    Laser conization offers a less invasive treatment for cervical intraepithelial neoplasia, showing reduced blood loss and shorter hospital stays compared to conventional methods.

    Area of Science:

    • Gynecology
    • Surgical Oncology
    • Laser Medicine

    Background:

    • Cervical intraepithelial neoplasia (CIN) and chronic cervicitis require effective treatment.
    • Conventional conization has established protocols but can involve significant blood loss and recovery time.

    Purpose of the Study:

    • To compare the efficacy and outcomes of laser conization versus conventional conization for cervical preneoplastic disease.
    • To evaluate differences in blood loss, hospitalization, and postoperative complications between the two methods.

    Main Methods:

    • A comparative study involving 49 patients with cervical intraepithelial neoplasia or resistant chronic cervicitis.
    • Patients were divided into two groups: 25 undergoing CO2 laser conization and 24 undergoing conventional scalpel conization.

  • Hemostasis in the conventional group was achieved with sutures; the laser group used a combination method.

    • Main Results:

    • Laser conization resulted in minimal blood loss compared to 119 ml in the conventional group.
    • Hospitalization was shorter for laser conization (5.2 days) versus conventional (7.0 days).
    • Postoperative bleeding and discharge were significantly reduced in the laser group.

    Conclusions:

    • Laser conization demonstrates greater visibility of the squamocolumnar junction and a lower incidence of cervical strictures.
    • The CO2 laser is an effective surgical modality for treating cervical preneoplastic disease when applied cautiously.
    • Initial results suggest laser conization is a favorable alternative to conventional methods.
