[Repair of intrathoracic visceral damage using video-assisted thoracoscopic surgery for blunt chest trauma and rib fixation at the site of mini-thoracotomy].

We treated three patients with intrathoracic visceral damage caused by severely dislocated fractured ribs resulting from blunt trauma by using video-assisted thoracoscopic surgery (VATS) and rib fixation through a mini-thoracotomy. Under general anesthesia and unilateral respiration, the thoracic cavity was inspected with a thoracic video scope through the port inserted through the thoracic drainage opening which was made upon arrival at hospital. As the visceral damage seemed restorable under VATS, a mini-thoracotomy was positioned just above the rib fracture. Two thoracic ports were inserted through the site of rib fracture or through the intercostal space and then VATS was performed using three ports. After the restoration of intrathoracic visceral damage, the fractured rib was fixated using a bioabsorbable poly-L-lactide rib fixation pin or a marlex mesh. Lung injuries were sutured and ligated under VATS in two of our cases and a spur of the fractured rib was shaved in one case. Only severely dislocated ribs were fixated through the mini-thoracotomy in all cases. Air leakage stopped just after this procedure and there were no complications. The rib fixation and bone regeneration were excellent after this procedure. The advantages of this method are the visceral restoration under VATS through a mini-thoracotomy and the ability to perform rib fixation without injuries to the intercostal muscle, artery, vein or nerve. This operative procedure is recommended for intrathoracic visceral damage caused by severely dislocated rib fracture.
