Laser surgery uses a laser light source (laser beam) to remove diseased tissue or treat blood vessels. Alternatively, the laser is used for cosmetic purposes; It can remove wrinkles, moles or tattoos.
There are a number of different types of lasers, each of which has a different use and specifications. Three types of laser are used in laser surgery centers: carbon dioxide (CO2); YAG laser; and pulse.
Laser surgery goals
Laser surgery is used for:
- cutting out or destroying diseased tissue without harming healthy,
- reduce or destroy tumors and lesions,
- closing nerve endings in order to reduce postoperative pain,
- cauterization (compaction) of blood vessels to reduce blood loss,
- sealing the lymphatic vessels to minimize edema,
- removal of moles, warts, tattoos,
- reduce the appearance of wrinkles on the skin.
Some types of laser surgery should not be performed on pregnant women, people with severe heart disease, heart disease, or other serious health problems.
In addition, since some surgical laser procedures are performed under general anesthesia, the risks of the operation should be fully discussed with the anesthesiologist.
Laser surgery: description
The laser can be used to perform almost any surgical procedure. Laser surgery clinics use a variety of laser systems that can cut, coagulate, vaporize, and remove tissue. Most laser surgery centers use original laser devices for performing both standard and non-standard procedures. Using a laser, an experienced and trained surgeon can perform various tasks, significantly reducing blood loss, postoperative patient discomfort, the likelihood of wound infection, the spread of certain types of cancer, minimizing the degree of surgery (in some cases).
Lasers are extremely useful in open and laparoscopic operations. Common surgical laser applications include breast surgery, gallbladder removal, bowel resection, hemorrhoidectomy, and many others.
Laser surgery is often a standard procedure for professionals in the field of:
Regular laser use is practiced for:
- eliminate moles,
- removal of benign, precancerous or cancerous tissues or tumors,
- tonsil remover,
- hair removal or transplant.
Lasers are also used to treat:
- angina pectoris,
- cancerous or benign tumors,
- gum diseases and teeth
- ectopic pregnancy
- from mild to moderate myopia and astigmatism,
- prostate gland
- ovarian cysts,
- varicose veins
- other diseases and disorders.
Benefits of Laser Surgery
Often referred to as “bloodless surgery,” laser procedures usually produce less bleeding than normal surgery. The heat generated by the laser reduces the risk of infection. Because a smaller incision is required, laser procedures often take less time than traditional operations. Sealing blood vessels and nerves reduces bleeding, swelling, scarring, pain, and the duration of the recovery period.
Diagnostics and training
Since laser surgery is used to treat a wide variety of conditions, the patient must receive detailed instructions from the doctor on how to prepare for a particular procedure.
Most laser surgeries can be performed on an outpatient basis, and patients are usually allowed to leave the hospital or medical office when their vital signs have stabilized.
The doctor may prescribe an analgesic (pain reliever) after surgery. The amount of time required for recovery after surgery depends on the complexity of the operation and the individual characteristics of the patient.
Laser surgery: risks
Laser surgery may include risks that are not associated with traditional surgical procedures. The laser beam, combined with sufficiently high energy and absorption, can ignite clothing, paper and hair. The risk of fire from a laser increases in the presence of oxygen. It is also important to protect against electrical shock, as lasers require high voltage.
The laser beam can affect healthy tissue, in which case it causes injuries that are painful. Errors or inaccuracies in laser surgery can lead to a deterioration in the patient’s vision or leave scars on the skin.
All risks, precautions and possible complications of the patient should be discussed by a doctor.
