目的 评估高仿真肺模型在胸腔镜肺切除术基础技能培训中的应用价值。方法 采用自身对照研究方法。选取2022年5月至2023年9月在人民医院接受胸腔镜技能培训且无胸腔镜手术经验的15名年轻医师作为研究对象,进行为期2周的课程培训,其内容为胸腔探查、血管解剖离断、淋巴结切除、肺楔形切除和标本袋取物5项胸腔镜核心操作。医师在每项技能培训前后均接受评分考核。采用配对样本t检验比较医师在训练前后各项技能的评分差异。结果 与培训前相比,医师培训后5项胸腔镜核心操作技能评分均有提高[(1.0±0)分比(2.9±0.8)分、(1.0±0)分比(3.2±0.9)分、(1.0±0)分比(2.9±0.4)分、(1.4±0.5)分比(3.7±0.9)分、(1.0±0)分比(2.6±0.6)分],其差异均具有统计学意义(均P<0.001)。结论 基于高仿真肺模型的模拟培训能够有效提升年轻医师的胸腔镜手术技能,为安全、高效的胸腔镜技能培训提供了创新性解决方案。
Objective To evaluate the educational value of a high-fidelity lung model in training foundational skills for thoracoscopic lung resection. Methods A self-controlled study design was employed. Fifteen novice surgeons without prior thoracoscopic surgical experience, who participated in a thoracoscopic skills training program at Peking University People's Hospital from May 2022 to September 2023, were enrolled. The surgeons underwent a two-week structured curriculum covering five core thoracoscopic procedures: thoracic exploration, vascular dissection and division, lymphadenectomy, lung wedge resection, and specimen retrieval using an endoscopic retrieval bag. Skill assessments were conducted before and after training for each procedure. Paired-sample t-tests were used to compare skill scores before and after training. Results Following training, participants demonstrated significant improvements in all five core thoracoscopic skills compared to baseline [(1.0 ± 0) vs. (2.9 ± 0.8), (1.0 ± 0) vs. (3.2 ± 0.9), (1.0 ± 0) vs. (2.9 ± 0.4), (1.4 ± 0.5) vs. (3.7 ± 0.9), and (1.0 ± 0) vs. (2.6 ± 0.6), all P<0.001]. Conclusions Simulation-based training utilizing a high-fidelity lung model significantly enhances thoracoscopic surgical skills among novice surgeons. This approach provides an innovative solution for safe and efficient thoracoscopic skills training.
