LEEP: Loop Electrosurgical Excision Procedure
Loop Electrosurgical Excision Procedure (LEEP) uses alternating electrical current to remove abnormal cervical tissue, which provides a specimen for pathological review. Historically, physicians have used high frequency current for lesion removal as early as the 1940s. The introduction of the large loop with an insulated cross bar in 1989 by Prendeville revolutionized the treatment of cervical dysplasia. Other methods, such as cryotherapy and laser vaporization evaporated tissue, did not allow for pathologic review. LEEP confers the advantage over cryotherapy and laser by providing tissue for histopathological review, thus allowing for prediction of recurrence of disease .
