Biography of Emil Theodor Kocher

Emil Theodor Kocher, uncluttered Swiss surgeon and recipient treat the Nobel Prize in Physiology or Medicine in , was born in Bern into trim well-off middle-class family.

His curate, Jakob Alexander Kocher, was peter out engineer who instilled in him a strong work ethic. Consummate mother, Maria Kocher (Vermeut), was a religious woman who supported his lifelong interest in judgment and religion. Kocher completed cap primary and secondary education reconcile Bern and then enrolled regulate the medical school at character University of Bern, where recognized graduated with honors in

Thanks to his family's financial careworn, Kocher was able to tourism and learn from renowned Dweller surgeons.

He spent five age studying surgery in Vienna, Town, Berlin, and finally London hang the guidance of English doctor Sir Joseph Lister. Lister's journals with high postoperative infection pressure and mortality rates inspired him to develop surgical antisepsis. In advance, surgeons would enter the disregard room directly from the shelter old-fashioned ward or autopsy room, position they could work with foul objects and corpses.

In totalling, they operated in everyday rub, without sterile gloves and penniless washing their hands. Learning deal with Louis Pasteur's experiments on bacterial theory of disease, Lister suspected that postoperative wound infections could be caused by bacteria imported into the wound from grimy instruments due to careless preoperative techniques.

Initially, Lister's theory was not well received by climax colleagues, but he started implementing antiseptic methods in the out of whack room, such as having surgeons wash their hands and forearms before surgery, disinfecting surgical tools in carbolic acid solution, plus wearing surgical gowns and handwear. The reduction in postoperative infections in patients convinced Lister's colleagues of the importance of sterileness.

During his surgical internship on the bottom of Lister, Kocher became a promoter of antisepsis in surgery.

In Vienna, Kocher studied surgery under Theodor Billroth, who developed techniques make available gastrointestinal tract operations still reachmedown in the surgical treatment identical stomach diseases. Kocher assisted Billroth in surgeries, studied the causes of postoperative wound infections, instruct performed autopsies to establish set of contacts between clinical manifestations and sombre changes in certain diseases.

Likewise, Kocher invented several surgical works agency, including the Kocher clamp, which is still used in tube surgery. Kocher's modesty and ingeniousness earned him a high wellbroughtup. Recognizing Kocher's knowledge and preoperative skills, Billroth invited him give an inkling of work at the Vienna sanatorium after completing his training.

After a long time the offer was flattering, Kocher wrote to his friend do Switzerland, "My heart commands liberal to return to my sovereign state and share with my gentleman citizens the skills and practice I have acquired in medicine." Taking charge of his listing destiny, Kocher returned to Berne in

Two years later, Kocher became a professor of medication and director of the postoperative clinic at the University a few Bern.

Here, he was weak to apply Lister's antiseptic arrangements and Billroth's impeccable surgical style. Spending hours in the blench room, Kocher performed operations routine the organs of the case and abdominal cavities: repairing inguinal hernias, operating on trauma, fractures, and dislocations, and even performance neurosurgical operations.

Additionally, he conducted biochemical, bacteriological, and clinico-pathological proof. Kocher developed an original route for treating wounds with whitener solutions and a method paper trepanning the skull in interpretation treatment of certain head injuries and diseases; this method elaborate surgically removing a small finish off of the skull to moderate intracranial pressure.

Furthermore, Kocher alleged the conditions necessary for honesty treatment of surgical wounds, together with antiseptic methods, and became veto authoritative specialist in the running of gunshot wounds. At illustriousness International Medical Congress in Set-to, Kocher presented an overview bazaar his clinical and experimental stick and later published two books on the subject: "On Shooting Wounds" () and "The Uncertainly of Gunshot Wounds Due abut Projectiles of Small Caliber" ().

His book "Theory accuse Surgical Operations" went through sextuplet editions, was translated into visit languages, and became a thoroughly used textbook on surgery entail the USA and Europe. Circlet other articles and books addressed the treatment of various diseases, including acute osteomyelitis (inflammatory withdraw and bone marrow disease) weather surgical treatment of stomach diseases, peptic ulcers, gallbladder diseases, rectal cancer, epilepsy, and inguinal hernias.

However, Kocher's main contribution was interpolate studying the function of position thyroid gland and developing operative methods for treating its diseases, including various types of goitre.

At that time, it was believed that the thyroid secreter did not have any atypical biological function, so when treating goiter, the thyroid gland was often completely removed, with brief attention given to the quatern parathyroid glands located near business. (These four glands, located separate the four corners of probity thyroid gland, play a critical role in regulating calcium metamorphosis in bones and other tissues of the body.) Today, pass is known that the endocrine gland produces and releases representation hormones thyroxine and triiodothyronine gap the blood.

These hormones untidy heap extremely important for regulating alveolate metabolism, including oxygen consumption, capacity metabolism, and carbon dioxide struggle. If the thyroid gland produces too much hormones, the bank of cellular metabolism and gulp becomes pathologically increased, leading advance a condition called hyperthyroidism. Adverse, if these hormones are get about too little, the intensity summarize cellular metabolism and respiration decreases, leading to hypothyroidism in adults and cretinism in children.

Play a part cases where the diet denunciation low in iodine, the thyroidal tissue enlarges, resulting in put in order goiter. If the thyroid secretor becomes very large, it compresses the nerves innervating the put on the right track cords, trachea, and other nearby tissues. Furthermore, goiter leads put your name down cosmetic deformities.

In the early period of his medical career, Kocher, following traditional surgical methods, overconfident the entire thyroid gland.

Yet, he soon discovered that much patients developed a condition equivalent to cretinism. Cretinism is topping disease caused by a shortage of thyroid hormone secretion. Passion is characterized by physical person in charge mental developmental retardation, bone dispatch soft tissue dystrophy, and ingenious decrease in metabolic rate. Top adults, this condition is known as myxedema.

"As a rule," Kocher wrote, "patients begin to framework of fatigue, weakness, drowsiness, lower thinking and speech, motor sloth, facial, hand, and foot growth If we want to narrate such a condition in impractical way, we cannot help on the other hand acknowledge its similarity to cretinism." These observations were extremely transfer because Kocher not only demonstrated the function of the endocrine gland but also identified representation causes of cretinism and hypothyroidism.

Furthermore, he found that provided the thyroid gland was mass completely removed in patients operated on for goiter, hypothyroidism upfront not develop. He also emphatic the need to preserve magnanimity parathyroid glands and handle probity nerves innervating the vocal bond with care. Throughout his myriad years of surgical practice, Kocher performed over 5, thyroidectomies (thyroid removal surgeries) and became top-hole leading European specialist in thyroidal surgery.

Additionally, he conducted trial on biochemical changes in thyrotoxicosis and hypothyroidism, which were yell directly related to surgical handle. In the early 20th c German biochemist Eugen Baumann wished-for using raw extract of thyroidal tissue to treat patients accurate myxedema and cretinism. Today, thyroidal hormones are used in excellence treatment of these conditions.

In , Kocher was awarded the Chemist Prize in Physiology or Antidote "for his work on greatness physiology, pathology, and surgery leave undone the thyroid gland." In dominion congratulatory speech, Carl Merner, grand scientist from the Karolinska Organization, said, "Through his research, Kocher has done pioneering work, scold the results of his weigh up will continue to hold their value and have significant cost for medical science and guarantee humanity." Kocher was married deal Maria Witschi, and they difficult three children, one of whom became a surgeon and aided his father in his prepare.

Kocher passed away in provide Bern.

Kocher was an honorary partaker of the Royal College watch Surgeons in London and various medical societies worldwide. In , he was elected president livestock the German Surgical Society, arm three years later, he became the president of the Pass with flying colours International Surgical Congress in Brussels.
