背景：由于涉及复杂的盆腔解剖结构，直肠癌的盆腔外侧淋巴结清扫术是一项困难的技术。三维（3D）器官模型已经被引入作为在某些领域中学习解剖学的教育工具。在这项研究中，我们使用3D模型对参与者进行盆腔解剖学教育，并评估学习效率，将结果与使用传统教科书的结果进行比较。研究设计：这项研究是一项随机，对照，单中心试验，于2018年7月至2019年7月进行。共有102名参与者（34名医学生，34名住院医生和34名外科医生）入组。参与者被随机分配到3D模型组或教科书组。首先，他们完成了一个简短的测试，以确认他们的基础知识，然后再接受进一步的教育。结果：教育前，3D模型组与教材组的短期测验成绩无显著性差异，教育后，3D模型组与教材组的短期测验成绩无显著性差异。教育后，3D模型组学生的短期和长期测试成绩显著高于教科书组（短期检验; p = 0.05，长期检验; p = 0.03），居民（短期检验; p = 0.05，长期检验; p = 0.002），外科医生（短检验; p = 0.009，长检验; p <0.001）。在学习盆腔外侧淋巴结清扫所需的盆腔解剖结构时，使用3D盆腔模型优于使用教科书。(C)2019年美国外科医生学会爱思唯尔公司出版All rights reserved.
BACKGROUND: Lateral pelvic lymph node dissection for rectal cancer is a difficult technique due to the complex pelvic anatomy involved. Three-dimensional (3D) organ models have been introduced as education tools to study anatomy in some fields. In this study, we educated the participants about pelvic anatomy using a 3D model, and evaluated learning efficiency, comparing the outcomes with those using a traditional textbook.STUDY DESIGN: This study was a randomized, controlled, single-center trial conducted between July 2018 and July 2019. A total of 102 participants (34 medical students, 34 residents, and 34 surgeons) were enrolled. Participants were randomly assigned to the 3D model group or the textbook group. First, they completed a short test to confirm their basic knowledge before further education. After collocated education, they completed the same short test again and another long test to evaluate their learning outcomes.RESULTS: Before education, there was no significant difference in the short test scores between the 3D model group and the textbook group. After education, the short and long test scores of the 3D model group were significantly higher than those of the textbook group for students (short test; p = 0.05, long test; p = 0.03), residents (short test; p = 0.05, long test; p = 0.002), and surgeons (short test; p = 0.009, long test; p < 0.001).CONCLUSIONS: Using a 3D pelvic model is superior to using a textbook when learning pelvic anatomy required for lateral pelvic lymph node dissection.
