Conisation of the cervix
What is conisation?
During conisation, the gynaecologist removes a small piece of tissue from the cervix. This piece is shaped like a cone, which is where the name comes from. The procedure is usually performed via the vagina, so no incision in the abdomen is needed. The removed tissue is sent to the laboratory for further examination. This allows us to determine exactly which cells are present and whether further treatment is required.
Why is a conisation performed?
A conisation is performed when abnormal cells are found in the cervix, for example after:
- an abnormal smear test
- a colposcopy
- a biopsy that shows suspicious cells
The aim is to remove abnormal cells and examine the tissue so we can make an accurate diagnosis. This helps detect or prevent cervical cancer at an early stage.
How do you prepare for conisation?
Your gynaecologist will give you clear information beforehand. The procedure is usually done as a day admission, so you can go home the same day. A conisation may be performed under local anaesthetic or a short general anaesthetic. Your gynaecologist will also discuss whether you need to temporarily stop taking certain medication.
How does the procedure proceed?
The gynaecologist uses an instrument inserted through the vagina to reach the cervix. A thin loop or small surgical knife is used to remove a cone-shaped piece of tissue. The procedure usually takes 15 to 30 minutes. Afterwards, the gynaecologist may treat the area to prevent bleeding. You will then go to the recovery room or return to your room.
Results and follow-up
The removed tissue is analysed in the laboratory. The results are usually available within one to two weeks. Your gynaecologist will discuss the results with you and determine whether any further follow-up is needed. In many cases, a follow-up smear test is planned afterwards.
