Cervical laser cautery

Laser is a simple, rapid, effective, and less complication for the treatment of cervical erosion. The carbon dioxide laser is often used to illuminate the erosive tissue by emitting a beam of light onto the smashed surface, and the squamous epithelium can be grown after the ecdysis is detached. Laser treatment has anti-inflammatory, analgesic and tissue-promoting effects. In the course of treatment, since the laser knife does not touch the cervical tissue, the depth of cauterization is easy to grasp. Some patients in the treatment may have a vaginal burning sensation. There will be drainage or bloody secretions in the vagina 1 to 2 weeks after treatment. The general healing time is about 1 month. Laser treatment should be carried out after menstruation is clean. After treatment, patients should pay attention to keep the vulva clean, prohibit the house, ban swimming and bath for 2 months, and review it regularly as required. If the vaginal bleeding exceeds the menstrual volume after treatment, go to the hospital for examination. Treatment of diseases: cervical intraepithelial neoplasia chronic cervicitis Indication 1. Chronic cervicitis. 2. Cervical endometriosis. 3. Mild and moderate cervical intraepithelial neoplasia (cin i, ii grade). Contraindications 1. Acute vulva, vagina, cervix or (and) pelvic inflammatory disease. 2. Severe cervicitis, did not rule out malignant changes. 3. Pregnant women, patients with frequent menstruation, and patients suffering from systemic diseases (such as severe heart disease, blood disease, liver disease, etc.) are refrained from using laser treatment. Preoperative preparation 1. routine cervical smear examination to find cancer cells, suspicious clinical and cytological examination, cervical biopsy should be performed. 2. People with acute genital inflammation should be treated with anti-inflammatory treatment. 3. Forbidden sex for 3 days before surgery. Surgical procedure 1. Position: The position of the stone. 2. Disinfection: routine disinfection of the vulva, vagina and cervix. 3. Cauterization of the cervix: with co2 laser, wavelength 10.6m, output power 20 ~ 30w continuously adjustable, the knife head distance 2 ~ 5cm, spot diameter 0.3 ~ 0.5cm, aligned with the lesion tissue for scanning vaporization, from bottom to top, Repeated scanning from the outside to the inside, the boundary is about 2mm beyond the lesion, and the cauterization depth is about 2~3mm. 4. Cauterization of the cervical gland to store cysts: first use a laser to make a small hole in the center of the cyst, use a forceps to squeeze the viscous cyst fluid, and then vaporize the entire capsule wall. 5. Surgical wound treatment: disinfect the cervix again. complication 1. Bleeding: more common. The predilection site is about 6 o'clock in the posterior lip of the cervix. A small amount of bleeding can be used to stop the bleeding with a large cotton swab or to disperse the laser beam to > 2mm, burn the hemorrhage and surrounding, and make the blood vessels coagulate; if there is more bleeding, it can be blocked with vaginal tampon or gauze, and taken out after 24 hours. 2. Postoperative pelvic infection: manifested as lower abdominal pain, cervical greenish black, secretions with odor, anal examination of uterine tenderness, local or systemic anti-inflammatory treatment. 3. Postoperative cervix stenosis: Use a vascular clamp to separate the membrane of the adhesion, and if necessary, cervical dilatation.
