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.
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.
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).
Using a 3D pelvic model is superior to using a textbook when learning pelvic anatomy required for lateral pelvic lymph node dissection.
由于涉及复杂的盆腔解剖结构，直肠癌的侧方盆腔淋巴结清扫术是一项困难的技术。三维（3D）器官模型已作为教育工具被引入，用于研究某些领域的解剖学。在这项研究中，我们使用 3D 模型对参与者进行盆腔解剖教育，并评估了学习效率，将结果与使用传统教科书的结果进行了比较。
这是一项于 2018 年 7 月至 2019 年 7 月期间进行的随机、对照、单中心试验。共纳入 102 名参与者（34 名医学生、34 名住院医师和 34 名外科医生）。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，然后再进行进一步的教育。在协作教育之后，他们再次完成了相同的简短测试和另一个长测试，以评估他们的学习成果。
在教育之前，3D 模型组和教科书组的简短测试分数没有显著差异。在教育之后，对于学生（简短测试；p = 0.05，长测试；p = 0.03）、住院医师（简短测试；p = 0.05，长测试；p = 0.02）和外科医生（简短测试；p = 0.009，长测试；p < 0.001），3D 模型组的简短和长测试分数均显著高于教科书组。
在学习侧方盆腔淋巴结清扫术所需的盆腔解剖学知识时，使用 3D 骨盆模型优于使用教科书。
