The loop electrosurgical excision proceure (LEEP) is currently one of the most commonly used approaches to treating high grade cervical dysplasia discovered on colposcopic examination. It is also known as "large loop excision of the transformation zone" (LLETZ). The procedure has many advantages including low cost, high success rate, and ease of use. The procedure can be done in an office setting and usually only requires a local anesthetic, though sometimes a general anesthetic is used.
