Abstract
BACKGROUND: Novice surgeons experience high levels of physical and mental workload during the early stages of their curriculum and clinical practice. Laparoscopic sleeve gastrectomy is the first bariatric procedure worldwide. Feasibility and safety of single-port sleeve gastrectomy (SPSG) has been demonstrated. An immersive virtual reality (VR) simulation was developed to provide a repetitive exercise to learn this novel technique. The primary objective of this study was to evaluate the impact of the VR training tool on mental and physical workload in novice surgeons. The secondary objective included an evaluation of the VR simulator. METHODS: A monocentric-controlled trial was conducted. Ten participants were divided into two groups, the VR group and the control group (without VR training). Surgery residents participated in a first real case of SPSG and a second case 1 month later. The VR group underwent a VR training between the two surgeries. Mental and physical loads were assessed with self-assessment questionnaires: NASA-TLX, Borg scale, and manikin discomfort test. The VR simulator was evaluated through presence, cybersickness, and usability questionnaires. RESULTS: This study showed a decrease of the mental demand and effort dimensions of NASA-TLX between the first and the second surgery in the VR group (P < .05). During the second surgery, a marginally significant difference was shown concerning the mental demand between the two groups. Postural discomfort of the VR group decreased with practice (P < .01), mainly between the first and the second surgery (P < .05). Furthermore, participants characterized the VR simulator as realistic, usable, and very useful to learned surgery. CONCLUSION: This exploratory study showed an improvement in mental and physical workload when novice surgeons trained with VR (repetitive practice, gesture improvement, reduction of stress, etc.). Virtual reality appears to be a promising perspective for surgical training.
