Render Euthyroid Before Surgery)

A. Anti-Thyroid Drugs (ATDs) - Thionamides:
  • Carbimazole 30-40 mg/day (divided doses) OR Propylthiouracil (PTU) 300-400 mg/day
  • Mechanism: Inhibit thyroid peroxidase → block iodine organification → inhibit T3/T4 synthesis
  • PTU also blocks peripheral T4→T3 conversion (preferred in thyroid storm)
  • Duration until euthyroid: 4-6 weeks (monitor TFTs monthly)
B. Beta-Blocker:
  • Propranolol 40-80 mg TDS or Atenolol 50-100 mg OD
  • Controls adrenergic symptoms: tachycardia, tremor, anxiety, palpitations
  • Does NOT reduce thyroid hormone synthesis but blocks peripheral effects
C. Preoperative Lugol's Iodine (mandatory before surgery):
  • Lugol's solution (5% iodine + 10% KI, 5-7 drops TDS) OR Potassium Iodide drops
  • Given for 7-10 days immediately before surgery
  • Mechanism: Wolff-Chaikoff effect - high iodine suppresses iodine organification → reduces thyroid hormone synthesis + reduces thyroid vascularity and blood flow → less intraoperative bleeding (Current Surgical Therapy 14e)

Step 2 - Modality Selection (ATA Guidelines 2016)

SituationPreferred Treatment
Active Graves' Ophthalmopathy (as in this patient)Surgery or ATDs preferred; RAI worsens ophthalmopathy
Women planning pregnancy <6 monthsSurgery preferred
Large goitre >4 cmSurgery preferred
Suspected malignancySurgery
Persistent disease after ATDsSurgery or RAI
Elderly with comorbiditiesRAI or ATDs
(Current Surgical Therapy 14e, Table 2 - ATA 2016 Guidelines)
In this patient (25yr male, active ophthalmopathy, large goitre with nodules):
Total Thyroidectomy is the preferred treatment

Step 3 - Surgical Management

Operation: Total Thyroidectomy (ATA recommends total or near-total thyroidectomy for Graves')
  • Total thyroidectomy is associated with the lowest recurrence rate: 0.3% vs. 10% for subtotal thyroidectomy vs. 21% for RAI single dose (Current Surgical Therapy 14e)
Pre-operative checklist:
  1. Patient must be euthyroid (TFTs normal)
  2. Lugol's iodine for 7-10 days
  3. Propranolol continued until surgery
  4. INR, CBC, LFTs, serum calcium baseline
  5. Laryngoscopy to document vocal cord function (rule out pre-existing RLN palsy)
  6. DEXA scan - bone density assessment (thyrotoxicosis causes osteopenia)
Surgical Steps:
  1. Collar incision along Langer's lines
  2. Subplatysmal flaps raised
  3. Strap muscles separated
  4. Thyroid mobilized - individual ligation of superior and inferior thyroid vessels
  5. Identify and preserve: recurrent laryngeal nerve (RLN), parathyroid glands (x4)
  6. Total thyroidectomy specimen
  7. Drain placement
Specific risks in Graves' thyroidectomy (highest risk among all thyroid surgeries):
  • Hypoparathyroidism (permanent) - due to vascularity and adherence of glands
  • RLN injury - bilateral damage → respiratory distress
  • Thyroid storm (if inadequately prepared)
  • Neck haematoma (high vascularity - "thyroid inferno")
  • Hypothyroidism - expected; requires lifelong L-thyroxine

Step 4 - Post-operative Management

  1. Calcium and Vitamin D - monitor serum calcium every 6 hours post-op; supplement if low
  2. L-Thyroxine replacement - start at 1.6 mcg/kg/day (target TSH 0.5-2.0)
  3. Continue Propranolol - taper over 1-2 weeks post-op
  4. Ophthalmopathy management - IV methylprednisolone, selenium, orbital radiotherapy, decompression surgery (in conjunction with ophthalmology)

Step 5 - Graves' Ophthalmopathy Treatment

  • Selenium 200 mcg/day (mild active disease - EUGOGO guidelines)
  • IV Glucocorticoids (methylprednisolone) for moderate-severe active GO
  • Orbital decompression surgery for compressive optic neuropathy
  • Avoid RAI - worsens ophthalmopathy

VIVA QUESTIONS AND ANSWERS


Q1. What is the mechanism of Graves' disease?

A. Graves' disease is an autoimmune condition caused by TSH-receptor-stimulating antibodies (TRAb/TSHR-Ab). These IgG antibodies bind to and continuously stimulate TSH receptors on thyroid follicular cells → autonomous production of T3 and T4 → suppressed TSH from pituitary negative feedback → hyperthyroidism. The same antibodies stimulate fibroblasts in the orbit → glycosaminoglycan accumulation → orbital inflammation and proptosis (Graves' ophthalmopathy). (Cummings Otolaryngology)

Q2. Why is TSH undetectable (<0.001) in primary hyperthyroidism?

A. In primary hyperthyroidism, autonomous excess thyroid hormone production → markedly elevated T3/T4 → strong negative feedback on the pituitary → complete suppression of TSH secretion → TSH becomes undetectable. TSH is the most sensitive test for thyroid dysfunction - even mild hyperthyroidism suppresses TSH below normal range.

Q3. What is the purpose of Lugol's iodine before thyroidectomy for Graves' disease?

A. Lugol's solution (given for 7-10 days pre-op):
  1. Wolff-Chaikoff effect - high iodine load inhibits thyroid peroxidase → blocks thyroid hormone synthesis
  2. Reduces thyroid vascularity and blood flow - makes gland firmer, less vascular, easier to dissect
  3. Reduces intraoperative bleeding significantly
  4. Reduces risk of thyroid storm perioperatively

Q4. What is thyroid storm and how is it managed?

A. Thyroid storm (thyrotoxic crisis) is a life-threatening acute exacerbation of thyrotoxicosis precipitated by surgery, infection, trauma, or iodinated contrast.
Features: Hyperthermia >40°C, tachycardia >140 bpm, hypertension, agitation, confusion, vomiting, diarrhoea, high-output cardiac failure.
Management (Burch-Wartofsky Score >45 = treat):
  1. PTU 600 mg loading then 200-250 mg 4-hourly (blocks synthesis AND peripheral conversion)
  2. Iodine solution (at least 1 hour after PTU) - blocks hormone release
  3. IV Propranolol/Esmolol
  4. Hydrocortisone 100 mg 8-hourly (blocks T4→T3 conversion, treats relative adrenal insufficiency)
  5. Cooling measures, IV fluids, glucose
  6. ICU monitoring

Q5. What are the eye signs specific to Graves' disease vs. general thyrotoxicosis?

Signs in ALL thyrotoxicosisSigns specific to Graves' (infiltrative)
Lid retraction (Dalrymple's)Proptosis/Exophthalmos
Lid lag (Von Graefe's)Chemosis
StarePeriorbital oedema
Infrequent blinking (Stellwag's)Ophthalmoplegia
Optic nerve compression

Q6. Why is total thyroidectomy preferred over subtotal for Graves' disease?

A. As per ATA guidelines and evidence: total thyroidectomy has a recurrence rate of only 0.3% vs. 10% for subtotal thyroidectomy and 21% for single-dose RAI. Leaving any thyroid remnant in Graves' disease risks recurrence since circulating TRAb antibodies continue to stimulate remaining follicular cells. (Current Surgical Therapy 14e)

Q7. What are the complications of thyroidectomy for Graves' disease?

A. Graves' thyroidectomy carries the highest risk among all thyroid surgeries:
  1. Hypoparathyroidism (transient ~10%; permanent ~2-3%) - hypocalcaemia, tetany, Chvostek's/Trousseau's sign
  2. RLN injury - unilateral: hoarseness; bilateral: stridor, respiratory distress, re-intubation
  3. Thyroid storm - if inadequately prepared pre-op
  4. Neck haematoma - airway emergency; requires immediate wound opening
  5. Hypothyroidism - expected; requires lifelong L-thyroxine
  6. Wound infection, keloid scar (collar incision)
  7. Chyle leak (rare - left neck dissection)

Q8. What is the "thyroid inferno" sign on Doppler?

A. Markedly increased colour Doppler vascularity throughout both thyroid lobes - as seen in this patient's Doppler images. It represents massive hypervascularity from TSH-receptor antibody stimulation causing intense follicular activity and neoangiogenesis. It is highly characteristic of Graves' disease and helps distinguish it from other causes of hyperthyroidism (e.g., subacute thyroiditis where vascularity is reduced).

  • Buerger's test - angle at which pallor occurs; rubor on dependency
  • Capillary refill time >6 seconds (as noted in Long Case 7 equivalent)

Blood:

InvestigationPurpose
FBCAnaemia, polycythaemia
Blood glucose / HbA1cExclude DM
Lipid profileDyslipidaemia (major risk factor)
Serum creatinineRenal function (atherosclerosis affects renal arteries)
Coagulation profilePre-op, thrombophilia screen
ECG / EchoConcurrent CAD assessment

Imaging:

InvestigationPurpose
Duplex Doppler USGFirst-line - site and degree of stenosis/occlusion
CT Angiography (CTA)Gold standard for surgical planning - maps run-off vessels
MR Angiography (MRA)No contrast nephrotoxicity; good for distal vessels
Digital Subtraction Angiography (DSA)Invasive gold standard; simultaneous angioplasty possible

MANAGEMENT

Step 1 - Medical / Conservative (all patients):

  1. Absolute smoking cessation - single most important intervention
  2. Antiplatelet therapy - Aspirin 75-150 mg/day OR Clopidogrel 75 mg/day
  3. Statin therapy - Atorvastatin 40-80 mg/day (reduces cardiovascular events and may slow PAD progression)
  4. Control DM, HTN if present
  5. Cilostazol 100 mg BD (phosphodiesterase III inhibitor) - increases claudication distance
  6. Supervised exercise programme - improves collateral circulation
  7. Wound care - debridement, daily dressing

Step 2 - Revascularisation (Critical Limb Ischaemia):

Endovascular (preferred first-line for suitable anatomy):

  • Percutaneous Transluminal Angioplasty (PTA) ± stenting - for iliac, femoral stenosis
  • Balloon angioplasty with drug-eluting stent

Surgical Revascularisation:

  • Aorto-bifemoral bypass - for aortoiliac occlusion (Leriche syndrome)
  • Femoro-popliteal bypass - for SFA occlusion; autologous great saphenous vein preferred over synthetic graft
  • Femoro-distal bypass - using reversed saphenous vein graft to tibial/peroneal vessels
  • Endarterectomy - for localised disease

Step 3 - For Gangrene:

  • Dry gangrene of toes/foot - allow to auto-amputate OR
  • Amputation if wet/infected gangrene develops or revascularisation fails:
    • Toe amputation / Ray amputation - for limited digital gangrene
    • Transmetatarsal amputation
    • Below-knee amputation (BKA) - preferred over AKA; better rehabilitation
    • Above-knee amputation (AKA) - if BKA not feasible

VIVA QUESTIONS

Q1. What is intermittent claudication? What is its mechanism?

A. Cramping pain in muscles of the lower limb that appears on walking and is relieved by rest. Mechanism: Atherosclerotic narrowing of arteries → reduced blood flow → during exercise, oxygen demand exceeds supply → ischaemic metabolite accumulation (lactate, adenosine) → pain. Relieved by rest as demand drops and metabolites clear.

Q2. What is Fontaine Classification? Where does this patient fit?

A. Stage IV - critical limb ischaemia with gangrene. (See table above.)

Q3. What is the ABI and its significance?

A. Ankle-Brachial Index = ankle systolic BP / brachial systolic BP. Normal: 0.9-1.3. Claudication: 0.5-0.9. Rest pain: 0.3-0.5. Critical ischaemia / gangrene: <0.4. Values >1.3 suggest calcified incompressible vessels (DM). (Tintinalli's)

Q4. What are the differences between arterial and venous ulcers?

FeatureArterial UlcerVenous Ulcer
SiteTips of toes, pressure pointsGaiter area (medial malleolus)
PainVery painfulMild/moderate
EdgePunched outSloping
FloorPale, necroticSloughy, granulating
Surrounding skinShiny, cold, hair lossLipodermatosclerosis, pigmentation
PulseAbsentPresent
ABI<0.9Normal

Q5. What is dry vs. wet gangrene?

A. Dry: Sterile ischaemic necrosis; part becomes mummified; clear line of demarcation; non-spreading; no systemic toxaemia - seen in gradual arterial occlusion, atherosclerosis. Wet: Superadded infection + venous obstruction; oedematous, blistered, foul-smelling; no demarcation; spreading; severe systemic toxaemia - seen in DM, venous gangrene.

Q6. What is Leriche's syndrome?

A. Atherosclerotic occlusion of the aortic bifurcation causing: bilateral buttock/thigh claudication, impotence, and absent femoral pulses. Requires aorto-bifemoral bypass.

  • Clear line of demarcation (dry gangrene)
  • 6×4 cm oval ulcer on dorsum of left foot - erythematous margins, sloping edge, slough + necrotic tissue on floor - ischaemic ulcer
  • Skin: dry, hair loss, brittle nails - trophic changes
  • Fuchsig's test negative (left leg) - indicates non-filling of superficial veins, confirming arterial insufficiency

Palpation:

  • 2nd and 3rd toes: insensitive, no temperature sensation
  • Ulcer: painful, tender; base = subcutaneous tissue
  • Both lower limbs: cool on touch
  • CRT: 6 sec right, 8 sec left (severely impaired)
  • Peripheral pulses - Left: NO pulses below femoral artery; Right: Dorsalis pedis, anterior tibial, posterior tibial - feebly palpable

Auscultation: No bruit over either leg


DIAGNOSIS

Buerger's Disease (Thromboangiitis Obliterans - TAO) with Critical Limb Ischaemia Left foot: Dry gangrene of 2nd and 3rd toes + ischaemic ulcer, Fontaine Stage IV
Why Buerger's vs. Atherosclerosis:
  • Young age (40 years)
  • Heavy beedi smoker (beedis have higher nicotine content)
  • Distal small vessel involvement (digits first)
  • Progressive distal gangrene
  • No DM, HTN, dyslipidaemia

INVESTIGATIONS

Same as Long Case 4 plus:
  • Allen's test - assess upper limb involvement (TAO often affects upper limbs too)
  • Segmental limb pressures - confirms distal occlusion pattern
  • DSA / CTA - classic "corkscrew collaterals" around occlusion pathognomonic of Buerger's disease
  • Biopsy of affected vessel (rarely done) - shows acute segmental thrombosing vasculitis with preservation of internal elastic lamina
  • Hypercoagulability screen - ANA, ANCA (to exclude vasculitis mimics)

MANAGEMENT

  1. Absolute and permanent smoking cessation - MANDATORY; only intervention that halts progression
  2. Antiplatelet therapy - Aspirin/Clopidogrel
  3. Iloprost (prostacyclin analogue) IV infusion - improves tissue perfusion, reduces ulcer pain
  4. Calcium channel blockers (Nifedipine) - vasodilation
  5. Wound care - antiseptic dressings
  6. Sympathectomy (lumbar) - for rest pain palliation; increases skin blood flow; does NOT improve claudication
  7. Revascularisation - limited options due to distal small vessel involvement; bypass rarely feasible; omental transfer (rarely)
  8. Amputation - if gangrene extends, infection supervenes, or conservative management fails; aim for most distal level that heals

VIVA QUESTIONS

Q1. What is Buerger's disease?

A. Thromboangiitis Obliterans (TAO) - a non-atherosclerotic segmental inflammatory vasculitis affecting small and medium-sized arteries and veins of the distal extremities, strongly associated with tobacco use, predominantly in young males.

Q2. How do you distinguish TAO from atherosclerotic PAD?

FeatureTAO (Buerger's)Atherosclerotic PAD
Age<45 years>50 years
GenderYoung male, heavy smokerMiddle-aged, multiple risk factors
VesselsSmall/medium, distalLarge/medium, proximal
Lipids/DMNormalOften abnormal
AngiographyCorkscrew collateralsDiffuse atherosclerosis

Q3. What is Fuchsig's test?

A. The patient lies supine; examiner elevates the leg to 45° and compresses the veins at the ankle. On releasing, superficial veins should fill within 5-10 seconds. In Buerger's disease (arterial insufficiency), veins remain collapsed (negative test) as there is inadequate arterial inflow to fill the venous system.

Q4. What is the role of sympathectomy in PVD?

A. Lumbar sympathectomy (surgical or chemical/phenol) blocks sympathetic vasoconstriction to the skin vessels → increased skin blood flow. Useful for: rest pain, ischaemic ulcers, hyperhidrosis-related fissures. Does NOT significantly improve claudication (muscle vessels are not under sympathetic control during exercise). Can be done laparoscopically.

GENERAL PHYSICAL EXAMINATION

  • Moderately built and nourished; conscious, oriented
  • Pulse: 88/min; BP: 110/70 mmHg
  • PICCLE: Pallor/Icterus/Cyanosis/Clubbing/Lymphadenopathy/Edema - to be checked

LOCAL EXAMINATION - LEFT BREAST

From case sheet + photographs:

Inspection:

  • Asymmetry of breasts; left breast larger
  • Nipple retraction / deviation - left nipple
  • Skin changes: to note peau d'orange (dimpling), erythema, satellite nodules
  • Dilated veins over left breast

Palpation:

  • Surface smooth with well-defined margins
  • Occupies upper outer + inner quadrants + central quadrant (extending across)
  • Clinical photographs show: lump being measured (~8 cm), hard mass, nipple distortion
Left Axilla:
  • Single, 2×2 cm, firm, non-tender, mobile lymph node in left central group (level I)
Right breast and axilla: Normal

DIAGNOSIS

Primary Diagnosis:
Carcinoma of Left Breast - T3 N1 M0 (Stage IIIA)
TNM Staging:
  • T3: Tumour >5 cm (this is 8 cm)
  • N1: Mobile ipsilateral axillary lymph node involved
  • M0: No distant metastasis (to be confirmed with staging)
Most likely histology: Invasive Ductal Carcinoma (IDC) - most common (70-80%)

INVESTIGATIONS

Diagnostic Triple Assessment:

  1. Clinical Examination (done)
  2. Imaging - Mammography ± USG breast
  3. Histopathology - Core biopsy (preferred over FNAC)

Imaging:

InvestigationFindings expected
Bilateral MammogramIrregular spiculated mass with microcalcifications (BIRADS 5 = highly malignant)
USG BreastHypoechoic irregular mass with posterior acoustic shadowing; axillary node assessment
MRI BreastExtent of disease, multifocality, chest wall involvement

Histopathology:

  • Core needle biopsy (Trucut biopsy) - provides tissue diagnosis + receptor status
  • Receptor status (IHC):
    • ER (Oestrogen Receptor)
    • PR (Progesterone Receptor)
    • HER2/neu
    • Ki-67 (proliferation index)
  • Triple-negative (ER-/PR-/HER2-) = poorest prognosis

Staging Investigations:

InvestigationPurpose
CECT Chest + AbdomenLung, liver, adrenal metastases
Bone scan / PET-CTBone metastases
Serum LFTs, ALPLiver/bone involvement
CA 15-3 (tumour marker)Baseline, monitoring
FBC, coagulation profilePre-operative

MANAGEMENT

Step 1 - Multidisciplinary Team (MDT) approach

Step 2 - Neoadjuvant Chemotherapy (NAC)

  • For T3/T4 or N+ disease - recommended before surgery
  • Aims: downstage tumour → potentially allow breast conservation; assess chemosensitivity
  • Regimen: Anthracycline-based (AC) followed by Taxane (T): AC×4 → Paclitaxel×4
  • Response assessed by clinical exam + imaging after 3 cycles

Step 3 - Surgery

Option A: Modified Radical Mastectomy (MRM) - standard for this case

  • En bloc removal of: all breast tissue + nipple-areola complex + level I + II axillary lymph nodes + pectoralis minor fascia (Patey's operation)
  • Pectoralis major preserved (unlike Halsted radical)
  • Indication here: Large tumour (8 cm), central location, nipple involvement

Option B: Breast-Conserving Surgery (BCS/Lumpectomy)

  • Wide local excision + sentinel lymph node biopsy (SLNB) / axillary clearance
  • Requires: tumour <4-5 cm, adequate margins, patient preference, facility for radiotherapy
  • Not ideal here given 8 cm tumour and nipple distortion

Axillary Management:

  • SLNB - if axillary node clinically suspicious but small and mobile
  • Axillary lymph node dissection (ALND) Level I-III - for confirmed N1 disease

Step 4 - Adjuvant Therapy

TreatmentIndication
RadiotherapyAfter BCS (mandatory); after MRM if T3/T4 or ≥4 nodes positive
ChemotherapyHigh-risk features: node positive, triple negative, HER2+
Endocrine therapyER/PR positive: Tamoxifen (premenopausal) or Aromatase inhibitor (postmenopausal) ×5-10 years
Trastuzumab (Herceptin)HER2+ disease ×1 year

VIVA QUESTIONS

Q1. What is the triple assessment for a breast lump?

A. Clinical examination + Imaging (USG/mammogram) + Pathology (FNAC/core biopsy). If all three are concordant (benign or malignant), the diagnosis is reliable. Discordant results require repeat or excision biopsy.

Q2. What are the clinical signs suggesting malignancy in a breast lump?

A. Hard consistency, irregular border, fixity to skin/chest wall, skin changes (peau d'orange, dimpling, erythema), nipple retraction/deviation/discharge (bloody), axillary lymphadenopathy, satellite nodules.

Q3. What is peau d'orange? What causes it?

A. "Orange peel" skin - oedematous, pitted appearance over breast skin. Cause: lymphatic obstruction by tumour cells in the subdermal lymphatics → oedema of the skin; hair follicles remain tethered → pitting appearance.

Q4. What are the levels of axillary lymph nodes?

A. Classified in relation to pectoralis minor muscle:
  • Level I: Lateral to pectoralis minor (anterior, posterior, lateral groups)
  • Level II: Deep to pectoralis minor (central group, interpectoral/Rotter's nodes)
  • Level III: Medial to pectoralis minor (apical/infraclavicular) This patient has central group (Level I) involvement.

Q5. What is the difference between MRM and Halsted radical mastectomy?

A. Halsted removes pectoralis major and minor in addition to breast + axillary nodes (causes severe morbidity, arm oedema). MRM (Patey) preserves pectoralis major → better functional outcome; equivalent survival. MRM is the current standard.

Q6. What is the significance of ER/PR/HER2 status?

A. Determines adjuvant therapy selection:
  • ER/PR+: Endocrine therapy (Tamoxifen/AI) - 50% relative risk reduction in recurrence
  • HER2+: Trastuzumab (monoclonal antibody against HER2) + Pertuzumab
  • Triple negative (ER-/PR-/HER2-): Chemotherapy only; BRCA mutation testing; poorest prognosis


LONG CASE - INDIRECT INGUINAL HERNIA


PATIENT DETAILS

Age60 Years
GenderMale
AddressHampi

CHIEF COMPLAINTS

  • Swelling in right groin since 1 year

HISTORY OF PRESENTING COMPLAINTS

  • Single swelling, appeared above groin crease, then extended into scrotum
  • Initially small, gradually increasing in size
  • Increases in size with cough, straining, lifting weight
  • Disappears on lying down - reducible
  • No pain, no vomiting, no bowel changes

LOCAL EXAMINATION

  • Pyriform shaped swelling, 8×4 cm (or 5×6 cm in repeat exam)
  • Extending from above and medial to inguinal ligament down into scrotum
  • Cough impulse: PRESENT - expansile impulse on coughing
  • Penis in midline
  • Spontaneously reduces in supine position - reducible hernia
  • Cannot get above the swelling - confirms inguino-scrotal nature
  • Consistency: doughy, granular (omentum/bowel)
  • Testis palpable SEPARATELY from swelling - distinguishes from hydrocele
Special Tests:
  • Ring Occlusion Test: On occluding deep ring with thumb → swelling DID NOT appear on coughing = Indirect hernia (deep ring occlusion controls indirect hernia)
  • Zieman's test: Cough impulse at index finger (pointing at deep ring) - confirms indirect
  • Finger Invagination test: Cough impulse felt at TIP of finger - confirms indirect (direct = side of finger)

DIAGNOSIS

Right-sided Reducible Indirect Inguinoscrotal Hernia

INVESTIGATIONS

Pre-operative:

  • FBC, RFT, LFT, blood sugar, urine routine
  • ECG, CXR (anaesthetic fitness)
  • Coagulation profile
  • USG Groin - if diagnosis in doubt; differentiates hernia from hydrocele, lymph nodes
  • Spirometry if chronic cough (identify cause)

MANAGEMENT

Surgical - Standard Treatment: Inguinal Hernia Repair

Open Tension-Free Mesh Repair:

  • Lichtenstein's Repair - most common operation worldwide; polypropylene mesh placed in the inguinal canal over the posterior wall; tension-free (Bailey & Love; Current Surgical Therapy 14e)
  • Recurrence rate: ~1% (vs. 10-20% for tissue repairs)

Laparoscopic:

  • TAPP (Transabdominal Preperitoneal) - mesh placed laparoscopically
  • TEP (Totally Extraperitoneal) - avoids peritoneal cavity; preferred
  • Advantage: faster recovery, bilateral repair simultaneously

For Inguinoscrotal hernia:

  • Herniotomy (ligation of sac at deep ring) + herniorrhaphy/hernioplasty
  • Sac dissected from cord structures; high ligation at deep ring; mesh reinforcement

VIVA QUESTIONS

Q1. What is the difference between indirect and direct inguinal hernia?

FeatureIndirectDirect
AgeYoungOld
OriginThrough deep ring (lateral to inferior epigastric vessels)Through Hesselbach's triangle (medial to inferior epigastric)
Goes into scrotumYesRarely
Ring occlusion testControlledNot controlled
Invagination testTip of fingerSide of finger

Q2. What is Hesselbach's triangle?

A. Bounded by: inferior epigastric vessels (lateral), inguinal ligament (inferior), lateral border of rectus sheath (medial). Direct hernias protrude through this triangle.

Q3. What is the significance of "cannot get above the swelling"?

A. It confirms the swelling is descending from the inguinal canal (inguinoscrotal) rather than arising primarily in the scrotum (hydrocele/testicular mass). A swelling that you can "get above" is scrotal in origin.

Q4. What is Lichtenstein's repair?

A. Open tension-free mesh hernioplasty: polypropylene mesh is placed in the inguinal canal over the posterior wall (transversalis fascia), sutured to the inguinal ligament below and conjoint tendon above, with a slit for the spermatic cord. Recurrence <1%. Most common hernia repair in resource-rich countries. (Bailey & Love)

Q5. What are complications of inguinal hernia repair?

A. Immediate: haematoma, wound infection. Early: urinary retention, chest infection. Late: recurrence, chronic groin pain, mesh migration/infection, testicular atrophy, hydrocele, injury to ilioinguinal nerve (numbness).


SHORT CASE 2 - VARICOSE VEINS WITH VENOUS ULCER


PATIENT DETAILS

  • 37-year-old male, painter by profession
  • Non-healing, painful ulcer of right lower limb for 6 months
  • History of "swollen nerves" (tortuous dilated veins) and blackish discolouration of skin of lower 1/3rd of same limb

CLINICAL PHOTOGRAPH

The image shows:
  • Medial aspect of right ankle/gaiter area - classic location for venous ulcer
  • Lipodermatosclerosis - thickened, indurated, pigmented (haemosiderin deposition) skin in lower 1/3rd
  • Hyperpigmentation of gaiter area (inverted champagne bottle leg)
  • Tortuous dilated veins (varicosities) visible on leg

DIAGNOSIS

Primary Varicose Veins with Venous (Stasis) Ulcer - CEAP Class C6
CEAP Classification (Bailey & Love):
  • C0: No visible venous disease
  • C1: Telangiectasia/reticular veins
  • C2: Varicose veins
  • C3: Oedema
  • C4: Skin changes (pigmentation, lipodermatosclerosis)
  • C5: Healed ulcer
  • C6: Active venous ulcer ← this patient

INVESTIGATIONS

  • Duplex Doppler USG - confirms venous reflux; identifies incompetent perforators; assesses deep vein patency (rule out DVT)
  • Trendelenburg test - locates sapheno-femoral junction (SFJ) incompetence
  • Perthe's test - excludes deep vein thrombosis/obstruction
  • ABI - rule out arterial component before compression therapy (ABI must be >0.8)
  • Wound swab C&S

MANAGEMENT

Ulcer Care:

  1. Four-layer compression bandaging - mainstay of treatment; reduces venous hypertension; heals 70-80% ulcers
  2. Elevation of limb at rest
  3. Wound debridement + antiseptic dressings (silver-impregnated, alginate)
  4. Skin grafting for large chronic ulcers

Varicose Vein Treatment:

  1. High saphenous ligation + stripping (Trendelenburg operation) - ligation of SFJ + stripping of long saphenous vein
  2. Endovenous laser ablation (EVLA) / Radiofrequency ablation (RFA) - preferred in modern practice
  3. Foam sclerotherapy - injection of sclerosant (sodium tetradecyl sulphate) for smaller veins
  4. Subfascial endoscopic perforator surgery (SEPS) - for incompetent perforators near ulcer

VIVA QUESTIONS

Q1. What is the pathophysiology of venous ulcer?

A. Incompetent valves in superficial, perforating, or deep veins → venous reflux → venous hypertension in capillaries → fibrin deposition around capillaries (fibrin cuff theory) → reduced oxygen delivery to tissues → skin necrosis → ulceration. Also: leukocyte trapping → local inflammation.

Q2. Why is the gaiter area (medial malleolus) the classic site for venous ulcers?

A. The perforating veins connecting deep to superficial systems are most numerous and largest at the medial malleolus (Cockett's perforators). Incompetence here causes maximum venous hypertension at this specific region, predisposing to ulceration.

Q3. What differentiates venous from arterial ulcer? (See Long Case 4 comparison table above.)

Q4. What is lipodermatosclerosis?

A. Chronic inflammatory change of the subcutaneous fat and dermis in the gaiter area secondary to chronic venous hypertension → haemosiderin pigmentation, thickening, induration, and tapering of the limb above the ankle ("inverted champagne bottle" or "inverted bowling pin" leg).


SHORT CASE 5 - THYROGLOSSAL CYST


PATIENT DETAILS

  • 15-year-old female
  • Spherical cystic swelling in front of neck of size 1.5×1.5 cm
  • Moves with protrusion of tongue AND moves with deglutition

CLINICAL PHOTOGRAPHS

  • Two images showing a midline anterior neck swelling in a young female
  • Smooth, well-defined, cystic swelling in the midline at the level of hyoid bone/just below
  • No skin changes; skin freely mobile over swelling

DIAGNOSIS

Thyroglossal Duct Cyst
Pathognomonic feature: Movement with tongue protrusion (due to attachment of tract to the foramen caecum at base of tongue via hyoid bone)

INVESTIGATIONS

  • USG Neck - confirms cystic nature; confirms presence of normal thyroid inferiorly (mandatory before surgery - 1-2% of cases, the cyst IS the only functioning thyroid)
  • Thyroid function tests - rule out hypothyroidism
  • FNAC - if any doubt about diagnosis or firm component (rule out ectopic thyroid carcinoma - ~1% risk, papillary carcinoma most common)
  • CT scan - for large cysts or retrosternal extension

MANAGEMENT

Sistrunk's Operation - gold standard (Sabiston Textbook of Surgery)
Steps:
  1. Transverse incision over the cyst
  2. Complete excision of cyst
  3. Excision of central portion of hyoid bone (body)
  4. Excision of entire tract from hyoid to foramen caecum (base of tongue)
  • Rationale: Removing the hyoid body and complete tract prevents recurrence (recurrence if only cyst excised = 30-40%; with Sistrunk = <5%)

VIVA QUESTIONS

Q1. What is the embryological basis of thyroglossal cyst?

A. The thyroid gland develops from the floor of the pharynx (foramen caecum) at the junction of anterior 2/3 and posterior 1/3 of tongue. It descends to its final position via the thyroglossal duct, which passes through (not around) the body of hyoid bone. The duct normally obliterates by week 10. Persistence of any part → thyroglossal cyst anywhere along the tract (base of tongue to thyroid). (Sabiston Textbook of Surgery)

Q2. Why does a thyroglossal cyst move with tongue protrusion?

A. The persistent tract is attached to the foramen caecum at the base of the tongue. When the tongue protrudes, the hyoid bone elevates and the tongue base moves → the tract (and attached cyst) is pulled upward. This is pathognomonic and distinguishes it from other midline neck swellings.

Q3. What are the common sites of thyroglossal cyst?

A. 75% occur at or below the hyoid bone (subhyoid - most common); 20% at hyoid level; 5% suprahyoid/intralingual. Can also be retrosternal rarely.

Q4. Why must you confirm the presence of a normal thyroid before surgery?

A. In 1-2% of cases, the thyroglossal cyst contains the only functioning thyroid tissue (ectopic thyroid). Removing it without confirming a normal orthotopic thyroid would render the patient permanently hypothyroid. USG must confirm normal thyroid before Sistrunk's operation.

Q5. What is the most common malignancy arising in a thyroglossal cyst?

A. Papillary thyroid carcinoma (~1% of thyroglossal cysts). Treatment: Sistrunk's operation + total thyroidectomy + radioiodine ablation.


SHORT CASE 10 - SOLITARY THYROID NODULE (GOITRE)


PATIENT DETAILS

  • 32-year-old male, Tumkur
  • Swelling in front of neck for 6 years, gradually increasing
  • No pressure symptoms (no dysphagia, dyspnoea, stridor)
  • No hypo/hyperthyroidism symptoms

EXAMINATION

  • Single smooth-surfaced swelling; lower border visible
  • Left carotid pulse felt (pushing the carotid laterally)
  • Trachea shifted to the RIGHT - mass effect from left-sided/large right nodule
  • Moves with deglutition (attached to thyroid gland)
  • No other neck swellings
  • No lymphadenopathy documented

DIAGNOSIS

Solitary Nodule Thyroid (Solitary Thyroid Nodule - STN) Most likely: Benign colloid/adenomatous nodule OR follicular adenoma Must exclude: Carcinoma thyroid (40% risk of malignancy if radiation history (Schwartz's Surgery))

INVESTIGATIONS

Goal: Determine if benign or malignant.
InvestigationPurpose
TFTs (TSH, T3, T4)Assess thyroid function; if suppressed TSH → hot/autonomous nodule
USG Neck (Thyroid)Size, echogenicity, vascularity, margins, calcification, lymph nodes; TIRADS scoring
Technetium-99m scanHot (benign, autonomous) vs. Cold (10-20% risk malignancy) nodule
FNAC (USG-guided)Key investigation - Bethesda classification guides management
Chest X-rayTracheal deviation confirmation; retrosternal extension
CT neckFor large/retrosternal/compressive goitres (Pemberton's sign)
Serum calcitoninIf medullary thyroid carcinoma suspected
Vocal cord assessment (laryngoscopy)Pre-operative baseline; rule out RLN involvement

TIRADS (Thyroid Imaging Reporting and Data System):

  • TIRADS 1-2: Benign
  • TIRADS 3: Probably benign; follow-up
  • TIRADS 4-5: Suspicious/malignant; FNAC mandatory

Bethesda Classification (FNAC):

  • I: Non-diagnostic (repeat)
  • II: Benign (follow-up)
  • III: Atypia of undetermined significance (repeat/molecular testing)
  • IV: Follicular neoplasm (surgery)
  • V: Suspicious for malignancy (surgery)
  • VI: Malignant (surgery)

MANAGEMENT

Conservative (Bethesda II, TIRADS 1-2):

  • Regular USG follow-up every 6-12 months
  • Levothyroxine suppression (controversial; not routinely recommended)

Surgical (Indications):

  • FNAC Bethesda IV-VI (suspicious/malignant)
  • Tracheal deviation / compressive symptoms (as in this patient)
  • Size >4 cm
  • Rapid growth
  • Cosmetically unacceptable
Surgery:
  • Hemithyroidectomy (Lobectomy + isthmusectomy) - for indeterminate FNAC (Bethesda III/IV) or benign-appearing large nodule; allows definitive histology
  • Total thyroidectomy - if FNAC malignant, bilateral nodules, family history, or frozen section confirms malignancy intraoperatively
  • Frozen section - if FNAC inconclusive; extends to total thyroidectomy if malignancy confirmed

VIVA QUESTIONS

Q1. What features of a thyroid nodule raise suspicion for malignancy?

A.
  • Hard consistency, fixed, irregular
  • Rapid growth
  • Hoarseness (RLN invasion)
  • Dysphagia
  • Palpable cervical lymphadenopathy
  • History of neck irradiation
  • Family history of thyroid cancer or MEN
  • Male sex (higher risk in males)
  • Cold nodule on scan
  • TIRADS 4-5 on USG

Q2. What is Pemberton's sign?

A. Raising both arms above the head causes engorgement of neck veins, facial flushing, and stridor in patients with retrosternal goitre - due to thoracic inlet obstruction. (Schwartz's Principles of Surgery)

Q3. What are the types of thyroid carcinoma in order of frequency?

A.
  1. Papillary (~80%) - best prognosis; psammoma bodies; RET/PTC mutation; lymph node spread
  2. Follicular (~10%) - haematogenous spread (bone, lung); worse prognosis than papillary
  3. Medullary (~5%) - from parafollicular C-cells; elevated calcitonin; associated with MEN2
  4. Anaplastic (~1-2%) - worst prognosis; elderly; rapidly fatal

Q4. What is the management of a "cold nodule" on thyroid scan?

A. A cold (non-uptaking) nodule has 10-20% malignancy risk (vs. hot nodule ~1% malignancy). It requires USG-guided FNAC for cytological assessment → Bethesda classification → management as above.

Q5. What structures are at risk in thyroid surgery?

A.
  1. Recurrent laryngeal nerve (RLN) - runs in tracheoesophageal groove; unilateral injury = hoarseness; bilateral = stridor/respiratory distress
  2. Parathyroid glands (4 in number) - devascularisation → hypocalcaemia; tetany (Chvostek's/Trousseau's signs)
  3. External branch of superior laryngeal nerve - injury → loss of high-pitched phonation (singer's nerve)
  4. Superior/inferior thyroid vessels
  5. Thoracic duct (left side)
