History of Surgery
Prehistory
The first surgical procedures were performed in the
Neolithic Age (about 10,000 to 6000 bc). Trepanning, a procedure in which a hole
is drilled in the skull to relieve pressure on the brain, may have been
performed as early as 8000 B.C. In Egypt, carvings dating to 2500 B.C. describe
surgical circumcision—the removal of foreskin from the penis and the clitoris
from female genitalia. Operations such as castration (the removal of a male’s
testicles); lithotomy (the removal of stones from the bladder); and amputation
(the surgical removal of a limb or other body part) are also believed to have
been performed by the Egyptians. Ancient Egyptian medical texts have been found
that provide instructions for many surgical procedures including repairing a
broken bone and mending a serious wound. In ancient India, the Hindus surgically
treated bone fractures and removed bladder stones, tumours, and infected
tonsils. They are also credited with having developed plastic surgery as early
as 2000 B.C. in response to the punishment of cutting off a person’s nose or
ears for certain criminal offenses. Using skin flaps from the forehead, Hindu
surgeons shaped new noses and ears for the punished criminals. In the 4th
century B.C., the Greek physician Hippocrates published descriptions of various
surgical procedures, such as the treatment of fractures and skull injuries, with
directions for the proper placement of the surgeon’s hands during these
operations
.
Middle Ages
During most of the Middle Ages (5th century to 14th century
ad), the practice of surgery declined. It was viewed as inferior to medicine,
and its practice was left to barbers who travelled from town to town cutting
hair, removing tumours, pulling teeth, stitching wounds, and bloodletting, the
practice of draining blood from the body, then thought to cure illness. The
red-and-white striped pole that today identifies barbershops derived its design
from this practice. The red stripes symbolize blood and the white stripes
signify bandages.
In 1316 the French surgeon Guy de Chauliac published
Chirurgia magna (Great Surgery). This massive text describes how to remove
growths, repair hernias (protrusion of an organ through surrounding structures),
and treat fractures using slings and weights. The text helped surgery gain
respect as a serious science. At this time a new order of surgeons arose in
France. They were called surgeons of the long robe, distinguished from the
barber surgeons who were known as surgeons of the short robe. The barber
surgeons had little medical training, while the surgeons of the long robe were
studied physicians and considered such practices as bloodletting primitive.
Corporations, or guilds, of surgeons of the long robe were formed in several
countries.
Towards the Modern Era
During the 16th, 17th, and 18th centuries, many discoveries
in surgical practice took place. Much credit belongs to the French surgeon
Ambroise Paré, often called the father of modern surgery. Paré successfully
employed the method of ligating, or tying off, arteries to control bleeding,
thus eliminating the old method of cauterizing, or searing, the bleeding part
with a red-hot iron or boiling oil. Discoveries about functions of the human
body also helped make surgery a more accurate science during this period. For
example, the English physician and anatomist William Harvey discovered the
process of blood circulation and Italian anatomist Marcello Malpighi identified
the existence of tiny blood vessels called capillaries that carry blood from the
major blood vessels to the cells of the body. John Hunter, a British anatomist
and surgeon, stressed the close relationship between medicine and surgery and
performed many experimental operations that advanced the practice of surgery.
Most surgery, however, continued to be restricted to less
critical areas of the body or to operations that did not penetrate the skin too
deeply. Surgeons rarely opened the abdomen, chest, or skull because of the pain
it caused the patient and the risk of infection. This changed in 1846 when
anaesthesia was used as a way to mask pain during surgery by American dentist
William Morton. Although Morton is often credited with the discovery of surgical
anaesthesia, American surgeon Crawford W. Long used anaesthesia in 1842 during
the removal of tumours but did not publish his results until 1849.
Post-surgical infections remained a serious complication of
surgery until the mid-19th century when the French chemist Louis Pasteur
discovered that fermentation or putrefaction, the decay and death of body
tissue, is caused by bacteria in the air. In 1865 the British surgeon Joseph
Lister applied Pasteur’s work to surgery, developing antiseptic (germ-killing)
techniques including the use of a carbolic acid spray to kill germs in the
operating room before surgery. These antiseptic procedures helped eliminate
postoperative infection. Other physicians, including Austrian Ignaz Semmelweiss
and American Oliver Wendell Holmes, determined that bacteria are also carried on
the hands and clothing and transferred from patient to patient as a physician
attends one after another. These physicians pioneered techniques such as washing
hands and changing into clean clothing before surgery that prevent wounds from
being contaminated during surgery.
The Modern Era
In the late 1800s, having solved the problems of pain and
infection, surgeons began performing new types of surgery including procedures
on the abdomen, brain, and spinal cord. At the turn of the 20th century,
improved diagnostic abilities and methods of treatment helped surgery become
even more effective. When the German physicist Wilhelm Conrad Roentgen invented
X rays in 1895 to “photograph” the inside of the body he changed the way
surgery was performed. The discovery of the blood groups A, B, and O by Austrian
pathologist Karl Landsteiner enabled surgeons to give patients transfusions of
their own blood type to ensure survival during surgery. The need for a readily
available supply of blood for transfusions led to the creation of blood banks in
1937.
Other technological advances permitted surgeons to perform
increasingly complex and difficult operations. The introduction of antibiotics
in the 1940s further minimized the risk of postoperative infection. The
development of the heart-lung machine in 1953 by American surgeon John H. Gibbon
allowed surgeons to more easily and successfully perform surgery on these
organs. It also marked the beginning of modern clinical heart surgery. The
operating microscope, developed in the 1950s, provided surgeons with a way to
perform delicate operations on minute body structures like the inner ear and the
eye, and more recently, enabled surgeons to reattach the tiny blood vessels from
severed limbs to the body (see Microsurgery). The first kidney transplants were
performed in the 1950s, and the first heart transplant, in 1967, was performed
by South African physician Christiaan Barnard.
New techniques continue to advance the field of surgery.
High frequency sound waves, called ultrasound, are directed at kidney and
gallbladder stones to break them apart so that they can be eliminated through
the excretory system. Cryosurgery freezes and destroys abnormal tissue and is
used to treat haemorrhoids and some cervical disorders, and to remove certain
skin growths. Laser surgery, on the other hand, uses a beam of light to vaporize
or destroy tissue, a procedure commonly employed in ophthalmology, neurosurgery,
and thoracic surgery.
A variety of surgical procedures are performed using an
endoscope, an instrument that permits doctors to view the inside of the body
without making a large incision and through which special tools such as lasers
or knives can be inserted to operate on a particular area of the body. Surgery
using an endoscope, also called laparoscopy, is used to perform tubal ligation,
gall bladder removal, or lung removal. This technique is commonly used for
biopsies, in which tissue is removed from an organ for evaluation under a
microscope, or for removing patches of diseased tissue.
Transplantation surgery, in which organs or tissues are
removed from one person and surgically implanted into another person, is now
performed for the eye lens and cornea, blood, bones and bone marrow, heart,
lung, liver, and pancreas. In severe burn cases, healthy skin from an uninjured
site is transferred to an area that has been damaged. Patients typically receive
transplants when their own organs fail. Donor organs come from recently deceased
individuals who have indicated on organ donor cards a desire to donate organs or
whose family members have authorized donation of the deceased’s organs.
Donated organs must be transplanted within 24 to 48 hours after a donor’s
death.
Ambulatory, or same-day surgery, is performed in a
physician’s office or clinic. It involves operations that use minimally
invasive techniques, require less extensive cutting, and use anaesthesia that
clears rapidly from the body. Some types of plastic surgery, implantation of
permanent pacemakers, breast surgery, and biopsies are typically performed in
ambulatory surgical clinics.
