Objectives: To develop a robotic technique for extraperitoneal aortic lymphadenectomy in cadavers followed by application in a patient with advanced cervical cancer.
Methods: Two fresh frozen female torso cadavers were used to develop the correct placement of the robotic column and trocars, respectively, to allow for a safe and adequate performance of aortic lymphadenectomy using the da Vinci S system. The resulting technique was applied to a patient with cervical cancer Stage IB2 presenting with enlarged aortic nodes.
Results: Appropriate sites for trocar and robotic column placement were identified in the female cadavers. In the patient, the operating, docking, and console times were 103, 3.5, and 49 minutes, respectively. The blood loss was 30 ml. Selective removal of 5 enlarged aortic nodes revealed no evidence of metastases.
Conclusion: Robotic extraperitoneal aortic lymphadenectomy is feasible provided there is proper robotic trocar and column placement. The operating time and number of aortic nodes selectively removed by robotics in this patient are within the range of those reported with an extraperitoneal systematic aortic lymphadenectomy by laparoscopy.

Impact of the Number of Positive Pelvic Lymph Nodes on Risk of Para-Aortic Recurrence in Patients with Clinically Early Cervical Cancer Treated by a Radical Hysterectomy and Pelvic Lymphadenectomy.

Background: Guidelines recommend the extension of the pelvic radiotherapy volume to the para-aortic region in locally advanced cervical cancer and ≥3 suspicious pelvic lymph nodes (PLN) on imaging. Whether this recommendation is also valid for clinically early stages is uncertain. The objective of this study was to investigate the para-aortic (PAO) lymph node recurrence rate in patients with early-stage cervical cancer, ≥3 metastatic PLN, and negative common iliac nodes after a radical hysterectomy followed by pelvic (chemo)radiotherapy without extension to the PAO region.

Upper para-aortic lymph node dissection (PALND) is one of the most challenging gynecologic robotic procedures. This study aimed to evaluate the oncologic and operative outcomes of robotic staging surgery, including upper PALND, using low pelvic port placement (LP3) in 22 patients with high-risk endometrial cancer. High-risk was defined as patients who showed deep myometrial invasion with grade III, cervical involvement, or high-risk histology.

Background: The standard for robotic para-aortic lymphadenectomy has not been fully established. Para-aortic lymphadenectomy performed by sharing the same ports with pelvic procedures, a procedure known as dual-docking surgery, can be performed using the latest robotic system. We prospectively examined the ability of standardized dual-docking robotic surgery in endometrial cancer patients.

Objective: The primary objective of this study was to identify the risk of metastasis to lymph nodes above the inferior mesenteric artery (IMA) in endometrioid-type endometrial cancer (EC) and the factors that influence metastasis.
Methods: The study included patients who had been operated on for endometrioid-type EC in three gynecological oncology centers between 2007 and 2023. The supramesenteric lymph node (SM-LN) is the region between the left renal vein and the IMA, whereas the inframesenteric lymph node (IM-LN) is the region between the IMA and the aortic bifurcation, as determined by the level of the IMA.
