Background: Although treatment of spontaneous pneumothorax by video-assisted thoracic surgery(VATS) has generally shown better clinical results than conventional thoracotomy, treatment of spontaneous pneumothorax by midaxillary thoracotomy(MAXT) has also shown good clinical results. The author studied to compare the clinical results of MAXT group I and VATS group II. Material and Method : Group I included 30 midaxillary thoracotomy among 83 operative cases of spontaneous pneumothorax from Jan. 1992 to Dec. 1993. Group II included 30 VATS among 101 operative cases of pneumothorax from Jan. 1994 to Aug. 1995. The author selected the 30 patients, age 18 to 25 years, with recurrent spontaneous pneumothorax in each group. The author analyzed the operative indication, gender, operating time, amounts of the used staplers, tube drainage, total amounts of analgesics used during postoperative 24hr, tube stay time, postoperative complications and mortality. Result: The follow-up periods of both procedures were from 6 to 43 months. The operating time from start of skin incision to end of skin closure was 84.79${\pm}$21.70(from 40 to 150) minutes in MAXT group I and 108.8${\pm}$42.02(from 58 to 120) minutes in VATS group II(P<0.001). The numbers of the used staples useo was 1.31${\pm}$0.6(from 0 to 3) in group I and 3.41${\pm}$2.37(from 0 to 11) in group II. The amounts of postoperative 24hour tube drainage were 220.76${\pm}$106.73(from 65 to 400) ml in group I and 260.63${\pm}$233.18(from 70 to 320) in group II(P>0.05). The amounts of postoperative 24 hourly used analgesics(Tarasyn ) was 1.38${\pm}$1.32(from 0 to 5) amples in group I and 0.72${\pm}$1.02(from 0 to 4) amples in group II (P<0.05). The postoperative tube stay is 5.45${\pm}$30.9 (from 3 to 7) days in group I and 4.75${\pm}$3.1(9 from 2 to 14) days in group II(P>0.05). The number of complications after operations was 2 cases of prolonged air leakage in group I, and in group II. (P is not significant). The number of recurrence after the operation was one in group I and also one in group II(P is not significant). In conclusion, there were no statistical differences in the postoperative 24 hour chest tube drainage, days of postoperative tube stay, postoperative complications and recurrence in the analysis between group I and group II. Conclusion: The author found that group II of VATS between 18 years and 25 years of age in recurrent spontaneous pneumothorax, statistically, requires longer operative time, more number of autosuture staples and less postoperative analgesic dosage than the midaxillary thoracotomy group I.

Since thoracoscopy was originally described by Jacobaeus in 1922, video-assisted thoracic surgery has been used to treat many thoracic diseases. From June 1994 to July 1995, 35 patients with spontaneous pneumothorax'underwent video-assisted thoracic sugery as experimental group, and same number of patien:s with blob resection through mid-axillary thoracotomy as co trol group in our hospital.'The authors compared the clinical results between each group. 1. The sex distributions were 28 males, 7 females in experimental group and 30 males, 5 females in control group. The mean age of experimental group was 28.5 $\pm$ 12.6 years of age and that of control group was 2).9 $\pm$ 6.3 years of age. 2. The operative times were 98.8$\pm$ )9.3 minutes in experimental group and 103.6$\pm$ )2.6 minutes in control group. ). The duration of chest tube indwelling at postoperative period was 2.60 $\pm$ 0.98 days in experimental group, 4.80 $\pm$ 2.08 days in control group (P< 0.01). The periods of postoperative hospitalization were 17 $\pm$ 1.22 days in experimental group and 6.69 $\pm$2.52 days in control group. The durations of post-oper- ative chest tube indwelling and hospital stay in experimental group were shorter than in control group (P< 0.01 respectively). 4. The injection of analgesics at postoperative period was less in experimental group than control group. At the operative day and postoperative 1 st and 2nd day, the number of injections were respectively 1. 57$\pm$0.74, 1.97 $\pm$0.70 and 1.00$\pm$0.68 times/person in experimental group, 2.23 $\pm$0.60, 2.60 $\pm$0.67 and 2. 17$\pm$0.76 times/person in control group(P<0.01 respectively). The mean duration and dose of postoperative analgesic injection were 2.48$\pm$ 1.01 days/person and 4.88 $\pm$3.70 ampules/person in experimetal group, 3.70$\pm$ 1.40 days/person and 8.94 $\pm$4.21 ampules/person respectively (P< 0.01, p<0. 01).

A total of 20 patients underwent bullectomy in the spontaneous pneumothorax between October 1993 and August 1994. The patients were divided into two groups: Control group; the patients who received with mid-axillary approach[n=10 , Experimental group; the patients who received with video-assisted thoracic surgery [n = 10 . The results were as follows; 1. The total sex distribution was male predominence [M :F=6:1 . Mean age of control group was 31.6$\pm$ 10.1 age and experimental group was 24.3$\pm$ 5.5 age. 2. The operative times were 117.0 $\pm$ 32.6min in control group and 102.5$\pm$ 38.4min in experimental group [not significant . 3. The indwelling period of postoperative chest tube and hospital stay were 4.5$\pm$ 2.6 days and 8.3 $\pm$ 1.8 days in control group, $1.5\pm$ 0.5 days and 3.1 $\pm$ 0.3 days in experimental group[p=0.0018, < 0.0001 . 4. In control group, injection times of pain-killer were 1.7$\pm$ 0.7 times/day at operative day and 0.4$\pm$ 0.6times/day at postoperative 1 day. In experimental group, there were 0.3$\pm$ 0.7times/day at operative day and 0.1 $\pm$ 0.3times/day at postoperative 1 day[p=O.O002 at operative day, not significant at postoperative 1 day .
