摘要: 目的 本研究旨在探索基于案例学习(case-based learning,CBL)联合三维影像重建技术在腹腔镜肾部分切除术教学中的应用效果,为优化该术式培训方案提供实证参考。方法 选取 2024年1月至2025年6月在郑州大学第一附属医院泌尿外科培训的59名进修医师为研究对象,按照培训时间顺序分为试验组(28名医师)和对照组(31名医师),分别实施CBL联合三维影像重建教学和传统幻灯+手术视频教学。通过理论考核、病例分析及课程满意率问卷调查等方式评估教学效果。采用t检验、 χ2检验等方法分析数据。结果 试验组医师理论考核成绩[(88.32±5.66)分]、病例分析优秀率[75.0%(21/28)]均高于对照组医师[(81.29±7.22)分、22.6%(7/31)],其差异均具有统计学意义(均P<0.01)。试验组医师在“课程合理性”“内容实用性”“综合评价”3个维度的“非常满意”率分别为71.4%(20/28)、64.3%(18/28)、78.6%(22/28),均高于对照组医师[25.8%(8/31)、16.1%(5/31)、38.7%(12/31)],其差异均具有统计学意义(均P<0.01)。结论 CBL联合三维影像重建技术可以通过解剖可视化与临床思维培养的协同作用,提升腹腔镜肾部分切除术教学效果,值得作为优选培训方案推广。

Abstract: Objective To explore the application effect of case-based learning (CBL) combined with three-dimensional (3D) imaging reconstruction technology in the teaching of laparoscopic partial nephrectomy, and to provide empirical evidence for optimizing the training program for this surgical procedure. Methods A total of 59 visiting physicians from the Department of Urology at The First Affiliated Hospital of Zhengzhou University from January 2024 to June 2025 were selected as the study subjects. They were divided into a experimental group (28) and a control group (31) according to the chronological order of their training. The experimental group received CBL combined with 3D imaging reconstruction teaching, while the control group received traditional teaching using slides and surgical videos. Teaching effectiveness was evaluated through theoretical assessments, case analyses, and a course satisfaction questionnaire. Data were analyzed using t-tests and Chi-square tests. Results The experimental group showed higher theoretical assessment scores [(88.32±5.66) points] and excellence rate in case analysis [75.0% (21/28)] compared to the control group [(81.29±7.22) points, 22.6% (7/31)], both P<0.01. Regarding course satisfaction, the ″very satisfied″ rates in the experimental group for the three dimensions of ″course rationality″, ″content practicality″, and ″comprehensive evaluation″ were 71.4% (20/28), 64.3% (18/28), and 78.6% (22/28), respectively. These rates were higher than those in the control group [25.8% (8/31), 16.1% (5/31), and 38.7% (12/31)], all P<0.01. Conclusions CBL combined with 3D imaging reconstruction technology can enhance the teaching effectiveness of laparoscopic partial nephrectomy through the synergy between anatomical visualization and the cultivation of clinical thinking. It is recommended as a preferred training program for promotion.
