LLETZ Procedure (Large Loop Excision of the Transformation Zone of the cervix)


This procedure is done when your pap smear, colposcopy or biopsy has shown abnormal cells on the surface of your cervix.  Treatment is usually recommended when there is a risk that the abnormal cells may progress to cancer of the cervix. The risk of developing cancer is small and only occurs if the abnormal areas are left without treatment for long periods of time.


The LLETZ treatment aims to totally remove the abnormal cells from the cervix.

A wire loop with an electric current (diathermy) is used to shave off these cells. 

This leaves a raw area on the cervix which heals very well.

The healed cervix should then contain only healthy tissue, without any abnormal cells.

The LLETZ procedure involves a short stay in hospital, usually only a few hours. 

It may be done while you are awake or asleep, although most women find it more comfortable to be asleep. A short acting anaesthetic is most commonly used.

What to expect after the procedure:

  • You may experience some slight "period like" discomfort for a day or so. 
  • Initially bleeding varies from slight to as much as a period.
  • You will probably have a vaginal discharge, brown or blood stained and later clear, usually for about three to four weeks.
  • For the first three to four weeks you should also avoid intercourse, bathing, swimming and heavy exercise in order to promote healing of the cervix and minimize the risk of infection.
  • After the procedure pads rather than tampons should be used.

Possible Complications:

Some women do develop infections after the procedure.

Follow Up:

A post operative appointment will be made for 2 – 4 weeks to discuss results.

An appointment for a repeat colposcopy 6 months following the LLETZ procedure will also be made.

This is to check that the cervix has healed well, without residual or recurrent abnormal cells.

Although the procedure will remove all visible abnormal areas, there is still a possibility that the abnormal cells may recur (approximately a 5-10% chance).

Follow up is extremely important.
