Benign tumors of the uterus are common tumors of the female reproductive system, and their incidence is increasing every year. Total hysterectomy can be divided into extrafascial and intrafascial hysterectomy. Total hysterectomy and subtotal hysterectomy are methods of treating benign uterine diseases. The possibility of cervical stump cancer exists with subtotal hysterectomy, and the quality of life decreases after total hysterectomy. With the improvement of living standards, patients’ requirements for postoperative quality of life have also gradually increased. Total hysterectomy and subtotal hysterectomy have their own advantages and disadvantages. The modified intrafascial hysterectomy can achieve the purpose of total hysterectomy and also have some advantages of subtotal hysterectomy. For a long time, the knowledge of cervical fascia has made it difficult to promote intrafascial hysterectomy. Histologically, the cervix is mainly composed of fibrous connective tissue, with only a small amount of smooth muscle migrating with the muscle tissue of the uterine body, with clear boundaries. The fibroblasts in the wall of the uterine cervix were gradually arranged tightly from the inside to the outside, and the staining became lighter and darker, and the outer layer of the fibroblasts was irregularly arranged with 1-2 mm dense fibroblasts. The uterine and vaginal fascia was actually a continuous fibrous sheath formed by dense fibroblasts, which originated from the fascia of the pelvic septum, was thin and inconspicuous in the uterine body, and became thickened and strong around the uterine cervix, and its two wings were thickened outward to continue as the main ligament of the uterus and the sacral ligament. Based on the above histological features, the modified intrafascial total hysterectomy has the following advantages: ① It does not require adequate separation of the bladder and generally does not injure the bladder intraoperatively. ② The treatment of the main uterine ligament, sacral ligament, parametrial and paravaginal tissues is reduced, ureteral injury is avoided, and the operation time is significantly shortened. The main ligament of the uterus, sacral ligament and fascia are preserved to form a new central tendon, which maintains the support structure of the pelvic floor and keeps the other organs in normal position, and prevents the loosening and prolapse of the pelvic floor tissue. ④ Small surgical invasion, less bleeding, especially small bladder dissection surface, less hematoma and infection, and lower postoperative fever rate. ⑤ The lower branch of uterine artery is not severed and the pelvic floor plexus is less damaged, which is conducive to the healing of the vaginal stump, reduces local inflammatory reaction and postoperative bleeding, ensures the integrity of the vaginal blood supply system, and has less impact on sexual function. This procedure is simple, short operation time, less bleeding, less collateral damage, quick recovery, less impact on sexual life, and can improve the quality of life, so it has clinical promotion value.
