ABSTRACT
Objective:To evaluate the value of diagnosis and therapy of cold knife conization with electro-cautery hemostasis by hysteroscope in the treatment of ceNical intraepithelial neoplasia (CIN).Methods :A retrospective analysis of the clinical data was carried out in 193 cases with CIN underwent cold knife coniza-tion with electrocautery hemostasis by hysteroscope from January 2005 to November 2008, and all patients had pathological diagnosis under colposcopic biopsy.Results:The operative time was from 15 to 40 mi-nutes, and the blood loss dunng operation was from 5 to 25 milliliters.The coincidence rate of histopathology before and after conization was 67.88% in 131 cases.9 CIN Ⅲ patients had positive margins after opera-tion, owing to scab break off bleeding of cervical wound was encountered in 18 cases.No infection and cervi-cal adhesion or stenosis occurred.Conclusions :Cold knife conization with electrocautery hemostasis by hyst-eroscope is an effective diagnosis and treatment for CIN.
