We use two kinds of
laser treatment, namely,
laser vaporisation and
laser excision conisation.
Laser vaporisation is a widely used method of localised ablative treatment based on both histologically confirmed
cervical intraepithelial neoplasia and clear colposcopic visualisation of the upper limit of the lesion.
Laser excision conisation is performed, if
cervical intraepithelial neoplasia reaches the endocervix, being out of colposcopic view, and the squamocolumnar junction is localised in the endocervical canal. 116 patients with
cervical intraepithelial neoplasia were treated with the
CO2 laser. 81 (70%) were subjected to
laser vaporisation, 35 (30%) to
laser excision conisation. Intraoperative
bleeding was rarely seen. After
laser vaporisation, no complications were observed, but
laser excision conisation complications occurred in one patient who developed postoperative cervical
stenosis, and in another patient, who had postoperative
bleeding requiring surgical examination. Follow-up with colposcopy and cytologic smears was carried out every 6 months. Recurrence of disease 6 months or later after
laser treatment was seen in 6 patients (7.4%) after
laser vaporisation and in 2 patients (5.7%) after
laser excision conisation. This report shows the advantages of the
carbon dioxide laser in comparison to cold knife conisation in the treatment of
cervical intraepithelial neoplasia.
