[Radiosurgical excision in the treatment of cervical intraepithelial neoplasia]

39 patients affected by CIN had undergone radio surgical excision. This non-traumatic method employs 3.8 MHz radio waves are employed to cut and/or coagulate. The radio surgical excision was carried out by a loop electrode, or microneedle, according to the colposcopic, histologic and microcolpohysteroscopic characteristics of the cervical lesion. In fact 14 patients, among whom 11 affected by CIN I and 4 by CIN II with a total visibility of squamous columnar junction and not extended lesion of the cervical canal, had undergone radio surgical excision through various dimensions loop according to the size of the tissue to be excised. Whereas 10 CIN II patients who had not entirely visible squamous columnar junction or large cervical canal lesion, and 14 CIN III patients underwent to radiosurgical conization through a subtle and extensible tungsten thread according to the size of the tissue to be excised. In the 100% of the both groups the recovery was confirmed after three and six months. Inno cases cervical canal stenosis was observed and the squamous columnar junction resulted well visible. In both groups no thermal damages on the excised tissue, which could create difficulties on the histological diagnosis, were observed. Therefore, this method resulted an easy and cheap technique to be executed in surgery with excellent results under the therapeutic and economical aspect.
