From ritual to asepsis: a short history of surgery before the twentieth century

Surgery is among the oldest branches of medical practice, but its transformation into a reliably survivable intervention is remarkably recent. For most of its recorded history, surgery was constrained by three persistent problems: the inability to control pain, the inability to control bleeding, and the inability to control infection. Each of these constraints shaped the scope of what could be attempted, who attempted it, and with what expectation of success. This short review traces the development of surgical practice from its earliest documented forms in antiquity through the nineteenth-century revolutions in anaesthesia and antisepsis, which together converted surgery from an act of last resort into a discipline capable of deliberate, elective intervention. Particular attention is given to the social status of the surgeon, the gradual separation of surgical knowledge from barbering and craft traditions, and the contingent nature of the discoveries that made modern operative medicine possible. 1. Antiquity and the evidence of early practice The archaeological record suggests that surgery, in some form, predates written medicine by several thousand years. Trephined skulls — cranial bones with circular holes deliberately cut or scraped through the vault — have been recovered from Neolithic sites across Europe, North Africa, and the Americas, with the earliest examples dating to roughly 6500 BCE (Gross, 2009). Evidence of bone remodelling around the trephination margins indicates that a substantial proportion of these patients survived the procedure, sometimes for years. The purposes of trephination remain debated; proposed explanations include the treatment of head injuries, the relief of intracranial pressure, and ritual or religious functions. Most likely, the practice served different purposes in different cultures. Documentary evidence of surgical practice appears in the Edwin Smith Papyrus, an Egyptian medical text dated to approximately 1600 BCE but probably copied from a source several centuries older (Breasted, 1930). The papyrus describes forty-eight cases of trauma, each presented with a systematic structure: examination, diagnosis, prognosis, and treatment. The text is notable for its empirical tone and for its willingness to categorise certain conditions as untreatable — an explicit acknowledgement of surgical limits that would largely disappear from Western medical writing for the next two millennia. In the Indian tradition, the Sushruta Samhita, compiled in its surviving form around the sixth century BCE, describes a considerably more ambitious surgical repertoire, including cataract couching, lithotomy for bladder stones, and an early technique for rhinoplasty using a pedicled forehead flap (Saraf and Parihar, 2007). The Sushrutan text also details over a hundred surgical instruments, a classification of injuries, and procedural descriptions that would not be substantially improved upon in Europe until the early modern period. 2. The Greco-Roman synthesis and its transmission Greek medicine inherited and systematised elements of Egyptian and Near Eastern surgical practice, but tended to subordinate surgery to internal medicine and dietetics. The Hippocratic corpus, assembled between the fifth and fourth centuries BCE, contains detailed discussions of fracture reduction, the reduction of dislocations, and the management of head wounds, but treats these as practical matters rather than as a distinct branch of knowledge (Jouanna, 1999). The famous aphorism that the physician should “do no harm” is sometimes interpreted as an injunction against surgical intervention specifically, though this reading is probably anachronistic. Roman medicine, largely imported from the Greek world, developed surgery considerably in the context of military practice. Aulus Cornelius Celsus, writing in the first century CE, provided the most comprehensive surgical treatise surviving from antiquity, describing procedures ranging from the extraction of arrow heads to the ligation of bleeding vessels (Celsus, trans. 1935). His famous enumeration of the four cardinal signs of inflammation — redness, swelling, heat, and pain — remained the basis of diagnostic reasoning for over a thousand years. Galen of Pergamon, active in the second century CE, produced an even more expansive anatomical and surgical corpus, though much of his anatomy was derived from animal dissection and contained errors that would constrain European practice until the Renaissance. With the fragmentation of the Western Roman Empire, much of this surgical knowledge was preserved and extended in the Islamic world. Abu al-Qasim al-Zahrawi, known in Latin Europe as Albucasis, produced in the tenth century a thirty-volume medical encyclopaedia whose final volume — the Kitab al-Tasrif — constituted the most influential surgical text of the medieval period (Elgood, 2010). His descriptions of instruments, cauterisation techniques, and operative procedures were translated into Latin in the twelfth century and remained in use in European medical schools until the seventeenth. 3. The medieval separation of surgery and medicine In medieval Europe, surgery developed along an institutional path that diverged sharply from internal medicine. Following the Fourth Lateran Council of 1215, which forbade clergy from shedding blood, surgical practice was increasingly delegated to lay practitioners outside the university system. The university-trained physician, versed in humoral theory and textual commentary, occupied a higher social and professional station than the surgeon, who was understood as a craftsman working with his hands (Siraisi, 1990). This division was formalised in many European cities through the organisation of barber-surgeons’ guilds. The barber-surgeon performed bloodletting, tooth extraction, the treatment of wounds, the setting of fractures, and minor operative procedures, typically learned through apprenticeship rather than formal study. The elevated surgeon — the practitioner of the “long robe,” distinguished from the “short robe” of the barber — emerged slowly and unevenly, often through the patronage of military or royal service. Ambroise Paré, surgeon to four French kings in the sixteenth century, exemplified this transition: trained as a barber-surgeon, he reintroduced ligature for the control of haemorrhage during amputation, in place of the older and more destructive practice of cautery with boiling oil (Paré, trans. 1952). 4. The anatomical revolution The publication of Andreas Vesalius’s De Humani Corporis Fabrica in 1543 marked the beginning of a gradual reorientation of surgical knowledge around direct anatomical observation. Vesalius’s insistence on personal dissection, and his willingness to correct Galenic errors on the basis of cadaveric evidence, inaugurated a tradition that would eventually produce the detailed surgical anatomy of the eighteenth century (O’Malley, 1964). The consequences for practice were slower to materialise than for knowledge, however. A surgeon in 1750 possessed a considerably more accurate map of the human body than one in 1550, but was scarcely more able to intervene upon it without killing the patient. The eighteenth century saw significant developments in procedural technique, particularly in lithotomy, amputation, and the management of obstetric complications. John Hunter, working in London in the second half of the century, combined clinical practice with systematic comparative anatomy and experimental physiology, and is often credited with establishing surgery as a scientific discipline rather than a trade (Moore, 2005). The founding of dedicated surgical societies, the awarding of formal qualifications, and the gradual inclusion of surgical training within medical education all belong to this period. 5. The nineteenth-century revolutions Despite these developments, surgery at the beginning of the nineteenth century remained constrained by the three persistent problems named at the outset. Operations were performed on conscious patients, at speed, with mortality rates from post-operative infection that frequently exceeded fifty per cent for major procedures. The transformation of this situation over the course of roughly three decades constitutes one of the most consequential episodes in the history of medicine. The first of the three problems to yield was pain. The public demonstration of ether anaesthesia by William Morton at the Massachusetts General Hospital on 16 October 1846 is conventionally taken as the founding moment of modern anaesthesia, though earlier experiments with nitrous oxide and other agents had been conducted without receiving wide recognition (Fenster, 2001). The rapid international adoption of ether, and subsequently of chloroform, fundamentally altered what was operationally possible: longer, more deliberate, and more complex procedures became feasible for the first time. The control of bleeding, long the central preoccupation of surgical technique, was advanced incrementally through the nineteenth century by improvements in ligature materials, the development of haemostatic forceps, and a better understanding of vascular anatomy. No single discovery transformed the field in the manner of anaesthesia, but the cumulative effect was substantial. The third problem — infection — yielded last, and to the intervention whose consequences were perhaps the most far-reaching. Joseph Lister, building on Pasteur’s demonstration of the microbial basis of fermentation and putrefaction, introduced carbolic acid as an antiseptic agent in surgical practice at the Glasgow Royal Infirmary in 1865 (Lister, 1867). The initial reception of Lister’s methods was mixed — the theoretical framework was unfamiliar to many surgeons, and the practical implementation was cumbersome — but by the 1880s the principle of antisepsis had been broadly accepted, and was being superseded by the more rigorous practice of asepsis, in which instruments, dressings, and the operative field itself were rendered free of microorganisms from the outset rather than treated chemically during the procedure (Worboys, 2000). 6. Conclusion The transformation of surgery from a last-resort intervention into a systematic discipline was neither linear nor inevitable. It depended on the convergence of developments in anatomy, pharmacology, microbiology, and technique, each of which was contingent upon prior intellectual and institutional conditions. The modern surgeon inherits a practice whose basic operational premises — a patient who feels no pain, a field that does not bleed uncontrollably, and a wound that does not fester — would have appeared fantastical to practitioners of any earlier period. That these premises are now taken for granted is perhaps the clearest measure of how recent, and how fragile, the achievement is.
