Electrosurgical loop conization of the cervix is a new procedure that is being rapidly accepted for treatment of cervical intraepithelial neoplasia (CIN). Concerns include fragmentation of the specimen that is frequently mandated by the size of the transformation zone and difficulty in using the largest electrosurgical loops. Two cases are presented that demonstrate the inability to accurately assign depth of invasion in cervical cancer when the focus of invasion is transfected. As a result, the patient and physician were forced to decide on whether a radical hysterectomy and pelvic lymphadenectomy were needed based on incomplete information. It is recommended that electrosurgical loop conization be confined to patients where invasive carcinoma is not expected. The use of this new technique for patients with suspected invasive carcinoma needs further evaluation.
