近几年已用冷冻疗法(Cryosurgery)、电烙术及二氧化碳激光治疗子宫颈管上皮内赘生物(CIN).冷冻疗法在一些选择病例中的失败率为10%左右,且在严重的结构不良及原位癌中的失败率高于轻度及中度的结构不良.这可能与病变的扩展范围有关.材料和方法:宫颈锥切标本319例,将未固定的锥切标本自前壁正中纵切开,钉在软木板上于福尔马林溶液内固定.至少二小时.然后按时针方向沿宫颈纵轴并与粘膜垂直,每隔2～3mm切成一片,
Cryosurgery, electrocautery, and carbon dioxide laser have been used to treat cervical intraepithelial neoplasms (CINs) in recent years. Cryotherapy has failed in some selected cases at a rate of about 10% and is associated with severe structural dysfunction And in situ carcinoma of the failure rate is higher than mild and moderate dysplasia.This may be related to the extent of the lesion.Materials and methods: 319 cases of cervical conical specimens, the unfixed conical specimens from the front wall Longitudinal incision, nailed to the cork board in formalin solution fixation at least two hours and then clockwise along the cervical longitudinal axis and perpendicular to the mucosa, every 2 ~ 3mm cut into pieces,
