Cryosurgery is a medical procedure that destroys abnormal or diseased cells in the body at extremely low temperatures. The word cryosurgery comes from the Greek words 'cryo' (cold as ice) and 'surgery'. Cryosurgery has historically been used to treat a number of ailments, including a variety of dangerous skin problems. Around 2500 BC, Egyptians used cool temperatures to treat various skin lesions and inflammation.
The first cryosurgery was introduced in England in 1845, with James Arnott describing a method of using salt water frozen at minus 20 degrees Celsius. However, the treatment of skin began with the widespread application of cryosurgery in the early nineteenth century. Medical scientists in Chicago first introduced the use of carbon dioxide in cryosurgery, and since then the widespread use of carbon dioxide in cryosurgery has been observed.
The use of liquid oxygen in cryosurgery began in the 1920's. Dr. in 1950. Ray Ellington applied liquid nitrogen to cryosurgery. The path of modern cryosurgery begins with the hand of Dr. Irving Cooper. Cryosurgical treatment was later further improved by the use of other cryogenic agents such as nitrous oxide, carbon dioxide, argon, ethyl chloride and fluorinated hydrocarbons.
Cryosurgery works by taking advantage of the destructive energy at temperatures even lower than the temperature at which ice freezes. At low temperatures, the ice crystals inside the body cells can be removed by removing the special shape or arrangement. Cryosurgery is usually performed using a mixture of liquid nitrogen, carbon dioxide, snow, argon and a combination of dimethyl ether and propane. These liquid gases are called cryogenic agents. Some of these cause temperatures of -41°C.
Benefits of Cryosurgery
1. Cryosurgery is much more convenient than all other methods of treating cancer. It requires less cutting and tearing than actual or conventional surgery. Only tiny incisions are needed to insert the cryoprobe through the skin.
2. In surgery, pain, bleeding and other complications are minimized by cryosurgery.
3. It is less expensive than other treatments and takes less time to heal.
4. You have to stay in the hospital for a very short time. In many cases you do not have to stay in the hospital.
5. Cryosurgery can be performed with local anesthesia.
6. Physicians give cryosurgical treatment to a limited area of the body. As a result, they can protect nearby healthy cells from destruction.
7. This treatment can be safely repeated.
8. Cryosurgery is ideal for patients who are unable to cope with normal surgery due to their age and other physical reasons.
Disadvantages of cryosurgery
1. Uncertainty over the long-term and efficacy of cryosurgery treatment.
2. Although physicians can effectively use cryosurgery to detect tumors through imaging tests, it cannot prevent the spread of microscopic cancer.
3. As a side effect of cryosurgery abuse, the normal structure of the liver and lungs can be destroyed or nervous problems can arise.
4. Failure to determine the exact location of infected cells may result in the spread of the virus to other parts of the body using cryosurgery.
Pioneers of cryosurgery
Dr. Ray Elington: The first liquid nitrogen was used in cryosurgery. After the Second World War, he started treating various skin wounds by dipping a cotton ball in liquid nitrogen. His application of liquid nitrogen later made the use of liquid nitrogen popular for cryosurgery. Liquid nitrogen is currently used in all types of cryosurgery.
Dr. Irving Cupper (1922-1985): Full name is Dr. Irving S. Cooper. His contribution to the field of cryosurgery is widely acknowledged. Because he was the first to use a liquid nitrogen probe instead of a cotton ball. This special equipment opens the door to many new possibilities in cryosurgery. The cryoprobe currently used in cryosurgery is an evolution of the equipment used.
