摘要
目的探讨三维重建结合胸部CT对低年资胸外科医师手术教学中的应用效果。方法采用自身对照研究,研究时间为2018年7月-2021年10月,研究对象为28位低年资胸外科医师。以10套试卷评估学员的基线,每套试卷5道题,分别关于病灶位置、肺动脉、段间肺静脉、所属支气管及变异、手术设计。采用三维重建结合CT进行教学,教授学员了解肺亚段血管、支气管在CT上的位置,引导学生在脑海中进行虚拟三维重建,并在手术中验证。教学后进行理论测试和自我评价。结果教学前基线分数为(54.1±5.2),教学后为(68.6±5.1)(P<0.001)。主要失分题目为肺动脉、静脉的判断。经过教学后,学员可以在胸部平扫薄层CT上辨别肺亚段动静脉。双肺下叶静脉和支气管是教学的难点。学员自我评价肺血管三维重建较传统CT教学效果更好,学习更快。结论采用三维重建方法可以提高学员CT阅片水平和对手术的理解,值得进一步推广。
Objective To explore the effect of three-dimensional(3D)reconstruction combined with chest computed tomography(CT)in the operation teaching of junior thoracic surgeons.Methods A self-control study was conducted.The subjects were 28 junior thoracic surgeons from July 2018 to October 2021.Ten sets of test papers were used to evaluate the baseline of students.Each set of test papers had 5 questions about the location of lesions,pulmonary artery,pulmonary vein,bronchus and variation,and surgical design.Using 3D reconstruction combined with CT to teach students understanding the position of pulmonary segmental vessels and bronchus on CT.Guide students to imagine virtual 3D reconstruction model in their mind and verify it in surgery.Theoretical test and self-evaluation were carried out after teaching.Results The baseline score before teaching was(54.1±5.2)and after teaching was(68.6±5.1)(P<0.001).The main loss of points was the judgment of pulmonary artery and vein.After teaching,students can identify pulmonary segmental arteries and veins on thin-layer chest CT.Veins and bronchus of bilateral lower lobe are difficult points in teaching.The students evaluated that the effect of 3D reconstruction of pulmonary vessels was better and faster than that of traditional CT teaching.Conelusion The use of 3D reconstruction method can improve the students'CT reading level and understanding of surgery,which is worthy of further promotion.
