Cryotherapy is often the best way to treat a number of pathologies. Tissue subjected to temperatures below -22°C is destroyed. The freezing of the cells causes them to burst. The destroyed tissue stays in place until healing is completed and it then sloughs off. Because of this, the risk of infection is almost zero.
Procedures such as electrosurgery, laser, cautery, and removal by scalpel are all more prone to infection and scars are usually left. Cryosurgery does not normally cause the formation of scar tissue although pigmentation will be lost, sometimes permanently. For further information and for a demonstration contact Genesis Medical
The most common applications are for the removal of warts and verruccae, cryosurgery of the cervix to treat CIN, various ENT procedures, treating Condylomata, and dermatology.
Gynaecology, General purpose and Dermatological uses
Treating CIN and other lesions with cryosurgery
CIN or cervical intraepithelial neoplasia is a very common pre-cancerous condition of the cervix which is usually detected after an abnormal PAP smear and confirmation by colposcopy. Treatment is routine and involves destruction of the dysplasia usually by cryotherapy, laser vaporisation or a cone biopsy should tissue be required for pathology. After cryosurgery or laser, tissue is not available for examination.
Cryosurgery is an excellent therapy. It is simple to perform and it is very effective for treating CIN grades I.II.and III. The procedure involves little or no pain, and because the destroyed tissue remains in place until the regrowth of healthy tissue is complete, there is virtually no risk of infection.
For other lesions such as condylomata, VAIN (vaginal intraepithelial neoplasia), VIN (vulvar intraepithelial neoplasia), PAIN (perianal intraepithelial neoplasia), Cryotherapy is an excellent solution. As a rule, lesions smaller than 1cm diameter are most effectively handled by cryotherapy.
The Wallach LL100 and LLCO2 provide controlled freezing so that the area and depth of freeze are easily contained as appropriate.
Other methods for treating CIN are by Loop biopsy or LEEP. Lasers are today rarely used for these procedures
General purpose cryosurgery
Genesis Medical supplies the Wallach LL100 cryofreezer ( for use with N2O gas) and the LLCO2 (for use with CO2 gas) which feature both an instant effective freeze and instant defrost. Immediately after ending the freeze cycle activating the defrost detaches the tissue from the tissue.
The Wallach LL100 and LLCO2 provide controlled freezing so that the area and depth of freeze are easily contained as appropriate. Liquid Nitrogen sprays are useful for larger shallow lesions (such as keratoses) but because the liquid nitrogen immediately forms a frost barrier on the surface if the tissue sprays are not effective in treating CIN or warts where a good depth of freeze is needed to destroy the roots..
The most common general purpose applications are for the removal of warts and verruccae, various ENT procedures, and treating Condylomata.
Treating keratosis and large areas where a shallow freeze is required a liquid nitrogen spray is ideal. As soon as the liquid nitrogen touches the tissue a frost forms and forms an insulating barrier preventing a depth of freeze from forming. Genesis Medical supplies the excellent Wallach UltraFreeze
