Robotic-assisted Transperitoneal Infrarenal Para-aortic Lymphadenectomy for Gynecological Malignancies: Comparison with a Laparoscopic Approach

Background/Aim: We evaluated the clinical feasibility and surgical outcomes of robotic-assisted transperitoneal infrarenal para-aortic lymphadenectomy (TIPAL) in patients with gynecological malignancies. Patients and Methods: The perioperative outcomes in 90 patients with gynecological malignancies who underwent laparoscopic (n= 43) or robotic-assisted (n= 47) TIPAL were compared retrospectively. Results: The operative time for pelvic and total lymphadenectomy were significantly shorter in the robotic-assisted approach, whereas the time for infrarenal para-aortic lymphadenectomy did not differ statistically. In contrast, the number of infrarenal para-aortic lymph nodes was significantly higher in the robotic-assisted approach. We compared the time per retrieved lymph node in both approaches, and those for pelvic, infrarenal paraaortic, and total lymphadenectomy were significantly shorter in the robotic-assisted approach. Conclusion: In our study, the robotic-assisted TIPAL took less time to retrieve a lymph node than the laparoscopic approach. The robotic-assisted approach for TIPAL is feasible for the staging and treatment of patients with gynecological malignancies.
