Single-Trocar-Access Thoracoscopy For Fully Optical Controlled Routine Chest Drainage: A Technical Report and Feasibility Study

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.
