Colposcopically directed conization for frozen-section examination in the management of cervical intraepithelial...

We found colposcopically directed conization for frozen-section (F/S) examination to be 100% accurate in ruling out the presence of invasive cervical carcinoma. Therefore, the definitive treatment for cervical intraepithelial neoplasia (CIN)--hysterectomy in women who do not want more children--could be performed while the patient was still under the anesthetic used during procurement of the conization specimen. This technique reduces the risk of using anesthesia a second time and also reduces the costs of CIN treatment. Colposcopically directed conization should be done by experienced colposcopists only.
