TOPIC 1. HISTORICAL DEVELOPMENT OF SURGERY
1. Definition and scope
Surgery is the branch of medicine concerned with the diagnosis and treatment of disease, injury and deformity by operative and other procedural methods. Modern surgery combines anatomical knowledge, physiological understanding, aseptic technique, anaesthesia, imaging, critical care and minimally invasive technology.
2. Major historical milestones
Ancient period: Trepanation, wound treatment, drainage and basic fracture care were practised in several ancient civilisations. The Edwin Smith Papyrus contains early systematic descriptions of traumatic injuries.
Hippocratic medicine: Emphasised clinical observation, prognosis and rational management of wounds and fractures. Infection and anaesthesia remained major limitations.
Roman and medieval surgery: Galen influenced anatomy and medicine for centuries. Surgical practice developed through military medicine, Arabic and Persian scholarship, and later European universities.
Renaissance: Andreas Vesalius advanced anatomical knowledge through direct human dissection. Ambroise Paré improved battlefield wound care and promoted ligatures for haemostasis instead of routine cauterisation.
18th–19th centuries: Pathological anatomy, improved surgical instruments and hospital organisation developed. Ether anaesthesia was publicly demonstrated in 1846; chloroform subsequently became widely used. Anaesthesia made longer and more complex operations possible.
Antisepsis and asepsis: Ignaz Semmelweis demonstrated the importance of hand hygiene in preventing puerperal fever. Joseph Lister introduced antiseptic surgical methods using carbolic acid. Sterilisation, clean operating theatres, gowns, gloves and aseptic technique transformed surgical safety.
Microbiology: Pasteur's work established the role of microorganisms in infection; Koch's work linked specific organisms to disease. This provided the scientific basis for infection prevention and antimicrobial treatment.
20th century: Blood transfusion, antibiotics, safer anaesthesia, endotracheal intubation, intensive care, electrosurgery, vascular surgery, transplantation and advanced imaging expanded operative possibilities.
Contemporary surgery: Laparoscopy, endoscopy, interventional radiology, robotic assistance, microsurgery, enhanced recovery pathways and precision/oncological surgery have improved visualisation, reduced access trauma and individualised care.
3. The foundations of safe modern surgery
- Accurate diagnosis and appropriate patient selection.
- Knowledge of anatomy, physiology, pathology and the natural history of disease.
- Anaesthesia, analgesia, resuscitation and monitoring.
- Sterile instruments, aseptic technique and rational antimicrobial prophylaxis.
- Reliable haemostasis, gentle tissue handling and sound surgical technique.
- Postoperative surveillance, prevention of venous thromboembolism and infection, nutrition, rehabilitation and audit.
Exam point: Three developments fundamentally changed surgery: anaesthesia made painless operations possible; antisepsis/asepsis reduced infection; and blood transfusion plus antibiotics and modern critical care made complex surgery safer.
