LLETZ or LEEP

The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ).

LEEP has many advantages including low cost, high success rate. The procedure can be done in an office setting and usually only requires a local anesthetic, though sometimes IV sedation or a general anesthetic is used.
