криотерапияCryotherapy, cryosurgery cryosurgery target destruction is a form of therapeutic procedures aimed at the destruction of diseased tissues, including cancer cells. Cryotherapy and cryosurgery, essentially interchangeable procedures, while the term «cryosurgery is used to denote cryotherapy, involving surgery.

During cryotherapy with liquid nitrogen or argon is conducted by a special applicator with thick needle (a cryoprobe), and the gas forms an extremely low temperature, destroying disease tissues. If the procedure requires internal location of a cryoprobe, specialist monitors its activities and movement with the help of visual devices, ultrasound, installations computed tomography or magnetic resonance.


Types of cryotherapy

Distinguish external, percutaneous and surgical cryotherapy. External procedures, as a rule, are applied in the treatment of skin disorders and eye lesions.

  • Warts and senile fibroids
  • Large freckles
  • Retinoblastoma (children’s cancer)
  • Prostate cancer, liver and cervical (cervical) zones, especially in those cases when surgical intervention is excluded

Cryotherapy is often used in the treatment of tumors of the kidneys, bone tumors (especially in the area of the spine), with lung cancer and breast cancer, benign tumors of the mammary glands (fibroadenoma). Scientists continue to investigate the efficacy of cryotherapy, trying to figure out how long could be provided by a cold effect, but already today the undisputed effectiveness of cryotherapy is proved by the example of many patients.


Preparation for cryotherapy

To eliminate the possible discomfort for half an hour before the procedures of external cryotherapy some experts advise their patients to take the ibuprofen (400mg), with a small dose of antibiotics helps to avoid infectious contamination.

Advantages and disadvantages of cryotherapy


  • The period of recovery for patients with a tumor of the kidney or liver with cryotherapy with open surgical intervention is much shorter than with open surgical removal of the tumor.
  • Cryotherapy less painful compared with radiofrequency ablation or treatment of the affected areas of high-temperature methods.
  • Percutaneous cryotherapy less traumatic than open surgery, as for the introduction of a cryoprobe under the skin rather small incision, which in turn significantly reduces the risk of damage to healthy tissue.
  • After treatment fibroadenoma cryotherapy does not cause excessive hardening of tissues and leaves virtually invisible scar.


The risks and side effects

As with any procedure involving percutaneous penetration, with cryotherapy may bleeding.

In the procedure, cryotherapy, there is a risk of damage to healthy tissue, such as the processing of the liver, the possible risk of injury to the bile duct, in the treatment of kidney, ureter, when prostate cryotherapy may be damaged rectum.

Sometimes cryotherapy, which is in close proximity to the lungs or the diaphragm may cause lung collapse, or the accumulation of liquid in okololegochnykh area.
