History of intersex surgery

From Wikipedia, the free encyclopedia

The history of intersex surgery is intertwined with the development of the specialities of pediatric surgery, pediatric urology, and pediatric endocrinology, with our increasingly refined understanding of sexual differentiation, with the development of political advocacy groups united by a human qualified analysis, and in the last decade by doubts as to efficacy, and controversy over when and even whether some procedures should be performed.

Prior to the medicalization of intersex, Canon and common law referred to a person's sex as male, female or hermaphrodite, with legal rights as male or female depending on the characteristics that appeared most dominant. The foundation of common law, the Institutes of the Lawes of England described how a hermaphrodite could inherit "either as male or female, according to that kind of sexe which doth prevaile." Single cases have been described by legal cases sporadically over the centuries. Diodorus Siculus is the first to record medical procedures associated with intersex gender affirmation surgery in his account of the life of Callon of Epidaurus. Modern ideas of medicalization of intersex and birth defects can be traced to French anatomist Isidore Geoffroy Saint-Hilaire (1805–1861), who pioneered the field of teratology.

Since the 1920s surgeons have attempted to "fix" an increasing variety of conditions. Success has often been partial and surgery is often associated with minor or major, transient or permanent complications. Techniques in all fields of surgery are frequently revised in a quest for higher success rates and lower complication rates. Some surgeons, well aware of the immediate limitations and risks of surgery, feel that significant rates of imperfect outcomes are no scandal (especially for the more severe and disabling conditions). Instead they see these negative outcomes as a challenge to be overcome by improving the techniques. Genital reconstruction evolved within this tradition. In recent decades, nearly every aspect of this perspective has been called into question, with increasing concern regarding the human rights implications of medical interventions.

Surgical pioneering and constructed gender

Genital reconstructive surgery was pioneered between 1930 and 1960 by urologist Hugh Hampton Young and other surgeons at Johns Hopkins Hospital in Baltimore and other major university centers. Understanding of intersex conditions was relatively primitive, based on identifying the type of gonad(s) by palpation or by surgery. Since ability to determine even the type of gonads in infancy was limited, sex of assignment and rearing were determined mainly by the appearance of the external genitalia. Most of Young's intersex patients were adults willingly seeking his help with physical problems of genital function.

Demand for surgery increased dramatically with better understanding of the condition congenital adrenal hyperplasia (CAH) and availability of a new treatment (cortisone) by Lawson Wilkins, Frederick Bartter and others around 1950. For the first time, virilized infants with this variation were surviving and could be operated upon. A conflation was then established between life-saving treatment and cosmetic surgeries. Hormone assays and karyotyping to ascertain sex chromosomes, and the availability of testosterone for treatment led to partial understanding of androgen insensitivity syndrome. Within a decade, most intersex cases could be accurately diagnosed and their future development predicted with some degree of confidence.

As the number of children with intersex conditions referred to Lawson Wilkins' new pediatric endocrinology clinic at Hopkins increased, it was recognized that doctors "couldn't tell by looking" at the external genitalia, and many errors of diagnosis based on outward appearance had led to anomalous sex assignments. Although it seems obvious now that a doctor could not announce to an eight-year-old boy and his parents that "we have just discovered that you are 'really' a girl, with female chromosomes, and ovaries and uterus inside, and we recommend that you change your sex to match your chromosomes and internal organs," a few such events occurred around the world as doctors and parents tried to make use of new information.

Genital reconstructive surgery at that time was primarily performed on older children and adults. In the early 1950s, it consisted primarily of the ability to remove an unwanted or nonfunctional gonad, to bring a testis into a scrotum, to repair a milder chordee or to change the position of the urethra in hypospadias, to widen a vaginal opening, and to remove a clitoris.

John Money, a pediatric clinical psychologist in the new "Psychohormonal Research Unit" at Hopkins, and his partners, John and Joan Hampson, analyzed these assignments and reassignments in an attempt to learn the timing and sources of gender identity. In most of these patients, gender identity seemed to follow the sex of assignment and sex of rearing more closely than it did genes or hormones. This apparent primacy of social learning over biology became part of the intellectual underpinning of the feminist movement of the 1960s. In its application to children with intersex conditions, this thesis that sex was a many-faceted social construction changed the management of ambiguous genitalia from determination of the baby's real sex (by checking gonads or chromosomes) to determination of what sex should be assigned.

The most common intersex surgery offered in childhood was amputation of the clitoris and widening of the vaginal opening to make the genitals of a girl with CAH appear more conformed to the expectations. However, by the late 1950s surgical techniques for transforming an adult man into a woman were being developed in response to requests for such surgery from transsexuals.

Rise of infant surgery and "nurture over nature"

By the 1960s, the young specialties of pediatric surgery and pediatric urology at children's hospitals were universally admired for bringing infant birth defect surgery to new levels of success and safety. These specialized surgeons began to repair wider varieties of birth defects at younger ages with better results. Earlier correction reduced the social "differentness" of a child with a cleft lip, or club foot, or skull malformation, or could save the life of an infant with spina bifida.

Genital corrective surgeries in infancy were justified by (1) the belief that genital surgery is less emotionally traumatic if performed before the age of long-term memory, (2) the assumption that a firm gender identity would be best supported by genitalia that "looked the part," (3) the preference of parents for an "early fix," and (4) the observation of many surgeons that connective tissue, skin, and organs of infants heal faster, with less scarring than those of adolescents and adults. However, one of the drawbacks of surgery in infancy was that it would be decades before outcomes in terms of adult sexual function and gender identity could be assessed.

In North American and European societies, the 1960s saw the beginning of the "sexual revolution", characterized by increased public interest and discussion about sexuality, recognition of the value of sexuality in people's lives, the separation of sexuality from reproduction by increasing availability of contraception, the lessening of many social barriers and inhibitions related to sexual behavior, and social acknowledgment of women's sexuality. In this era, genes and hormones were thought not to have a strong influence on any aspect of human psychosexual development, gender identity, or sexual orientation.

The 1970s and 1980s were perhaps the decades when surgery and surgery-supported sex reassignment were most uncritically accepted in academic opinion, in most children's hospitals, and by society at large. In this context, enhancing the ability of people born with abnormalities of the genitalia to engage in "normal" heterosexual intercourse as adults assumed increasing importance as a goal of medical management. Many felt that a child could not become a happy adult if his penis was too small to insert in a vagina, or if her vagina was too small to receive a penis.

By 1970, surgeons still considered it easier to "dig a hole" than "build a pole", but had abandoned "barbaric" clitorectomies in favor of "nerve sparing" clitoral recession and promised orgasms when the girls grew up. Pediatric endocrinology, surgery, child psychology, and sexuality textbooks recommended sex reassignment for a male whose penis was irreparably malformed or "too small to stand to urinate or penetrate a vagina," because the surgeons claimed to be able to construct vaginas where none existed. The majority of these genetic males who were reassigned and surgically converted had cloacal exstrophy-type malformations or extreme micropenis (typically less than 1.5 cm). In 1972 John Money published his influential text on the development of gender identity, and reported successful reassignment at age 22 months of a boy (David Reimer) who had lost his penis to a surgical accident. This experiment proved not to be as successful as Money claimed. David Reimer grew up as a girl, but never identified as one. Academic sexologist Milton Diamond later reported that Reimer failed to identify as female since the age of 9 to 11, making the transition to living as a male at age 15. Reimer later went public with his story to discourage similar medical practices. He later died by suicide, owing to suffering years of severe depression, financial instability, and a troubled marriage.

Complications arise

Throughout the 1980s pediatric surgery textbooks recommended female assignment and feminizing reconstructive surgery for XY infants with a severely inadequate phallus. Nevertheless, in the 1980s several factors began to induce a decline in the frequency of certain types of genital surgery. Pediatric endocrinologists had realized that some boys with micropenis had deficiency of growth hormone which could be improved with hormones rather than surgery, and over the next decade a couple of reports suggested adult outcome as males was not as bad as expected for the boys with micropenis who had not had surgery. Although textbooks were slower to reflect the change, few reassignment surgeries for isolated micropenis were carried out by the 1990s.

In the 1980s research in both animals and humans began to provide evidence that sex hormones play an important role in early life in promoting or constraining adult sex-dimorphic sexual behavior and even gender identity. Examples of apparent androgen determination of gender identity in XY people with 5-alpha-reductase deficiency in the Dominican Republic had been published, along with reports of masculinized behavior in girls with congenital adrenal hyperplasia (CAH), and unsatisfactory sexual outcomes in adult women with CAH. Many endocrinologists were becoming skeptical that reassignment of genetic males to females was just a matter of learning and appearance, or that the newer clitoral reductions would be more successful than clitoral recessions.

However, feminizing reconstructive surgery continued to be recommended and performed throughout the 1990s on most virilized infant girls with CAH, as well as infants with ambiguity due to androgen insensitivity syndrome, gonadal dysgenesis, and some XY infants with severe genital birth defects such as cloacal exstrophy. Masculinizing reconstructive surgery continued on boys with severe hypospadias and the other conditions outlined above, with continued modifications and refinements intended to reduce unsatisfactory outcomes.

Patient advocacy groups speak up

By 1990, biological factors were being reported for a wide variety of human behaviors and personality characteristics. The idea that culture accounted for all the differences between men and women seemed as obsolete as psychotherapy for homosexuality.

A more abrupt and sweeping re-evaluation of reconstructive genital surgery began about 1993, triggered by a combination of factors. One of the major factors was the rise of patient advocacy groups that expressed dissatisfaction with several aspects of their own past treatments. The Intersex Society of North America was the most influential and persistent, and advocated postponing genital surgery until a child is old enough to display a clear gender identity and consent to the surgery. Recommendations from these voices ranged from the unexceptionable (ending shame and secrecy, and providing more accurate information and counseling) to the radical (assigning a third sex or no sex at all to intersex infants). The idea that possession of abnormal genitalia in and of itself does not constitute a medical crisis was stressed. The claims of advocacy groups have been resisted. In response to a demonstration by members of the Intersex Society of North America outside the annual conference of the American Academy of Pediatrics in October 1996, the Academy issued a press statement stating that:

  • The Academy is deeply concerned about the emotional, cognitive, and body image development of intersexuals, and believes that successful early genital surgery minimizes these issues.
  • Research on children with ambiguous genitalia has shown that a person’s sexual body image is largely a function of socialization, and children whose genetic sexes are not clearly reflected in external genitalia can be raised successfully as members of either sexes if the process begins before 2 1/2 years.
  • Management and understanding of intersex conditions has significantly improved, particularly over the last several decades...

In addition to ignoring patients' voices, physicians involved in intersex care had embarrassingly little long-term outcome data to support their claims. In 1997 a patient account was published which could not be ignored. David Reimer's tragic story, told in both popular and medical publications, was widely interpreted by the public and many physicians as a cautionary tale of medical hubris, of the folly of attempting to foil nature with nurture, of the importance of early hormones on brain development, and the risks and limitations of surgery. Some clinicians proposed a moratorium on pediatric sex reassignment, particularly of undervirilized males as females, due to a lack of data that rearing or appearance of genitalia play a major part in gender identity development. Those clinicians encouraged delaying surgery until elected by adolescents to preserve sexual sensitivity.

Similar controversy occurred in Europe and Latin America. In 1999 Colombia's constitutional court limited the ability of parents to consent to genital surgery for infants with intersex conditions. A number of advocacy groups argue against many forms of genital surgery in childhood. In 2001, British surgeons argued for deferring vaginoplasty until adulthood on grounds of poor outcomes for women who were operated on as infants.

Outcomes and evidence

A 2004 paper by Heino Meyer-Bahlburg and others examined outcomes from early surgeries in individuals with XY variations, at one patient centre. The study has been used to support claims that "‘the majority of women...have clearly favored genital surgery at an earlier age" but the study was criticized by Baratz and Feder for neglecting to inform respondents that:

(1) not having surgery at all might be an option; (2) they might have had lower rates of reoperation for stenosis if surgery were performed later, or (3) that significant technical improvements that were expected to improve outcomes had occurred in the 13 or 14 years between when they underwent early childhood surgery and when it might have been deferred until after puberty.

In 2006, an invited group of clinicians met in Chicago and reviewed clinical evidence and protocols, argued that and adopted a new term for intersex conditions: "Disorders of sex development" (DSD). More specifically, these terms refer to "congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical." The term has been controversial and not widely adopted outside clinical settings: the World Health Organization and many medical journals still refer to intersex traits or conditions. Academics like Georgiann Davis and Morgan Holmes, and clinical psychologists like Tiger Devore argue that the term DSD was designed to "reinstitutionalise" medical authority over intersex bodies.

On surgical rationales and outcomes, the Consensus Statement on Intersex Disorders and their Management stated that:

It is generally felt that surgery that is carried out for cosmetic reasons in the first year of life relieves parental distress and improves attachment between the child and the parents. The systematic evidence for this belief is lacking. ... information across a range of assessments is insufficient ... outcomes from clitoroplasty identify problems related to decreased sexual sensitivity, loss of clitoral tissue, and cosmetic issues ... Feminising as opposed to masculinising genitoplasty requires less surgery to achieve an acceptable outcome and results in fewer urological difficulties... Long term data on sexual function and quality of life among those assigned female as well as male show great variability. There are no controlled clinical trials of the efficacy of early (less than 12 months of age) versus late surgery (in adolescence and adulthood), or of the efficacy of different techniques.

Data presented in recent years suggests that little has changed in practice. Creighton and others in the UK have found that there have been few audits of the implementation of the 2006 statement, clitoral surgeries on under-14s have increased since 2006, and "recent publications in the medical literature tend to focus on surgical techniques with no reports on patient experiences". A 2014 civil society submission to the World Health Organization cited data from a large German Netzwerk DSD/Intersexualität study:

In a study in Lübeck conducted between 2005 and 2007 ... 81% of 439 individuals had been subjected to surgeries due to their intersex diagnoses. Almost 50% of participants reported psychological problems. Two thirds of the adult participants drew a connection between sexual problems and their history of surgical treatment. Participating children reported significant disturbances, especially within family life and physical well-being – these are areas that the medical and surgical treatment was supposed to stabilize.

A 2016 Australian study of persons born with atypical sex characteristics found that "strong evidence suggesting a pattern of institutionalised shaming and coercive treatment of people". Large majorities of respondents opposed standard clinical protocols.

A 2016 follow-up to the 2006 Consensus Statement, termed a Global Disorders of Sex Development Update stated,

There is still no consensual attitude regarding indications, timing, procedure and evaluation of outcome of DSD surgery. The levels of evidence of responses given by the experts are low (B and C), while most are supported by team expertise... Timing, choice of the individual and irreversibility of surgical procedures are sources of concerns. There is no evidence regarding the impact of surgically treated or non-treated DSDs during childhood for the individual, the parents, society or the risk of stigmatization... Physicians working with these families should be aware that the trend in recent years has been for legal and human rights bodies to increasingly emphasize preserving patient autonomy.

A 2016 paper on "Surgery in disorders of sex development (DSD) with a gender issue" repeated many of the same claims, but without reference to human rights norms. A commentary to that article by Alice Dreger and Ellen Feder criticized that omission, stating that issues have barely changed in two decades, with "lack of novel developments", while "lack of evidence appears not to have had much impact on physicians’ confidence in a standard of care that has remained largely unchanged." Another 2016 commentary stated that the purpose of the 2006 Consensus Statement was to validate existing practices, "The authoritativeness and “consensus” in the Chicago statement lies not in comprehensive clinician input or meaningful community input, but in its utility to justify any and all forms of clinical intervention."

Recent developments

Institutions like the Swiss National Advisory Commission on Biomedical Ethics, the Australian Senate, the Council of Europe, World Health Organization, and UN Office of the High Commissioner for Human Rights and Special Rapporteur on Torture have all published reports calling for changes to clinical practice and an end to harmful practices.

In 2011, Christiane Völling won the first successful case brought against a surgeon for non-consensual surgical intervention. The Regional Court of Cologne, Germany, awarded her €100,000.

In April 2015, Malta became the first country to recognize a right to bodily integrity and physical autonomy, and outlaw non-consensual modifications to sex characteristics. The Act was widely welcomed by civil society organizations.

In 2017, Human Rights Watch and Interact Advocates for Intersex Youth published a report documenting the negative effects of medically unnecessary surgeries on intersex children in the US, as well as the pressure placed on parents to consent to the operations without full information. California State Legislature passed a resolution condemning the practice in 2018.

The same year, Amnesty International published a report on the situation of intersex persons in Denmark and Germany and launched a campaign for intersex human's rights: "First, Do No Harm: ensuring the rights of children born intersex".

On July 28, 2020, Lurie Children's Hospital became the first children's hospital in the United States to cease medically unnecessary, cosmetic surgery on intersex infants and publicly apologize to past intersex individuals harmed by such surgeries.

History of surgery

From Wikipedia, the free encyclopedia
 

Surgery is the branch of medicine that deals with the physical manipulation of a bodily structure to diagnose, prevent, or cure an ailment. Ambroise Paré, a 16th-century French surgeon, stated that to perform surgery is, "To eliminate that which is superfluous, restore that which has been dislocated, separate that which has been united, join that which has been divided and repair the defects of nature."

Since humans first learned how to make and handle tools, they have employed their talents to develop surgical techniques, each time more sophisticated than the last; however, until the industrial revolution, surgeons were incapable of overcoming the three principal obstacles which had plagued the medical profession from its infancy — bleeding, pain and infection. Advances in these fields have transformed surgery from a risky "art" into a scientific discipline capable of treating many diseases and conditions.

Origins

The first surgical techniques were developed to treat injuries and traumas. Early surgical procedures were carried out in the Indian subcontinent by Sushruta, one of a number of individuals who has been called "the father of surgery". A combination of archaeological and anthropological studies offer insight into much earlier techniques for suturing lacerations, amputating unsalvageable limbs, and draining and cauterizing open wounds. Many examples exist: some Asian tribes used a mix of saltpeter and sulfur that was placed onto wounds and lit on fire to cauterize wounds; the Dakota people used the quill of a feather attached to an animal bladder to suck out purulent material; the discovery of needles from the Stone Age seems to suggest they were used in the suturing of cuts (the Maasai used needles of acacia for the same purpose); and tribes in India and South America developed an ingenious method of sealing minor injuries by applying termites or scarabs who bit the edges of the wound and then twisted the insects' neck, leaving their heads rigidly attached like staples.

Trepanation

The oldest operation for which evidence exists is trepanation (also known as trepanning, trephination, trephining or burr hole from Greek τρύπανον and τρυπανισμός), in which a hole is drilled or scraped into the skull for exposing the dura mater to treat health problems related to intracranial pressure and other diseases. In the case of head wounds, surgical intervention was implemented for investigating and diagnosing the nature of the wound and the extent of the impact while bone splinters were removed preferably by scraping followed by post operation procedures and treatments for avoiding infection and aiding in the healing process. Evidence has been found in prehistoric human remains from Proto-Neolithic and Neolithic times, in cave paintings, and the procedure continued in use well into recorded history (being described by ancient Greek writers such as Hippocrates). Out of 120 prehistoric skulls found at one burial site in France dated to 6500 BCE, 40 had trepanation holes. Folke Henschen, a Swedish doctor and historian, asserts that Soviet excavations of the banks of the Dnieper River in the 1970s show the existence of trepanation in Mesolithic times dated to approximately 12000 BCE. The remains suggest a belief that trepanning could cure epileptic seizures, migraines, and certain mental disorders.

There is significant evidence of healing of the bones of the skull in prehistoric skeletons, suggesting that many of those that proceeded with the surgery survived their operation.[citation needed] In some studies, the rate of survival surpassed 50%.

Setting bones

Examples of healed fractures in prehistoric human bones, suggesting setting and splinting have been found in the archeological record. Among some treatments used by the Aztecs, according to Spanish texts during the conquest of Mexico, was the reduction of fractured bones: "...the broken bone had to be splinted, extended and adjusted, and if this was not sufficient an incision was made at the end of the bone, and a branch of fir was inserted into the cavity of the medulla..." Modern medicine developed a technique similar to this in the 20th century known as medullary fixation.

Anesthesia

Bloodletting

Hirudo medicinalis. Leeches for bloodletting

Bloodletting is one of the oldest medical practices, having been practiced among diverse ancient peoples, including the Mesopotamians, the Egyptians, the Greeks, the Mayans, and the Aztecs. In Greece, bloodletting was in use around the time of Hippocrates, who mentions bloodletting but in general relied on dietary techniques. Erasistratus, however, theorized that many diseases were caused by plethoras, or overabundances, in the blood, and advised that these plethoras be treated, initially, by exercise, sweating, reduced food intake, and vomiting. Herophilus advocated bloodletting. Archagathus, one of the first Greek physicians to practice in Rome, practiced bloodletting extensively. The art of bloodletting became very popular in the West, and during the Renaissance one could find bloodletting calendars that recommended appropriate times to bloodlet during the year and books that claimed bloodletting would cure inflammation, infections, strokes, manic psychosis and more.

Antiquity

Mesopotamia

The Sumerians saw sickness as a divine punishment imposed by different demons when an individual broke a rule. For this reason, to be a physician, one had to learn to identify approximately 6,000 possible demons that might cause health problems. To do this, the Sumerians employed divining techniques based on the flight of birds, position of the stars and the livers of certain animals. In this way, medicine was intimately linked to priests, relegating surgery to a second-class medical specialty.

Nevertheless, the Sumerians developed several important medical techniques: in Ninevah archaeologists have discovered bronze instruments with sharpened obsidian resembling modern day scalpels, knives, trephines, etc. The Code of Hammurabi, one of the earliest Babylonian code of laws, itself contains specific legislation regulating surgeons and medical compensation as well as malpractice and victim's compensation:

215. If a physician make a large incision with an operating knife and cure it, or if he open a tumor (over the eye) with an operating knife, and saves the eye, he shall receive ten shekels in money.

217. If he be the slave of some one, his owner shall give the physician two shekels.

218. If a physician make a large incision with the operating knife, and kill him, or open a tumor with the operating knife, and cut out the eye, his hands shall be cut off.

220. If he had opened a tumor with the operating knife, and put out his eye, he shall pay half his value.

Egypt

Pictures of surgery tools at Kom Ombo, Egypt

Around 3100 BCE Egyptian civilization began to flourish when Narmer, the first Pharaoh of Egypt, established the capital of Memphis. Just as cuneiform tablets preserved the knowledge of the ancient Sumerians, hieroglyphics preserved the Egyptians'.

In the first monarchic age (2700 BCE) the first treatise on surgery was written by Imhotep, the vizier of Pharaoh Djoser, priest, astronomer, physician and first notable architect. So much was he famed for his medical skill that he became the Egyptian god of medicine. Other famous physicians from the Ancient Empire (from 2500 to 2100 BCE) were Sachmet, the physician of Pharaoh Sahure and Nesmenau, whose office resembled that of a medical director.

On one of the doorjambs of the entrance to the Temple of Memphis there is the oldest recorded engraving of a medical procedure: circumcision and engravings in Kom Ombo, Egypt depict surgical tools. Still of all the discoveries made in ancient Egypt, the most important discovery relating to ancient Egyptian knowledge of medicine is the Ebers Papyrus, named after its discoverer Georg Ebers. The Ebers Papyrus, conserved at the University of Leipzig, is considered one of the oldest treaties on medicine and the most important medical papyri. The text is dated to about 1550 BCE and measures 20 meters in length. The text includes recipes, a pharmacopoeia and descriptions of numerous diseases as well as cosmetic treatments. It mentions how to surgically treat crocodile bites and serious burns, recommending the drainage of pus-filled inflammation but warns against certain diseased skin.

Edwin Smith Papyrus

Plates vi and vii of the Edwin Smith Papyrus (around the 17th century BC), among the earliest medical texts

The Edwin Smith Papyrus is a lesser known papyrus dating from the 1600 BCE and only 5 meters in length. It is a manual for performing traumatic surgery and gives 48 case histories. The Smith Papyrus describes a treatment for repairing a broken nose, and the use of sutures to close wounds. Infections were treated with honey. For example, it gives instructions for dealing with a dislocated vertebra:

Thou shouldst bind it with fresh meat the first day. Thou shouldst loose his bandages and apply grease to his head as far as his neck, (and) thou shouldst bind it with ymrw. Thou shouldst treat it afterwards with honey every day, (and) his relief is sitting until he recovers.

Mehrgarh

Teeth discovered from a Neolithic graveyard in Mehrgarh had shown signs of drilling. Analysis of the teeth shows prehistoric people might have attempted curing toothache with drills made from flintheads.

Ayurveda

Sushruta (c. 600 BCE) is considered as the "founding father of surgery". His period is usually placed between the period of 1200 BC - 600 BC. One of the earliest known mention of the name is from the Bower Manuscript where Sushruta is listed as one of the ten sages residing in the Himalayas. Texts also suggest that he learned surgery at Kasi from Lord Dhanvantari, the god of medicine in Hindu mythology. He was an early innovator of plastic surgery who taught and practiced surgery on the banks of the Ganges in the area that corresponds to the present day city of Varanasi in Northern India. Much of what is known about Sushruta is in Sanskrit contained in a series of volumes he authored, which are collectively known as the Sushruta Samhita. It is one of the oldest known surgical texts and it describes in detail the examination, diagnosis, treatment, and prognosis of numerous ailments, as well as procedures on performing various forms of cosmetic surgery, plastic surgery and rhinoplasty.

Greece and the Hellenized world

Engraving of Hippocrates by Peter Paul Rubens, 1638.

Surgeons are now considered to be specialized physicians, whereas in the early ancient Greek world a trained general physician had to use his hands (χείρ in Greek) to carry out all medical and medicinal processes including for example the treating of wounds sustained on the battlefield, or the treatment of broken bones (a process called in Greek: χειρουργείν).

In The Iliad Homer names two doctors, “the two sons of Asklepios, the admirable physicians Podaleirius and Machaon and one acting doctor, Patroclus. Because Machaon is wounded and Podaleirius is in combat Eurypylus asks Patroclus “to cut out this arrow from my thigh, wash off the blood with warm water and spread soothing ointment on the wound."

Hippocrates

The Hippocratic Oath, written in the 5th century BC provides the earliest protocol for professional conduct and ethical behavior a young physician needed to abide by in life and in treating and managing the health and privacy of his patients. The multiple volumes of the Hippocratic corpus and the Hippocratic Oath elevated and separated the standards of proper Hippocratic medical conduct and its fundamental medical and surgical principles from other practitioners of folk medicine often laden with superstitious constructs, and/or of specialists of sorts some of whom would endeavor to carry out invasive body procedures with dubious consequences, such as lithotomy. Works from the Hippocratic corpus include; On the Articulations or On Joints, On Fractures, On the Instruments of Reduction, The Physician's Establishment or Surgery, On Injuries of the Head, On Ulcers, On Fistulae, and On Hemorrhoids.

Celsus and Alexandria

Herophilus of Chalcedon and Erasistratus of Ceos were two great Alexandrians who laid the foundations for the scientific study of anatomy and physiology. Alexandrian surgeons were responsible for developments in ligature (hemostasis), lithotomy, hernia operations, ophthalmic surgery, plastic surgery, methods of reduction of dislocations and fractures, tracheotomy, and mandrake as anesthesia. Most of what we know of them comes from Celsus and Galen of Pergamum (Greek: Γαληνός)

Galen

Galen's On the Natural Faculties, Books I, II, and III, is an excellent paradigm of a very accomplished Greek surgeon and physician of the 2nd century Roman era, who carried out very complex surgical operations and added significantly to the corpus of animal and human physiology and the art of surgery. He was one of the first to use ligatures in his experiments on animals. Galen is also known as "The king of the catgut suture"

China

In China, instruments resembling surgical tools have also been found in the archaeological sites of Bronze Age dating from the Shang Dynasty, along with seeds likely used for herbalism.

Hua Tuo

Woodblock printing by Utagawa Kuniyoshi of Hua Tuo

Hua Tuo (140–208) was a famous Chinese physician during the Eastern Han and Three Kingdoms era. He was the first person to perform surgery with the aid of anesthesia, some 1600 years before the practice was adopted by Europeans.Bian Que (Pien Ch'iao) was a "miracle doctor" described by the Chinese historian Sima Qian in his Shiji who was credited with many skills. Another book, Liezi (Lieh Tzu) describes that Bian Que conducted a two way exchange of hearts between people. This account also credited Bian Que with using general anaesthesia which would place it far before Hua Tuo, but the source in Liezi is questioned and the author may have been compiling stories from other works. Nonetheless, it establishes the concept of heart transplantation back to around 300 CE.

Middle Ages

Paul of Aegina's (c. 625 – c. 690 AD) Pragmateia or Compendiem was highly influential. Abulcasis Al-Zahrawi of the Islamic Golden Age later repeated the material, largely verbatim.

Hunayn ibn Ishaq (809–873) was an Arab Nestorian Christian physician who translated many Greek medical and scientific texts, including those of Galen, writing the first systematic treatment of ophthalmology. Egypt-born Jewish physician Isaac Israeli ben Solomon (832–892) also left many medical works written in Arabic that were translated and adopted by European universities in the early 13th century.

The Persian physician Muhammad ibn Zakariya al-Razi (c. 865–925) advanced experimental medicine, pioneering ophthalmology and founding pediatrics. The Persian physician Ali ibn Abbas al-Majusi (d. 994) worked at the Al-Adudi Hospital in Baghdad, leaving The Complete Book of the Medical Art, which stressed the need for medical ethics and discussed the anatomy and physiology of the human brain. Persian physician Avicenna (980–1037) wrote The Canon of Medicine, a synthesis of Greek and Arab medicine that dominated European medicine until the mid-17th century.

In the 9th century the Medical School of Salerno in southwest Italy was founded, making use of Arabic texts and flourishing through the 13th century.

Abulcasis (936–1013) (Abu al-Qasim Khalaf ibn al-Abbas Al-Zahrawi) was an Andalusian-Arab physician and scientist who practised in the Zahra suburb of Cordoba. He is considered to be the greatest medieval surgeon, though he added little to Greek surgical practices. His works on surgery were highly influential.

African-born Italian Benedictine monk (Muslim convert) Constantine the African (died 1099) of Monte Cassino translated many Arabic medical works into Latin.

Spanish Muslim physician Avenzoar (1094–1162) performed the first tracheotomy on a goat, writing Book of Simplification on Therapeutics and Diet, which became popular in Europe. Spanish Muslim physician Averroes (1126–1198) was the first to explain the function of the retina and to recognize acquired immunity with smallpox.

Universities such as Montpellier, Padua and Bologna were particularly renowned.

In the late 12th century Rogerius Salernitanus composed his Chirurgia, laying the foundation for modern Western surgical manuals. Roland of Parma and Surgery of the Four Masters were responsible for spreading Roger's work to Italy, France, and England. Roger seems to have been influenced more by the 6th-century Aëtius and Alexander of Tralles, and the 7th-century Paul of Aegina, than by the Arabs. Hugh of Lucca (1150−1257) founded the Bologna School and rejected the theory of "laudable pus".

In the 13th century in Europe skilled town craftsmen called barber-surgeons performed amputations and set broken bones while suffering lower status than university educated doctors. By 1308 the Worshipful Company of Barbers in London was flourishing. With little or no formal training, they generally had a bad reputation that was not to improve until the development of academic surgery as a specialty of medicine rather than an accessory field in the 18th-century Age of Enlightenment.

Guy de Chauliac (1298–1368) was one of the most eminent surgeons of the Middle Ages. His Chirurgia Magna or Great Surgery (1363) was a standard text for surgeons until well into the seventeenth century."

Early modern Europe

Wilhelm Fabry (1540–1634), father of German surgery

There were some important advances to the art of surgery during this period. Andreas Vesalius (1514–1564), professor of anatomy at the University of Padua was a pivotal figure in the Renaissance transition from classical medicine and anatomy based on the works of Galen, to an empirical approach of 'hands-on' dissection. His anatomic treatise De humani corporis fabrica exposed many anatomical errors in Galen and advocated that all surgeons should train by engaging in practical dissections themselves.

The second figure of importance in this era was Ambroise Paré (sometimes spelled "Ambrose" (c. 1510 – 1590)), a French army surgeon from the 1530s until his death in 1590. The practice for cauterizing gunshot wounds on the battlefield had been to use boiling oil, an extremely dangerous and painful procedure. Paré began to employ a less irritating emollient, made of egg yolk, rose oil and turpentine. He also described more efficient techniques for the effective ligation of the blood vessels during an amputation. In the same century, Eleno de Céspedes became perhaps the first female surgeon in Spain, and perhaps in Europe.

Another important early figure was German surgeon Wilhelm Fabry (1540–1634), "the Father of German Surgery", who was the first to recommend amputation above the gangrenous area, and to describe a windlass (twisting stick) tourniquet. His Swiss wife and assistant Marie Colinet (1560–1640 improved the techniques for Caesarean Section, introducing the use of heat for dilating and stimulating the uterus during labor. In 1624 she became the first to use a magnet to remove metal from a patient's eye, although he received the credit.

Modern surgery

Scientific surgery

The discipline of surgery was put on a sound, scientific footing during the Age of Enlightenment in Europe (1715–89). An important figure in this regard was the Scottish surgical scientist (in London) John Hunter (1728–1793), generally regarded as the father of modern scientific surgery. He brought an empirical and experimental approach to the science and was renowned around Europe for the quality of his research and his written works. Hunter reconstructed surgical knowledge from scratch; refusing to rely on the testimonies of others he conducted his own surgical experiments to determine the truth of the matter. To aid comparative analysis, he built up a collection of over 13,000 specimens of separate organ systems, from the simplest plants and animals to humans.

Hunter greatly advanced knowledge of venereal disease and introduced many new techniques of surgery, including new methods for repairing damage to the Achilles tendon and a more effective method for applying ligature of the arteries in case of an aneurysm. He was also one of the first to understand the importance of pathology, the danger of the spread of infection and how the problem of inflammation of the wound, bone lesions and even tuberculosis often undid any benefit that was gained from the intervention. He consequently adopted the position that all surgical procedures should be used only as a last resort.

Hunter's student Benjamin Bell (1749–1806) became the first scientific surgeon in Scotland, advocating the routine use of opium in post-operative recovery, and counseling surgeons to "save skin" to speed healing; his great-grandson Joseph Bell (1837–1911) became the inspiration for Arthur Conan Doyle's literary hero Sherlock Holmes.

Other important 18th- and early 19th-century surgeons included Percival Pott (1714–1788), who first described tuberculosis of the spine and first demonstrated that a cancer may be caused by an environmental carcinogen after he noticed a connection between chimney sweep's exposure to soot and their high incidence of scrotal cancer. Astley Paston Cooper (1768–1841) first performed a successful ligation of the abdominal aorta. James Syme (1799–1870) pioneered the Symes Amputation for the ankle joint and successfully carried out the first hip disarticulation. Dutch surgeon Antonius Mathijsen invented the Plaster of Paris cast in 1851.

Anesthesia

John Snow (1813–1858)

Modern pain control through anesthesia was discovered in the mid-19th century. Before the advent of anesthesia, surgery was a traumatically painful procedure and surgeons were encouraged to be as swift as possible to minimize patient suffering. This also meant that operations were largely restricted to amputations and external growth removals.

Beginning in the 1840s, surgery began to change dramatically in character with the discovery of effective and practical anaesthetic chemicals such as ether, first used by the American surgeon Crawford Long (1815–1878), and chloroform, discovered by James Young Simpson (1811–1870) and later pioneered in England by John Snow (1813–1858), physician to Queen Victoria, who in 1853 administered chloroform to her during childbirth, and in 1854 disproved the miasma theory of contagion by tracing a cholera outbreak in London to an infected water pump. In addition to relieving patient suffering, anaesthesia allowed more intricate operations in the internal regions of the human body. In addition, the discovery of muscle relaxants such as curare allowed for safer applications. American surgeon J. Marion Sims (1813–83) received credit for helping found Gynecology, but later was criticized for failing to use anesthesia on enslaved Black test subjects.

Antiseptic surgery

The introduction of anesthetics encouraged more surgery, which inadvertently caused more dangerous patient post-operative infections. The concept of infection was unknown until relatively modern times. The first progress in combating infection was made in 1847 by the Hungarian doctor Ignaz Semmelweis who noticed that medical students fresh from the dissecting room were causing excess maternal death compared to midwives. Semmelweis, despite ridicule and opposition, introduced compulsory handwashing for everyone entering the maternal wards and was rewarded with a plunge in maternal and fetal deaths, however the Royal Society dismissed his advice.

Until the pioneering work of British surgeon Joseph Lister in the 1860s, most medical men believed that chemical damage from exposures to bad air (see "miasma") was responsible for infections in wounds, and facilities for washing hands or a patient's wounds were not available. Lister became aware of the work of French chemist Louis Pasteur, who showed that rotting and fermentation could occur under anaerobic conditions if micro-organisms were present. Pasteur suggested three methods to eliminate the micro-organisms responsible for gangrene: filtration, exposure to heat, or exposure to chemical solutions. Lister confirmed Pasteur's conclusions with his own experiments and decided to use his findings to develop antiseptic techniques for wounds. As the first two methods suggested by Pasteur were inappropriate for the treatment of human tissue, Lister experimented with the third, spraying carbolic acid on his instruments. He found that this remarkably reduced the incidence of gangrene and he published his results in The Lancet.  Later, on 9 August 1867, he read a paper before the British Medical Association in Dublin, on the Antiseptic Principle of the Practice of Surgery, which was reprinted in the British Medical Journal. His work was groundbreaking and laid the foundations for a rapid advance in infection control that saw modern antiseptic operating theatres widely used within 50 years.

Lister continued to develop improved methods of antisepsis and asepsis when he realised that infection could be better avoided by preventing bacteria from getting into wounds in the first place. This led to the rise of sterile surgery. Lister instructed surgeons under his responsibility to wear clean gloves and wash their hands in 5% carbolic solution before and after operations, and had surgical instruments washed in the same solution. He also introduced the steam steriliser to sterilize equipment. His discoveries paved the way for a dramatic expansion to the capabilities of the surgeon; for his contributions he is often regarded as the father of modern surgery. These three crucial advances - the adoption of a scientific methodology toward surgical operations, the use of anaesthetic and the introduction of sterilised equipment - laid the groundwork for the modern invasive surgical techniques of today.

In the late 19th century William Stewart Halstead (1852–1922) laid out basic surgical principles for asepsis known as Halsteads principles. Halsted also introduced the latex medical glove. After one of his nurses suffered skin damage due to having to sterilize her hands with carbolic acid, Halsted had a rubber glove that could be dipped in carbolic acid designed.

X-rays

Wilhelm Roentgen (1845–1925)

The use of X-rays as an important medical diagnostic tool began with their discovery in 1895 by German physicist Wilhelm Röntgen. He noticed that these rays could penetrate the skin, allowing the skeletal structure to be captured on a specially treated photographic plate.

Modern technologies

In the past century, a number of technologies have had a significant impact on surgical practice. These include Electrosurgery in the early 20th century, practical Endoscopy beginning in the 1960s, and Laser surgery, Computer-assisted surgery and Robotic surgery, developed in the 1980s.
