The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) and early stage cervical cancer discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ). It is considered a type of conization. [1]
[8] [18] The first use of an electrosurgical generator in an operating room occurred on October 1, 1926 at Peter Bent Brigham Hospital in Boston, Massachusetts. The operation—removal of a mass from a patient’s head—was performed by Harvey Cushing. [19] The low powered hyfrecator for office use was introduced in 1940.
Unlike other types of electrosurgery, the hyfrecator does not employ a dispersive electrode pad that is attached to the patient in an area not being treated, and that leads back to the apparatus (sometimes loosely but not quite correctly called a "ground pad"). It is designed to work with non-grounded (insulated) patients.
