Hysteroscopic surgery is not a traditional open surgery and therefore does not require an incision. Open surgery is a transabdominal surgery, in which the abdominal wall is cut open to enter the abdominal cavity for treatment, which is relatively invasive and does not conform to the minimally invasive principles of modern medicine. Hysteroscopic surgery is a modern minimally invasive surgery, in which the hysteroscope body is inserted into the uterine cavity through the vagina and cervix, and the treatment is achieved by means of electric cutting. Hysteroscopic surgery is less invasive and can preserve the physiological integrity of the uterus, and it is not easy to leave scars after the surgery and does not affect the aesthetics. In addition, the risk of bleeding during hysteroscopic surgery is relatively small, and patients will not feel very painful. Moreover, the operation time is short, recovery is fast, and ovarian function is not affected. The time to have hysteroscopic surgery is usually 3-7 days after menstrual cleansing. Sexual intercourse is prohibited for 2 weeks after the operation and antibiotics can be given for treatment if there are symptoms of infection. If the patient is in good health and the endometrium recovers well, pregnancy preparation is usually done 3 months after surgery.
