Abstract

The trend in the treatment of premalignant lesion is toward more conservative approach in which affected area is effectively destroyed. The purpose of treating precancerous lesions is to destroy the affected areas and thereby reducing the mortality and morbidity associated with cancer cervix. The cryotherapy technique uses a cryoprobe with a tip made of highly conductive metal (usually silver and copper) that makes direct surface contact with the ectocervical lesion. A substantial drop in temperature is achieved when a compressed refrigerant gas is allowed to pass through a tiny aperture in the cryoprobe which causes the gas to expand to freezing temperature leading to formation of ice. Large loop excision of the transformation zone (LLETZ) uses monopolar current and therefore needs a ground plate for the electricity to return to the electrosurgical unit after achieving its effect at the point of contact between the loop and the tissue.
