The most common cause of spontaneous pneumothorax is a ruptured bleb, which occurs mostly in young patients and they are usually treated by tube thoracostomy. Recurrence frequently occurs and these patients require some form of surgical intervention. From March 1990 to February 1994, we have experienced 19 cases of recurrent pneumothorax in 16 patients among 347 patients who underwent 423 surgical interventions. The name of first operation after thoracotomy were bullectomy in 4 cases, bullectomy and pleurodesis in 3 cases, bullectomy, pleurodesis in addition to application of tissue sealant in 1 case. Thoracoscopic operations were performed as follows: bullectomy in 2 cases,electroablation plus tissue sealant in 4 cases, electroablation, tissue sealant and pleurodesis in 1 case,and in 4 cases, only tissue sealant was applied. The average age of patients are 21.5 years, and bilaterally operated patients and patients. who received tissue sealant or tissue sealant plus electrocauterization only had higher incidence of recurrence. The patients who needed chest tube insertion longer than 5 days after the first operation were 52.6 %, and 82.3 % recurred within one month of the first operation.

Objective: This study was performed to evaluate the usefulness of early operation in children with traumatic subdural hygroma. Methods: The subjects were nine patients (Glasgow coma scale (GCS) score was below 10 and age was below 10 years old) who developed subdural hygroma after trauma between January 2000 to December 2002. Subduroperitoneal shunt was performed in one group and not performed in the other group. We analyzed the GCS score on admission and at 1 year after operation. Overall clinical results were evaluated retrospectively. Results: Patients who underwent operation exhibited higher GCS scores at 1 year after trauma compared to those in the patients who were treated by conservative therapy(p<0.05). Conclusion: The early operation could be an effective treatment to children with subdural hygroma who showed delayed improvement of consciousness and to patients with hygroma that didn't decrease or was above moderate amount.

From Jan. 1962 to Aug. 1983, one hundred patients with cyanotic heart disease underwent various palliative operations at the department of thoracic and cardiovascular surgery, S.N.U.H. In the period from Jan. 1962 to Dec. 1973, in which the open heart surgery was not routinely performed, sixty-two operations including 2 cases of second shunt operation were performed in sixty patients, and all of them were tetralogy of Fallot except three cases. Various palliative procedures such as Glenn, Brock, Waterston and Blalock-Taussing operation were used in this period with overall mortality rate of 16%. In the period from Jan. 1980 to Aug. 1983, forty patients with cyanotic heart disease were operated and majority of them was complex anomalies. Only Blalock-Taussing operation was used in this period with a mortality rate of 20%. These two groups of patients were compared according to age, diagnosis and results of operations, and it appears that Blalock-Taussing operation is effective palliation for patients with cyanotic heart disease, especially with complex anomaly, with an acceptable mortality.

From Sep. 1978 to Aug. 1986, 44 cases of Fontan operation were performed at Seoul National University Hospital. 1] The diagnoses were TA in 13 [38.6%], UVH in 21 [47.79`], DORV in 3 [6.8%], TGA in 2 [4.5%] and C-ECD with DORY in 1[2.3%]. 2] There were 20 operative deaths [44.5%]. 3] The operative risk factors were early date of operation between 1978 and 1983, young age below 3 years old, direct atriopulmonary anastomosis without roofing, and postoperative high CVP above 25cmH,O. But the relation between operative mortality and various cardiac diseases was absent. 4] survived patients were followed from 1 to 54 months except 3 patients who were lost to follow up. 16 patients were in functional class I and 1 in class II, 2 of the above 17 patients were reoperated due to residual right to left shunt. In remained 4 patients, 3 patients persisted cyanosis after operation and 1 patients died 1 month postoperatively due to pulmonary embolism. 5] As 4 result, the Fontan procedure can be done with a good result for tricuspid atresia and other complex lesions. The operative mortality can be reduced further with a correct anatomical diagnosis preoperatively, rigid operative criteria to pulmonary vascular resistance, direct atriopulmonary anastomosis with roofing, and use of `Venous Assist Device` postoperatively in low cardiac output patients.

Objective : The purpose of this study was to assess the complications, duration of admission, cost effectiveness, radiologic stabilization of the anterior cervical bone fusion in the treatment of cervical disc disease with and without plating. Materials and Methods : Fifty-two surgically treated patients for cervical disc disease were reviewed. Group I consisted of consecutive treated patients with iliac auto-bone graft without instrumentation after anterior cervical discectomy. Group II consisted of consecutive treated patients with iliac autologous-bone graft with CASPER cervical plate fixations. Radiologic fusion was decided when loss of end plate boundary between graft bone and vertebral body and immobile, maintenance of the disc space were evident on simple dynamic plain films. The patients were discharged after the stabilization of cervical motion by films was of tained. These groups were analysed multiple variably with Mann-Whitney U-test. Results : Group I consisted of 18 patients, group II consisted of 34 patients. Mean age was $49.0{\pm}8.1years$, mean duration of admission was $17.27{\pm}10.51days$, mean costs for treatment was $1,970,000{\pm}475,000won$. In group I, mean age was 47.7(34-60) years, 16 patients had undergo on one-level operation, 2-patients had undergo on two-level operation, mean duration of admission was $28.7{\pm}10.4days$, mean costs for treatment was $2,194,473{\pm}561,639won$. The periods of stabilization was $6.6{\pm}3.36weeks$ on radiologic study. Mean periods of out patient follow up was 16.8(6-64) weeks after discharge. Mean period of radiologic follow up was 17.3(4-6) weeks after surgical operation. In group II, mean age was 49.7(37-62) years and 18 patients one-level operation, 14- patients had undergo on two-level operation and 2-patients three-level operation. Mean duration of admission was $11.24{\pm}3.29days$, mean costs for treatment was $1,850,823{\pm}389,372won$. The periods of stabilization was $5.88{\pm}7.07weeks$ on radiologic study. Mean period of out patients follow up was 16.7(4-60) weeks after discharge. Mean period of radiologic follow up was 12.4(3-52) weeks after surgical operation. The duration of admission showed statistical significance in Group II but other items showed no significant difference between two groups. Conclusions : The more economic, early life return and effective method of cervical disc disease in our series were evident in patients who had undergone, iliac bone graft and plate fixations after anterior discectomy.

From January, 1990 to December, 1994, we have operated 10 patients with cardiac rupture. The patients are divided into two groups according to their clinical manifestation ; five patients in each hemorrhage and tamponade group. The patients in both groups could maintain their vital signs with closed thoracostomy and fluid resuscitation. The effect of pericardiocentesis was especially dramatic in three patients of tamponade group. The average time from injury to admission was 101 minutes and that of the patients who came our hospital via one or two other hospitals was 170 minutes comparing 31 minutes of those who came directly. The average time from admission to operation was 211 minutes. Considering 98 minutes for the diagnosis and preoperative management and another 30 minutes for the preparation for operation, operations were delayed by 83 minutes to get permission. We conclude that this delaying time for transport and operation of heart-ruptured patients should be shortened in order to manage them more effectively.

Purpose: Blunt small bowel injury (SBI) is frequently combined other organ injury. So, clinical outcome and characteristics of SBI are influenced by other combined injuries. Thus, we analyzed isolated SBI patients and studied clinical outcome and characteristics. Methods: Between 2005 and 2010, 36 consecutive patients undergoing laparotomy due to isolated SBI were identified in a retrospectively collected. Database. Clinical outcome and characteristics were analyzed. Results: Laparotomy was performed in 36 patients. Primary repair was performed 17 patients. Segmental resection of small bowel was performed 19 patients. Median time gap from trauma to operation was 9 hours. In 24 hours from trauma, operation was performed 31 patients. Post operative death was 5 patients. Mean hospital stay was 18 days and median hospital stay was 12 days. There were significant differences between operation type and minor complication and hospital stay. And there were significant differences between time gap in 24 hours and minor complication. But, there were no significant between time gap and mortality. Conclusion: Although this study had many limitations, some valuable information was produced. When operation above 24 hours was delayed in SBI, minor complications were significantly increased. Segmental resection of small bowel in SBI were significantly increased minor complications and hospital stay. So, preventive measures for surgical site infection was important to reduce wound complication and hospital stay. Further continuous study and multi-center study were should be performed to improve clinical outcome in SBI.

We reviewed our experiences on 33 patients who underwent a bidirectional cavopulmonary shunt[BCPS from February 1992 to July 1994. There were 19 male an 14 female patients, and their weight ranged from 4.4 to 13.3 Kg[mean weight 8.4 $\pm$2.9 Kg . The age ranged from 2 to 55 months [mean age 16.7 $\pm$15.5 months . Their diagnosis included single ventricle group in 16, unbalanced ventricles in 8 whose associated anomalies were double outlet right ventricle, transposition of great arteries and total anomalous pulmonary venous return, tricuspid atresia in 7, hypoplastic left heart syndrome in 1 who underwent a Norwood procedure and double outlet right ventricle with pulmonic stenosis and tricuspid stenosis in 1 who underwent biventricular repair. Among them 10 patients had received other palliative operation before [Norwood procedure 1, pulmonary artery banding 3, modified Blalock-Taussig shunt 6 . The BCPS operations were performed under the cardiopulmonary bypass. 16 patients underwent unilateral BCPS and 17 patients who had bilateral SVC underwent bilateral BCPS. Three patients whose associated anomalies were interruption of IVC underwent total cavopulmonary shunt. There were 5 operative deaths [mortality rate 15.1 % and 2 late deaths. The risk factor for the operation was high mean pulmonary artery pressure [p value<0.05 . The survivors showed good postoperative course and their postoperative oxygen saturation was increased significantly compared to that of preoperative status[p value<0.05 .Conclusively, BCPS operation is effective and safe palliative procedure for the many cyanotic complex congenital anomalies with decreased pulmonary blood flow especialy for the patients who have the high risk factors for Fontan operations.

To evaluate the long-term prognosis of biliary atresia after Kasai operation, a total of 14 patients (of the 41 patients operated upon from 1982 to 1997), who had been followed up for more than 10 years, were included in this retrospective study. Eleven out of 14 patients survived with their native livers, and their data analyzed for age at operation, clearing time of jaundice, histological outcome, postoperative complications, effectiveness after the application of an intussusception anti-reflex valve, and quality of life. Average age at surgery was 62.8 days. Serum bilirubin was normalized within three months in all patients. Six among the eleven long-term survivors had ascending cholangitis as one of the postoperative complications. The application of an intussusception anti-reflux valve did not show any statistical significance in long-term survival. Most of long-term survivors appeared to enjoy good quality of life. Kasai operation might not be the definitive treatment for biliary atresia; however, Kasai operation made it possible to achieve long-term survival for patients with biliary atresia when the patients were detected and treated as early as possible.

Recently, the arterial switch operation has received more interest and increased application for many patients with TGA [Transposition of the Great Arteries]. Not all patients, however, are suitable candidates for this approach, and its success will be measured against the Senning procedure. From June 1982 through June 1989, 48 consecutive patients underwent correction of TGA by a modification of the Senning procedure in our hospital. 34 were males and 14 females, with ages ranging from 3 months to 99 months [mean age 14 months]. The patients were divided into two groups, group I [TGA with intact ventricular septum or without significant pulmonary hypertension] and group II [TGA with significant pulmonary hypertension]. The hospital mortality was 9.5 % in group I and 55.6 % in group lI. 31 patients were discharged from the hospital after a Senning operation and have been followed a mean of 31.2 months. There were 5 late deaths, 3 in group I and 2 in group II. All patients were followed up with EKG, echocardiogram, and in several cases, Holter monitor and cardiac catheterization and angiography were also performed. There have been arrhythmias in 7, superior vena caval obstruction in 5, pulmonary venous obstruction in 2 and tricuspid insufficiency and/or right ventricular dysfunction in 16 patients. The Senning operation for Simple TGA can be performed with a low operative mortality and morbidity, but tricuspid insufficiency and/or depressed right ventricular function can be a problem with prolonged follow up.
