LLETZ (Large Loop Excision of the Transformation Zone) is a procedure used to treat pre-cancerous changes of the cervix (the mouth of the womb). It allows us to remove abnormal cells early, helping to prevent the development of cervical cancer.

The procedure can be performed under either local or general anaesthetic, depending on what is most appropriate for you.

During the procedure, stirrups are used to allow safe access to the cervix, and a speculum is gently inserted, similar to what is used during a Pap smear. A solution of iodine or acetic acid is applied to clearly identify and outline the affected area.

If the procedure is done under local anaesthetic, this is injected around the cervix to ensure comfort. A fine, semicircular loop electrode is then selected according to the size of the lesion. The abnormal area is removed with a clear margin, usually in one or two smooth passes.

The tissue sample is sent to the laboratory for detailed analysis. This confirms the stage of the abnormality and whether the area has been completely cleared. In some cases, further treatment or an additional biopsy may be required.

Ongoing follow-up is essential after a LLETZ procedure. Regular review allows us to monitor healing and ensure that the cervix remains healthy in the future.
