Fourteen patients underwent surgical resection of bullae between February, 1987 and June, 1990 via median sternotomy. Twelve patients had spontaneous pneumothorax with previous history of pneumothorax on the contralateral side or visible bullae on chest X-ray films. Two patients had bullous emphysema.
The duration of operation and admission, frequency and amount of analgesic administered for pain control, pulmonary function test (FEW FVC, MVV) and the amount of bleedings were compared with six cases of staged unilateral thoracotomy.
The results were as follow
1. All patients were male.
2. Mean follow up period was 13.5 month and no recurrence of pneumothorax are noted after the operation.
3. Mediar sternotomy showed shortened admission days than thoracotomy. (12.42.7, 15.63.1 days)
4. Significantly shortened anesthetic time in median sternotomy than thoracotomy (12121, 18433 minutes)
5. Median sternotomy required less injection of analgesics than thoracotomy. (6.52.7, 13.53.1 amples)
6. Bleeding amout and PFT showed no differences.
7. Complications were prolonged air leakage for more than 7 days (2 patients), transient elevation of SGOT and SGPT(2 patients), and wound infection(1 patient)
