What is LEEP?

Loop electrosurgical excision procedure (LEEP), uses a low-voltage electrical current to remove abnormal tissues of the cervix. It has an advantage, therefore, over the destructive techniques (CO2 laser and cryocautery) in that an intact tissue sample for analysis can be obtained. LEEP also is popular because it is inexpensive, simple, and typically has few risks or side effects. LEEP is also known as large loop excision of the transformation zone (LLETZ).

This procedure is used most often for treating mild to moderate dysplasia (abnormal changes of the cells lining the cervix or precancers) that have been identified by colposcopy and/or cervical biopsy. In certain situations, severe dysplasia and noninvasive cancer that are localized and can be removed, may also be treated by LEEP.
