Fewer patients undergo pediatric lung transplantation (PLT) than adult lung transplantation. Size mismatch is the key factor that limits the availability of potential donors. Every candidate for PLT is in a different scenario in terms of age, height and weight, size of structures, indications for PLT, the concomitant presence of a cardiac anomaly, and other individual-specific factors; thus, a thorough understanding of pediatric patients' medical problems is essential. Living-donor lobar lung transplantation (LDLLT) has only been performed once in Korea to date. However, since each step in the LDLLT is a well-established procedure, including intrapericardial lobectomy, lung procurement, and lobar lung transplantation, qualified surgeons and lung transplantation teams are competent to perform LDLLT in clinically necessary situations.

Background: We evaluated the feasibility and the efficacy of Video-Assisted Thoracic Surgery (VATS) lobectomy for treating patients with non-small cell lung cancer (NSCLC) and we compared the outcomes of VATS lobectomy with those of open lobectomy. Material and Method: From 2003 to March 2008, 133 NSCLC patients underwent VATS lobectomy. The patients were selected on the basis of having clinical stage I disease on the chest CT and PET scan. The outcomes of 202 patients who underwent open lobectomy (OL group) for clinical stage I NSCLC were evaluated to compare their results with those of the patients who underwent VATS lobectomy (the VL group). Result: The number of females and the number of patients with adenocarcinoma and stage IA disease were greater in VL group (p<0.05). There was no operative mortality or major complications in the VL group. Conversion to thoracotomy was needed in 8 cases (6%), which was mostly due to bleeding. The chest tube indwelling time and the length of the postoperative hospital stay were significantly shorter in the VL group (p<0.001). The number of dissected lymph nodes and the size of tumor were significantly smaller in the VL group (p<0.001). For the pathologic stage I patients, there was no significant difference in the three-year survival rates between the two groups (p=0.15). Conclusion: VATS lobectomy is a safe procedure with low operative mortality and morbidity. VATS lobectomy is feasible for early stage NSCLC and it provides outcomes that are comparable to those for open lobectomy. Further long-term data are needed.

MMinimally invasive surgery (MIS) for early stage lung cancer has been an important treatment modality. However, the ergonomic discomfort and counterintuitive instruments hindered the application of video-assisted thoracic surgery (VATS) to more advanced procedures. To improve the compliance with MIS, robotic surgery was adopted. This advance aimed to alleviate the shortcomings of VATS by maximizing the comfort of the surgeon while providing instruments that enabled technically demanding operations and three-dimensional views with increased freedom for intrathoracic movement owing to EndoWrist$^{(R)}$. In this session, we introduced the clinical applications and its results of robot-assisted thoracic surgery in the field of lung cancer surgery. In conclusion, robot-assisted pulmonary resection with lymph node dissection for lung cancer is safe as well as feasible, and it results in a satisfying postoperative outcome. Robot-assisted surgery may provide a good alternative to conventional open or thoracoscopic surgery for lung cancer, provided that the cost effectiveness and long-term prognosis are confirmed.

Background: Assessments of air leaks are usually performed subjectively, precluding the use of air leaks as an evaluation factor. We aimed to identify objective parameters as predictive factors for prolonged air leak (PAL) and air leak cessation (ALC) from air flow data produced by a digital drainage system. Methods: Flow data records of 352 patients who underwent lung lobectomy were reviewed, and flow data at designated intervals (1, 2, and 3 hours postoperatively [POH] and 3 times a day thereafter [06:00, 13:00, 19:00]) were extracted. ALC was defined by flow less than 20 mL/min over 12 hours, and PAL was defined as ALC after 5 days. Cumulative incidence curves were obtained using Kaplan-Meier estimates of time to ALC. Cox regression analysis was performed to determine the effects of variables on the rate of ALC. Results: The incidence of PAL was 18.2% (64/352). Receiver operating characteristic curve analysis showed cut-off values of 180 mL/min for the flow at 3 POH and 73.3 mL/min for the flow on postoperative day 1; the sensitivity and specificity of these values were 88.9% and 82.5%, respectively. The rates of ALC by Kaplan-Meier analysis were 56.8% at 48 POH and 65.6% at 72 POH. Multivariate Cox regression analysis revealed that the flow at 3 POH (≤80 mL/min), operation time (≤220 minutes), and right middle lobectomy independently predicted ALC. Conclusion: Air flow measured by a digital drainage system is a useful predictor of PAL and ALC and may help optimize the hospital course.

We experienced 29 cases of patients with a chief complaint of hemoptysis who were performed pulmonary resection at the Department of Thoracic and Cardiovascular Surgery, Pusan Medical Center Hospital for 3 years from May 1990 to April 1993. The mean age of hemoptysis patients was 34.7 year old, and hemoptysis was most prevalent in third and fourth decades. The underlying lung diseases of hemoptysis patients were tuberculosis in 12[41.4% , bronchiectasis in 9[31.0% , lung cancer in 4[13.8% , aspergyllosis in 3[10.3% and pneumonia in 1[3.5% . Modes of hemoptysis were blood tinged in 7[24.1% , massive in 22[75.9% . Operation times were elective in 7[24.1% of all blood tinged hemoptysis, delayed in 20[69.0% , emergency in 2[6.9% out of massive hemoptysis. The cases of the definite bleeding focus found by bronchoscopy were 19 cases[65.5% . The operative procedures of hemoptysis were single lobectomy in 14[48.3% , pneumonectomy in 6[20.7% , lobectomy with segmentectomy in 5[17.2% , bilobectomy in 3[10.3% and segmentectomy in 1[3.5% . The postoperative results of hemoptysis were complete recovery in 27[93.0% , rehemoptysis in 1[3.5% which was treated by anti-Tbc medication completely, and hospital death in 1[3.5% which was brain metastasis of lung cancer. It was concluded that definitive diagnosis, preoperative control of hemoptysis and operation were important in the management of hemoptysis patients.

A 39-year-old male was admitted to Dept. of Thoracic Cardiovasc. Surgery, Korea University Hospital with the chief complaints of progressively enlarged mass on right upper lung which revealed on routine chest P-A since 4 Years ago. Chest PA and tomography revealed well circumscribed huge mass of 7cm. in diameter without invasion on bronchus. so, right upper lobectomy was performed under impression of lung cancer. Postoperative pathologic examination revealed pulmonary blastoma. Pulmonary blastoma is accepted as a distinctive neoplasm recently. One case of typical pulmonary blastoma is reported, and the previous literature is reviewed. There are no specific clinical or radiologic feature of pulmonary blastoma. The presentation is can be that of any other pulmonary tumor although a peripheral situation is usual and a large size is often attained before detection. Pulmonary blastoma is a mixed tumor with malignant epithelial and connective tissue components with a distinctive resemblance to fetal lung. The treatment of choice is surgical excision but the overall prognosis is poor. There is no evidence of recurrence or metastasis on follow-up study during 6 months period after right upper lobectomy.

Sleeve resection is safe, effective, and appropriate treatment for a wide range of endo-bronchial lesions including neoplasms of low grade malignant potential and selected cases of bronchogenic carcinoma. Five cases of bronchoplastic procedures were performed for primary bronchogenic carcinoma patients at Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital from Aug. 1983 to Oct. 1987. Of the 5 patients, four were male and one patient was female and ages ranged from 51 years to 66 years old. Histopathologically, 4 cases were squamous cell carcinoma and one case small cell carcinoma. Operative procedures of the 5 patients were as follows: Right upper sleeve lobectomy, 1 case; Left upper sleeve lobectomy, 1 case; left lower sleeve lobectomy, 1 case; Left lower lobe and lingular segment sleeve resection, 2 cases. The early and late postoperative complications of the above operations were pneumonia, atelectasis, bronchopleural fistula, empyema, brain metastasis, and local recurrence of primary tumor.

We describe unusual manifestations of congenital cystic adenomatoid malformation (C.C.A.M.) of the lung, such as movable fungal ball-like intracystic blood clots and hemoptysis, which were detected in previously healthy 23 years-old woman. We identified blood clots only after left upper lobectomy and could not distinguish from fungal ball with radiographic methods. CCAM of the lung, rare and lethal form of congenital pulmonary cystic disease, was initially introduced by Ch, in and Tang in 1949. The histogenesis of this lesion is characterized by polypoid glandular tissue proliferation and overgrowth of mesenchymal elements due to cessation of bronchiolar maturation which occurred in after 16weeks intrauterine period. In 80-95% of reported cases, the lesion was confined to a single lobe and there was no lobe and right and left lung predilection The clinical presentation may be widely variable, ranging from intrauterine fetal death to late discovery in childhood with recurrent pulmonary infection. But there,s no reports which were misdiagnosed with intracystic fungal ball. The treatment choice is lobectomy of affected lobe. There,s a few case reports with rhabdomyosarcoma, bronchiolar cell carcinoma and myxosarcoma arising in CCAM patients. Therefore, early resection is recommended even if asymtomatic cases. We experienced a rare case of CCAM of the lung in 23 years old female, and there were intracystic fungal ball-like movable blood clots in lower portion of left lung. After left upper lobectomy was performed, now she is discharged and followed up without any complications.

Multiple primary lung cancer is a rare disease entity and its clinical characteristics, treatment, and prognosis are poorly described. But the multiple primary lung cancer have a more favorable prognosis than locally recurrent or metastastic disease. Therefore, appropriate identification of multiple primary lung cancer will be very important. We have experienced a case of stage I multiple primary lung cancer in a 76-year-old male with two large mass in the right lower lobe without metastasis in the mediastinal lymph nodes with right mid and lower lobectomy. The microscopic pictures revealed adenocarcinoma in the one & small cell carcinoma in another. The post-operative courses were in uneventful for 4 months & but he was treated with chemotherapies, 2 times for complete remission of small cell carcinoma to now after discharge.

Video-assisted thoracic surgery (VATS) is a minimally invasive technique that has many advantages in postoperative pain and recovery time. Because of its advantages, VATS is one of the surgical techniques widely used in patients with lung cancer. Most surgeons perform VATS for lung cancer with three or more incisions. As the technique of VATS has evolved, single-port VATS for lung cancer has been attempted and its advantages have been reported. We describe our experiences of VATS for lung cancer with a single incision in this report.
