PARTS OF HERNIA: Mouth (opening), Neck (narrowest part — most important), Body (sac), Contents (omentum most common, bowel, ovary) TYPES OF HERNIA: 1. INGUINAL HERNIA (most common) - Indirect inguinal hernia: through deep inguinal ring → inguinal canal → superficial ring. Congenital (patent processus vaginalis). More common. Young males. Can descend to scrotum. Controlled by deep ring pressure. - Direct inguinal hernia: through Hesselbach's triangle (medial to inferior epigastric vessels). Acquired. Middle-aged/elderly. Rarely descends to scrotum. NOT controlled by deep ring pressure. - Hasselbach's triangle: laterally = inferior epigastric vessels; medially = lateral border of rectus; inferiorly = inguinal ligament - Examination: cough impulse; can you get above it; transillumination (child); direct vs indirect - Differentiation: finger in deep ring → reduces indirect; direct: wide neck, does not enter scrotum, reducible spherical bulge 2. FEMORAL HERNIA - Through femoral canal (medial compartment of femoral sheath) - More common in women (wider pelvis) - Below and lateral to pubic tubercle (contrast: inguinal hernia above and medial to pubic tubercle) - HIGH risk of strangulation (narrow rigid neck = lacunar ligament) - Neck: femoral ring bounded anteriorly by inguinal ligament, posteriorly by pectineal ligament, medially by lacunar ligament, laterally by femoral vein - Treatment: Lotheissen (inguinal approach), McEvedy (extraperitoneal), Low approach (crural/Lockwood) 3. UMBILICAL HERNIA - True umbilical (infant): through umbilical ring; most resolve by age 2; surgery if persists >2 years - Para-umbilical (adult): through linea alba near umbilicus; women > men; obesity, multiple pregnancies; Mayo's repair (vest-over-pants) 4. INCISIONAL HERNIA - Through scar of previous operation - Causes: infection, obesity, malnutrition, steroids, poor technique, haematoma, chest infection - Treatment: mesh repair (tension-free) 5. EPIGASTRIC HERNIA: Through linea alba above umbilicus; small defect; usually contains extraperitoneal fat 6. SPIGELIAN HERNIA: Through spigelian fascia (at lateral border of rectus, below arcuate line); interparietal; often missed clinically 7. OBTURATOR HERNIA: Through obturator foramen; elderly thin women; Howship-Romberg sign (inner thigh pain on hip medial rotation = femoral nerve compression) 8. GLUTEAL/SCIATIC HERNIA: Through greater or lesser sciatic foramen 9. RICHTER'S HERNIA: Only PART of circumference of bowel wall in sac; can strangulate without obstruction; no cough impulse 10. LITTRE'S HERNIA: Contains Meckel's diverticulum in the sac 11. MAYDL'S HERNIA (Hernia-en-W): Two loops of bowel in sac; intermediate loop at risk of strangulation within abdomen 12. SLIDING HERNIA: Part of sac wall IS the viscus (sigmoid colon left, caecum right) COMPLICATIONS OF HERNIA: - Reducible → Irreducible → Obstructed → Strangulated - Strangulation: Arterial/venous occlusion; signs: acute pain, tense, tender, not reducible, overlying skin red; treatment = EMERGENCY surgery SURGICAL REPAIRS: - Herniotomy: sac ligation only (children) - Herniorrhaphy: sac + floor repair (tissue repair) - Hernioplasty: mesh reinforcement - Lichtenstein (tension-free mesh): Gold standard for inguinal hernia; polypropylene mesh over posterior wall; recurrence <1% - Shouldice repair: Running non-absorbable suture; 4-layer repair; best tissue repair <1% recurrence - Bassini repair: Historic; floor repair; higher recurrence - TEP (Totally Extraperitoneal): Laparoscopic; mesh in preperitoneal space; no entry into peritoneum - TAPP (Trans-Abdominal Pre-Peritoneal): Laparoscopic; through peritoneum; mesh placed preperitoneally NERVE INJURIES IN INGUINAL HERNIA SURGERY: - Ilioinguinal nerve: sensory loss inner thigh/scrotum (most commonly injured) - Iliohypogastric nerve: sensory loss above pubis - Genitofemoral nerve: loss of cremasteric reflex + inner thigh sensation - Lateral cutaneous nerve of thigh: lateral thigh numbness (meralgia paraesthetica) === VARICOSE VEIN === DEFINITION: Dilated, tortuous, elongated superficial veins with incompetent valves ANATOMY: Long saphenous vein (LSV) joins femoral vein at saphenofemoral junction (SFJ) 4 cm below and lateral to pubic tubercle. Short saphenous vein (SSV) joins popliteal vein at saphenopopliteal junction (SPJ). PATHOPHYSIOLOGY: Valve incompetence → venous hypertension → vein dilatation → further incompetence (cycle) CAUSES: - Primary: Congenital weakness of vein wall/valves; family history - Secondary: DVT (post-thrombotic), pregnancy, pelvic mass, AV fistula CEAP CLASSIFICATION: - C0: No visible/palpable signs - C1: Telangiectasia/reticular veins - C2: Varicose veins - C3: Oedema - C4: Skin changes (pigmentation, eczema, lipodermatosclerosis) - C5: Healed venous ulcer - C6: Active venous ulcer CLINICAL EXAMINATION: 1. Tourniquet test / Trendelenburg test: Elevate leg → empty veins → apply tourniquet at SFJ → ask to stand → if veins fill: incompetent perforators below tourniquet; if no filling then release: sudden filling = SFJ incompetence 2. Cough impulse test (Morrissey): Cough transmitted to SFJ area = saphenofemoral incompetence 3. Tap test: Tap vein — feel impulse transmitted distally = continuous column of blood = incompetent valves 4. Perthes test: Tourniquet applied to thigh while standing → exercise → if veins empty = deep vein patent; if more engorged = deep vein blocked INVESTIGATIONS: - Duplex Doppler USS: Gold standard; maps reflux; identifies incompetent SFJ/SPJ/perforators - Venogram: Rarely needed; contrast imaging COMPLICATIONS: 1. Haemorrhage (profuse; high pressure; treat by elevation + pressure) 2. Superficial thrombophlebitis 3. Venous ulceration (medial malleolus) 4. Pigmentation, lipodermatosclerosis, eczema 5. Phlebitis TREATMENT: Conservative: Compression stockings (Class II); avoid prolonged standing; elevation; weight loss Endovenous Laser Ablation (EVLA): Gold standard modern treatment; laser energy ablates GSV; minimal scarring; day case Radiofrequency Ablation (RFA): Similar to EVLA; thermal ablation Foam Sclerotherapy: Foam agent (STD/polidocanol) injected under USS guidance; obliterates vein; for C1-C3 Surgical (Trendelenburg + Stripping): - Trendelenburg operation: Flush ligation of SFJ with all 5-6 tributaries at saphenous opening; prevents recurrence from tributaries - Stripping of LSV: From groin to knee only (NOT below knee — sural nerve); avulsion of tributaries (multiple stab avulsions = phlebectomy) - Complications of surgery: Bruising/haematoma; DVT; nerve injury (sural nerve with SSV stripping; saphenous nerve with LSV stripping below knee); wound infection; recurrence (neovascularisation) === STOMA === DEFINITION: An artificial opening between a hollow viscus and the body surface TYPES: 1. COLOSTOMY: - End colostomy (Hartmann's operation): Single barrel; end of bowel; flush or slightly everted; semi-formed or formed stool - Loop colostomy: Defunctioning; two openings (proximal + distal); rod support - Transverse colostomy: Emergency defunctioning; large bowel obstruction - Sigmoid/descending (end): Post-APR; Hartmann's procedure - Site: Usually left iliac fossa - Output: Semi-formed/formed faeces 2. ILEOSTOMY: - End ileostomy: Post-proctocolectomy; permanent; right iliac fossa; SPOUTED (Brooke's ileostomy — 2-3 cm spout to protect skin from liquid effluent) - Loop ileostomy: Defunctioning; protects distal anastomosis (e.g., after LAR); right iliac fossa; easily reversed - Output: LIQUID (high output — 1-2 L/day); risk of dehydration/electrolyte imbalance (Na+ and water depletion) - Spout is essential (liquid stool burns skin without spout) 3. UROSTOMY (ILEAL CONDUIT): - Urinary diversion; loop of ileum; right iliac fossa; continuous urine output DIFFERENCES — Colostomy vs Ileostomy: - Colostomy: No spout (flush); formed stool; left iliac fossa; larger opening - Ileostomy: HAS SPOUT (Brooke's); liquid output; right iliac fossa; smaller opening; bag always wet COMPLICATIONS OF STOMA: Early: Ischaemia/necrosis, retraction, high output, paralytic ileus Late: Prolapse, parastomal hernia (most common late complication), stenosis, skin excoriation, recession, fistula PARASTOMAL HERNIA: Most common late complication; treat conservatively (support belt, resite stoma); surgery for obstruction/strangulation LOOP VS END STOMA: - Loop: Defunctioning; two barrels visible; rod support; easily reversible - End: Permanent or staged; single barrel; reversal requires laparotomy STOMA REVERSAL: - Loop ileostomy: Relatively simple; local reversal; within 3 months - Hartmann's reversal: Major laparotomy; high morbidity; 30-50% never reversed === X-RAY APPROACH IN SURGERY === APPROACH TO A SURGICAL X-RAY (SYSTEMATIC): 1. Name, date, projection 2. Technical quality (penetration, centering, rotation) 3. Systematic review: ERECT CHEST X-RAY: - Free gas under diaphragm = PNEUMOPERITONEUM = perforated viscus (most common: perforated peptic ulcer) - Both right and left hemidiaphragm; right higher - Minimum 1 mL gas detectable on erect CXR - Free gas appears as CRESCENT of air under right hemidiaphragm (right more clearly seen against liver) - Other causes: post-laparotomy (normal up to 7 days), perforated colon (diverticulitis, cancer), perforated appendix ERECT ABDOMINAL X-RAY: - Multiple fluid levels in small bowel = small bowel obstruction - Central, valvulae conniventes (complete folds), <3 cm diameter = small bowel - Peripheral, haustra (incomplete), >6 cm = large bowel obstruction - Caecal diameter >9 cm = impending caecal perforation (urgent surgery) SUPINE ABDOMINAL X-RAY: - Dilated loops: direction, position, calibre - Psoas shadow: absent = retroperitoneal pathology (haematoma, abscess) - Air in biliary tree (pneumobilia) = fistula, post-ERCP, emphysematous cholecystitis - Air in portal vein = bowel ischaemia (ominous sign) KEY X-RAY FINDINGS IN SURGERY: - Rigler's sign: Air on both sides of bowel wall = pneumoperitoneum - Football sign: Large central oval air collection = massive pneumoperitoneum - Cupola sign: Air under central diaphragm on supine CXR - Thumb-printing: Mucosal oedema = ischaemic colitis - Lead pipe colon: Loss of haustra = chronic ulcerative colitis - String sign of Kantor: Thread-like narrowing of terminal ileum = Crohn's disease (barium follow-through) TRAUMA X-RAYS (ATLS): - C-spine lateral (C1-C7 must be visible), AP chest, AP pelvis - FAST scan + CT if haemodynamically stable === SPECIMEN APPROACH IN SURGERY === APPROACH TO A SURGICAL SPECIMEN: 1. IDENTIFY the specimen: Name the organ/tissue 2. DESCRIBE systematically: a. Size and shape b. External surface (capsule, serosa, colour) c. Cut surface (if provided) d. Lesion description: site, size, shape, colour, margins, surface 3. DIAGNOSIS: State likely diagnosis 4. FURTHER DETAILS: a. Margins: clear/involved b. Lymph nodes if present c. Stage if malignant (pT, pN, pM) COMMON SURGICAL SPECIMENS: - Appendix: Inflamed, thickened, hyperaemic; faecalith may be present; periappendiceal fat changes - Gallbladder: Distended/contracted; stones (cholesterol=yellow faceted; pigment=black/brown); Courvoisier's = distended painless gallbladder - Stomach: Carcinoma — lesser curve/antrum; irregular ulcer with raised everted edges; linitis plastica = diffuse thickening - Colon: Carcinoma — annular (napkin-ring = LBO), polypoid, ulcerative; Dukes staging - Thyroid: Papillary Ca = irregular hard mass; follicular = encapsulated; anaplastic = stony hard fixed - Breast: Carcinoma = grey-white, hard, stellate margins, skin/nipple involvement; fibroadenoma = smooth, rubbery, encapsulated - Kidney: Renal cell carcinoma = golden yellow, necrosis, haemorrhage; Wilms = in child - Testis: Seminoma = homogeneous; Teratoma = heterogeneous with cysts/haemorrhage HISTOLOGY STAGING SYSTEMS: - DUKES: A=confined to wall; B=through wall; C1=local LN; C2=apical LN; D=distant mets - TNM: T (tumour), N (nodes), M (metastasis) - BRESLOW thickness (melanoma): <1 mm good prognosis BUILD INSTRUCTIONS: - Use ReportLab with A4, colour-coded chapters, tables, mnemonics, Q&A boxes - Chapter colours: Hernia=Navy, Varicose Vein=Teal, Stoma=Green, X-ray=Dark Red, Specimen=Purple - Include the varicose vein marking image if it exists at /home/daytona/workspace/surgery-viva2/varicose_marking.png - Add page numbers - Add a cover page with title "PG Surgery Viva — PDF 1: Hernia, Varicose Vein, Stoma, X-ray & Specimen" - Output file: /home/daytona/workspace/surgery-viva2/PDF1_Hernia_VV_Stoma_Xray.pdf Return: The exact file path and size of the created PDF.

You are building PDF 2 of a PG Surgery Viva series covering Operative Procedures 1-10. Create a detailed PDF using ReportLab at: /home/daytona/workspace/surgery-viva2/PDF2_Operations_1_10.pdf COVER: "PG Surgery Viva — PDF 2: Operative Procedures (Part A, Ops 1–10)" For EACH operation, include: - Definition/Purpose - Indications - Patient position + Anaesthesia - Incision - Steps (numbered, detailed) - Key anatomical structures/nerves/vessels at risk - Complications (early and late) - Viva Q&A (2-3 questions per operation) USE THIS EXACT CONTENT: === OP 1: SUPERFICIAL PAROTIDECTOMY === PURPOSE: Removal of superficial lobe of parotid gland (80% of gland, lateral to facial nerve) INDICATIONS: Pleomorphic adenoma (most common benign parotid tumour), Warthin's tumour, parotid carcinoma (confined to superficial lobe) POSITION: Supine, head turned away, sandbag under shoulder ANAESTHESIA: GA with south-facing RAE endotracheal tube INCISION: Modified Blair (pre-auricular + post-auricular + cervical = lazy S incision) KEY STEPS: 1. Modified Blair incision (pre-auricular → curve behind ear lobe → into neck along anterior border of SCM) 2. Raise skin flap (superficial musculoaponeurotic system = SMAS layer — stay superficial to SMAS) 3. Identify facial nerve — KEY STEP: a. Tragal pointer (cartilaginous pointer of tragus) — nerve is 1 cm deep and inferior to tip b. Posterior belly of digastric — nerve emerges at its upper border at stylomastoid foramen c. Tympanomastoid suture — nerve exits 6-8 mm deep to it 4. Follow facial nerve trunk → identify all 5 branches (Temporal, Zygomatic, Buccal, Marginal mandibular, Cervical — mnemonic: To Zanzibar By Motor Car) 5. Dissect superficial lobe off facial nerve branches (nerve stimulator used) 6. Remove specimen — include cuff of normal tissue if malignant 7. Haemostasis; place drain; close in layers NERVES AT RISK: - Facial nerve (VII): Most important — injury → facial palsy; marginal mandibular most vulnerable (deepest, smallest branch) - Great auricular nerve: Earlobe numbness (often deliberately sacrificed) - Auriculotemporal nerve: Frey's syndrome post-op (gustatory sweating = sweating over parotid area when eating) COMPLICATIONS: Early: Facial nerve palsy (most feared), haematoma, seroma, infection Late: Frey's syndrome (auriculotemporal nerve injury — parasympathetic fibres re-innervate sweat glands; Starch-iodine test = Minor's test; Rx: botulinum toxin), recurrence, salivary fistula, scar VIVA Q&A: Q: How do you identify facial nerve? A: Three landmarks — Tragal pointer (1 cm deep/inferior to tip), posterior belly of digastric, tympanomastoid suture Q: What is Frey's syndrome? A: Gustatory sweating after parotidectomy; auriculotemporal nerve parasympathetic fibres re-innervate sweat glands; Rx: botulinum toxin injection Q: Most vulnerable branch of facial nerve? A: Marginal mandibular branch (deep, small, little redundancy) === OP 2: SUBTOTAL THYROIDECTOMY === PURPOSE: Remove most of thyroid gland (leaving 2-3g remnant on each side — posterior capsule with parathyroids) INDICATIONS: Bilateral toxic multinodular goitre, Graves' disease (failed medical therapy), large compressive goitre NOTE: Total thyroidectomy preferred for thyroid carcinoma; subtotal avoids bilateral parathyroid damage POSITION: Supine, neck extended (sandbag under shoulders), head ring ANAESTHESIA: GA, endotracheal intubation INCISION: Kocher's collar incision — 2 cm above sternal notch; along Langer's lines; 6-8 cm long KEY STEPS: 1. Kocher's incision through skin → platysma → subplatysmal flaps raised (superior to thyroid cartilage; inferior to sternal notch) 2. Divide strap muscles vertically in midline (linea alba colli) — NOT divided transversely unless very large goitre 3. Mobilise thyroid lobe (rotate medially) 4. Ligate and divide SUPERIOR THYROID PEDICLE (superior thyroid artery + vein) CLOSE to upper pole (to protect external branch of superior laryngeal nerve) 5. Ligate INFERIOR THYROID ARTERY medially (where it enters parenchyma) NOT at its trunk (to protect RLN and blood supply to parathyroids) 6. Identify and PRESERVE all 4 parathyroid glands (posterior capsule) 7. IDENTIFY RECURRENT LARYNGEAL NERVE before ligation (runs in tracheoesophageal groove, enters larynx at inferior cornu of thyroid cartilage) 8. Divide Berry's ligament (suspensory ligament) — RLN is in close proximity here 9. Remove lobe leaving 2-3g posterior capsule bilaterally 10. Achieve haemostasis; close strap muscles; drain if needed; close platysma + skin NERVES AT RISK: - RLN: Unilateral = hoarse voice; Bilateral = stridor/respiratory failure (EMERGENCY) - External branch of SLN (EBSLN): Loss of high-pitched voice (singers affected most) - Parathyroids: Hypoparathyroidism → hypocalcaemia → tetany (Trousseau/Chvostek) COMPLICATIONS: Early: Haemorrhage (expand haematoma → airway compression → open wound immediately), RLN palsy, hypocalcaemia, thyroid storm Late: Hypothyroidism (requires thyroxine), recurrence, hypoparathyroidism VIVA Q&A: Q: Where is RLN most at risk? A: At Berry's ligament (suspensory ligament of Berry) where nerve may be dragged medially and at inferior thyroid artery ligation Q: How to protect parathyroids? A: Ligate inferior thyroid artery medially (not at trunk) to preserve parathyroid blood supply; leave posterior capsule Q: First action for haematoma post-thyroidectomy causing stridor? A: Open wound at bedside immediately — release haematoma to relieve airway compression === OP 3: THYROGLOSSAL CYST EXCISION (Sistrunk's Operation) === PURPOSE: Excision of thyroglossal cyst + tract + central portion of hyoid bone REASON FOR HYOID EXCISION: Thyroglossal duct is intimately related to hyoid bone; remnant tract above hyoid → recurrence; Sistrunk's operation reduces recurrence from 50% to <5% INDICATIONS: Thyroglossal cyst (congenital midline neck cyst arising from remnant of thyroglossal duct) EMBRYOLOGY: Thyroid descends from foramen caecum (base of tongue) along thyroglossal duct to final position; duct should obliterate; failure → thyroglossal cyst CLINICAL: Midline neck swelling; moves with swallowing AND with tongue protrusion (attached to hyoid via tract); most common 2-12 years age; 60% at or below hyoid POSITION: Supine, neck extended INCISION: Horizontal elliptical incision over cyst KEY STEPS (Sistrunk's Operation): 1. Elliptical incision to excise the skin punctum if there is a sinus 2. Dissect around cyst carefully (if ruptured → higher recurrence risk) 3. Trace tract superiorly to the hyoid bone 4. Remove the central BODY OF THE HYOID BONE (1 cm segment) with the tract passing through it 5. Continue dissection above hyoid through tongue musculature to the FORAMEN CAECUM (base of tongue) 6. Core of tongue musculature taken with the specimen up to foramen caecum 7. Close in layers; drain optional KEY POINT: If only cyst excised without hyoid → 50% recurrence; Sistrunk's → <5% recurrence COMPLICATIONS: Recurrence (if hyoid not removed), wound infection, fistula formation, damage to floor of mouth VIVA Q&A: Q: Why remove hyoid bone? A: Thyroglossal duct passes through/around hyoid; incomplete excision → recurrence; hyoid removal with core of tongue muscle reduces recurrence from 50% to <5% Q: How does thyroglossal cyst differ from thyroid swelling on examination? A: Thyroglossal cyst moves on BOTH swallowing AND tongue protrusion; thyroid moves only on swallowing Q: What is Sistrunk's operation? A: Excision of thyroglossal cyst + central body of hyoid bone + core of tongue musculature up to foramen caecum === OP 4: MODIFIED RADICAL MASTECTOMY (MRM / Patey's Operation) === PURPOSE: Removal of breast + axillary lymph nodes (levels I, II, III) + pectoralis minor; PRESERVING pectoralis major (contrast with Halsted's radical mastectomy which removes pectoralis major) INDICATIONS: Breast carcinoma not amenable to breast-conserving surgery (WLE); large tumour, multifocal disease, patient preference, BRCA carriers, local recurrence after WLE POSITION: Supine, arm abducted 90° on arm board ANAESTHESIA: GA INCISION: Stewart's transverse elliptical incision (encompasses nipple-areola complex + skin over tumour) KEY STEPS: 1. Transverse elliptical incision around nipple-areola complex and tumour with 2 cm skin margin 2. Raise skin flaps — between skin and subcutaneous fat (preserve perforators to skin; thin flaps if carcinoma near skin) 3. Divide pectoralis minor (Patey's modification) or retract (Auchincloss modification) to access level III nodes 4. Axillary dissection: a. Identify axillary vein (superior boundary) b. Clear levels I, II, III axillary nodes (lateral, posterior, medial to pectoralis minor) c. Preserve: Long thoracic nerve (of Bell) = serratus anterior → WINGED SCAPULA if damaged d. Preserve: Thoracodorsal nerve (latissimus dorsi) → weakness of shoulder adduction/extension if damaged e. Preserve: Intercostobrachial nerve (sensory → medial arm/axilla) — often divided → numbness 5. Remove breast tissue from pectoralis major fascia (pectoralis major preserved) 6. Two drains placed 7. Close skin (if tension, consider skin graft) NERVES AT RISK: - Long thoracic nerve (of Bell): Serratus anterior → WINGED SCAPULA (most important) - Thoracodorsal nerve: Latissimus dorsi → weakness of shoulder adduction - Intercostobrachial nerve: Sensory → arm numbness (commonly sacrificed) COMPLICATIONS: Early: Haematoma (most common), seroma (most common late early), flap ischaemia/necrosis, lymphoedema Late: Lymphoedema of arm (most significant late), frozen shoulder, phantom breast pain, chest wall recurrence VIVA Q&A: Q: Difference between Halsted's and Patey's (MRM)? A: Halsted's removes pectoralis major; Patey's (MRM) preserves pectoralis major; both clear all axillary nodes; Patey's has better functional outcome Q: Nerve causing winged scapula? A: Long thoracic nerve of Bell (C5,6,7) → serratus anterior; injury during axillary dissection Q: Most common early complication of MRM? A: Haematoma immediately; seroma (most common overall early-late) === OP 5: TRACHEOESOPHAGEAL FISTULA (TEF) REPAIR === PURPOSE: Surgical correction of congenital abnormal connection between trachea and oesophagus CLASSIFICATION (Gross/Vogt): - Type A (8%): Oesophageal atresia; no fistula - Type B (<1%): OA + proximal TEF - Type C (85%): OA + distal TEF (MOST COMMON) - Type D (<1%): OA + both fistulae - Type E/H (4%): TEF without atresia (H-type) PRESENTATION: 3 Cs: Choking, Coughing, Cyanosis on first feed. Polyhydramnios (in mother). Frothy bubbles at mouth. Cannot pass nasogastric tube. Associated VACTERL: Vertebral, Anorectal, Cardiac (VSD most common), TracheoEsophageal, Renal, Limb anomalies INVESTIGATIONS: Chest X-ray (coiled NGT in blind pouch = upper oesophageal pouch); echocardiogram (cardiac anomalies) POSITION: Left lateral decubitus ANAESTHESIA: GA; avoid bag-mask ventilation (distends stomach via fistula) INCISION: Right posterolateral thoracotomy through 4th intercostal space (extrapleural approach preferred) KEY STEPS: 1. Right posterolateral thoracotomy; extrapleural approach (reduces mediastinitis risk if anastomosis leaks) 2. Retract lung anteriorly 3. Identify azygos vein → divide (allows access to posterior mediastinum) 4. Identify fistula between trachea and oesophagus 5. Divide and ligate fistula at tracheal end (close to trachea to avoid tracheal stenosis) 6. Mobilise upper and lower oesophageal pouches 7. End-to-end oesophageal anastomosis (primary if gap <2 vertebral bodies) 8. If long gap: staged repair (gastrostomy feeding + delayed repair at 3 months) 9. Drain placed; chest closed COMPLICATIONS: Anastomotic leak (most common early), recurrent fistula, oesophageal stricture (most common late — dysphagia), gastro-oesophageal reflux, tracheomalacia VIVA Q&A: Q: Most common type of TEF? A: Type C (Gross) — oesophageal atresia with distal TEF (85%) Q: 3 Cs of TEF? A: Choking, Coughing, Cyanosis on first feed Q: Most common late complication? A: Oesophageal stricture (dysphagia; requires dilatation) === OP 6: RADICAL GASTRECTOMY WITH SPLENECTOMY === PURPOSE: Removal of whole stomach + spleen (and sometimes distal pancreas) for advanced proximal gastric carcinoma INDICATIONS: Gastric carcinoma involving gastric body/fundus/OGJ with splenic hilum involvement; D2 gastrectomy LYMPH NODE DISSECTION: - D1: Perigastric nodes (stations 1-6) - D2: D1 + nodes along named vessels (hepatic artery, left gastric, coeliac, splenic artery = stations 7-11) — STANDARD for curative resection in Asia - D3: Extended para-aortic JAPANESE CLASSIFICATION: Stomach divided into U (upper), M (middle), L (lower) thirds; determines extent of resection POSITION: Supine INCISION: Upper midline or rooftop (bilateral subcostal) KEY STEPS: 1. Laparotomy; assess resectability (liver mets, peritoneal seeding → palliation only) 2. Greater omentum detached (omentectomy — standard in gastric Ca) 3. Ligate short gastric vessels (allows splenectomy) 4. Divide gastrosplenic ligament, splenorenal ligament → splenectomy 5. Divide left gastric artery (station 7 nodes) 6. Ligate right gastric, right gastroepiploic, left gastroepiploic arteries 7. Divide oesophagus proximally (with 5 cm margin from tumour) 8. Divide duodenum distally (2-3 cm beyond pylorus) 9. D2 lymph node dissection 10. Reconstruction: Roux-en-Y oesophagojejunostomy (MOST COMMON after total gastrectomy) RECONSTRUCTION OPTIONS: Roux-en-Y (gold standard), jejunal interposition, Hunt-Lawrence pouch COMPLICATIONS: Anastomotic leak, duodenal stump blowout, pancreatic fistula, post-gastrectomy syndromes (dumping, loop syndrome), B12 deficiency (loss of intrinsic factor), iron deficiency anaemia, weight loss POST-GASTRECTOMY SYNDROMES: - Early dumping: 15-30 min after food; osmotic fluid shift to bowel; tachycardia, sweating, flushing - Late dumping (reactive hypoglycaemia): 2-3 hrs after food; insulin overshoot VIVA Q&A: Q: What is D2 gastrectomy? A: Removal of stomach + D1 perigastric nodes + nodes along named vessels (hepatic, left gastric, coeliac, splenic = stations 1-11) Q: Standard reconstruction after total gastrectomy? A: Roux-en-Y oesophagojejunostomy Q: What B12 complication occurs? A: Loss of intrinsic factor (secreted by parietal cells) → B12 malabsorption → megaloblastic anaemia; requires B12 injections lifelong === OP 7: TOTAL PROCTOCOLECTOMY === PURPOSE: Removal of entire colon + rectum + anus, with end ileostomy (Brooke) INDICATIONS: Familial adenomatous polyposis (FAP), ulcerative colitis (pancolitis, failed medical treatment, dysplasia, carcinoma), colorectal carcinoma involving entire colon VARIANTS: - Total proctocolectomy + end ileostomy (traditional; permanent stoma) - Restorative proctocolectomy (RPC) + ileal pouch-anal anastomosis (IPAA / J-pouch) = GOLD STANDARD for UC and FAP; avoids permanent stoma POSITION: Lithotomy Lloyd-Davies (combined abdominal + perineal approach) INCISION: Midline laparotomy KEY STEPS: 1. Mobilise colon — right colon first (medial-to-lateral dissection); preserve ureter, gonadal vessels 2. Divide at ileocaecal junction 3. Mobilise transverse, descending, sigmoid colon 4. Proctodissection: Total mesorectal excision (TME) — sharp dissection in holy plane between mesorectum and endopelvic fascia 5. Preserve pelvic autonomic nerves (hypogastric nerves, pelvic splanchnics → erectile function and bladder control) 6. Divide rectum at anorectal junction (or at dentate line for J-pouch) 7. Perineal phase: excise anus and close perineum (for total excision) 8. If J-pouch: Create ileal J-pouch (15 cm limbs) → anastomose to anal canal; defunctioning loop ileostomy for 8-12 weeks NERVES AT RISK: Hypogastric nerves (sympathetic → ejaculation/bladder neck), pelvic splanchnic nerves (S2-4, parasympathetic → erection), ureters COMPLICATIONS: Anastomotic leak, pelvic sepsis, sexual dysfunction (erectile dysfunction, retrograde ejaculation), urinary dysfunction, pouch complications (pouchitis = most common — treat with metronidazole/ciprofloxacin), pouch failure (10%) VIVA Q&A: Q: Indication for total proctocolectomy in UC? A: Failed medical treatment, dysplasia/carcinoma, toxic megacolon, perforation, haemorrhage Q: What is pouchitis? A: Inflammation of ileal J-pouch; most common late complication; presents with increased frequency, urgency, bleeding; treat with antibiotics (metronidazole, ciprofloxacin) Q: What is TME? A: Total mesorectal excision — sharp dissection in the avascular holy plane between mesorectum and endopelvic fascia; gold standard for rectal cancer; reduces local recurrence from 25% to <5% === OP 8: OESOPHAGOPLASTY (Oesophageal Replacement) === PURPOSE: Reconstruction of oesophagus using stomach, colon, or jejunum when oesophagus cannot be primarily repaired INDICATIONS: Long-gap oesophageal atresia (TEF repair where primary anastomosis impossible), corrosive ingestion (lye stricture), failed anti-reflux surgery, oesophageal resection for cancer CONDUIT OPTIONS: 1. GASTRIC PULL-UP (most common): Whole stomach mobilised → pulled up through posterior mediastinum or retrosternal route → anastomosed to cervical oesophagus. Blood supply: right gastroepiploic artery. Requires pyloroplasty (avoids delayed gastric emptying). Most widely used. 2. COLON INTERPOSITION: Left or right colon segment + its mesentery brought up. Used when stomach not available. Risk: graft ischaemia, leak. 3. JEJUNAL FREE FLAP: Jejunum with its mesenteric vessels as free flap; microvascular anastomosis to neck vessels. Used for short cervical defects. KEY POINTS: - Pyloroplasty required with gastric pull-up (vagus divided → gastroparesis) - Cervical anastomosis preferred (if leak → safer; forms fistula, not mediastinitis) COMPLICATIONS: Anastomotic leak (most feared), graft ischaemia/necrosis, stricture, dysphagia, aspiration, dumping syndrome VIVA Q&A: Q: Most common conduit for oesophageal replacement? A: Stomach (gastric pull-up); blood supply = right gastroepiploic artery; pyloroplasty required Q: Why is cervical anastomosis preferred? A: If anastomosis leaks → cervical fistula (manageable); thoracic leak → mediastinitis (life-threatening) === OP 9: OPEN CHOLECYSTECTOMY === PURPOSE: Removal of gallbladder via open laparotomy INDICATIONS: Failed laparoscopic cholecystectomy (conversion), acute cholecystitis with dense adhesions, suspected gallbladder carcinoma, cirrhosis with portal hypertension, emergency (perforation, empyema) POSITION: Supine; slight reverse Trendelenburg; left lateral tilt ANAESTHESIA: GA INCISION: Kocher's right subcostal incision (most common) OR right paramedian OR upper midline KEY STEPS: 1. Kocher's incision → enter peritoneum 2. Pack bowel away; retract liver superiorly 3. Identify Calot's triangle (hepatocystic triangle): cystic duct (medially), common hepatic duct (medially), liver (superiorly) 4. CRITICAL VIEW OF SAFETY (CVS): Dissect Calot's triangle — two and only two structures entering gallbladder = cystic duct + cystic artery 5. Clip and divide CYSTIC ARTERY (arising from right hepatic artery in 75%) 6. Clip and divide CYSTIC DUCT (confirm no CBD stones first; cholangiogram if indicated) 7. Dissect gallbladder off gallbladder bed (peritoneal reflection on either side) 8. Haemostasis of gallbladder bed 9. Drain if needed (infected/bile leak risk); close CALOT'S TRIANGLE: Bounded by — cystic duct (laterally), common hepatic duct (medially), liver (superiorly). Contents: cystic artery + node of Lund (Mascagni's node) HARTMANN'S POUCH: Infundibulum of gallbladder where stones commonly impact; may distort Calot's triangle → dangerous MIRIZZI SYNDROME: Stone in Hartmann's pouch → external compression of CBD → jaundice; must be identified pre-operatively COMPLICATIONS: Bile duct injury (MOST FEARED — 0.3-0.6%), bile leak, haemorrhage, infection, retained stone VIVA Q&A: Q: What is Calot's triangle? A: Bounded by cystic duct, common hepatic duct, and liver. Contains cystic artery and node of Lund. Q: What is Critical View of Safety (CVS)? A: Calot's triangle dissected clear with only two structures entering gallbladder base (cystic duct + cystic artery) before division. Prevents CBD injury. Q: Most feared complication? A: Bile duct injury (0.3-0.6%); can cause biliary stricture, biliary peritonitis, Bismuth classification for type. === OP 10: LAPAROSCOPIC CHOLECYSTECTOMY === PURPOSE: Minimally invasive removal of gallbladder INDICATIONS: Symptomatic gallstones (biliary colic, acute cholecystitis, mucocele), gallstone pancreatitis (semi-elective), cholecystitis GOLD STANDARD for uncomplicated gallstone disease POSITION: Supine → Reverse Trendelenburg + left tilt (bowel falls away) ANAESTHESIA: GA PORT PLACEMENT: - 10mm port: Umbilical (camera) - 10mm port: Epigastric (instruments) - 5mm port: Right anterior axillary line (retraction) - 5mm port: Right mid-clavicular line (retraction) PNEUMOPERITONEUM: CO2 insufflation to 12-15 mmHg via Veress needle (or Hassan open technique) KEY STEPS: 1. Veress needle insertion at umbilicus OR open Hassan technique (preferred if previous surgery) 2. CO2 pneumoperitoneum (12-15 mmHg) 3. 4-port placement (10+10+5+5) 4. Patient in reverse Trendelenburg + left tilt → bowel falls away from gallbladder 5. Retract gallbladder fundus superiorly (Rooftop grip) 6. Dissect Calot's triangle to achieve CRITICAL VIEW OF SAFETY 7. Clip and divide cystic artery (3 clips: 2 on patient side, 1 on specimen) 8. Clip and divide cystic duct (3 clips) 9. Dissect gallbladder from liver bed (electrocautery) 10. Extract gallbladder via umbilical port (may need extension if large stone) 11. Check for haemostasis; irrigate if bile spill 12. Remove ports under vision; close fascia at 10mm ports COMPLICATIONS: Port: Visceral injury (bowel/vessel at Veress), CO2 emphysema, port site hernia Biliary: CBD injury (0.3-0.6%), bile leak (cystic duct stump), retained CBD stone Conversion rate: ~5% → usually due to Calot's triangle adhesions SPECIFIC RISKS vs OPEN: Port site hernia, CO2 embolism (rare), gas-related complications VIVA Q&A: Q: What is the gold standard treatment for symptomatic gallstones? A: Laparoscopic cholecystectomy Q: What is Critical View of Safety in laparoscopic cholecystectomy? A: Calot's triangle dissected free with only 2 structures (cystic duct + cystic artery) entering gallbladder before clipping Q: When do you convert lap to open? A: Inability to identify CVS, severe bleeding, bile duct injury, dense adhesions making Calot's dissection unsafe BUILD INSTRUCTIONS: - Use ReportLab A4, professional colour-coded chapters - Operation number colour: alternate between Navy, Teal, Dark Green, Maroon, Deep Purple - Include for each op: Indications table, Steps numbered list, Nerves at risk table, Complications (early/late), Viva Q&A - Cover page, table of contents, page numbers - Output: /home/daytona/workspace/surgery-viva2/PDF2_Operations_1_10.pdf Return: The exact file path and file size.

Create a detailed PDF using ReportLab at: /home/daytona/workspace/surgery-viva2/PDF3_Operations_11_21.pdf COVER: "PG Surgery Viva — PDF 3: Operative Procedures (Part B, Ops 11–21)" For EACH operation, include: - Definition/Purpose - Indications - Patient position + Anaesthesia - Incision - Steps (numbered, detailed) - Key anatomical structures/nerves/vessels at risk - Complications (early and late) - Viva Q&A (2-3 questions per operation) USE THIS EXACT CONTENT: === OP 11: CHOLEDOCHODUODENOSTOMY === PURPOSE: Anastomosis between common bile duct (CBD) and first part of duodenum (bypass procedure) INDICATIONS: Large CBD stones not amenable to ERCP, benign CBD stricture (low), choledochal cyst (type I), recurrent pyogenic cholangitis PREREQUISITE: CBD must be dilated (>2 cm) — smaller duct = higher anastomotic leak risk POSITION: Supine INCISION: Right subcostal or upper midline KEY STEPS: 1. Expose CBD and first part of duodenum by Kocher manoeuvre (mobilise duodenum) 2. Longitudinal choledochotomy on CBD (1.5-2 cm) 3. Transverse duodenotomy of equal length 4. Side-to-side anastomosis using absorbable sutures (single layer) 5. Ensure no tension; stent may be placed 6. T-tube or drain placed; close KEY POINTS: - Side-to-side anastomosis (not end-to-side) - "Sump syndrome": food debris accumulates in distal CBD → infection (disadvantage) - Choledochojejunostomy (Roux-en-Y) preferred over choledochoduodenostomy to avoid sump syndrome COMPLICATIONS: Anastomotic leak, cholangitis (sump syndrome), stricture, fistula VIVA Q&A: Q: What is sump syndrome? A: Food debris accumulates in the distal (sump) end of CBD between the anastomosis and ampulla → cholangitis; seen with choledochoduodenostomy; prevented by Roux-en-Y choledochojejunostomy Q: Minimum CBD diameter for safe anastomosis? A: >2 cm (dilated CBD); narrow CBD → high risk of anastomotic failure Q: When is Roux-en-Y preferred over choledochoduodenostomy? A: Roux-en-Y has lower reflux/sump syndrome; preferred when duodenum scarred/obstructed or CBD not sufficiently dilated === OP 12: WHIPPLE'S PROCEDURE (PANCREATICODUODENECTOMY) === PURPOSE: Resection of head of pancreas + duodenum + distal bile duct + gallbladder + distal stomach (classic) or pylorus-preserving INDICATIONS: Carcinoma of head of pancreas, periampullary carcinoma (ampullary, bile duct, duodenal — BEST prognosis), chronic pancreatitis (intractable), IPMN RESECTABILITY CRITERIA (key viva): No distant metastasis; no superior mesenteric vein/portal vein invasion (or reconstructable); no encasement of SMA or coeliac artery POSITION: Supine INCISION: Upper midline or rooftop (bilateral subcostal) KEY STEPS — RESECTION PHASE: 1. Laparotomy; assess resectability (liver, peritoneum, SMA, SMV, portal vein) 2. Kocher manoeuvre (mobilise duodenum and pancreatic head off IVC and aorta) 3. Divide gastroduodenal artery (GDA) → establishes hepatic arterial flow; if hepatic pulse disappears = replaced right hepatic artery from SMA (must preserve) 4. Tunnel behind neck of pancreas over SMV/portal vein (no plane = vascular invasion = unresectable) 5. Divide stomach (classic Whipple) or preserve pylorus (PPPD = pylorus-preserving pancreaticoduodenectomy) 6. Divide bile duct (just below cystic duct entry) 7. Divide pancreas at neck (over SMV) 8. Divide duodenum/jejunum at ligament of Treitz 9. Detach specimen from SMA from right to left (uncinate process dissection) RECONSTRUCTION PHASE (Whipple's reconstruction — Child's method): 1. Pancreaticojejunostomy (or pancreaticogastrostomy) — highest anastomotic leak risk (5-20%) 2. Hepaticojejunostomy (bile duct to jejunum) 3. Gastrojejunostomy (or duodenojejunostomy if pylorus-preserving) Order: PJ → HJ → GJ (pancreas first, bile duct second, stomach/duodenum third — all on same Roux limb or separate loop) KEY VASCULAR ANATOMY: - GDA arises from common hepatic artery — divided during Whipple's - SMA = most important vessel; encasement = unresectable - Portal vein = formed by SMV + splenic vein; tunnelling behind pancreatic neck confirms resectability COMPLICATIONS: - Pancreatic fistula / POPF (Post-Operative Pancreatic Fistula) — most common and feared (5-20%) - Delayed gastric emptying (DGE) — most common complication overall - Bile leak, haemorrhage (sentinel bleed from GDA stump), wound infection, diabetes - Mortality: <5% in high-volume centres VIVA Q&A: Q: What determines resectability in pancreatic head carcinoma? A: No distant mets + no SMA/coeliac encasement + SMV/portal vein not invaded (or reconstructable) Q: What is the most common complication? A: Delayed gastric emptying (DGE); POPF (pancreatic fistula) most feared Q: What does dividing GDA confirm? A: Adequate hepatic arterial supply; if hepatic pulse disappears after GDA ligation → replaced right hepatic artery from SMA → must be preserved === OP 13: LOW ANTERIOR RESECTION (LAR) === PURPOSE: Resection of sigmoid colon + upper/mid rectum with primary colorectal anastomosis; SPHINCTER-PRESERVING procedure INDICATIONS: Rectal carcinoma in upper and mid-rectum (above 5-6 cm from anal verge); sigmoid carcinoma; diverticular disease; redundant sigmoid (volvulus) ONCOLOGICAL PRINCIPLE: Total Mesorectal Excision (TME) — sharp dissection in holy plane between mesorectum and endopelvic fascia → reduces local recurrence from 25% to <5% POSITION: Lithotomy Lloyd-Davies (combined abdominal + perineal access) INCISION: Lower midline laparotomy (or laparoscopic ports) KEY STEPS: 1. Identify and divide inferior mesenteric artery (IMA) at its origin (high tie) or just below left colic branch (low tie — preserves left colic for anastomosis blood supply) 2. Divide inferior mesenteric vein (IMV) at inferior border of pancreas for additional length 3. Mobilise sigmoid and left colon in medial-to-lateral dissection (preserve left ureter and gonadal vessels) 4. Enter avascular plane behind mesocolon (Toldt's fascia) 5. TME: Enter holy plane (Heald's plane) between mesorectum and endopelvic fascia; sharp dissection preserving pelvic autonomic nerves 6. Divide rectum 2 cm below tumour (using linear stapler transanally or open) with clear distal margin 7. Anastomosis: Colorectal anastomosis using circular stapler (double-staple technique most common); or hand-sewn 8. Test anastomosis (air test / saline test — fill pelvis with saline, insufflate rectum, check no bubbles) 9. Defunctioning loop ileostomy if anastomosis at risk (low anastomosis, pelvic contamination, steroids, malnutrition) NERVES AT RISK: - Hypogastric nerves: Retroperitoneal; injury → retrograde ejaculation / bladder dysfunction - Pelvic splanchnic nerves (nervi erigentes, S2-4): Injury → erectile dysfunction (males); urinary/sexual dysfunction - Ureters: Both ureters at risk during IMA ligation and lateral dissection COMPLICATIONS: Early: Anastomotic leak (5-15% — MOST IMPORTANT; worse with low anastomosis), haemorrhage, ureteric injury, pelvic sepsis Late: Anastomotic stricture, local recurrence, sexual/urinary dysfunction, adhesive obstruction LOW ANTERIOR RESECTION SYNDROME (LARS): Cluster of bowel dysfunction symptoms after LAR (urgency, frequency, fragmentation, incontinence); more common with very low anastomosis VIVA Q&A: Q: What is TME? A: Total mesorectal excision — sharp dissection in the holy/holy plane (Heald's plane) between mesorectum and endopelvic fascia; removes complete mesorectal envelope intact; reduces local recurrence from 25% to <5% Q: When do you defunction an LAR? A: Low anastomosis (<5 cm), pelvic contamination, steroids, malnutrition, poor blood supply, technical difficulty → loop ileostomy Q: Difference between LAR and APR? A: LAR: sphincter-preserving; anastomosis; tumour >5-6 cm from anal verge. APR: sphincter-removing; permanent colostomy; tumour <4-5 cm or invades sphincter complex === OP 14: ABDOMINOPERINEAL RESECTION (APR / Miles' Operation) === PURPOSE: Removal of rectum + anal canal + sphincter complex + sigmoid colon + permanent end sigmoid colostomy. No anastomosis. INDICATIONS: Low rectal carcinoma (<4-5 cm from anal verge) invading sphincter complex; anal carcinoma (failed chemoradiotherapy); benign (anal Crohn's, fistula-in-ano) POSITION: Lithotomy Lloyd-Davies (abdominal + perineal phases simultaneously or sequentially) INCISION: Lower midline + perineal elliptical incision KEY STEPS — ABDOMINAL PHASE: 1. High ligation of IMA; mobilise sigmoid and left colon 2. TME (total mesorectal excision) — same as LAR 3. Divide sigmoid colon at appropriate level 4. Preserve ureters, pelvic nerves (hypogastric, pelvic splanchnics) 5. Bring sigmoid out as permanent LEFT ILIAC FOSSA end colostomy (Hartmann's stump type) KEY STEPS — PERINEAL PHASE: 1. Elliptical incision around anus (with margin of skin) 2. Divide levator ani muscles, puborectalis, external anal sphincter 3. Dissect anteriorly carefully — RISK: posterior vaginal wall (female), urethral/prostatic injury (male) 4. Specimen removed from below (synchronous approach: two surgeons simultaneously) 5. Perineal wound closed primarily or with flap (large perineal defect) CYLINDRICAL APR (EXTRALEVATOR APR — ELAPE): More radical; removes levator ani with specimen; reduces positive circumferential resection margin for low rectal Ca; creates larger perineal defect (needs flap) COMPLICATIONS: Abdominal: As per TME surgery Perineal: Wound dehiscence/infection (most common — perineal wound), urethral injury, vaginal injury, perineal hernia (late) Long-term: Permanent colostomy, sexual dysfunction, urinary dysfunction, phantom rectum sensation VIVA Q&A: Q: What is Miles' operation? A: APR — abdominal + perineal resection of rectum + sphincters + permanent colostomy; described by Miles in 1908 Q: What is extralevator APR (ELAPE)? A: More radical APR removing levator ani en bloc; reduces positive CRM (circumferential resection margin) for very low rectal cancer; larger perineal defect needs flap reconstruction Q: Most common complication of perineal phase? A: Perineal wound infection/dehiscence (perineal wound has poor healing — contaminated field, poor blood supply) === OP 15: STANDARD APPENDICECTOMY (OPEN) === PURPOSE: Surgical removal of the appendix INDICATIONS: Acute appendicitis, appendix mass with failed conservative management, carcinoid of appendix (<2 cm = appendicectomy; >2 cm = right hemicolectomy), perforated appendicitis POSITION: Supine ANAESTHESIA: GA (spinal for high-risk patients) INCISION: Gridiron (McBurney's) incision — most common. Alternatively Lanz (transverse cosmetic incision) or right paramedian McBurney's Point: Junction of lateral 1/3 and medial 2/3 of line from ASIS to umbilicus KEY STEPS: 1. Gridiron incision at McBurney's point (splitting incision — each muscle layer split in direction of fibres) 2. External oblique (fibres run downward-medially) → split 3. Internal oblique + transversus (fibres run upward-medially) → split 4. Peritoneum opened; peritoneal fluid sent for culture 5. Identify caecum (taenia coli lead to appendix base) 6. Deliver appendix into wound 7. Divide mesoappendix (appendicular artery lies within — ligate separately) 8. APPENDIX BASE: Crush with clamp → tie with absorbable suture (ligature) at base; divide between ligature and clamp; INVERSION of stump (purse-string suture) — controversial but traditional 9. DO NOT invert if mucosal eversion present (risk of mucocele) 10. Irrigate peritoneal cavity if perforated 11. Close in layers (muscle by muscle; no sutures needed in muscle layers — they retract) APPENDICULAR ARTERY: Branch of ileocolic artery (from SMA); runs in free border of mesoappendix; must be ligated separately PATHOLOGICAL VARIANTS: - Retrocaecal (most common position = 74%): Must deliver carefully - Pelvic appendix: Mimics gynaecological pathology - Perforated: Peritoneal toilet; primary closure vs open; drain controversially placed COMPLICATIONS: Early: Wound infection (most common), ileus, haematoma, faecal fistula (ligature slips), bleeding Late: Adhesions, incisional hernia, stump appendicitis (if too much stump left) VIVA Q&A: Q: What is McBurney's point? A: Junction of lateral 1/3 and medial 2/3 of line from ASIS to umbilicus; site of maximum tenderness in appendicitis; site of Gridiron incision Q: Most common position of appendix? A: Retrocaecal (74%) Q: When should you perform right hemicolectomy instead of appendicectomy for carcinoid? A: Carcinoid >2 cm (higher risk of metastasis); <2 cm appendicectomy sufficient === OP 16: LAPAROSCOPIC APPENDICECTOMY === PURPOSE: Minimally invasive removal of appendix ADVANTAGES vs OPEN: Better visualisation (especially retrocaecal, pelvic, obese), less wound infection, faster recovery, diagnostic (can see full abdomen — useful in women with gynaecological DDx), less adhesions POSITION: Supine → Trendelenburg + right lateral tilt (bowel falls away from RIF) ANAESTHESIA: GA PORT PLACEMENT: - 10mm umbilical port (camera) - 10mm suprapubic or left iliac fossa port (stapler/clip applicator) - 5mm RIF or left flank port (retraction) KEY STEPS: 1. CO2 pneumoperitoneum (Veress or Hassan); 3 ports 2. Trendelenburg + right tilt 3. Identify caecum → trace taeniae coli to base of appendix 4. Mesoappendix: divide using bipolar/harmonic/ligasure → appendicular artery sealed 5. Apply 2-3 Endoloops (pre-formed endoscopic ligatures) at base; or Linear stapler across base 6. Divide appendix between loops 7. Extract via umbilical port in retrieval bag (prevents wound contamination) 8. Irrigate; check haemostasis; close ports COMPLICATIONS: As for open + CO2 complications + stump leak (if stapler misfires), port site hernia CONVERSION TO OPEN: Dense adhesions, perforation with faecal contamination, uncontrolled bleeding, inability to identify appendix VIVA Q&A: Q: Advantage of laparoscopic over open appendicectomy in women? A: Can inspect gynaecological structures (ovary, tube) — important DDx (ectopic pregnancy, ovarian cyst torsion, PID) Q: How is appendix base secured laparoscopically? A: Endoloops (2-3 pre-tied ligatures) OR endo-stapler (GIA) across base Q: When convert to open? A: Dense adhesions, uncontrolled bleeding, faecal peritonitis, inability to safely identify appendix base === OP 17: ORCHIDOPEXY FOR UNDESCENDED TESTIS (UDT) === PURPOSE: Surgical fixation of undescended testis into the scrotum INDICATIONS: Undescended testis (cryptorchidism) persisting after 6 months of age; recommend surgery at 6-12 months (BAPS guidelines); latest by 18 months to preserve fertility WHY EARLY? - Fertility: Spermatogonia lost after 2 years of heat exposure - Malignancy risk: Undescended testis has 10-40x increased risk of testicular malignancy (even after orchidopexy — risk reduced but not eliminated; orchidopexy allows easier self-examination) - Psychological: Body image POSITION: Supine ANAESTHESIA: GA + caudal block INCISION: Groin (inguinal) incision KEY STEPS (STANDARD ONE-STAGE ORCHIDOPEXY): 1. Inguinal incision (skin crease) 2. Identify and open external oblique aponeurosis through external ring 3. Identify testis in inguinal canal (or ring) 4. Carefully mobilise testis + cord — identify vas deferens + testicular vessels (do not injure) 5. Dissect hernial sac (patent processus vaginalis) from cord structures → herniotomy (ligate sac at deep ring) 6. Achieve adequate LENGTH by: a. Dividing gubernacular attachments b. Developing retroperitoneal space to gain vessel length 7. Create dartos pouch in scrotum (between skin and dartos muscle) 8. Pass testis through dartos pouch → fix with absorbable suture (to dartos — NOT scrotal skin — avoids testicular torsion) 9. Close inguinal canal FOWLER-STEPHENS ORCHIDOPEXY: For high-riding testis with short vessels; divide testicular vessels (relies on vasal/cremasteric collaterals); staged approach preferred (first stage — clip vessels; second stage at 6 months → mobilise) COMPLICATIONS: Testicular atrophy (most feared — due to vessel damage), failure to bring testis into scrotum, haematoma, wound infection, vas deferens injury, testicular torsion VIVA Q&A: Q: Why must orchidopexy be done early? A: Spermatogonia lost after 2 years of heat exposure; fertility preservation is key; also allows self-examination to detect malignancy Q: What is Fowler-Stephens orchidopexy? A: For high testis with short vessels; testicular artery divided in stage 1; vasal/cremasteric collaterals maintain blood supply; bring down in stage 2 at 6 months Q: 10x risk of what? A: Testicular malignancy (mainly seminoma); risk remains elevated even after orchidopexy but orchidopexy allows surveillance === OP 18: LAPAROSCOPIC GASTROJEJUNOSTOMY WITH VAGOTOMY === PURPOSE: Bypass of gastric outlet obstruction + reduce acid secretion INDICATIONS: Unresectable pyloric/duodenal obstruction (malignant or benign peptic — now rarely performed), peptic ulcer disease with GOO (now rare due to PPIs and H. pylori eradication) VAGOTOMY TYPES: 1. Truncal vagotomy: Division of both vagal trunks at oesophageal hiatus (destroys entire gastric + extragastric supply) 2. Selective vagotomy: Only gastric branches divided (preserves hepatic + coeliac branches) 3. Highly selective (proximal gastric / parietal cell vagotomy): Only acid-secreting parietal cell branches divided (preserves crow's foot to antrum → no drainage needed) GASTROJEJUNOSTOMY: Anastomosis between stomach and jejunum (bypasses obstructed pylorus/duodenum) KEY STEPS (LAPAROSCOPIC): 1. Port placement (standard 4-port) 2. Identify oesophageal hiatus → identify anterior and posterior vagal trunks (anterior = left vagus, posterior = right vagus) 3. Truncal vagotomy: Clip and divide both vagal trunks 4. Gastrojejunostomy: Identify ligament of Treitz → bring up first loop of jejunum (30 cm from Treitz) → anastomose to posterior surface of stomach (antrum) using linear stapler (posterior gastrojejunostomy = Hofmeister position) 5. Close enterotomy; check anastomosis NOTE: Truncal vagotomy always requires drainage procedure (gastrojejunostomy or pyloroplasty) due to gastroparesis COMPLICATIONS: Dumping (early/late), diarrhoea (vagotomy), anastomotic leak, ulceration at anastomosis (marginal/stomal ulcer), gastroparesis VIVA Q&A: Q: Why does truncal vagotomy require a drainage procedure? A: Truncal vagotomy also denervates pylorus → gastroparesis/gastric stasis → requires pyloroplasty or gastrojejunostomy for drainage Q: What is highly selective vagotomy? A: Division of only parietal cell secretory branches (crow's foot to antrum preserved); no drainage required; lowest complication rate; now rarely performed due to PPIs Q: What is marginal ulcer? A: Peptic ulcer occurring at gastrojejunostomy stoma (stomal ulcer); due to acid exposure on jejunal mucosa; treat with PPIs === OP 19: HELLER'S MYOTOMY === PURPOSE: Myotomy of lower oesophageal sphincter for achalasia cardia ACHALASIA: Failure of relaxation of LOS due to loss of Auerbach's (myenteric) plexus ganglion cells; increased resting LOS pressure; absent peristalsis; 'bird-beak' deformity on barium swallow INVESTIGATIONS: Barium swallow (bird-beak/rat-tail = achalasia), oesophageal manometry (gold standard — absent peristalsis + incomplete LOS relaxation), OGD (exclude malignant pseudoachalasia) POSITION: Supine (laparoscopic) ANAESTHESIA: GA KEY STEPS (LAPAROSCOPIC HELLER'S MYOTOMY + DORS/TOUPET FUNDOPLICATION): 1. 5-port laparoscopic approach; patient supine 2. Divide gastrohepatic ligament → expose oesophageal hiatus 3. Mobilise lower 6-8 cm oesophagus 4. Myotomy: Divide circular and longitudinal muscle fibres of lower oesophagus (6 cm) and continue 2-3 cm onto stomach (cardia) — must extend below GEJ to be effective 5. Ensure complete mucosal exposure (DO NOT enter mucosa) 6. Confirm complete myotomy — look for bleeding from mucosal vessels 7. ANTI-REFLUX PROCEDURE (MANDATORY): Dor partial anterior fundoplication (most common) OR Toupet posterior partial fundoplication → prevents GORD caused by myotomy 8. If mucosal perforation occurs → repair immediately with 4-0 Vicryl; confirm with air/methylene blue test COMPLICATIONS: Intraoperative: Oesophageal/gastric mucosal perforation (most feared — 5%; leads to leak if unrecognised) Early: Leak from unrecognised perforation, bleeding, dysphagia Late: GORD (if no anti-reflux procedure), recurrent dysphagia (incomplete myotomy or fibrosis), oesophageal carcinoma (long-standing achalasia — 3% lifetime risk) VIVA Q&A: Q: What is achalasia? A: Failure of LOS relaxation due to loss of Auerbach's plexus ganglion cells; absent peristalsis; bird-beak on barium swallow; manometry = gold standard Q: Why add fundoplication to Heller's myotomy? A: Myotomy destroys LOS mechanism → GORD; partial fundoplication (Dor/Toupet) prevents reflux while not obstructing the myotomy Q: What confirms complete myotomy? A: Extension of myotomy 2-3 cm below GEJ onto cardia; visible mucosal ballooning; bleeding from mucosal vessels === OP 20: IVOR LEWIS OESOPHAGECTOMY === PURPOSE: Resection of oesophageal carcinoma of middle/lower third using combined abdominal + right thoracic approach INDICATIONS: Carcinoma of middle and lower oesophagus (squamous cell or adenocarcinoma); Siewert type I/II OGJ tumours APPROACHES TO OESOPHAGECTOMY: 1. Ivor Lewis (Lewis-Tanner): Abdominal + right thoracotomy; intrathoracic anastomosis 2. McKeown (3-stage): Abdominal + right thoracic + left cervical; cervical anastomosis 3. Transhiatal (Orringer): Abdominal + cervical; no thoracotomy; blunt mediastinal dissection 4. Left thoracoabdominal: Single left chest incision IVOR LEWIS SPECIFIC: POSITION: Supine (abdominal phase) → Left lateral decubitus (thoracic phase) ANAESTHESIA: GA; double-lumen endotracheal tube (one lung ventilation for thoracic phase) KEY STEPS — ABDOMINAL PHASE: 1. Upper midline laparotomy 2. Gastric mobilisation: divide short gastrics, left gastroepiploic, left gastric artery, lesser omentum; PRESERVE right gastroepiploic artery (main blood supply to gastric conduit) 3. Kocher manoeuvre 4. Create gastric tube/conduit (using linear stapler along greater curve; 4-5 cm wide tube) 5. Pyloroplasty or pyloromyotomy (prevent delayed gastric emptying due to vagotomy) 6. Feeding jejunostomy placed 7. Mobilise oesophagus at hiatus; lymphadenectomy KEY STEPS — THORACIC PHASE (right posterolateral thoracotomy, 4th-5th ICS): 1. Single lung ventilation; retract right lung anteriorly 2. Divide azygos vein 3. Mobilise oesophagus with two-field lymphadenectomy (mediastinal + upper abdominal nodes) 4. Divide oesophagus above tumour with adequate (5 cm) margin 5. Deliver gastric conduit through diaphragmatic hiatus into right chest 6. Intrathoracic anastomosis (oesophagogastrostomy) — circular stapled or hand-sewn 7. Drain right chest; close thoracotomy; re-expand lung BLOOD SUPPLY TO CONDUIT: Right gastroepiploic artery (preserved during abdominal phase); fundus = watershed → most vulnerable to ischaemia COMPLICATIONS: Anastomotic leak: Most serious early complication; intrathoracic leak → mediastinitis → high mortality; cervical leak safer Conduit ischaemia/necrosis: Life-threatening; occurs at fundal tip Chylothorax: Injury to thoracic duct; milky pleural fluid; treat conservatively → re-explore if >1L/day Recurrent laryngeal nerve injury: Right RLN during thoracic dissection (left in cervical approach) Delayed gastric emptying, stricture, GORD, dumping, respiratory complications VIVA Q&A: Q: Blood supply to gastric conduit in Ivor Lewis? A: Right gastroepiploic artery (must be preserved); fundus is watershed and most vulnerable Q: What is a chylothorax? A: Lymph leak from thoracic duct injury during oesophagectomy; milky pleural fluid; treat conservatively (nil by mouth, TPN, octreotide); re-explore and ligate duct if >1L/day persists >5 days Q: Ivor Lewis vs McKeown vs Transhiatal? A: Ivor Lewis = intrathoracic anastomosis (leak more dangerous); McKeown = cervical anastomosis (safer leak); Transhiatal = no thoracotomy (good for poor respiratory reserve) === OP 21: RADICAL NEPHRECTOMY === PURPOSE: Removal of entire kidney + perirenal fat + Gerota's fascia + ipsilateral adrenal gland + regional lymph nodes INDICATIONS: Renal cell carcinoma (RCC), transitional cell carcinoma of renal pelvis, Wilms' tumour (in children — nephroblastoma), non-functioning kidney with chronic infection, trauma STAGING: TNM; T1 (<7 cm, confined); T2 (>7 cm, confined); T3 (renal vein/IVC/adrenal); T4 (Gerota's fascia breach); N1 (nodes); M1 (mets) CHARACTERISTIC OF RCC: "Rich vascular tumour"; von Hippel-Lindau gene (VHL) on chromosome 3p; golden yellow with necrosis/haemorrhage; paraneoplastic syndromes (Stauffer syndrome = abnormal LFTs without mets); IVC extension in 5-10% POSITION: Lateral decubitus (flank approach) OR supine (anterior transperitoneal) INCISION: Flank incision (11th/12th rib), loin incision, or midline/chevron (open); laparoscopic (4-5 ports) KEY STEPS (OPEN FLANK): 1. Flank incision; 11th or 12th rib may be resected for access 2. Divide latissimus dorsi, external/internal oblique, transversus abdominis 3. Enter Gerota's fascia — mobilise kidney WITHIN Gerota's fascia (en bloc with perirenal fat) 4. EARLY LIGATION OF RENAL ARTERY (before vein) — reduces bleeding, reduces tumour embolism 5. Ligation of renal vein 6. Clip and divide ureter in upper third 7. Dissect adrenal gland (separate from main specimen or en bloc if T3b/adrenal involvement) 8. Regional lymph node dissection 9. IF IVC EXTENSION: extend exposure; may require cardiopulmonary bypass for level III/IV thrombus IVC THROMBUS LEVELS: - Level I: Below hepatic veins (30% of IVC cases) - Level II: To hepatic veins - Level III: Above hepatic veins (infrahepatic/retrohepatic) - Level IV: Intracardiac (rare; requires CPB) LAPAROSCOPIC RADICAL NEPHRECTOMY: Standard for T1-T2; transperitoneal or retroperitoneoscopic; faster recovery; extract specimen in bag via extended port PARTIAL NEPHRECTOMY (NEPHRON-SPARING): For T1a (<4 cm); solitary kidney; bilateral RCC; preserves renal function COMPLICATIONS: Intraoperative: IVC/renal vein/aorta injury, splenic/pancreatic injury (left side), liver injury (right side), bowel injury, pneumothorax (if rib resected) Early: Haemorrhage, adrenal insufficiency (bilateral), ileus, wound infection Late: Renal failure (compensatory hypertrophy of remaining kidney usually adequate), tumour recurrence VIVA Q&A: Q: Why ligate renal artery before vein? A: Prevents backflow and engorgement of kidney; reduces intraoperative blood loss and risk of tumour embolism Q: Characteristic gross appearance of RCC? A: Golden yellow with areas of necrosis and haemorrhage; highly vascular; may have IVC extension Q: What is Stauffer syndrome? A: Paraneoplastic hepatic dysfunction (elevated LFTs) without hepatic metastasis; associated with RCC; resolves after nephrectomy BUILD INSTRUCTIONS: - Use ReportLab A4, professional formatting - Each operation gets its own colour-coded section header - Include: Indication table, Numbered steps, Nerves/vessels at risk table, Complications (early+late), Viva Q&A boxes - Cover page, Table of Contents, Page numbers - Output: /home/daytona/workspace/surgery-viva2/PDF3_Operations_11_21.pdf Return: Exact file path and file size.
