Clinical investigation with KTP/YAG laser for lower genital tract disease.
The KTP/YAG laser (Laserscope) was clinically investigated in treatment of 54 patients, 28 of whom had cervical intraepithelial neoplasia (CIN), 11 who had cervical polyp, 4 with cervical myoma, 9 with condyloma acuminata, and 2 with vulvar tumors.  All patients were treated on an outpatient basis with local anesthesia.  The procedure was performed in contact and noncontact irradiation modes with the tissue by using a bare fiber held in a handpiece with a power setting of 10-15 watts. Laser excisional conization was carried out for the treatment of CIN, laser excision was used for the treatment of condyloma of the cervix, cervical polyp, cervical myoma, and benign tumor of the vulva, and laser vaporization was used for condyloma of the vulva.  The first cure rates were all satisfactory for the follow-up periods of 4-10 months. Complications during and post operation were minimal.  The KTP laser provided good vaporizing ability compared with CO 2 and YAG lasers.  When massive bleeding occurred which could not be stopped with the KTP laser, the YAG laser was used.
