Simulation-Based Training Using the “Sechenov” Virtual Platform in Gastrointestinal Surgery

Aim: to evaluate the effectiveness of educational technology using virtual reality in abdominal surgery.
Materials and methods. The study was conducted using the domestic virtual reality platform “Sechenov” and abdominal surgery simulators. When launching the software modules “Operation — Cholecystectomy” and “Operation — Gastric Resection”, an anatomical model of a human body with detailed internal organs of the abdominal cavity appears next to the user, and it has an anchor point in the center of the location. The tasks are completed through the assessment of the results of the survey of students using the Likert system, as well as several open clarifying questions. Based on the results of the analysis, two groups were formed: those students who had no experience working with virtual systems and students who had previous experience working in virtual reality simulators, including cases of rehabilitation after injuries.
Results. When analyzing the ergonomics of simulator control depending on the experience of using virtual reality outside of educational purposes, it was not possible to establish statistically significant differences (p = 0.393). However, depending on the experience of using virtual simulators for educational purposes, statistically significant differences were established (p = 0.014). When comparing data on satisfaction with participation in training depending on the experience of using virtual reality outside of educational purposes, no significant differences were found (p = 0.875). When analyzing the educational value of the teaching methodology depending on previous experience using virtual simulators, statistically significant differences were found (p = 0.023).
Conclusions. The virtual reality simulator in abdominal surgery provides the opportunity to add new educational scenarios; reduces the fear of mistakes in students; not only allows for training in manipulations but also serves as a teaching aid on the clinical anatomy of the stomach and hepatobiliary complex.
