Trainees in the Traditional trained group will have an e-learning didactic component (specifically on the steps of the procedure, clinical aspects of the procedure, published evidence etc) which they must complete before training by a procedure expert. On completion of the e-learning module the trainees will complete a summative assessment of their knowledge. The trainees will then be shown how and then trained to perform an emergency scenario where open conversion is necessary due to vessel injury during robotic surgery task. The scenario will be demonstrated initially by an expert and who will then proctor the trainees in the same technique.

Participants in the PBP trained group will follow the exact same e-learning didactic course as the Traditional trained group but the PBP group will be required to pass a test of procedure knowledge on TS before continuing to the robotic surgical training element. The trainees knowledge will be assessed in a formative and summative fashion. After the trainees initial assessment, procedure-specific and validated procedure metrics will be used to teach them the steps of the emergency undocking procedure, as well as the correct (and incorrect) way to perform it. The metrics will be used to give to the trainees performance feedback with specific advice on how they might improve their performance, in the regards of technical skills.

Performance of emergency scenario where open conversion is necessary due to vessel injury during robotic surgery on a dry lab model with Da Vinci robotic system

Proficiency level will be determined by objectively assessed, validated, binary performance operative metrics where the proficiency benchmark is defined on the mean of the objectively assessed performance of experienced practitioners.

The aim of this study is to report the main performance outcomes of the T-REC trial. The investigators will compare differences between four groups in performance level as assessed by binary performance metrics of an emergency scenario where open conversion is necessary due to vessel injury during robotic surgery on a dry lab model with Da Vinci robotic system.

The four groups deffers for the training methodology used (PBP vs traditional training). The dependant variables will be the i) time required to complete the procedure, ii) the number of procedure steps completed, iii) the number of errors made, iv) the number of critical errors made and whether the procedure was completed or not.

Satisfaction of a surgical trainee is often thought to be key for training quality and a predictor of good outcome of surgical training. At the end of the T-REC trial, all participants were asked to complete an online questionnaire where their satisfaction with the adopted training method was asked for using a Likert scale.

Hypothesis is that trainee's satisfaction does NOT correlate with training outcome and that satisfaction is NOT a good determinator of training quality.
