MP34-02 EVALUATION OF THE MICROSOFT HOLOLENS IN SURGICAL TRAINING OF UROLOGICAL LAPAROSCOPIC SKILLS

Abstract

INTRODUCTION AND OBJECTIVE: Literature indicates that most laparoscopic procedures are associated with a 'learning phase' in which the incidence of serious complications is significantly increased. It has been identified that this 'early' or 'learning' phase can be acquired outside the operating theatre, thus making laparoscopy ideal for simulation-based training. The Microsoft HoloLens is a novel mixed reality head-mounted display that, to date, has not been extensively researched. This study aims to evaluate the use of the HoloLens as a training tool for basic laparoscopic skills and assess its impact on the learning curve of participants. METHOD(S): 40 novices were randomly assigned to either the interventional group, who used the HoloLens, or the control group, who used the conventional laparoscopic monitors and stack system. The HoloLens replaced the monitor, allowing the user to see a holographic overlay of the laparoscopic image. They could adjust screen size, positioning and closeness, as well as personalise their surroundings. Each participant was required to complete ten sessions in which they performed four tasks taken from the validated E-BLUS curriculum. A performance improvement score was recorded and learning curves for the four tasks were mapped. A comprehensive evaluation survey concerning the HoloLens was also distributed and completed for analysis. RESULT(S): No statistical significance was demonstrated in the number of sessions needed to reach proficiency for the peg transfer (p =0.12), circle cutting (p=0.38) and needle guidance tasks (p=0.23). There was however a steeper learning curve for the suturing task. Users reached their target performance in significantly fewer sessions when using the HoloLens compared to conventional methods (4.6 +/- 1.6 vs 6.5 +/- 1.75, p=0.045). More than 95% of participants agreed or strongly agreed that the HoloLens has a potential role within surgical education. CONCLUSION(S): Across the four tasks, participants using the HoloLens demonstrated significantly faster acquisition of laparoscopic suturing. Through re-alignment of the visual-motor axis the HoloLens provides ergonomic benefits to its users. The HoloLens, with its portable design and personalised learning environment, could provide a fantastic alternative to the more cumbersome training monitors currently used. Logistical factors, including comfort and battery life, need to be addressed for this device to reach its full potential.
