[Laser treatment of premalignant diseases of the uterine cervix. Experiences from a central hospital].

During the six-year period 1984-89, 387 patients with cervical intraepithelial neoplasia were treated with CO2-laser. The procedures were performed under local anesthesia in the outpatient clinic. 342 patients underwent conization, 45 vaporization. Complications occurred in 28 patients treated with conization; the most common being postoperative bleeding, seen in 12 cases. In 75% of the cases there was good correlation between histologic examination of the cone biopsy and cervical biopsy/curettage. In 41 patients (12%) the resection borders were involved or indeterminate. Persistence or recurrence was observed in two patients treated by vaporization and 11 treated by conization. Recurrence was diagnosed after 9-65 months of follow-up.
