Comparison of gaze behaviour of trainee and experienced surgeons during laparoscopic gastric bypass

Eye tracking presents a novel tool that could be used to profile skill levels in surgery objectively. The primary aim of this study was to identify differences in gaze behaviour between expert and junior surgeons performing a laparoscopic Roux‐en‐Y gastric bypass (LRYGB) for obesity.
