Now I have enough content from the textbooks. Let me compile a comprehensive, easy-to-study answer covering all the topics requested.
π₯ Surgery - Complete Notes (Easy Way!)
Sources: Bailey & Love's Short Practice of Surgery 28e, Robbins Pathology, Yamada's Gastroenterology, Cummings Otolaryngology, Scott-Brown's ENT Surgery
1. PERITONITIS - Types & Stages
Definition: Inflammation of the peritoneum (the lining of the abdominal cavity).
Types:
| Type | Description |
|---|---|
| Primary (Spontaneous) | No obvious intra-abdominal source. E.g. SBP (Spontaneous Bacterial Peritonitis) in cirrhosis patients - organisms reach peritoneum via blood |
| Secondary | Due to perforation/rupture of an intra-abdominal organ (perforated peptic ulcer, appendix, bowel). Most common surgical type |
| Tertiary | Persistent/recurrent after treatment of secondary peritonitis - in immunocompromised patients |
Sub-types by exudate:
- Acute Suppurative Peritonitis - pus formation (see section 14 below)
- Chemical/Biliary peritonitis - bile leak
- Faecal peritonitis - bowel perforation
- Tuberculous peritonitis - chronic, fibrous adhesions
Stages (Hamburg Classification):
| Stage | Description |
|---|---|
| I | Local peritonitis (limited to area of origin) |
| II | Diffuse peritonitis (involves entire peritoneal cavity) |
| III | Peritonitis + organ dysfunction (MODS - septic shock) |
Key Signs:
- Board-like rigidity (guarding/rigidity) - most important
- Rebound tenderness (Blumberg's sign)
- Silent abdomen (absent bowel sounds)
- Fever, tachycardia, dehydration
2. ACHALASIA CARDIA - Signs
Definition: Motility disorder of the distal oesophagus with failure of the lower oesophageal sphincter (LOS) to relax, causing functional obstruction.
Key Signs & Features:
| Feature | Detail |
|---|---|
| Dysphagia | Starts with solids, progresses to liquids |
| Regurgitation | Especially at night (undigested food, no bile) |
| Weight loss | Due to inadequate nutrition |
| Chest pain | Occurs in some patients |
| Bad breath (halitosis) | From stagnant food in oesophagus |
| Respiratory symptoms | From aspiration |
Investigations:
- Barium swallow - Classic "Bird's beak/Rat-tail" appearance at lower end + massively dilated oesophagus above
- Manometry - High resting LOS pressure + failure to relax + absent peristalsis
- Endoscopy - Baggy dilated oesophagus, food debris
Treatment:
- Medical: Calcium channel blockers, nitrates, anticholinergics (poor results)
- Endoscopic: Pneumatic balloon dilatation, Botox injection
- Surgical: Heller's cardiomyotomy + partial fundoplication (laparoscopic/POEM - per-oral endoscopic myotomy)
3. PLUMMER-VINSON SYNDROME (Patterson-Kelly Syndrome)
Simple memory: PVS = Post-cricoid web + Dysphagia + Iron deficiency anaemia + Female (middle-aged)
Features:
- Post-cricoid web (mucosal web in upper oesophagus/hypopharynx)
- Iron deficiency anaemia (microcytic hypochromic)
- Dysphagia (for solids initially)
- Koilonychia (spoon-shaped nails)
- Glossitis, Angular stomatitis
- Affects: Middle-aged women predominantly
Importance:
- Pre-malignant - risk of post-cricoid/hypopharyngeal carcinoma
- Treatment: Iron supplementation + dilatation of web
4. GASTRIC OUTLET OBSTRUCTION (GOO) - Signs
Causes: Peptic ulcer disease (benign) or gastric cancer (malignant) - should be considered malignant until proven otherwise.
Classic Signs:
| Sign | Detail |
|---|---|
| Succussion splash | Audible splash on shaking abdomen (fluid in distended stomach) - the most classic sign |
| Visible gastric peristalsis | Wave movement visible on abdominal wall (stomach trying to push against obstruction) |
| Projectile vomiting | Non-bilious, contains undigested food |
| Epigastric distension | Visibly distended stomach |
| Dehydration | From repeated vomiting |
Metabolic Consequence (BOARDS FAVOURITE):
Hypochloraemic Hypokalaemic Metabolic Alkalosis
- Vomiting loses HCl β low chloride β alkalosis
- Kidneys try to compensate β excrete K+ β hypokalaemia
- Urine becomes paradoxically acidic (aciduria)
- Can lead to tetany (from lowered ionised calcium due to alkalosis)
Management:
- Correct metabolic abnormalities: IV isotonic saline + KCl
- Large-bore nasogastric tube/orogastric lavage
- Endoscopy + biopsy (exclude malignancy)
- Endoscopic dilatation (benign), surgery (malignant or failed medical)
5. LYMPHANGITIS - Types & Stages
Definition: Inflammation of lymphatic vessels due to bacterial infection - appears as painful red streaks tracking along lymphatics from the infection source. - Bailey & Love's, p.78
Types:
| Type | Description |
|---|---|
| Acute Lymphangitis | Bacterial (Strep pyogenes, Staph aureus) - red streaks from wound, tender lymph nodes. Can lead to bacteraemia/sepsis if untreated |
| Chronic Lymphangitis | Repeated episodes lead to fibrosis and lymphoedema |
| Specific/Tuberculous Lymphangitis | M. tuberculosis involvement |
| Filarial Lymphangitis | Wuchereria bancrofti - leads to elephantiasis |
| Sclerosing Lymphangitis | Non-infectious, affects penile lymphatics |
Stages of Acute Lymphangitis:
- Stage 1 - Local: Red streaks at wound site, tender regional nodes
- Stage 2 - Spreading: Streaks extend, systemic fever, rigors
- Stage 3 - Systemic/Septicaemic: Bacteria enter bloodstream - bacteraemia, septic shock
Lymphoedema (consequence) - Primary vs Secondary:
- Primary: Milroy's disease (congenital agenesis of lymphatics)
- Secondary: Filariasis, post-mastectomy, post-radiation, tumour obstruction
6. LYMPHOMA - Definition
Lymphoma is a malignant neoplasm (cancer) arising from lymphocytes (B-cells, T-cells, or NK cells) primarily involving lymph nodes, spleen, or extranodal lymphoid tissue.
Two main categories:
- Hodgkin Lymphoma (HL) - Reed-Sternberg cells present
- Non-Hodgkin Lymphoma (NHL) - All other lymphomas, more heterogeneous
7. HODGKIN LYMPHOMA (HL)
WHO Classification (4 Types of Classical HL + 1 separate):
| Type | Features |
|---|---|
| 1. Nodular Sclerosis (most common ~70%) | Lacunar RS cells, collagen bands, young women, mediastinum involved |
| 2. Mixed Cellularity (~25%) | Classic RS cells, older men, EBV-associated, intermediate prognosis |
| 3. Lymphocyte-Rich | Many lymphocytes, rare RS cells, best prognosis |
| 4. Lymphocyte-Depleted (rarest) | Many RS cells, few lymphocytes, worst prognosis, elderly/HIV patients |
| 5. Nodular Lymphocyte Predominant HL (NLPHL) | Separate entity, "popcorn cells" (L&H cells), very indolent |
Key Features:
- Painless cervical/supraclavicular lymphadenopathy (most common presentation)
- Spreads contiguously (node to node, unlike NHL)
- Mediastinal adenopathy in >85% on staging
- B symptoms: Fever, night sweats, weight loss >10%
- Pel-Ebstein fever (cyclical fever) - classic but rare
- Alcohol-induced pain in lymph nodes (pathognomonic)
Ann Arbor Staging:
| Stage | Description |
|---|---|
| I | Single lymph node region |
| II | 2+ regions on SAME side of diaphragm |
| III | Both sides of diaphragm |
| IV | Diffuse extranodal (liver, bone marrow, lung) |
| +A/B | A = no B-symptoms; B = fever/sweats/weight loss |
Treatment:
- Stage I-II: ABVD chemotherapy (Adriamycin, Bleomycin, Vinblastine, DTIC) + radiotherapy
- Stage III-IV: ABVD or escalated BEACOPP
8. STOMATITIS & VINCENT'S ANGINA
Stomatitis:
Definition: Inflammation of the oral mucosa.

- Fever and malaise
- "Punched-out" ulcers on interdental papillae
- Associated with stress, poor hygiene, malnutrition, smoking
Treatment: Metronidazole (drug of choice) + penicillin + oral hygiene
9. RANULA - Bimanual Palpation Test
Ranula: A mucous retention cyst arising from sublingual salivary gland (floor of mouth). Named from "rana" (frog) - looks like a frog's belly.
Types:
- Simple ranula: Confined to floor of mouth (above mylohyoid)
- Plunging/Diving ranula: Extends through mylohyoid into neck (presents as neck swelling)
Bimanual Palpation Test:
- Method: One finger placed inside the mouth on the floor, the other hand palpates from outside under the chin simultaneously
- Finding: The cyst is felt as a soft, fluctuant, translucent, non-tender swelling
- Translucency test (+ve) - transilluminates (confirms cystic nature)
- In plunging ranula, the intraoral component may be small but a large soft neck mass is found on bimanual palpation
Key Features:
- Bluish-translucent cyst on floor of mouth
- Lateral to midline (unlike dermoid cyst which is midline)
- Treatment: Marsupialization or excision of sublingual gland
10. GASTRITIS - Types

- Thrombolysis for massive DVT threatening limb
13. VARICOSE VEINS - Tests & Management
Clinical Tests:
| Test | Method | Positive Result |
|---|---|---|
| Trendelenburg Test (Tourniquet Test) | Leg raised to empty veins, tourniquet at groin, patient stands up | Varices remain empty = saphenofemoral incompetence. Released tourniquet β rapid filling = confirms |
| Tap (Percussion) Test | Tap lower varicose vein, feel impulse higher up | Impulse transmitted = continuous column of blood, confirms connection |
| Cough Test | Ask patient to cough | Fluid thrill/impulse felt over varices = saphenofemoral incompetence |
| Perthes' Test | Tourniquet applied, patient walks | If varices increase = deep vein obstruction (don't strip) |
| Doppler Ultrasound | Over SFJ, asked to cough | Audible reflux confirms incompetence |
| Duplex Scan | Gold standard | Maps incompetence and deep veins |
Management:
- Conservative: Compression stockings, weight loss, leg elevation
- Sclerotherapy: Injection of sclerosant (small varices)
- Endovenous: EVLA (Endovenous Laser Ablation), RFA (Radiofrequency Ablation) - now first line
- Surgical: Trendelenburg's operation (saphenofemoral ligation + stripping of LSV) - now less common
14. ACUTE SUPPURATIVE PERITONITIS

- Rebound tenderness
- Obliteration of liver dullness (if free gas)
Management:
- Resuscitation: IV fluids, antibiotics (broad-spectrum: cephalosporin + metronidazole)
- Nasogastric tube decompression
- Emergency surgery: Laparotomy/laparoscopy - source control (repair/resection), peritoneal lavage
- ICU care if septic shock
