LLETZ biopsy

Large Loop Excision of the Transformation Zone is the technique used to manage pre-cancerous lesions of the mouth of the womb (cervix) . The procedure can be conducted under local or general anaesthetic.

Stirrups are used and access to the cervix is obtained by means of a speculum. Iodene or acetic acid is used to demarcate the affected area.

Local anaesthetic is injected around the cervix. A semicircular electrode is chosen according to the size of the lesion and it is removed with a clear boundary in one or two sweeps. The biopsy is sent to the laboratory for confirmation of stage and clearance. It may be necessary for an additional biopsy or further surgery. In all cases regular review in the future is required.
