Abstract:The traditional way of teaching a resident is education in a clinical setting from a supervisor. However, since the time a surgeon has to train a resident is reduced and training should be in a cost-effective manner, new ways of teaching should be developed. The goal of this study is to develop a newway to teach novices endoscopic skills by means of a serious game. The game will focus on navigating with the endoscope through the game, reproducing the psychomotor skills required for the performance of a good endoscopic procedure. The movement of the endoscopist will be measured by means of the Xsens motion tracking system and the endoscope will be tracked by the NDI Aurora tracking system during a diagnostic gastroscopy. The procedure will be performed on a porcine model, a silicone model and in the clinical setting. The movement of the left hand, sternum movement, smoothness of movement and procedure time of the endoscopist will be compared between novices and experts. The measured Xsens data will be used to animate the experts movement in the simulation part of the serious game. The BN055 IMU sensor together with the Aurora tracking system will be used for implementation of movement of the endoscope inside the game part of the serious game. The experts move their left hand more gradually and controlled compared to the novices, there is also more controlled torque of the endoscope shaft compared to the novices, which could result in less patient discomfort. When the porcine and silicone model are compared to the clinical trial setting, there are differences in the left hand movement. The recorded data can be used for a simulation of the procedure, however, the Xsens suit is giving more information then can be implemented into the physical endoscope for the game part of the serious game. Measuring the BN055 IMU sensor to the scope handle combined with the Aurora tracking sensor can be directly translated into the game part of the serious game. The clinical trial measurements shows a different movement of the left hand compared to both the models. To make the simulation more realistic, clinical trial measurements are of importance. The upper body movements can be recorded and reconstructed in a simulation showing the novice how to move. However, for the game part, the movement of the endoscope handle relative to the endoscope shaft are important. No clinical trial measurement is needed for implementation in the game part of the serious game.
