    Abstract:
    AIM AND OBJECTIVE: To evaluate the feasibility of CO2 laser excisional conization in patients with cervical intraepithelial neoplasia (CIN) in an outpatient setting under local anesthesia. DESIGN: A prospective study of women with cervical intraepithelial neoplasia over one year recording early and late complications, cure rate, and patients' compliance. The procedure was performed with a Coherent CO2 laser connected to the colposcope with a micromanipulator. The equipment attaining 19,700 W/cm2, spot diameter 0.43 mm, focus distance 300 mm, and continuous beam. RESULTS: The material included 81 women. Seventy-eight women were treated as outpatients, while three women were admitted for 24 hours observation due to surgical and technical complications during the treatment. Sixty-six percent of the women had bleeding less than 10 ml during the treatment. One woman was admitted 24 hours after surgery due to bleeding requiring suturing. Median operation-time was 11 minutes (range 3-60). All specimens contained CIN. In 76% of the cases the pre- and postoperative diagnosis were identical. Twelve specimens had CIN in one or both margins. Abnormal cytology after conization was found in three cases (4.2%). High patient compliance was found as 92% of the treated women would choose the same kind of treatment if it had to be repeated. CONCLUSION: High success rate, few complications and high patient compliance make the procedure adequate as a routine procedure in treatment and diagnosis of CIN.
