LEEP, abbreviated as lopelectrosurgicalexcisionprocedure, was first reported in 1984 by Cartier, an Englishman. LEEP can be used not only as a diagnostic method for cervical lesions, but also, and more importantly, as a therapeutic tool. Diagnosis of cervical lesions The traditional model is: regular follow-up of patients with abnormal cervical cytology, or multi-point biopsy of the cervix for pathological examination under colposcopic guidance, which inevitably involves incomplete sampling due to the multicentric origin of cervical lesions, and sometimes even repeated sampling for a definitive diagnosis. LEEP, on the other hand, can remove the lesion completely, which reduces the rate of cervical cancer leakage and causes little damage to the lesioned tissue and does not affect the pathological examination results. Treatment of cervical lesions In recent years, with the update of medical equipment and improvement of technology, the detection rate of precancerous lesions of the uterine cervix has increased significantly, especially in young patients. In the past, once diagnosed as precancerous lesions, surgical treatment was often required —- for total hysterectomy, while LEEP achieves minimally invasive treatment for such patients, i.e. the uterus and cervix can be preserved, thus protecting the integrity of reproductive organs and improving the quality of life of patients. LEEP has now become one of the most commonly used methods for the treatment of cervical lesions in Europe, America and many countries and regions of the world.
