I. Precautions before hysteroscopy 1. Hysteroscopy is best performed 3 to 7 days after menstruation. Because of the thin endometrium, less mucus and bleeding during this period, the uterine cavity lesions are easy to see. Patients with irregular bleeding can be examined at any time after hemostasis, and antibiotics are given to prevent infection if necessary. 2, should not be examined during pregnancy to avoid adverse consequences. 3.The examination should not be performed when there is acute genital inflammation to prevent the spread of inflammation. 4, in the lesion activity or bleeding is also not suitable to do the official cavity examination. 5. When endometrial cancer has been identified, the examination should not be performed to avoid the spread of cancer. Precautions after hysteroscopy 1. There may be a small amount of bloody vaginal discharge within 2-7 days after the examination. Keep the perineum clean after hysteroscopy. Prohibit sexual intercourse and bathing for two weeks after the operation to prevent infection, because the official opening is not yet closed tightly during this period and bacteria can easily invade. 3.After the examination, give antibiotics to prevent infection if necessary, and treat the original disease. 3. Does hysteroscopy hurt? Are there any side effects? Hysteroscopy is the application of ultra-fine optical fibers to pass a tiny “electronic eye” through the body’s natural orifices of the vagina and cervix and directly into the cavity for examination and treatment. The majority of patients can tolerate either fiberoptic hysteroscopy or rigid hysteroscopy, except for special cases such as young children and postmenopausal uterine atrophy. For patients who are nervous or have medical comorbidities, pain relievers, sedatives or antispasmodic drugs can be given before surgery to reduce intraoperative discomfort. The greatest advantage of hysteroscopy is that it can not only determine the site, size, appearance and scope of the lesion, but also make a detailed observation of the tissue structure on the surface of the lesion and take the material or position the uterus for scraping under direct vision, which greatly improves the accuracy of the diagnosis of intrauterine diseases and updates, develops and makes up for the deficiencies of traditional treatment methods. During the examination, there is no need for anesthesia, so there is no need for fasting and hospitalization. After the examination, you can go home and do your daily activities the next day without resting or taking any supplements.
