What is it?

A cone-shaped piece of tissue (conus) is excised from the cervix. This may be done with a surgical knife or with a laser beam. This treatment may be appropriate for larger lesions and may be performed under general anaesthesia during an outpatient admission or a hospitalisation.

When is it indicated?

After an abnormal pap smear, if abnormalities are observed.


The abnormal portion of the cervix is removed by performing a conisation. This may be done using a loop excision or using a knife, if the lesion is larger. A thin, metal loop that is heated electrically is used to perform a loop excision.

Guidelines for at home

It is possible that you will experience vaginal discharge or bleeding for a few days. During the first few days, this may also be accompanied by a feeling similar to menstruation or even some cramp-like lower abdominal pain. Pain medication can also help with this. Because the cervical mucosal layer needs to heal, you are advised not to have sexual intercourse for three to four weeks and to refrain from using tampons or vaginal douches.

When should you contact your physician?

If you have heavy bleeding, foul-smelling vaginal discharge, a fever higher than 38°C or worsening lower abdominal pain.
