Description

FIELD OF THE INVENTION The invention relates to medicine, namely cryosurgery.

Methods for removing tumors by clipping with a scalpel or ultrasound knife are known. ClIO However, these methods are painful and require anesthesia; in addition, bleeding from dissected tissues is possible, as well as dissemination of tumor cells: during wound healing, coarse, deforming organs and tissues, scars are formed.

A method of cryosurgical treatment is also known, which consists in cryodestruction and removal of pathological tissues. 2

However, the known method is not sufficiently effective, since the subsequent regeneration of tissues proceeds, respectively, as such after the surgical removal of formations,. with possible scars. This is due to the fact that the cut-off of tissues is beyond the possible demarcation line of the subsequent cryonecrosis, and bleeding is also possible.

The aim of the invention is to ensure tissue regeneration without coarse scars and reduction of necrobiosis products.

This goal is achieved by the fact that, according to the method of cryosurgical treatment, which involves cryodestruction and removal of pathological tissues, before removing the pathological tissues, they are subjected to freezing with the seizure of healthy tissue 3-4 mm away from the formation, after which the formation is removed.

The method is carried out as follows.

Standard preparatory, characteristic

15 for the place of operation. Pathological formation is frozen in such a way that cm, so that healthy 1 tissues, the surrounding formation, are frozen 3-4 mm to the sides. At the same time, the excision of pathologically altered tissues within the formation boundary is made.

Example 1. Ill B., 35 years old, for 8 years suffering from an atypical transformation zone, eroded ectropion, deformity and old cervical ruptures. It was treated conservatively, namely with sea buckthorn oil swabs, aloe, sprin with chamomile and oak bark tincture. Diather mocoagulation of ectopia was performed twice. The treatment was carried out as follows. The patient was placed in a gynecological chair, the external genital organs and vagina were treated with iodonate. The cervix was exposed in the mirrors. An autonomous cryosurgical apparatus was inserted into the cervical canal to a depth of 8 mm, and parallel to the depth of frost penetration was controlled by thermocouples. Cryo-aerosol was performed until the area was measured to cover the ectropion by 4 mm around the perimeter. Electric heating was turned on and the cryoapparatus was removed for 30 seconds. Then, the cervix was electrocuted by means of a diathermoconizer. Frozen tissue was excised along the edge of the ectropion. No bleeding was observed. The patient was under control for 0.5 years. No recurrence of the disease, stenosis of the cervical canal, or scar tissue of the cervix uteri. Thus, the excision of the pathological formation is carried out through a conglomerate of frozen tissue, which excludes the possibility of dissemination of tumor cells, bleeding during surgery, and painful manipulation. These results are due to the fact that there is no blood circulation in frozen tissues and the nerve endings are in a state of scientific research institute of cold blockade. The fifiK operation requires only, for example, ultrasound, electrocautery, which is capable of dissecting frozen tissue. After excision of the formation, the surrounding healthy tissue remains frozen 4-5 mm in contour in depth. Due to the fact that the zone of necrosis is always smaller than the zone of freezing and the surface of the zone of necrosis is located 3 mm closer to the surface of the tissue than that of the freezing zone, healthy tissues undergo minimal trauma. As a result of surface exposure, the regeneration proceeds with minimal formation of necrotic tissues. The experimental and clinical tests performed in the described method showed that it is bloodless, painless, eliminates the possibility of dissemination of tumor cells and bleeding during surgery and after it, subsequent rega - tissue irradiation passes without the formation of coarse scars. The invention of the method of cryosurgical treatment, which consists in cryodestruction and removal of pathological tissues, characterized in that, in order to ensure tissue regeneration without coarse scars and reduction of necrobiosis products, before removing pathological tissues, they are subjected to freezing 3-4 mm to healthy tissue. from the formation, after which the formation is removed.
