| Abstract | ObjectiveTo investigate the educational value of combining intraoperative explanations with laparoscopic surgical video reviews for teaching the local anatomy of the stomach.MethodsThirty resident physicians undergoing standardised training in our hospital, including undergraduate resident physicians and clinical-type postgraduates in surgery who had not participated in radical gastrectomy for gastric cancer, were selected as study subjects. They were randomly divided into an experimental group and a control group, with 15 participants in each group. The experimental group received instruction through intraoperative explanations combined with laparoscopic surgical video reviews, while the control group participated in surgery without additional instructional methods. After the teaching sessions, both groups underwent clinical practice assessments, theoretical examinations and evaluations of teaching satisfaction. The distribution of the data was assessed using the Shapiro-Wilk normality test along with Quantile-Quantile plots. Two-way analysis of variance was employed to evaluate the main effects and interaction effects of clinical practice scores across different groups and student types. Statistical power was examined through post hoc power analysis.ResultsThe clinical practice assessment results, theoretical examination scores and teaching satisfaction ratings of the experimental group were significantly higher than those of the control group, with all differences reaching statistical significance (p<0.05).ConclusionCombining intraoperative explanations with laparoscopic surgical video reviews for teaching local anatomy during distal gastrectomy is more effective than participation in surgery alone. This approach allows students to review surgical videos at their convenience, enhancing their understanding and mastery of local anatomical structures and significantly improving the quality of local anatomy education for resident physicians. |
