The current methods of cervical conization are mainly cervical cold knife conization and LEEP, and the exact method that should be used depends on the condition and purpose. Cold knife conization of the cervix is the use of a common scalpel for conization, which is used during confirmatory surgery and CIN3 treatment, where the edges of the specimen removed do not affect the pathological diagnosis. However, the procedure needs to be performed under anesthesia and the wound needs to be sutured to stop bleeding. LEEP (loop electrosurgical excision procedure), which is called coil excision in Chinese, uses an electrically charged coil to “pluck out” a cone-like piece of cervical tissue by passing it across the cervix, and the wound is hemostatic with electrocoagulation. The advantages are that it is easy to perform, the procedure is short, no anesthesia is needed, and it is less painful. Due to charring at the edges of the excised tissue, it has some influence on pathological diagnosis. It is mostly used for the treatment of precancerous lesions below the level of CIN2, and also when determining the extent of early cervical cancer infiltration.
