The cultivation of scientific research ability of undergraduate medical students is an important direction of medical education reform. At present, there are many problems in medical undergraduate scientific research education, such as heavy curriculum burden, weak scientific research foundation, and one-sided evaluation of training effect. The teaching faculty of Department of Thoracic Surgery of West China Hospital of Sichuan University tried to advance the systematic scientific research training to the early stage of undergraduate course, put forward the “advanced systematic research” teaching model, and explored the practical path to solve the bottleneck problems such as high threshold and poor coherence of scientific research training through hierarchical curriculum design, dynamic management and comprehensive evaluation system. This article will systematically review the exploration process of the advanced scientific research mode of undergraduate medical students at home and abroad, summarize its limitations, and share the practical experience of the above “advanced systematic research” teaching model, so as to provide references and ideas for optimizing the scientific research education of medical undergraduate.
For bilateral multiple pulmonary nodules, two-stage surgery imposes a significant physical and psychological burden on patients due to repeated anesthesia and surgical trauma, making one-stage bilateral surgery a theoretically more ideal treatment strategy. However, conventional one-stage bilateral surgery via the intercostal approach often requires intraoperative repositioning, resulting in greater trauma and prolonged operative time, while the subxiphoid approach faces challenges including insufficient surgical field exposure and severely limited operative space, posing high surgical risks during anatomical lobectomy. This article reports a 54-year-old male patient with bilateral multiple pulmonary nodules, who required a simultaneous left upper lobe wedge resection and a right middle lobectomy. Accordingly, our team successfully performed subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) for one-stage bilateral pulmonary resection. By innovatively incorporating the balance-shaped sternal elevation device for percutaneous suspension technique into subxiphoid uniportal VATS, the operative space was significantly expanded and surgical field exposure was markedly optimized, reducing the risk and difficulty of pulmonary resection via the subxiphoid approach. The patient recovered uneventfully, and short-term follow-up revealed no abnormalities.
