Endometrial ablation, or endometrial ablation, is a procedure used to treat uterine bleeding by generating a localized thermal effect through instruments that act on the endometrial and superficial muscular layers of the uterus. Endometrial ablation is a procedure that destroys the inner lining of the uterus and is used to treat abnormal uterine bleeding. It causes a series of changes in the basal and functional layers of the endometrium, such as degeneration, necrosis, and shedding, thus solving the problem of abnormal uterine bleeding. At present, endometrial ablation is widely used in clinical practice. It is a minimally invasive surgery, which does not affect the appearance, has a high safety factor, a short operation time, and is less harmful, but side effects such as nausea and abnormal vaginal discharge may occur after the operation, which can be relieved after 1~2 weeks. Endometrial ablation also has certain surgical hazards, such as infertility, infection, etc. Patients with fertility requirements need to be treated with caution.
