Abstract
The aim of this study is to determine the learning curve for basic robotic surgical skills and if it is influenced by prior laparoscopic surgical skills. We designed a workshop with 40 participants, divided into four groups, 10 participants each: Group 1 with fifth and sixth year medical students (S), Group 2 with second and third year surgical residents (R2-3), Group 3 with fifth and sixth year surgical residents(R5-6) and Group 4 with young attending surgeons (AS). S group had no prior training in minimally invasive surgery, while the remaining three groups, allthough without prior training in robotic surgery, had experience in laparoscopic surgery according to their current current medical training level. The theoretical part was comprised of four courses lasting one hour each, over a period of ten days and one lecture with a duration of two hours with practical exemplification using the da Vinci® Xi surgical system (Intuitive Surgical®) and dV-Trainer® (MIMIC Technologies®), for each of the four groups. The practical part was comprised of two exercises: Peg Board 1 (PB1) and Vertical Defect Suturing (VDF). Results were analyzed via the data automatically generated by the simulator, and the aim for completion of training was set at a score of 90% or above for each exercise. We recorded two variables: total time (minutes) spent on the simulator and number of tries needed in order to reach this score. Statistical analysis showed no significant differences beetween the R2-3 and R5-6 groups for both variables, on both exercises. The S group’s results were significantly better PB1 regarding both variables (p < 0.05), while the AS group had significantly better results for both variables on VDF (p < 0.05). There were no other statistically significant differences. The time spent on the simulator for completion of the workshop had a median value of 39 minutes, while the number of tries had a median of 23. We conclude that the learning curve for mastering basic robotic surgical skills is 23 tries and is significantly influenced by prior skill level in laparoscopic surgery.
