To discuss the feasibility, safety and practicability of da Vinci robot-assisted para-aortic lymphadenectomy in cervical cancer surgical staging.And analysis the risk factors of para-aortic lymph node metastasis.

A retrospective analysis was made on the clinical data of 60 cases of stage ⅢC1r cervical squamous cell carcinoma patients in the gynecologic oncology center of the Chongqing University from Mar. to Jul. 2020 who undergoing para-aortic lymphadenectomy. 25 cases undergoing robot para-aortic lymphadenectomy(robot group)and 35 cases undergoing laparoscopic para-aortic lymphadenectomy(laparoscopic group).

The operation time were(97.60±5.440)min and(168.00±12.394)min, the operation blood loss were(5.88±2.023)ml and(111.70±13.186)ml, the removed lymph nodes numbers were(8.32±1.545)and(7.37±0.897), the time to start radiation and chemotherapy after surgery were(11.08±0.812)d and(13.20±0.711)d, the surgical complication rate were 4.0%, 8.5% in robot group and laparoscopic group.The operation time and the operation blood loss, the differenct was statistically significant(P<0.05). Univariate analysis showed that the clinical stage was associated with para-aortic lymph node metastasis, and the higher the stage, the greater the risk of lymph node metastasis(χ²=11.295, P<0.05).

There are advantages to robot-assisted para-aortic lymphadenectomy for cervical cancer surgical staging. Patients have less bleeding, short operation time, rapid recovery.The higher the clinical stages of cervical cancer, the greater the risk of lymph node metastasis.Surgical staging has clinical significance and provides a basis for the follow-up precise radiotherapy.
