Abstract:
Objective:To investigate the effects of 3D video thoracoscopic surgery combined with 3D CTBA (three-dimensional computed tomography bronchography and angiography) method in clinical education practice of the undergraduates.Methods:The study included in 60 undergraduate clinical interns from our hospital, and they were randomly divided into the experimental group ( n=30) and control group ( n=30). The teaching content was diagnosis and surgical treatment of lung cancer. The experimental group applied 3D video thoracoscopic surgery combined with 3D CTBA teaching method. The interns studied the anatomy of lung and diagnosis of lung cancer based on the 3DCTBA and visited the operation of lung cancer under 3D thoracoscopy, which enhanced their knowledge of anatomical structure of lung. The control group applied traditional thoracoscopic surgery for lung cancer. Upon termination of clinic practice, all interns were tested with theoretical and clinical knowledge of lung cancer. A questionnaire survey was conducted among them to access the teaching effect. SPSS 18.0 was used for t test and chi-square test. Results:The scores of theory test were not significantly different between two groups. The scores of anatomic and operational knowledge of lung in the experimental group were significantly higher compared with the control group ( P<0.05). Questionnaire result showed that new teaching method could promote the interest in learning, motivated the desire for thoracic surgery, and improved the comprehension of clinical knowledge. More students approved the new teaching method. Conclusion:The new method, 3D video thoracoscopic surgery combined with 3D CTBA, has beneficial effect on clinical interns, which contributes to inspire the motivation and interest of learning and deepen clinic knowledge, and is a promising teaching method worthy of further exploration and application.
