Cervical cancer is the second most prevalent malignant tumor in women. The concept of surgical treatment for cervical cancer is changing toward improving the efficacy while minimizing patient trauma; single- or multi-drug adjuvant chemotherapy based on cisplatin can significantly improve patient survival, and the development of new targeted drugs has also achieved encouraging results. In order to improve the survival quality of patients, gynecologic oncologists have started to focus on the improvement of radical surgery without affecting the cure rate of patients, so as to preserve the fertility function, ovarian function, sexual function and pelvic floor function of patients to the greatest extent. Surgery to preserve fertility With the younger age of cervical cancer, 50% of patients are younger than 50 years old, and the 5-year survival rate of early cervical cancer patients can reach 88-97%, more and more patients desire to have children. Currently, the main surgical procedures to preserve fertility are: (1) laparoscopic radical cervical hysterectomy combined with pelvic lymph node dissection; (2) transabdominal radical hysterectomy combined with pelvic lymph node dissection. Although the procedure has been performed for many years, overall the postoperative pregnancy rate is only about 40%, and laparoscopic radical cervical hysterectomy is superior to the few open surgical routes. In addition, several small samples have shown that cervical conization with or without chemotherapy is safe and feasible for stage Ia1 patients with close follow-up. 2 , radical surgery with preservation of pelvic autonomic nerves (NSRH) The incidence of bladder dysfunction after RH is as high as 75-80%, and long-term pelvic floor-related dysfunction can exist in 20% of patients. In the 1980s, Sakamoto et al. pioneered the “Tokyo procedure” to preserve the autonomic nerve, in which the main ligament is divided into a vascular part and a neurological part, and only the vascular part is removed during surgery while the neurological part is preserved, thus allowing complete preservation of the bladder and rectal function. This procedure is mainly suitable for patients with stage Ib1 tumor diameter and stage Ib2-IIa after neoadjuvant chemotherapy. In recent years, the main advances in this procedure have been the identification of the infra-abdominal nerve and the deep uterine vein, as well as the use of laparoscopic nerve navigation systems, electrical stimulation, liposuction, ultrasound emulsification, and other methods to separate the intrapelvic tissues. Prospective randomized controlled studies have confirmed that this procedure significantly improves postoperative related symptoms in stage Ib2 and stage IIa patients. The key to this technique is the preservation of the pelvic autonomic nerves without compromising prognosis. However, it is still controversial whether the procedure itself increases recurrence because it reduces the extent of resection of the parametrium, the main ligament and the deeper part of the uterosacral ligament. 3 .Laparoscopic surgery with preservation of function Laparoscopic surgery for cervical cancer was first reported in the 1980s and was soon widely used in clinical practice because of its minimal injury and rapid recovery. A large number of prospective studies have shown that patients undergoing laparoscopic surgery have a significant advantage in terms of blood loss and hospitalization time compared with open surgery. Most scholars believe that laparoscopic surgery should be recommended for those patients who have no high-risk factors in the early stages. Laparoscopic preserved-function radical cervical cancer surgery has more advantages and better surgical results than open surgery because of less intraoperative bleeding and clearer visual field exposure, especially the magnification of nerves and blood vessels by the mirror, which can expose the nerves and pelvic floor vascular alignment more clearly. However, compared to open surgery, laparoscopic surgery has its own complications such as air embolism, electrical burns and tumor metastasis at the puncture site. In addition, laparoscopy is also used for preoperative evaluation of patients with locally advanced cervical cancer or lymph node metastases. If intra-abdominal or multiple pelvic or retroperitoneal lymph node metastases are found during laparoscopy, chemotherapy or radiotherapy alone will be used instead of extended surgery.
