Cancer after cryodestruction

.
.

Cryodestruction is a technique for removing benign and malignant neoplasms by deep freezing of the affected body part. Cryogenic melting of tissues is achieved by contact. To achieve a therapeutic effect on the surface of the applicator, which is selected depending on the size of the tumor, nitrous oxide is fed. This causes a local decrease in temperature.

The method of therapy with ultralow temperatures has become most widespread in the treatment of malignant neoplasms of the skin and cervix.

Benefits of cryodestruction in skin cancer

Cancer of the skin in the form of basal cell carcinoma is recommended to be treated with cryodestruction. In such cases, this therapy has several advantages:

  1. Positive cosmetology result of treatment.
  2. The possibility of treating malignant neoplasms of virtually any localization and diameter.
  3. Operative treatment is carried out on an outpatient basis, that is, to a patientafter cryodestructionno hospitalization is required.
  4. Cryosurgery is performed under local anesthesia, which excludes the risks of complications of general anesthesia.
  5. Cryosurgical therapy is allowed for pregnant and elderly patients.
  6. The use of ultra-low temperatures does not provoke postoperative bleeding.

Care of the wound after cryodestruction

Immediately before manipulation, the doctor takes a biopsy specimen from the affected area of ​​the body. A tumor biopsy is necessary for the final confirmation of an oncological diagnosis.

The procedure of cryopreservation is considered a painless intervention. Therefore, the surgeon uses "Ketanol" for premedication, and the operating field is treated with a 2% solution of "Lidocaine." In modern oncological practice, doctors use such variants of cryodestruction:

  1. Spray with liquid nitrogen. In this case, very often the cooling liquid spreads around the treated area.
  2. Metal applicator. This technique has the highest accuracy due to the addition of nitrous oxide to the metal of the working surface.

The duration of the standard procedure of basal cell cryosurgery is about 30 minutes, which is quite enough for a complete excision of the tumor.

In the first hours after a cold intervention around the operating field, you can notice bright red rashes. The next day in this area formed a traumatic edema, smoothly turning into a wet wound. During this period, the postoperative zone should be treated with weak solutions of antiseptics (manganese and sintomycin). In the following this procedure is carried out with the help of anti-allergenic soap (child or household).

Within 10-14 days at the site of cryosurgical intervention, a scab is formed.

Side effects of cryodestruction

The most common complication of cold therapy is progressive swelling. The volume of edematous tissue depends on the diameter of the malignant neoplasm. This side effect, as a rule, disappears in two weeks. Swelling of the soft tissues, especially in the face, can cause cosmetic discomfort to the patient.

Another complication of cryodestruction is the pallor of the skin, which in some cancers can remain for life. Such changes are accompanied by a violation of the surface sensitivity of the skin. In most cases, tactile sensations are restored after 2-3 months and do not require special medication.

Cryosurgical removal of mutated tissues results in scar formation. Experts point out the absence of scar changes of the skin in the presence of tumors with a diameter of up to one centimeter.

Contraindications for cryodestruction

The cryodestruction procedure is not recommended for patients with intolerance to low temperatures. Also, special attention is required by cancer patients who have allergic reactions to local anesthetics. For this category of patients, an allergological test is performed before the manipulation.

Cryodestruction in gynecological practice

Recently, a significant modernization of cryosurgical equipment has taken place in gynecology, which has greatly expanded the scope of application of ultra-low temperatures. The installation for the generation of cryopreservation in conjunction with a colposcope allows to influence not only the malignant neoplasm, but also to fight some precancerous conditions.

The procedure is performed on an outpatient basis without general and local anesthesia.

Cryodestruction of the cervix

Initially, a gynecologist with the help of a colposcope determines the exact location of the tumor. After this, in the mutation zone, a local temperature decrease of -198 ° C is caused for three minutes. This procedure is repeated one more time, which forms a limited tumor necrosis. The degree of destruction of the tumor after cryodestruction of the cervix depends on the depth of freezing.

Serous discharge after cryodestruction, as a rule, is observed in the first two weeks. After such therapy, the most serious complication is a relapse of cancer, which, according to most specialists, can be cured by repeated cryosurgery.

According to statistical data, the frequency of recurrent mutation of the mucous membrane of the cervix in this treatment does not exceed 14%. It should be noted that the best results of cold therapy are observed in the initial phases of the oncological disease. At the same time, deep frost is not recommended for patients in stages 3-4 of malignant growth.

Cancer after cryodestructionshould be monitored through periodic preventive examinations, which should be conducted at least twice a year.
