Loop electrosurgical excision procedure for CIN

Am Fam Physician. 1992 Aug;46(2):505-20.


The loop electrosurgical excision procedure, also referred to as large loop excision of the transformation zone, is gaining acceptance in the United States as a method for treating cervical intraepithelial neoplasia. Loop excision of cervical tissue is accomplished using a high-frequency alternating current (radiofrequency) and thin wire loop electrodes. Loop excision may be in the form of simple excision of the transformation zone or electrosurgical loop conization. The specimens obtained using this technique are suitable for histologic evaluation. Loop excision, which is usually performed under local anesthesia, is associated with minimal short-term and long-term morbidity. Patient acceptance is high. Family physicians who perform colposcopy should consider using loop electrosurgical excision to treat cervical intraepithelial neoplasia in the outpatient setting.
