LLETZ stands for 'large loop excision of the transformation zone'. In the USA, this procedure is called LEEP or 'loop electrosurgical excision'.

What happens during LLETZ?

LLETZ is usually takes about 10 minutes and is performed under local anaesthetic. If you need to have a large area of tissue removed, or if you are very anxious about the treatment, you may be given general anaesthetic. You may have this treatment at the same time as a colposcopy.

The transformation zone is an area inside the endocervical canal. The exact position of this area varies depending on your age and whether you've had children. For this reason the transformation zone can't always be seen clearly during a cervical smear. Your consultant can examine the area more closely during a colposcopy. During LLETZ your consultant will cut away the transformation zone using a loop of wire and an electric current. The area will also be sealed at the same time.

Going home after LLETZ

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.
