To assess the advantages of a surgeon-controlled robotic endoscope holder in gynecologic minimally invasive solo-surgery as compared with conventional assistance with a second surgeon.


One hundred gynecologic laparoscopies were consecutively allocated to surgery with either a robot as the surgical assistant or a conventional assistant surgeon. Total operation time, image stability, and frequency of corrective maneuvers of the camera, in addition to the surgeon's satisfaction regarding the ergonomics of the intervention, were recorded. All interventions were performed by the same surgeon. All laparoscopic surgery was classified as either easy or advanced surgery.


The image stability score was significantly higher (10 vs 7; P<0.001) and fewer corrective maneuvers of the robotic endoscope were necessary (1 vs 5; P<0.001) with the robotic laparoscope holder; in addition, the surgeon recorded a significantly higher satisfaction score for the ergonomics of the semi-active robot (10 vs 7; P<0.001).


The robot does not prolong total operation time and increases the surgeon's comfort by improving image stability and laparoscope handling. It could provide major benefit, especially in complex gynecologic laparoscopic surgery.
