Impact of intraoperative explanation combined with surgical video review on anatomy learning in laparoscopic distal gastrectomy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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.
