With the aging of the population, the number of women who are menopausal is increasing. In order to enjoy a peaceful old age, you have to be responsible for your health. It is important to have regular medical check-ups, to detect possible signs of disease, and to actively seek medical attention for timely detection and treatment. First of all, the definition of menopause should be clearly defined: menopause for more than 12 months, accompanied by changes in blood biochemical indicators, such as FSH>40 IU/L and E2<50 pg/ml. Possible abnormalities after menopause: 1. Postmenopausal bleeding: abnormal uterine bleeding or vaginal spotting for more than 1 year after menopause. 2. Postmenopausal endometrial thickening: This is a gynecologic ultrasound indication of endometrial thickness >5 mm (usually measured at the thickest point of the endometrium, between the endometrial and myometrial interfaces, across the sagittal plane of the uterus). In women with postmenopausal bleeding, the endometrium should first be obtained for pathological examination by means of diagnostic scraping. However, in some patients, the endometrium may not always be scraped out or problems found after menopause by means of diagnostic scraping, for example. For example, endometrial polyps or submucosal fibroids, or even endometrial cancer, with post-EA with uterine adhesions, can lead to failure of endometrial collection and other modalities, masking endometrial pathology. The hysteroscopic technique is a better choice to exclude malignant endometrial lesions in such patients. Advantages of hysteroscopy: The entire uterine cavity can be viewed directly during the examination, and tissue biopsy can be performed directly on the suspected lesions, reducing the risk of missing lesions.
