Conservative management of vaginal intraepithelial neoplasia (VAIN) by laser CO2.

Carbon Dioxide Laser ablation therapy was originally offered to 25 women with Vaginal Intraepithelial Neoplasia (VAIN). The disease was primary in 12 and secondary after a previous hysterectomy in 13 cases. Treatment was accomplished under local anesthesia in 22 cases and was well-tolerated by all patients. The age of the patients ranged from 19 to 68 with a mean age of 44 years. All women were followed-up by cytology and colposcopy within a time period of 35 to 82 months (mean 49 months). Eight patients relapsed resulting in a failure rate of 32%. A second Laser CO2 treatment was offered to these patients with a final cure rate of 84% (21/25). The four cases in which the disease reappeared, after the 2nd treatment, were managed by upper colpectomy (3 cases) and follow-up (1 case). Laser CO2 ablation is an acceptable treatment modality for VAIN considering the promising cure rates and the preservation of the anatomic integrity of the vagina. Close colposcopic follow-up of these patients is necessary for early detection of disease relapses.
