VI KOCHENOV'S CYST CRYOSURGERY TECHNIQUE

FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, namely to cryosurgery and can be applied for cryosurgical management of various cysts. Substance of the technique consists in the fact that cysts 2 mm in diameter with the contents translucent through skin or mucosa require cryocompression destruction by multiple freezing and thawing with covering a folded pathological tissue to be frozen from the outside by cryoaccumulators passively cooled in liquid nitrogen. At the stage of spontaneous thawing through a frozen tissue, a pointed cryoinstrument cooled in liquid nitrogen is used to perforate a cyst cavity to evacuated by cryocompression thawing and greater approaching of the cryoaccumulators than that one observed during previous freezing. The cysts up to 4 mm in diameter with the contents translucent through skin require cryodestruction by freezing combined with adhesion of a cryoapplicator actively supplied with liquid nitrogen until observing a freezing zone going beyond a projection of a cyst diameter by 2 mm all around that is followed by spontaneous thawing. Between the freezing procedures at the stage of thawing, a cyst is opened by dissection of the frozen tissues, evacuated laterally after compression thawing; the cavity is washed by antiseptics, that is followed by cryoinflation; cryodesctruction is completed by cryocompression freezing with covering and pressing the cyst walls together. If observing the cysts with the opaque contents being more than 4 mm in diameter, a lesion is frozen at large with a freezing zone going beyond a projection on a skin or mucosa surface by applications combined with adhesion of an active applicator, or by pulse-type cryoirrigation on a projection of the cyst centre and before complete thawing, ice-coated tissue is cut in the projection centre by a heated scalpel, or the frozen tissue is dissected by focused carbon laser emission or a radio wave scalpel penetrating inside the cyst. After thawing, the cyst contents is pressed out or removed by a surgical spoon. In the presence of inflammation and suppuration, the cyst cavity is washed by antiseptics. Then a heated rounded cryoapplicator fitting the size of the cyst cavity is inserted therein, and if the cavity is greater than the applicator, a soft ferromagnetic ointment or heat-conducting gel substance is introduced into the cyst cavity to insert the applicator therein, and a ring-shaped permanent magnet is arranged to surround a projection of cyst.
