ObjectiveTo preliminarily explore application and effectiveness of real-scene teaching based on a live demonstration system in hepatobiliary surgical training, using laparoscopic cholecystectomy (LC) as an example. MethodsFrom March 2023 to February 2024, 60 surgical residents undergoing a 4-month standardized residency training at the Liver Transplant Center of West China Hospital, Sichuan University, were randomly assigned into an observation group (n=30) and a control group (n=30) using a random number table. The observation group received real-scene surgical teaching based on the live demonstration system, while the control group received traditional teaching methods. At the end of the training, both groups underwent an operative assessment on LC and completed a resident satisfaction questionnaire. Operative assessment used critical view of safety (CVS) scoring to evaluate surgical safety. Resident satisfaction was assessed using a self-designed questionnaire covering five domains: stimulating the learning atmosphere, increasing learning engagement, improving surgical proficiency, enhancing the understanding of surgical complications, and recognition of the teaching model. The final results were categorized as positive or negative evaluations. The significance level was set at α=0.05. ResultsThe observation group had significantly higher CVS score than the control group [4.2±1.3 vs. (2.8±1.7), t=3.57, P=0.001]. All 60 questionnaires were collected, and the observation group reported significantly higher positive evaluations in improving surgical proficiency, enhancing the understanding of surgical complications, and recognition of the teaching model compared to the control group (P<0.05). There were no statistically significant differences between the two groups regarding positive evaluations for stimulating the learning atmosphere and increasing learning engagement (P>0.05). ConclusionThe results of this study suggest that the real-scene teaching model based on a live demonstration system demonstrates good effectiveness in hepatobiliary surgical training and can improve the quality of surgical teaching during standardized residency training for surgical residents.
