Carbon dioxide laser surgery in colposcopy for cervicovaginal intraepithelial neoplasia treatment. 10 years experience and failure analysis.

CO2 laser vaporisation is an effective method in the treatment of cervico-vaginal pre-invasive lesions. In a case-series of 334 patients no case of invasive neoplasia development were registered at longterm follow-up. The failure rate is comparable to those described with traditional surgical methods and are due to the particular topography of the disease.
