Introduction• Surgical simulation brought to the forefront of
surgical training– Technological advances– Importance of surgical safety– Limitation in surgical trainee exposure
• EWTD• Duty hour restrictions
• Abundance of laparoscopic/ endovascular simulators
• Development of Hernia Repair Open Surgical Simulation (HeROSS) model

Conclusions• Statistically significant Improvement in
anatomical and procedural knowledge from using the interactive simulation model
• Vital role of simulation as an adjunct in modern surgical training
• Open surgical procedural knowledge a pre-requisite to laparoscopic surgery
• Envisage online virtual theatre with ability to do multiple core index procedures
