CONE BIOPSY (LLETZ)
LLETZ
LLETZ stands for Large Loop Excision of the Transformation Zone. This procedure entails removal of the cervix beneath the lower uterine segment. LLETZ is utilized in the treatment and removal of precancerous and Human Papilloma infected cells of the cervix. If left untreated, these cells might progress to cancer of the cervix over time. Therefore, close follow up is essential with repeat pap smears and colposcopy as needed.
The LLETZ procedure is generally performed under local anesthetic in an office setting or possibly in the operating room. A fine wire loop is energized with electricity to thinly shave away the abnormal tissue on the cervix with very little damage to the surrounding tissue. In addition, the blood vessels are sealed with a cautery device to minimize any bleeding. This procedure is often preferred over a cold knife cone biopsy which is more commonly performed under general anesthetic to cut out the abnormal area and over-sewn with sutures to prevent continued bleeding.
Risks of the LLETZ procedure include excessive bleeding from the cervix possibly requiring additional surgery or packing. Localized infection is another possibility. Last, although uncommon, the cervix may be weakened by the procedure and may increase the rate of pregnancy loss or miscarriage.
