A failed medical abortion requires the choice of hysterectomy or hysteroscopy depending on the patient’s condition, and there is no such thing as which is better. Hysteroscopy and purging are both types of gynecological operations, both of which have different modes of operation and indications. Hysteroscopy is a procedure in which a small mirror with a probe is passed from the vagina through the cervix into the uterine cavity, which is then filled with water in order to visualize the interior. The operator can visualize the inside of the uterine cavity and can diagnose diseases such as cervical cancer and endometrial cancer. There is no probe in the hysterectomy, but the pathological tissues or residual embryos in the uterine cavity are sucked out of the contents of the uterine cavity by using the principle of negative pressure suction, which is suitable for diseases such as early miscarriage and hyperemesis gravidarum. For patients who did not have a clean abortion with medication need to choose the appropriate surgery according to the situation in their own uterus. Patients who do not have a clean abortion need further treatment under the guidance of a specialized doctor.
