Five cases of contralateral pneumothorax after lung resection

Contralateral pneumothorax is one of severe complications after lung resection. We present our experiences with surgical treatment of 5 cases [case 4 is under the percutaneous cardiopulmonary support (PCPS) assistance] of contralateral pneumothorax after lung resection. All cases were men and not able to stop smoking, the disease caused by lung resection was lung cancer 3 and tuberculosis 2. Operative procedure was lobectomy 4 and pneumonectomy 1. Tracheal intubation was done before radiological confirmation of pneumothorax in 4 cases. Immediately after diagnosis all patients underwent chest drainage. Because the contralateral pneumothorax after lung resection is severe complication, we thought that surgical treatment is necessary. Though the thoracoscopic surgery under the PCPS assistance is also possible, it seems that a small thoracotomy with adjusting ventilation by anesthetist are more favorable. Accurate diagnosis and treatment is the key for success of treatment. The patient who receives lung resection due to lung cancer often has emphysema, and the risk of contralateral pneumothorax after the operation should also be explained.
