Comparison between 155 cases of robotic vs. 150 cases of open surgical staging for endometrial cancer

Abstract

Objective: To compare the outcomes of 155 cases of endometrial cancer who had robot-assisted surgical staging to 150 open cases. Methods: Retrospective chart review of cases of endometrial cancer that underwent staging two different ways by two surgeons at an academic institution. Results: Mean age was 62.4 years in the robotic arm and 65 (P = 0.04) in the open arm. Mean body mass index was 34.5 Kg/m 2 in the robotic arm and 33 Kg/m 2 in the open arm (P = 0.2). Pelvic and para-aortic lymph node dissection were performed in 94.8% and 67.7% of the robotic cases versus 95.3% and 74% of the open cases, respectively. Mean operative time was 127 min in the robotic arm, and 141 min in the open arm (P = 0.0001). Mean lymph node count was 20.3 in the robotic arm, and 20 in the open arm (P = 0.567). Mean estimated blood loss was 119 ml in the robotic arm and 185 in the open arm (P = 0.015). Mean hospital stay was 1.5 days in the robotic arm, and 4 days in the open arm (P = 0.0001). The incidence of postoperative ileus (0.6% vs. 10.7%, P = 0.0001), infections (5.2% vs. 24%, P = 0.0001), anemia/transfusion (1.3% vs. 7.7%, P = 0.005), and cardiopulmonary complications (3.2% vs.14.7%, P = 0.003) was significantly lower in the robotic arm vs. the open arm. There was one death in the robotic arm attributed to pre-existing cardiac condition. Conclusion: Robotic-assisted staging reaps the benefits of minimally invasive surgery without compromising the adequacy of the procedure.
