目的 探讨 3D(三维重建技术)成像系统在住院医师规范化培训(简称住培)医师肝脏Couinaud分段教学中的价值.方法 选取 2020 年 7 月—2022 年 6 月西安交通大学第二附属医院普通外科 60 名住培医师作为研究对象,随机分为对照组(n=20)、试验组 1(n=20)和试验组 2(n=20).对照组采用阅读CT二维图像进行Couinaud分段教学;试验组 1 先二维图像后三维图像进行此教学;试验组 2 先三维图像后二维图像进行此教学.住培医师对Couinaud分段和满意度进行评价.结果 试验组 1 和试验组 2 Couinaud分段 8 段的准确率优于对照组,差异有统计学意义(P＜0.001);试验组 1 和试验组 2 回答所有问题所需的时间[(10.80±1.94)min、(8.60±1.79)min]少于对照组[(16.45±1.76)min],且两试验组对比,差异有统计学意义(P＜0.05).试验组 1 和试验组 2 对Couinaud分段理解度及教学方法满意度高于对照组,差异有统计学意义(P＜0.001).结论 基于 3D成像系统的教学方法,可提升住培医师对肝脏Couinaud分段为基础的肝脏解剖的理解能力和实践能力,取得满意的教学效果.
Application of 3D Visualization Imaging System in Standardized Residency Training of Learning Liver Couinaud Segment
Objective To investigate the value of three-dimensional(3D)reconstruction visualization technology in standardized residency training of learning liver Couinaud segment.Methods From July 2020 to June 2022,a total of 60 standardized residency training residents from the department of general surgery in the Second Affiliated Hospital of Xi'an Jiaotong University were selected and randomly divided into control group(n=20),test group 1(n=20)and test group 2(n=20).In the control group,reading of CT or MRI images combined with surgical videos were used for learning the liver Couinaud segment;In test group 1,the liver CT and MRI were read first,then the 3D images and the videos were used.In test group 2,the 3D images were read first,then the CT and MRI and the videos were used.After the training,important vessels of liver,Couinaud segmentation and satisfaction were evaluated using the evaluation scores and questionnaires.Results The accuracy of Couinaud paragraph 8 in experimental group 1 and experimental group 2 was better than that in control group,and the difference was statistically significant(P＜0.05).The time required for trial groups 1 and 2 to answer all questions[(10.80±1.94)min;(8.60±1.79)min]was less than the control group[(16.45±1.76)min],and the difference between the two experimental groups was statistically significant(P＜0.05).The understanding degree of Couinaud segment and the satisfaction degree of teaching method in experimental group 1 and experimental group 2 were higher than those in control group,and the difference was statistically significant(P＜0.001).Conclusion The teaching method based on 3D technology can improve the understanding and practice ability of standardized residency training residents on the liver Counaud segment,and achieve satisfactory teaching results.
