Cervical conization, also known as a cone biopsy, is a removal of a cone-shaped piece of tissue from the cervix by one of the following methods: cold-knife excision, laser-assisted excision, or loop electrosurgical excision procedure. The latter approach is also known as diathermy conization.
The indications for cervical conization are the following:
- A tear in the cervix after previous deliveries;
- Elongation of the cervix;
- Precancerous cervical lesions (dysplasia).
If a patient plans to become pregnant, a time interval between cervical conization and subsequent pregnancy should be more than 6 months.
How Is the Surgery Performed?
The surgery is performed under general anesthesia. It takes 5–10 minutes to compete.
During cervical conization, the incisions are made inside the vagina and are closed with absorbable sutures.
Perineoplasty can be performed in conjunction with this procedure.
The excised piece of the cervix is subjected to histological examination.
What Should Be Known After Surgery?
- Swimming is discouraged for 6–8 weeks;
- The patient should avoid conditions that can suddenly increase intra-abdominal pressure (for example, constipation, sneezing, and coughing);
- The patient should refrain from sexual intercourse for 6 weeks after the surgery;
- Physical activity is discouraged approximately for 2 months, until the surgical wounds heal completely.
