[Value of thoracoscopy in thoracic trauma--initial experiences].

The aim of this study was to assess the role of thoracoscopy in the evaluation of the cause of persistent intrathoracic bleeding, air leak, or nuclear basal opacification after blunt thoracic trauma. As a result, a decision to proceed to early thoracotomy could be made, or an attempt of thoracoscopic haemostasis, haematoma evacuation, or fistula closure was possible. Twelve patients (9 male, 3 female, mean age 33,7 years) with blunt thoracic trauma underwent video-assisted thoracoscopy under general anaesthesia with double-lumen endotracheal intubation and one-lung ventilation. The indication for operation was made after assessment of chest X-ray and CT findings, pleural ultrasound, and the volume and quality of pleural drainage. Persistent pneumothorax was shown to be due to traumatic rupture of a bulla in two cases and to parenchymal air-leak from a small lung laceration in two cases, all of which were treated endoscopically. In two cases a diaphragmatic rupture was confirmed as the cause of basal shadowing and in one case a major lower lobe laceration was identified as the cause of a persistent haemopneumothorax. In three cases, a fluid collection which could not be evacuated through a pleural drain was shown to be an organised haematoma and was removed endoscopically. Video-assisted thoracoscopy is helpful in the diagnosis and treatment of thoracic trauma, allowing early recognition of injuries that require thoracotomy. It is indicated for persistent (but not life-threatening) intrathoracic bleeding, unresolving pneumothorax, and unclear basal opacification. Therapeutic parenchymal tissue glue application and suturing as well as local resection and haematoma evacuation can be performed with this technique.
