In general, hysteroscopic mediastinectomy is currently the treatment of choice for uterine mediastinum. Before hysteroscopic mediastinectomy is performed, all relevant tests are required, such as blood count, coagulation routine, liver and kidney function, electrocardiogram, ultrasound and leukorrhea routine. General anesthesia is required for the operation and routine sterilization is performed before the operation. During the operation, it is necessary to use cervical forceps to hold the cervix forward and outward, dilate the cervix and then insert the hysteroscope, turn on the light source and inject the bulking agent, wait until the uterine cavity fills up and then rotate the mirror to follow the sequence of observation, and then remove the longitudinal septum and stop bleeding by ironing, and if there is no active bleeding, the operation will be finished. It is recommended to go to a hospital with sophisticated diagnostic and treatment technology and choose a professional doctor for the treatment when undergoing mediastinopexy.
