LLETZ (large loop excision of the transformation zone)

LLETZ is the most common treatment for abnormal cervical cells. LLETZ is also known as loop diathermy, loop cone, loop biopsy, or loop excision.

What happens?

LLETZ can sometimes be carried out at the same time as a colposcopy and involves cutting out the area of the cervix where abnormal cells have developed. This is done using a thin wire loop that is heated with an electric current.  A small ball electrode is used to seal the wound.

The procedure usually takes 5-10 minutes. A local anaesthetic is usually used to numb the area, this is injected into your cervix with a needle. It is not usually painful, although you may feel some pain similar to period pain.

LLETZ is usually performed as a day case treatment meaning you can go home the day of your procedure. You will have some bleeding or discharge for about 4 weeks. To avoid any infection you should not use tampons or have sex until your cervix is totally healed and the bleeding has stopped.

Be sure to discuss any concerns you have with your consultant.
