[Conization with positive margins]

We received all conizations performed between 1986 and 1997. The incidence of positive margins conization for cervical intraepithelial neoplasia is 7.8% (23.8% in others studies). Persistent or recurrence disease occur only in 35% of cases; so new treatment is not always usefull and cytology and colposcopy are adequate for follow-up.
