Abstract

BACKGROUND: Video-assisted thoracoscopic surgery(VATS) has been established as a new method for treatment of spontaneous pneumothorax. We compared the clinical results of VATS with those of thoracotomy performed during the recent 5 years. MATERIAL AND METHOD: We analyzed 126 patients whose medical records were available among the 154 patients who underwent operations for spontaneous pneumothorax from 1992 to 1996. The mean age was 27.1 years(15 to 75 years). 87 patients were operated on by VATS(Group A) and the other 39 by thoracotomy(Group B). The mean follow-up period was 14.7 months. RESULT: The operation time was shorter in group A than in group B(90.6+/-38.6minutes: 117.2+/-58.9minutes, p<0.05). The duration of postoperative hospital stay was shorter in group A than in group B(6.7+/-4.2: 9.4+/-3.3 days, p<0.05). The amount of analgesics(nalbuphin HCl, ketoprofen) used postoperatively were 2.4+/-2.8 ampules in group A, which is less than the 6.5+/-5.6 ampules in group B(p<0.05). The number of staples used in group A was smaller(2.7+/-1.3 in group A, 1.76+/-1.1 in group B, p<0.05). The duration of chest tube indwelling(4.3+/-4.0 days in group A, and 5.6+/-3.0 days in group B, NS), the recurrence rate(13.8% in group A, 2.6% in group B, NS), and the duration of air leakage(1.3+/-3.3 days in group A, and 1.0+/-2.5days in group B, NS) were not statistically different between the two groups.
CONCLUSION
The application of VATS for the treatment of spontaneous pneumothorax has brought in better clinical results(shorter operation time, shorter hospital stay, less pain, and better cosmetic merits) than the thoracotomy without increasing any morbidity. However no advantages in recurrence rates and duration of postoperative air leakages are revealed.
