It is mainly used for the treatment of certain skin cancers. In my facility: www.gentlevetanimalhospital.com I use this less invasive surgical procedure for certain patients that would benefit from it.
The advantages of the procedure resides mainly in the fact that it doesn't require general anesthesia.
This is especially important with high anesthetic risk patients.
The procedure is done as an outpatient procedure, and usually the patient is out of the office within half an hour.
For larger lesions local anesthetic is used, for very small lesions, usually there is no need for it.
Like anything else in medicine, the procedure can have its down sides. Mainly, it might take a few weeks for a lesion to regress and heal, and some lesions may require a follow up treatment.
Another possible down side, is the fact that as the lesion responds to treatment, the area may look inflamed, or reactive, or sometimes in very large lesions it may look necrotic.
Every effort is made to avoid as much as possible damage to normal surrounding tissues, but occasionally this may happen.
Usually a biopsy of the lesion will be done before the freezing.
In conclusion: Cryosurgery is a very valuable tool, and gives an additional treatment modality for our pets.
