History of surgery

Surgery (cheirourgia, from the Greek "cheir" meaning "hand" + "ergon" meaning "work") 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 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.

The first surgical techniques were developed to treat injuries and traumas. A combination of archaeological and anthropological studies offer insight into man's early 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 seem 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 ate around the edges of the wound and then twisted the insects' neck, leaving their heads rigidly attached like staples.

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.
