| Description: |
Objectives Motion tracking tools have been used in the analysis of surgeons’ technical expertise and posture in simulated endoscopic surgery. But its use in humans in real-life robotic surgery is limited. We analysed the effect of surgeons’ ergonomics and posture on skill metrics for vascular dissection during anatomical pulmonary resection. Methods In this observational study of vascular dissection/division during segmentectomy or lobectomy, we analysed the inter-group differences of those with more than (group 1) and less than (group 2) 100 robotic resections. The rapid upper limb assessment (RULA) scale was used to estimate ergonomic risk. Operative performance and posture for RULA were measured using the Kinovea-0.9.5 system. Path length of moving instruments, instrument speed, time for task completion, and duration of instruments out of vision were calculated to objectively assess operator performance. Results Group 1 (expert) comprised 2 males and 1 female, aged 42-61 years. Group 2 (novice) comprised 4 males, aged 31-52 years. Sixty-seven patients underwent robotic anatomical resection using the da Vinci Xi robotic platform, with 180 pulmonary vessels isolations/divisions (Group 1 = 95 vs Group 2 = 85). Group 1 had significantly better RULA ergonomic scores (4.3 vs 4.7, P < .001) which was associated with higher speed (2.8 ± 0.8 vs 2.1 ± 0.2 cm/s, P < .001), shorter task completion time (388 ± 278 vs 520 ± 322 s, P = .001), and shorter duration of instruments out of vision (P < .001). There was no difference in path length (P = .8) and no significant correlation between RULA score and different parameters that assessed surgical performance. Conclusions Video motion tracking software is an effective and unobtrusive method to evaluate surgical ergonomics and performance in robotic surgery. Better ergonomics were associated with increased surgical experience and improved surgical performance. |
