[Laser use in the uterine cervix. CO2 or KTP laser].

86 patients with cervical neoplasia were treated by conization. The KTP/532-laser was used in 52 cases (group 1) and the conization was performed with a carbon dioxide laser in 34 other cases (group 2). The operation took approximately 30.5 min in the KTP group and 13.5 min in the carbon dioxide group. Complications occurred in 2 cases of the KTP-laser treated patients. In group 2 no complication were observed. The time of hospitalisation was 5 days. The thermal damage of the cut-edge came up to 1 mm (group 1) and 0.1 mm (group 2), respectively. In 4 cases the histological examination was negatively effected by the heat of the KTP laser. In group 2 no affects were observed. The advantage of the KTP-laser is its styptic effect whereas the CO2-laser is better for an histological examination.
