Abstract
BackgroundContemporary surgical training can be compromised by fewer practical opportunities. Simulation can fill this gap to optimize skills' development and progress monitoring. A structured virtual reality (VR) laparoscopic sigmoid colectomy curriculum is constructed and its validity and outcomes assessed. MethodsParameters and thresholds were defined by analysing the performance of six expert surgeons completing the relevant module on the LAP Mentor simulator. Fourteen surgical trainees followed the curriculum, performance being recorded and analysed. Evidence of validity was assessed. ResultsTime to complete procedure, number of movements of right and left instrument, and total path length of right and left instrument movements demonstrated evidence of validity and clear learning curves, with a median of 14 attempts needed to complete the curriculum. ConclusionsA structured curriculum is proposed for training in laparoscopic sigmoid colectomy in a VR environment based on objective metrics in addition to expert consensus. Validity has been demonstrated for some key metrics.
