Surgery traditionally refers to procedures (called surgery) that involve manually cutting or stitching body tissues to treat diseases, injuries or pathologies. But new advances in surgical technology make this concept more complex. In some cases, laser, radiation and other methods are used instead of a scalpel, and it is not necessary to stitch to close a wound.
In modern medicine, it is difficult to make a clear distinction between a surgical operation and a medical procedure (which usually does not involve cutting or suturing the body tissues). But it is not required: the main thing is that the doctor performing the procedure is experienced and well prepared.
Surgery is a broad field of medicine, which includes many different technologies. During some surgical procedures, tissues are removed, such as an abscess or a tumor. During others, blockages are removed. During third arteries and veins are brought to new areas to provide additional blood flow where there is not enough.
During a surgery called a transplant, a certain organ, such as a skin, kidney or liver, is removed from the person and then placed back in the same person (e.g., skin) or another person.
To replace the blood vessels or connective tissue may be implanted grafts, which in some cases are made of artificial materials, and to strengthen or replace damaged parts of the bone may be introduced metal rods.
Sometimes, surgery can confirm the expected diagnosis. Biopsy, which extracts a piece of tissue for examination under a microscope, is the most common type of diagnostic surgery. In some emergency cases, when there is no time for diagnostic tests, surgery is performed for both diagnosis and treatment simultaneously. For example, surgery may be required to quickly detect and repair organs that are bleeding as a result of an injury caused by a gunshot wound or car accident.
Categories of Surgical Interventions
In terms of urgency, surgical interventions are often divided into three categories: emergency operations; urgent ones; planned ones.
Emergency surgery, such as the purchase of intense internal bleeding, should be performed as soon as possible, because the bill goes on minutes.
In urgent surgical operations, such as removal of an inflamed appendix, the bill goes on the clock.
Scheduled surgical operations, such as knee replacement, can be postponed for a certain period of time and only after everything necessary to increase the patient’s chances of successful completion of surgery and subsequent recovery.
Cosmetic surgery is a planned surgical operation, the main purpose of which is to improve the appearance.
Cosmetic surgery involves many different operations. A person should choose a doctor who meets the standards in force in this field (professionally certified) and has extensive experience in performing such operations.
In order to achieve the best results after surgery, special instructions must be carefully followed, so cosmetic surgery is recommended only for people with a high level of motivation.
Despite the popularity and attractiveness of cosmetic surgery, such operations are not cheap and involve certain risks, including possible serious health consequences, as well as the possibility that the resulting appearance may be less attractive than before the operation.
