Cervical lesions are one of the most common diseases in women, and its most serious condition is cervical cancer. Among women’s cancers, cervical cancer has the second highest incidence after breast cancer. In developed countries, its incidence has declined significantly. It is largely attributed to the early treatment of precancerous cervical lesions. In developing countries, due to imperfect screening, the incidence of cervical disease is six times higher than in developed countries, increasing at a rate of approximately 2%_3% per year, with 80% of patients diagnosed as having invasive cancer. In recent years, the trend of cervical cancer patients is significantly increasing. This can be explained by the increase in human papilloma virus (HPV) infection, and it can even be said that cervical cancer is in a sense an infectious disease. The problem is that the development of cervical precancerous lesions into cervical cancer is a relatively long process. It is about 10 years. Cervical cancer is a preventable and curable disease. The key is screening, prevention and timely detection of early stage cervical cancer with appropriate treatment. Attention to sexual hygiene can reduce the risk of not only cervical cancer, but also other sexually transmitted diseases (STDs). Cervical lesion is an as yet unqualified and rather generalized concept. It refers to a variety of lesions that occur in the cervical region. It refers to inflammation, trauma, tumors (precancerous lesions), malformations, and endometriosis. The examination methods for cervical lesions are: gynecological visualization, palpation, cervical smear and microscopy, colposcopy, biopsy taking and pathological histological examination. Treatment of cervical lesions Depending on the extent of the lesion, the patient’s age, marital status, and the conditions of follow-up, medication, physical therapy (freezing, electrocoagulation, laser, etc.), and surgery (cervical conization, hysterectomy) are available. Cervical conization can be performed with a general scalpel or with a LEEP knife, also known as a high-frequency electric wave knife. It is a new technology first reported by the French in 1981 and developed in recent years. It is currently the most advanced means of treating cervical disease in China and internationally, which uses low voltage, high current and a tiny ring-shaped electric knife (also known as LEEP knife) to remove cervical lesions. The LEEP knife has many advantages over traditional electric knife surgery in the treatment of cervical lesions: 1, it can achieve very fine surgical results that cannot be achieved by traditional electric knife. 2, rarely occurs the phenomenon of tissue pulling and charring caused by the traditional electric knife, and less damage to the surrounding tissue. 3, pain reduction, less chance of scarring, less complications (bleeding and infection). 4.No danger of electric current passing through the body. 5.The electrode plate does not need to be coated with electrode paste, so there is no risk of burns. 6.The operation time is short, 3-5 minutes on average, easy to operate, painless and cost less, only local anesthesia is used. Indications for LEEP knife: cervical erosion, cervical warts, cervical precancerous lesions (CINⅠ, CINⅡ). Since the introduction of LEEP knife technology in the city in May 2005, our hospital has been relieving the pain of many patients with cervical lesions.
