Hysterectomy mainly involves removal of the uterus, cervix and adjacent tissues, which can be categorized into total hysterectomy, subtotal hysterectomy, extensive hysterectomy and sub-extensive hysterectomy according to the specific scope of its removal. 1. Total hysterectomy: it refers to a surgical method that does not preserve the cervix and removes all of the uterine body and cervix. It is suitable for women with uterine fibroids, precancerous lesions of the cervix, etc., who do not have any reproductive requirements, and can consider total hysterectomy. 2. Subtotal hysterectomy: It means only the uterus is removed and the cervix is preserved. It is suitable for patients with uterine fibroids, functional uterine bleeding, adenomyosis, etc. who require cervical preservation. 3. Extensive hysterectomy: as the basic surgical method for invasive carcinoma of the cervix, it includes all of the uterus of the uterine body and cervix, part of the vagina (i.e., more than 3cm under the fornix or more than 3cm under the cancerous lesion), both fallopian tubes, as well as the ovaries (or one side of the ovary is preserved), the superficial uterosacral ligament, as well as the lateral main ligament of the pelvic wall, the vesico-uterine cervical ligament, and the vaginal tissues. 4. Sub-extensive hysterectomy: It is a kind of surgery that preserves the cervix and removes the rest of the uterus; the scope of surgical resection is the body of the uterus, but the cervix is preserved. It is indicated for young women with functional uterine bleeding, fibroids, adenomas and other benign conditions, and requires that they do not have severe cervical pathology or that the patient is unable to tolerate other, larger procedures. If a woman suffers from certain conditions that require a hysterectomy, it is recommended that a surgical plan be developed based on the woman’s specific situation after a doctor’s visit.
