LETZ



What is LETZ? >
You may not be familiar with this term, as the technique is newer than Laser procedures for treatment of the cervix. LETZ stands for Loop Excision Transformation Zone of the cervix using Electrosurgical technique. This is a procedure designed to diagnose and/or treat the uterine cervix (neck of the womb) of women with abnormal smear tests. A number of other names (acronyms) have been used to describe the procedure, including LLETZ (Large Loop Excision of the Transformation Zone of Cervix, Loop Cone Biopsy and in United State the term is LEEP ( Loop Electrosurgical Excision of the Transformation Zone). All depict a procedure that uses an electrical energy generator, attached to a fine wire loop that when energized, functions as a precise and rapid surgical tool. This instrument is then directed toward an abnormal area on the cervix and may be used quickly, effectively and painlessly to remove the abnormal tissue. The West London Colposcopy service uses the latest in electrosurgical technology is available.

Who will benefit from this procedure? >
Any woman with a significantly abnormal smear may benefit. If in such women, the examining physician is able to see an area of abnormal tissue during the colposcopic examination, the excisional procedure may be performed at the same time or at a later date based on the medical circumstances and wishes of the patient. LETZ is particularly useful in-patients who have abnormal cells entering into the cervical canal. This area is at the greatest risk of containing invasive cancer and thus this area must be removed and examined for accurate diagnosis. Because the procedure is performed in the colposcopy suite, in a nearly painless fashion, the woman avoids the time, discomfort and cost associated with an in-hospital visit for a cone biopsy. Because of the ease of performing the procedure, general anaesthesia (being "put to sleep") is almost always unnecessary.

When should I be concerned enough to phone? >


What restrictions are there following the procedure? >
For 3 - 4 weeks there should be no intercourse and no use of tampons. Normal work or activity may be resumed the same day. Heavy exercise should be avoided for three days, and hot tubs and hot whirlpools should be avoided for 4weeks.

When should I return for a follow-up? >
Specific instructions will be given. In general the follow-up visit will be between 4 weeks to 6 months after the treatment. It is important that you do not have a cervical smear test or pelvic examination elsewhere prior to that visit in the colposcopy unit.


Are there any long-term effects of the loop excision? >
There are no long-term bad out come have been showed after this procedure with respect to fertility and childbirth. However, the effect (damage) on the cervix is identical to, and, in most cases, less than that associated with other procedures such as cryotherapy (freezing therapy), laser therapy, or surgical conization. With the exception of deep cervical conization, So far none of the research has shown that these procedures have been associated with infertility, pregnancy loss, or premature labour. Consequently, unless a loop excision is unusually extensive, it is likely there will be no increased risk of these side effects. creased risk of these side effects.
