Introduction/Background Endometrial cancer is one of the most common gynecological neoplastic diseases in Poland. According to ESGO recommendations, simple hysterectomy with bilateral salpingoophorectomy and bilateral sentinel lymph node detection should be performed. However, completed pelvic and paraaortic lymphadenectomy is indicated in cases of high-risk endometrial cancer. Minimally invasive surgery is the method of choice. Nowadays, procedures assisted with robotic surgery are increasingly common.

The aim of the study was to compare completed pelvic and paraaortic lymphadenectomy performed by dual or single docking during robotic surgery assisted with the da Vinci X system.

Methodology The analysis was based only on 25 patients with high-risk endometrial cancer after completed pelvic and paraaortic lymphadenectomy with mean age 60.07±10.67 (range 34.69–83.23) years. Mean BMI was 28.4±5.62 (range 18–41.5) kg/m2. Mean duration of surgery was 196±0.02 (range 110–295) minutes. The analyzed population was divided into two groups: in one, a one-site docking operation was performed; the second underwent dual docking surgery.

Results Average numbers of removed pelvic and paraaortic lymph nodes were respectively 24.5±8.7 and 15.87±6.83 in the first group and 24.88±11.75 and 18.05±7.92 in the second. There were no significant differences between one-site and dual docking. The number of removed lymph nodes did not differ significantly according to type of docking, experience of surgeon, or use of Vessel Sealer. Number of lymph nodes retrieved correlated with BMI of patients (p<0.005). Duration of operation was not associated with type of docking, but it was significantly associated with previous surgery (p<0.005).

Conclusion Robotic surgery is a novel method of minimally invasive surgery. No difference was found between the two types of docking in quality of lymphadenectomy.
