Surgeon

In medicine, a surgeon is a medical doctor who performs surgery. Even though there are different traditions in different times and places, a modern surgeon is a licensed physician and received the same medical training as physicians before specializing in surgery.
In some countries and jurisdictions, the title of 'surgeon' is restricted to maintain the integrity of the craft group in the medical profession. A specialist regarded as a legally recognized surgeon includes podiatry, dentistry, and veterinary medicine. It is estimated that surgeons perform over 300 million surgical procedures globally each year.
The first person to document a surgery was the 6th century BC Indian physician-surgeon, Sushruta. He specialized in cosmetic plastic surgery and even documented an open rhinoplasty procedure. His magnum opus Suśruta-saṃhitā is one of the most important surviving ancient treatises on medicine and is considered a foundational text of both Ayurveda and surgery. The treatise addresses all aspects of general medicine, but the translator G. D. Singhal dubbed Sushruta "the father of surgical intervention" on account of the extraordinarily accurate and detailed accounts of surgery to be found in the work.
After the eventual decline of the Sushruta School of Medicine in India, surgery was largely ignored until the Islamic Golden Age surgeon Al-Zahrawi (936–1013) re-established surgery as an effective medical practice. He is considered the greatest medieval surgeon to have appeared from the Islamic World, and has also been described as the father of surgery. His greatest contribution to medicine is the Kitab al-Tasrif, a thirty-volume encyclopedia of medical practices. He was the first physician to describe an ectopic pregnancy, and the first physician to identify the hereditary nature of haemophilia.
His pioneering contributions to the field of surgical procedures and instruments had an enormous impact on surgery but it was not until the 18th century that surgery emerged as a distinct medical discipline in England.
In Europe, surgery was mostly associated with barber-surgeons who also used their hair-cutting tools to undertake surgical procedures, often at the battlefield and also for their employers. With advances in medicine and physiology, the professions of barbers and surgeons diverged; by the 19th century barber-surgeons had virtually disappeared, and surgeons were almost invariably qualified doctors who had specialized in surgery. Surgeon continued, however, to be used as the title for military medical officers until the end of the 19th century, and the title of Surgeon General continues to exist for both senior military medical officers and senior government public health officers.
In 1950, the Royal College of Surgeons of England (RCS) in London began to offer surgeons a formal status via RCS membership. The title Mister became a badge of honour, and today, in many Commonwealth countries, a qualified doctor who, after at least four years' training, obtains a surgical qualification (formerly Fellow of the Royal College of Surgeons, but now also Member of the Royal College of Surgeons or a number of other diplomas) is given the honour of being allowed to revert to calling themselves Mr, Miss, Mrs or Ms in the course of their professional practice, but this time the meaning is different. It is sometimes assumed that the change of title implies consultant status (and some mistakenly think non-surgical consultants are Mr too), but the length of postgraduate medical training outside North America is such that a qualified surgeon may be years away from obtaining such a post: many doctors previously obtained these qualifications in the senior house officer grade, and remained in that grade when they began sub-speciality training. The distinction of Mr (etc.) is also used by surgeons in the Republic of Ireland, some states of Australia, Barbados, New Zealand, South Africa, Zimbabwe, and some other Commonwealth countries. In August 2021, the Royal Australasian College of Surgeons announced that it was advocating for this practice to be phased out and began encouraging the use of the gender neutral title Dr or appropriate academic titles such as Professor.
The reason for the otherwise undistinguished title of "mister" is historical. In the 18th century only physicians, with an MD degree, were entitled to call themselves "doctor". Most surgeons did not have a degree—in the Middle Ages they were also barbers, expert users of cutting tools—and were considered inferior and subordinate to physicians; "Mr" was initially a lower honorific, but came to be a badge of honour.
In many English-speaking countries the military title of surgeon is applied to any medical practitioner, due to the historical evolution of the term. The US Army Medical Corps retains various surgeon United States military occupation codes in the ranks of officer pay grades, for military personnel dedicated to performing surgery on wounded soldiers.
Some physicians who are general practitioners or specialists in family medicine or emergency medicine may perform limited ranges of minor, common, or emergency surgery. Anesthesia often accompanies surgery, and anesthesiologists and nurse anesthetists may oversee this aspect of surgery. Surgeon's assistant, surgical nurses, surgical technologists are trained professionals who support surgeons.
In the United States, the Department of Labor description of a surgeon is "a physician who treats diseases, injuries, and deformities by invasive, minimally-invasive, or non-invasive surgical methods, such as using instruments, appliances, or by manual manipulation".
Around the world, the array of 'surgical' pathology that a surgeon manages does not always require surgical methods. For example, surgeons treat diverticulitis conservatively using antibiotics and bowel rest. In some cases of small bowel obstruction, particularly where a patient has had previous abdominal surgery, the surgeon treats the patient with fluid resuscitation, nasogastric decompression of the stomach, which gives rise to resolution of the intestinal obstruction in cases where adhesions are the aetiology of the obstruction. The same is true for other craft groups in surgery.
