Examination: conical excision mainly refers to cervical conical excision, which can be used for examination. If the cytologic examination of cervical scraping reveals malignant cells but there is no abnormality in the colposcopic examination, the diagnosis can be further confirmed through cervical excision. In addition, if the biopsy of the cervix is carcinoma in situ, the scope of the lesion and whether there is infiltration can be determined through conical excision. 2. Treatment: Conical excision can also be used for treatment, if the patient with chronic cervicitis is not effective through conservative treatment, cervical conization can be performed. Cervical resection is best carried out 3-7 days after menstruation, so as to reduce bleeding, should be avoided before menstruation surgery, after the operation should follow the doctor’s instructions for oral antibiotics and antiemetic drugs, to prevent infection and bleeding, if the bleeding is more than 10 days, it is also necessary to carry out suture ligation.
