Complications of tube thoracostomy, e.g., organ lesions and malpositioned tubes, are not uncommon. To date, techniques for tube placement have been nonvisualized. The authors believe that a fully visualized penetration of the thoracic wall layers should help to avoid not only perforations and organ lesions but also functionally malpositioned tubes. This article describes a modified endoscopic device, allowing fully visualized and optically controlled access to the pleural cavity for routine chest tube placement. The results of the technical feasibility study for 28 human cadavers showed that it was possible to place the tube as desired. No organ lesions were present. The results suggest that this device and the technique could reduce the risk of complications. The handling of the device is easy and safe. The technique is minimally invasive. The authors' next goal is to prove the results in a clinical study.
胸腔闭式引流术的并发症，如器官损伤和引流管位置不当，并不少见。迄今为止，置管技术一直无法可视化。作者认为，胸壁各层的完全可视化穿刺不仅有助于避免穿孔和器官损伤，还能避免引流管功能位置不当。本文介绍了一种改良的内镜设备，可实现完全可视化和光学控制进入胸膜腔，用于常规胸管置入。对28具人体尸体进行的技术可行性研究结果表明，可以按预期放置引流管。未出现器官损伤。结果表明，该设备和技术可降低并发症风险。该设备操作简便、安全。该技术微创。作者的下一个目标是在临床研究中验证这些结果。
