CryosurgeryCryosurgery is the application of extreme cold to destroy abnormal or diseased tissue. Cryosurgery comes from the Greek cryo meaning icy cold and the word surgery meaning literally hand work or HandiworkCryosurgery is used to treat a number of diseases and disorders, especially skin conditions. Warts, moles, skin tags, solar keratoses, and small skin cancers are candidates for cryosurgical treatment. Some internal disorders are also treated with cryosurgery, including liver cancer, prostate cancer, cervical disorders and, more commonly in the past, hemorrhoids. Although found to be effective, this method of treatment is only appropriate for use against localized diseases with no metastasis.Cryosurgery works by taking advantage of the destructive force of freezing temperatures on cells. At low temperatures, ice crystals form inside the cells, which can tear them apart. More damage occurs when blood vessels supplying the diseased tissue freeze.In the past, the most common method to freeze was using liquid nitrogen as the cooling solution. The super-cooled liquid may be sprayed on the diseased tissue, circulated through a tube called a cryoprobe, or simply dabbed on with a cotton or foam swab. Less frequently, doctors use carbon dioxide "snow" formed into a cylinder or mixed with acetone to form a slush that is applied directly to the treated tissue. Recent advances in technology have allowed for the use of Argon gas to drive ice formation using a principle known as the Joule-Thomson effect. This gives physicians excellent control of the ice, and minimizing complications using ultra-thin 17 gauge cryoneedles.Cryosurgery is a minimally invasive procedure, and is often preferred to more traditional kinds of surgery because of its minimal pain, scarring, and cost; however, as with any medical treatment, there are risks involved, primarily that of damage to nearby healthy tissue. Damage to nerve tissue is of particular concern.Patients undergoing cryosurgery usually experience minor-to-moderate localized pain and redness, which can be alleviated by oral administration of an analgesic or ibuprofen) and application of topical steroid cream. Blisters may form, but these usually scab over and peel away.Category:Medical treatmentsit:Crioterapia Cryotherapy Cryotherapy is used to define several techniques and procedures in the medical community. The most general definition is the local or general use of low temperatures in medical therapy or the removal of heat from a body part to decrease cellular metabolism, increase cellular survival, decrease inflammation, decrease pain and spasm, promote vasoconstriction, and when using extreme temperatures, to destroy cells by crystalizing the cytosol. It can also be called crymotherapy. The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery.Other therapies that use the term are cryogenic chamber therapy and ice pack therapy.Cryotherapy is the application of extreme cold to destroy abnormal or diseased tissue. Cryotherapy is used to treat a number of diseases and disorders, especially skin conditions like warts, moles, skin tags and solar keratoses.Liquid nitrogen is usually used to freeze the tissues at the cellular level. The procedure is used often because of its efficacy and low rates of side effects.For more information, see CryosurgeryCryotherapy is a treatment where a person is placed in a cryogenic chamber for a short duration.The chamber is typically cooled with liquid nitrogen to a temperature of –110 C. For more information see Cryotherapy Cryotherapy is commonly used to treat pain conditions. Most forms of cryotherapy used as passive physical modalities of the management and rehabilitation of both acute and persistent pain conditions, provide transfer of thermal energy by conduction, with the exception of vapocoolant sprays and whirlpool baths . The physiologic effects of cold application include immediate vasoconstriction with reflexive vasodilation, decreased local metabolism and enzymatic activity, and decreased oxygen demand. Cold decreases muscle spindle fiber activity and slows nerve conduction velocity, therefore it is often used to decrease spasticity and muscle guarding. (From the Wikpedia article Cryosurgery.)
