Background: This retrospective study was undertaken to assess the effectiveness of the 8-French (Fr) catheter ($Pleuracan^{(R)}$) for the initial treatment of primary spontaneous pneumothorax. Material and Method: Between July 2004 and July 2006, 59 patients (72 cases) underwent a closed thoracostomy for primary spontaneous pneumothorax. We divided these patients into two groups: group T (large bore (>20 Fr) chest tube group) and group P ($Pleuracan^{(R)}$ group). Result: Initially, the $Pleuracan^{(R)}$ catheters were inserted in 41 cases. There were four catheter malfunctions (9.8%) : three cases had a subsequent closed thoracostomy with a large bore chest tube. Ultimately, there were 34 cases in group T and 38 cases in group P. There were no significant differences in indwelling catheter time ($T:\;2.1{\pm}1.5\;days,\;P:\;2.1{\pm}1.3\;days$), hospital stay ($T:\;6.4{\pm}5.4\;days,\;P:\;5.2{\pm}2.9\;days$) and complications (T: 3%, P: 0%) between the two groups. The percentage of cases that needed intravenous analgesics in group P was 60% (23/38); this was significantly lower than the number for group T (90%, 31/34) (p=0.003). In a subgroup of patients that did not undergo bullectomy(T: 17 cases, P: 19 cases), there were no significant differences in the duration of air leakage ($T:\;0.5{\pm}0.7\;days,\;P:\;0.5{\pm}1.2\;days$) and in the percentage of patients with complete lung re-expansion (T: 94%, P: 84%) between the two groups. Conclusion: Application of the $Pleuracan^{(R)}$ catheter for the initial treatment of primary spontaneous pneumothorax was as effective as the large bore chest tube.

26세 여자환자가 우측 흉통을 주소로 응급실을 방문하였다. 흉부방사선검사에서 우측 기흉을 진단받고 흉관삽입술을 시행하였다. 환자는 6년전부터 레이노드 현상이 있었고 양손에 피부경화증이 있었으며 항 DNA 국소이성화효소 I 항체가 양성으로서 전신성 경화증을 진단받았다. 고해상력 컴퓨터단층촬영에서 양쪽 폐야에 낭종성 병변이 관찰되었고 기흉은 낭종의 파열에 의한 것으로 판단되었다. 전신성 경화증은 폐를 포함한 여러 장기를 침범하는 질환이다. 이 질환에서 기흉과 낭종성 폐병변이 발생하였던 증례들은 1954년 이래로 보고되어 왔는데 모든 증례에서 기흉은 전신성 경화증을 진단받은 뒤에야 발견된 것이었다. 본 증례는 기흉으로 발현한 전신성 경화증의 첫 증례라는 점에서 임상적 의의가 있다고 여겨진다.

Background: The clinical history and physical findings of the patients with spontaneous pneumothorax depend largely on the extent of the collapse of the lung and the presence of pre-existing pulmonary disease. Large primary spontaneous pneumothorax is a possible serious condition and. so more active treatment will be necessary for these patients. The therapeutic guideline for large pneumothorax remains controversial. Therefore, by assessing the clinical results of surgical treatment for large primary pneumothorax, we aim to determine the indicators of treatment. Material and Method: Among 348 patients with primary spontaneous pneumothorax and who underwent surgical treatment from August 2004 through December 2007, 58 patients who responded to treatment for a large primary pneumothorax were included in the current study. We then retrospectively evaluated the operative findings and the surgical results. The patients with a pneumothorax of 80% or more, including those patients with tension pneumothorax, were considered to have a "large pneumothorax". Most of these patients Should be treated with a 12F chest tube. Thoracoscopic wedge resection was considered for treating recurrent pneumothorax, continuous air leakage, controlateral pneumothorax and first episode pneumothorax with visible blebs (> 1cm) seen on the computed tomography. Result: There were 50 men and 8 women with a mean age of 28.2 years (range: $14\sim54$ years). The mean length of hospitalization was 5.3 days (range: $2\sim10$ days). Nine patients underwent chest tube drainage only. Forty-nine patients underwent thoracoscopic wedge resection. The mean follow up time was 27.8 months (range: $10\sim58$ months). The actual site of air leakage could be located in 35 patients (71.4%) and this was correlated with pleural adhesion (p=0.005). The initial air leakage tended to be more correlated with intra-operative air leakage, although this was not statistically significant (p=0.066). The recurrence rate was 11.1 % for the patients with chest tube drainage and 2.0% for the patients with thoracoscopic wedge resection. Conclusion: Large primary pneumothorax requires an early diagnosis and early treatment. Thoracoscopic wedge resection may help to prevent recurrence of large primary pneumothorax.

Acute Complications of Remodelling Plasty of Costochondral Rib Cage For Pectus excavatum Recently, Remodelling Plasty of Costochondral Rib Cage has been introduced as an minimally invasive procedure and expanded its application for pectus excavatum. Outcomes and acute complications were reviewed Material and Method: A retrospective survey of 55 patients who underwent Remodelling Plasty of Costochondral Rib Cage from September, 1999 to February, 2002 was conducted to review complications, postoperative treatments, and outcomes. Result: Age ranged from 1 to 27 years(mean 11.4 $\pm$ 7.1). 35(64%) were less than 15-year old and 20(36%) were more than 15-year old. There were 44(80%) Male patients and 11(20%) female patients. Length of hospital stay was 7.8 $\pm$ 2.1 days for less than 15-Y-old group, 10.6 $\pm$ 6.2 days for more than 15-Y-old group(p ＝ 0.042) One substernal bar was inserted in 52 patients and two substernal bars were inserted in 3 patients. As for stabilizer, one lateral side was fastened in 15 patients and both lateral sides were fastened in 6 patients. In the less than 15-Y-old group, 4 patients needed stabilizer, whereas in the more than 15-Y-old group, 18 patients needed stebilizer(s)(p ＝ 0.000). Including all kinds of complications, 28(51 %)patients had postoperative complications. Of them, only 7 patients were treated for complications(C-tube insertion was done in 7 patients and reoperation for bar refixation or removal was done in 3 patients of them). Conclusion: Most complications after Remodelling Plasty of Costochondral Rib Cage For Pectus Excavatum were trivial without treatment although C-tube drainage was needed in some patients. However bar displacement such as rotation and lateral sliding should be corrected as soon as detected in order not to remove the bar(the worst situation).

Background: To evaluate the risk factor of pneumothorax (PNX) which is the most common complication of CT-guided needle aspiration of the lung, we have examined the frequency of PNX according to the presence of obstructive ventilatory impairment determined by pulmonary function tests. Methods: A comparative study of analysis of forecd expiratory volume and folw-volume curves, and determinations of diffusing capacity taken before procedure were made between each 16 cases with PNX and controls with no PNX. Each of the control group was matched for sex, age, height, and size and depth of lesion with the former. Results: 1) In comparison of vital capacity and parameters derived from forced expiratory volume curve between two groups, VC and FVC were not significantly different, whereas $FEV_1$, $FEV_1$/FVC%, and FEF25-75% showed a significant decrease in the PNX gorup. Also, in the PNX group, all the observed values of parameters analyzed from flow-volune curve were siginificantly reduced in the PNX group compared with those in the control group. 2) The diffusing capacity tended to decrease along with varying individual differences in the PNX group. 3) Patients who had obstructive ventilatory impairment according to the results of pulmonary function tests experienced a twofold increase in the frequency of PNX and a sixfold increase in the frequency of chest tube drainage for treatment of PNX compared with those whose results were normal. Conclusion: These findings suggest that the exact evaluation of obstructive lung disease determined by pulmonary function test be considered assessing a pastient's risk for PNX in the patients who will take the CT-guided needle aspiration of the lung.
