A standardized breakdown of high-yield General Surgery topics, structured in the format of major board exams (such as NRE Step 1, FCPS Part 1, USMLE Step 2 CK, and international licensing syllabi): ​1. Surgical Principles & Critical Care ​Wound Healing & Surgical Site Infection (SSI): Phases of wound healing (hemostasis, inflammation, proliferation, remodeling), primary vs. secondary intention, hypertrophic scars vs. keloids, SSI risk factors, and prophylactic antibiotic timing. ​Shock & Fluid Resuscitation: Pathophysiology and management of Hypovolemic, Cardiogenic, Septic, and Anaphylactic shock. Crystalloid vs. colloid use, Parkland formula for burns (4\text{ mL} \times \text{weight in kg} \times \% \text{TBSA}), and massive transfusion protocols. ​Hemostasis, Blood Transfusions & DVT: Coagulation cascades, blood product indications, acute vs. delayed transfusion reactions, Virchow’s triad, and DVT/pulmonary embolism prophylaxis. ​Metabolic Response to Injury & Nutrition: Endocrine and cytokine response to stress, starvation vs. stress metabolism, Enteral vs. Total Parenteral Nutrition (TPN) indications and complications. ​2. Gastrointestinal & Abdominal Surgery ​Esophagus & Stomach: Achalasia, GERD, Esophageal Carcinoma, Peptic Ulcer Disease (PUD complications: bleeding, perforation), and Gastric Adenocarcinoma staging/surgical approaches. ​Hepatobiliary & Pancreas: Cholelithiasis, Acute Cholecystitis (Murphy's sign), Choledocholithiasis, Acute Cholangitis (Charcot's Triad & Reynolds' Pentad), Acute Pancreatitis (Ranson's criteria, BISAP score), and Pancreatic Head Adenocarcinoma (Whipple procedure). ​Small Intestine & Appendicitis: Small bowel obstruction (mechanical vs. paralytic ileus), Meckel’s diverticulum, Inflammatory Bowel Disease (Crohn's vs. Ulcerative Colitis), and Acute Appendicitis (Alvarado score). ​Colorectal & Anal Conditions: Colorectal Cancer (staging, CEA marker, Hartmann's procedure vs. LAR/APR), Diverticulitis, Hemorrhoids, Perianal Abscess, and Fistula-in-ano. ​Abdominal Wall & Hernias: Inguinal Hernia (Direct vs. Indirect anatomy, Nyhus classification, Lichtenstein repair), Femoral, Ventral, Incisional, and Strangulated hernias. ​3.
