“…Motion analysis systems are next-generation systems for evaluating surgical performance. The Imperial College Surgical Assessment Device [12,13,14,15] and the Hiroshima University Endoscopic Surgical Assessment Device are representative motion analysis systems [16,17,18] that have already demonstrated construct validity.…”

Objective: The aim of this study was to determine whether any correlation exists between the performance of the Mimic® dV-Trainer (Mimic Technologies, Seattle, Wash., USA) and the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, Calif., USA). Methods: Twelve participants were recruited, ranging from residents to consultants. We used four training tasks, consisting of ‘Pick and Place', ‘Peg Board', ‘Thread the Rings' and ‘Suture Sponge', from the software program of the Mimic dV-Trainer. The performance of the participants was recorded and measured. Additionally, we prepared the same tasks for the da Vinci Surgical System. All participants completed the tasks using the da Vinci Surgical System and were assessed according to time, the Objective Structured Assessment of Technical Skill checklist and the global rating score for endoscopic suturing assessed by two independent blinded observers. After performing these tasks, the participants completed a questionnaire that evaluated the Mimic dV-Trainer's face and content validity. The final results for each participant for the Mimic dV-Trainer and the da Vinci Surgical System were compared. Results: All participants ranked the Mimic dV-Trainer as a realistic training platform that is useful for residency training. There was a significant relationship between the Mimic dV-Trainer and the da Vinci Surgical System in all four tasks. We verified the reliability of the assessment of the checklist and the global rating scores for endoscopic suturing assessed by the two blinded observers using Cronbach's alpha test (r = 0.803, 0.891). Conclusions: We evaluated the concurrent validity of the Mimic dV-Trainer and the da Vinci Surgical System. Our results suggest the possibility that training using the Mimic dV-Trainer may therefore be able to improve the operator's performance during live robot-assisted surgery.

“…The lack of realism is covered by physical (11,12) and hybrid simulators (13), which also implement automatic tools for the objective assessment of technical skills. Finally, another attempt to develop more automatic objective evaluation methods are the systems based on the motion analysis of surgical instruments (14)(15)(16).…”

Minimally invasive surgery is a highly demanding surgical approach regarding technical requirements for the surgeon, who must be trained in order to perform a safe surgical intervention. Traditional surgical education in minimally invasive surgery is commonly based on subjective criteria to quantify and evaluate surgical abilities, which could be potentially unsafe for the patient. Authors, surgeons and associations are increasingly demanding the development of more objective assessment tools that can accredit surgeons as technically competent. This paper describes the state of the art in objective assessment methods of surgical skills. It gives an overview on assessment systems based on structured checklists and rating scales, surgical simulators, and instrument motion analysis. As a future work, an objective and automatic assessment method of surgical skills should be standardized as a means towards proficiency-based curricula for training in laparoscopic surgery and its certification.
