LLETZ (Large Loop Excision of the Tranformation Zone)
A thin wire loop that carries an electric current is used to remove the abnormal areas from the cervix. For this procedure, a local anesthetic is given. Electric energy also is used to close off the blood vessels on the surface of the cervix. This reduces the risk of bleeding after the procedure. The abnormal areas are removed for histological study. This allows diagnosis and treatment at the same time. It takes about 10-20 minutes and causes minor discomfort.
Cone Biopsy with surgical blade
This procedure is performed If a larger sample is needed. Through surgery with a surgical blade, a cone-shaped wedge of the cervix is removed. The sample is then examined under a microscope. The conization procedure also may serve as a method of treatment for some cervical disorders because the affected area is removed in many cases. Conization requires general or regional anesthesia in most cases. You may need to be admitted to the hospital for the procedure.
