Postoperative repair process: vaginal discharge is slightly more yellowish watery or light red watery in 1~2 weeks after surgery, scab starts to fall off in the second week after surgery, some patients have bloody vaginal discharge when the scab is removed, fresh epithelium grows in 3~4 weeks, and the wound surface is completely epithelialized in 6~8 weeks. Postoperative medical advice: 1. Remove the gauze stuffed in the vagina 24h after surgery to stop bleeding and inflammation; 2. Take oral or intravenous antibiotics for 3 to 5 days after surgery to prevent infection; 3. If you have fever or vaginal discharge with odor, consult the doctor in time; 5. Post-operative complications and prevention of LEEP: 1. Post-operative bleeding. Secondary bleeding after surgery often occurs 5 to 12 d after surgery, the amount of bleeding is more than the amount of menstruation, mostly due to deep excision of lesions and combined infection, incomplete hemostasis or excessive hemostasis crust off may be related. Depending on the amount of bleeding, gauze compression, freezing, electrocautery, re-electrocoagulation with LEEP knife, re-suturing, and occasionally hysterectomy may be required. In addition, it should be noted that postoperative strenuous exercise, bathing or showering with too hot water and taking herbal medicines such as ginseng and astragalus can lead to possible postoperative hemorrhage. 2.Uterine perforation or cervical perforation, although extremely rare, may require hysterectomy; 3.Pelvic infection after surgery, the occurrence of secondary infection is related to the postoperative local resistance, wound oozing and prolonged factors, in addition to strict vaginal and cervical disinfection during surgery, oral antibiotics and hemostatic drugs should be routinely taken for 3-5 d after surgery, and vaginal douching, tub bathing and sexual intercourse are strictly prohibited for 2 months after surgery. The postoperative period should be strictly prohibited from vaginal douching, bathing and sex for 2 months. 4. Cervical stenosis or adhesions. The incidence was about 1:5% and was independently correlated with the size of the cervical tissue removed by conization (conization depth more than 2 cm). In addition, postoperative infection, prolonged postoperative bleeding, and secondary conization also predispose to postoperative cervical stenosis. Postoperative attention should be paid to the patient’s first menstrual period for dyspareunia or dysmenorrhea. Cervical dilatation is a simple and effective method to deal with postoperative cervical stricture or adhesions. 5. The formation of cervical canal granulation or polypoid hyperplasia is associated with heavy cervical lesion laceration and inexperience in surgery. At the time of follow-up, the effect of localized silver nitrate cautery or small conization is satisfactory.
