To improve visualization during minimal access surgery, a novel robotic camera has been developed. The prototype camera is totally insertable, has 5° of freedom, and is remotely controlled. This study compared the performance of laparoscopic surgeons using both a laparoscope and the robotic camera. The MISTELS (McGill Inanimate System for the Training and Evaluation of Laparoscopic Skill) tasks were used to test six laparoscopic fellows and attending surgeons. Half the surgeons used the laparoscope first and half used the robotic camera first. Total scores from the MISTELS sessions in which the laparoscope was used were compared with the sessions in which the robotic camera was used and then analyzed with a paired t test (P< .05 was considered significant). All six surgeons tested showed no significant difference in their MISTELS task performance on the robotic camera compared with the standard laparoscopic camera. The mean MISTELS score of 963 for all subjects who used a laparoscope and camera was not significantly different than the mean score of 904 for the robotic camera (P= .17). This new robotic camera prototype allows for equivalent performance on a validated laparoscopic assessment tool when compared with performance using a standard laparoscope.
