What is the prognosis of subtotal hysterectomy for the treatment of functional uterine bleeding?

Surgery is the ultimate weapon for treating functional uterine bleeding, and it is also the last resort when other methods of treating menorrhagia are ineffective. Depending on whether the cervix is ​​preserved, hysterectomy is divided into total hysterectomy and subtotal hysterectomy. These two methods can be selected based on comprehensive considerations such as the patient's age, physical condition, uterine size, and pelvic condition.

Subtotal hysterectomy is the earliest hysterectomy procedure, which is simple to operate and has few complications. As early as the 1950s, its usage rate accounted for 95% of all hysterectomies. Later, in order to avoid the occurrence of cervical stump cancer, total hysterectomy gradually replaced the monopoly of subtotal hysterectomy. Now, with the improvement of cervical cancer screening methods, the decrease in the incidence of cervical stump cancer (0.11%~0.14%), and the general improvement of people's requirements for quality of life, subtotal hysterectomy has gradually received attention. Bojahr et al. in Germany reviewed and analyzed 1604 cases of laparoscopic subtotal hysterectomy (LSH) and believed that subtotal hysterectomy is easy to operate, has low postoperative morbidity, and has little damage to the bladder and pelvic floor nerves. It can maintain good bladder function and sexual function after surgery. Therefore, subtotal hysterectomy is considered to be the best procedure for hysterectomy. There are also many reports in China. At present, it is generally accepted that subtotal hysterectomy should be used for benign uterine lesions when potential malignant or other serious cervical lesions are excluded, and follow-up should be strengthened after surgery.
