LLETZ stands for "large loop excision of the transformation zone". LLETZ procedures are performed to remove abnormal, pre-cancerous cells from the cervix, and these cells are found in the "Transformation Zone". A LLETZ is usually done after a Cervical Screening Test, colposcopy and cervical biopsy have confirmed the presence of abnormal cells.
Doing a LLETZ is like taking an ice cream scoop out of the crevix, but using a very thin, hot wire (the "Loop"). It aims to remove the entire TZ so that no abnormal cells are left behind. The whole procedure is quite (10-20 minutes) and can be done under local or general anaesthetic.
After a LLETZ women may have mild pain and light bleeding that will settle in a few days. Most women feel completely normal a few days after surgery. Full recovery of the cervix takes 4-6 weeks and it is strongly advised to avoid sex, tampons, swimming, spas and strenuous exercise for the duration.
