After routine disinfection of the vulva and vagina, the cervix is dilated one by one with a dilation rod, and after the cervical dilatation is completed, the mirror is sent to the uterine cavity through the vagina and cervix, and the uterus is dilated. The excised tissue was sent for histopathological examination. After completion of excision, the electrodes are returned to the electrosurgery scope and the intrauterine pressure is increased to check for residual endometrium, to reduce intrauterine pressure, and for bleeding spots, if any, by electrocoagulation with a cutting ring or roller ball electrode. Hysteroscopic electrosurgery, which has a magnifying effect on the observed lesion site, allows for intuitive and accurate removal of diseased tissue. The procedure is an advanced treatment with minimal damage to the most body and faster recovery of the body after surgery.
