Since subtotal hysterectomy has the advantages of simple operation, less side injuries and comorbidities, preservation of the cervix so that the vagina is not shortened, and the secretion of mucus from the cervical canal is conducive to the maintenance of postoperative sexual life, it is favorable for young and middle-aged women to accept and has less psychological impact. Due to early sexual behavior and the increase of multiple partners, the incidence of cervical cancer in China has gradually increased in recent years, and it is obviously tending to be younger. It has been reported abroad that young women under 30 years of age account for 15% to 20% of cervical cancer patients. After hysterectomy, the anatomical relationship loses its normal state, which increases the difficulty of cervical surgery at the stump to different degrees. Therefore, the indications for subtotal hysterectomy should be strictly controlled and subtotal hysterectomy should be carefully selected. Summarizing the lessons learned, we suggest the following 5 points: 1. For patients over 40 years old who need hysterectomy, it is recommended that the cervix be removed together. For patients with multiple uterine fibroids and myometriosis, the lesions are likely to involve the cervix and the possibility of recurrence is high, so the choice of hysterectomy should be careful. 3. Detailed routine examination of the cervix should be performed before surgery, including vaginal smear, cervical scraping and cervical smear, liquid-based cytology of the cervical canal, detection and typing of HPV infection. If necessary, colposcopy + cervical biopsy will be performed to exclude the presence of occult cervical cancer. 4.For benign ovarian or uterine diseases that require hysterectomy, total hysterectomy is generally appropriate except for patients who are young, have heavy pelvic adhesions, have difficulties in surgical operation or are in poor general condition and need to shorten the operation time and for certain emergency operations. 5. In order to prevent and detect cervical stump cancer in time, follow-up visits should be strengthened after subtotal hysterectomy and cervical erosion, if any, should be treated. In conclusion, although cervical cancer has its clear cause of HPV infection and a long precancerous stage, detailed examination of the cervix before subtotal hysterectomy may reduce the occurrence of occult stump cancer, but the occurrence of true stump cancer is still related to the number of subtotal hysterectomies, therefore, it is advocated that patients over 45 years old, especially those without follow-up conditions, should undergo total hysterectomy or intrafascial total hysterectomy. Therefore, it is recommended that total hysterectomy or intra-fascicular total hysterectomy should be performed in patients over 45 years of age, especially those without follow-up conditions, while some literature reports that the occurrence of cervical stump cancer in patients older than 60 years of age accounts for only 12 or 5%. For patients with preserved cervix, close postoperative follow-up can detect early lesions of residual cervix.
