연구배경: 비소세포성 폐암 수술시 sleeve 폐엽절제술은 가능한한 폐실질을 보존하기 위한 수술방법으로, 폐기능이 감소되어 있는 환자에서도 폐절제술을 시행할 수 있다. 그러나 sleeve 폐엽절제술 후 폐기능이 기대했던 것 만큼 보존되는지에 대한 국내의 보고가 없어 sleeve 폐엽절제술 후 폐기능의 보존정도에 대해 연구 하였다. 방법: 1995년부터 1998년까지 삼성서울병원에서 sleeve 폐엽절제술을 받은 폐암 환자중 수술 후 3개월 이후에 기관지내시경 검사, 폐기능검사를 시행받은 15명의 환자를 대상으로 수술 전 예상 $FEV_1$과 수술 후 실제 $FEV_1$과의 차이를 비교 분석하였다. 수술 전 예상 $FEV_1$은 수술 전 $FEV_1$에 수술 후 잔류폐엽의 폐관류 정도(%)를 곱한 값으로 계산하였다. 결과: 15명 환자의 연령의 중앙값은 58세(44세-70세)였고, 남녀비는 14:1이었다. 모두 비소세포성폐암이었으며 상피세포암이 13명, 선암이 2 명이었다. 우측 상엽 sleeve 폐업절제술이 8명, 우측 중엽과 하엽을 동시에 제거하는 양엽 sleeve 폐엽절제술이 3명, 좌측 상엽 sleeve 폐엽절제술이 4명이었다. 환자들의 수술 전 평균 $FEV_1$은 $2417{\pm}694mL$ 였고, sleeve 폐엽절제술을 받을 경우 예상 $FEV_1$용 $2180{\pm}570mL$ 였다. Sleeve 폐엽절제술 후 실제 $FEV_1$은 $2293{\pm}499mL$로 수술 전 예상 $FEV_1$과 의미있는 상관관계을 보여 (r = 0.67, P<0.05), 전폐절제술을 시행했을 때보다 폐기능을 보존할 수 있었다. 각 환자의 수술 전 $FEV_1$과 수술 후 실제 $FEV_1$을 비교해 보았을 때 수술 전 $FEV_1$이 적었던 (<2L) 4명의 환자에서는 오히려 수술 전보다 수술 후 $FEV_1$이 증가하였다. 결론: 폐암의 수술에 있어 sleeve 폐업절제술은 예상했던 것 만큼 폐기능이 잘 보존되었고, 특히 수술 전 폐기능이 저하되어 있는 환자에서 유용한 수술수기로 이용될 수 있을 것으로 생각 되었다.

Video-assisted thoracic surgery (VATS) has been recommended as more optimal surgical technique than traditional thoracotomy for lobectomy in lung cancer, but it is not well defined. Here, we compared VATS and traditional thoracotomy based on clinical data. From November 2008 to November 2010, 180 patients underwent lobectomy for non-small-cell lung cancer (NSCL) identified by computerized tomography. Of them, 83 cases were performed with VATS and 97 by thoracotomy. Clinical parameters, consisting of blood loss, operating time, number of lymph node dissection, days of pleural cavity drainage, and length of stay were recorded and evaluated with t test. No significant difference was observed between the VATS and thoracotomy groups in the average intraoperative blood loss, number of lymph node dissections, and days of pleural cavity drainage. While the average operating time in the VATS group was significantly longer than that in thoracotomy group, recurrence was only present in one case, as opposed to 7 cases in the thoracotomy group In conclusion, similar therapeutic effects were demonstrated in VATS and thoracotomy for NSCL. However, VATS lobectomy was associated with fewer complications, recurrence and shorter length of stay.

Vertical axillary muscle sparing thoracotomy is newly appeared and excellent alternative method of standard posterolateral thoracotomy.It has many advantages compared to standard posterolateral thoracotomy , less postoperative pain, well preserved thoracic muscle strength, full range of motion of the shoulder girdle and attractive cosmetic results. We performed vertical axillary muscle sparing thoracotomy in 36 patients from November 1993 to July 1994. The ages of the patients ranged from 6 months to 71 years[mean 45.1 years , and the patients consisted of 20 males and 16 females.The preoperative diagnosis were as follows : lung cancer in 17 patients, tbc destroyed lung in 7, bronchiectasis in 3, bullous emphysema in 3 and the others are mediastinal tumor, bronchogenic cyst, lung abscess, empyema, esophageal diverticulum, and CCAM [congenital cystic adenomatoid malformation . The operative procedures were as follows : lobectomy and bilobectomy in 16 patients, segmentectomy in 4, wedge resection in 3, penumonectomy in 7, and the others were open biopsy, lobectomy with diaphragm excision, sleeve right upper lobectomy, decortication, mediastinal mass excision, and esophageal diverticulectomy. We had 6 complications : postoperative bleeding in 2 cases, operative wound infection, arrrhythmia[atrial fibrillation , Horner`s syndrome, hoarseness. The subcutaneous seroma occurred in 4 cases but did not require drainage and relieved within 4 weeks spontaneously. We concluded that vertical axillary muscle sparing thoracotomy could be done in most of all thoracic surgery with safety. Comparing to standard posterolateral thoracotomy vertical axillary muscle sparing thoracotomy has many advantages such as less postoperative pain, well preserved muscle strengths and good cosmetic results.

Background: In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. Methods: A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2016 were retrospectively reviewed, including 47 in the triple-port group and 26 in the single-port group. Statistical analysis was performed after propensity score matching. Patients were matched on a 1-to-1 basis. Results: Operative time and intraoperative blood loss in the triple-port group and the single-port group were similar ($189.4{\pm}50.8minutes$ vs. $205.4{\pm}50.6minutes$, p=0.259; $286.5{\pm}531.0mL$ vs. $314.6{\pm}513.1mL$, p=0.813). There were no cases of morbidity or mortality. No significant differences in complications or the total number of dissected lymph nodes were found between the 2 groups. In the single-port group, more mediastinal lymph nodes were dissected than in the triple-port group ($1.7{\pm}0.6$ vs. $1.2{\pm}0.5$, p=0.011). Both groups had 1 patient with bronchopleural fistula. Chest tube duration and postoperative hospital stay were shorter in the single-port group than in the triple-port group ($8.7{\pm}5.1days$ vs. $6.2{\pm}6.6days$, p=0.130; $11.7{\pm}6.1days$ vs. $9.5{\pm}6.4days$, p=0.226). However, the differences were not statistically significant. In the single-port group, the rate of conversion to multi-port VATS lobectomy was 11.5% (3 of 26). The rates of conversion to open thoracotomy in the triple-port and single-port groups were 7.7% and 3.8%, respectively (p=1.000). Conclusion: In comparison with the triple-port group, single-port VATS lobectomy showed similar results in safety and efficacy, indicating that single-port VATS lobectomy is a feasible and safe option for lung cancer patients.

Pulmonary function studies today are generally accepted as an integral part of the evaluation of poor-risk patients who are to have pulmonary surgery. The effect of various pulmonary surgery on lung function was investigated in 54 patients in whom comprehensive lung function test were performed before and between 2 months and 14 months after operation at the Department of Thoracic Surgery, Seoul National University Hospital. According to the result of analysis, the effect of pulmonary resection on forced flow rate was keeping with the change of lung volume, and the preoperative level of ventilatory function plays a major role in determining postoperative loss of functioning lung. Although all measures of expiratory flow [FVC, FEV1, FEFO.2-1.2, MEF50, FEF25-75] have the same percentage of reproducibility, but FEV1 shows most sensitive, reliable linear correlation with the functioning pulmonary tissue loss than other parameters. The linear regression lines derived from the correlation between preoperative [X] and postoperative [Y] FEV1 on various surgical procedures were as follows: 1. Y = 0.57X 0.03. in pneumonectomy group of lung cancer[r=0.84]. 2. Y = 0.56X + 0.33. in lobectomy group of lung cancer[r=0.79]. 3. Y = 0.69X + 0.25. in lobectomy group of pulmonary infection[r=0.91].

Mediastinal lymph node involvement [N2 disease] is generally accepted as an important factor influencing the outcome of patients with lung cancer.The long-term survival rates of completely resected patients with N2 disease are frequently reported from 15% to 30%.To improve the management and the outcome of patients with resectable N2 disease, we analyzed the survival rates and the prognostic factors for resected N2 lung cancer. Between August 1989 and September 1993, we experienced 27 patients with N2 disease of 115 surgically treated lung cancer at the Department of Thoracic and Cardiovascular Surgery, Asan Medical Center, Ulsan University Medical School. Of these 27 N2 disease 4 had only an exploratory thoracotomy, and 23 underwent pulmonary resection by pneumonectomy[15], bilobectomy[3], lobectomy[4] and sleeve lobectomy[1].All of resected 23 patients received postoperative adjuvant chemotherapy[3], radiotherapy[2] or combined chemo-radiotherapy[18].Complete follow-up was obtained in 23 patients and median survival was 22 months and overall 1-year and 2-year survival rates by Kaplan-Meir method were 65 % and 45 %, respectively. Survival differences according to histology, tumor location, number of positive nodal station and operative method were not significant, statistically. Conclusively, we think that in resectable N2 lung cancer, complete tumor resection and mediastinal lymph node dissection, and postoperative adjuvant therapy should be done to improve the survival.

Background: Surgical treatment of stage I non-small cell lung cancer (NSCLC) can be performed either by thoracotomy or by employing video-assisted thoracic surgery (VATS). The aim of this study was to evaluate the feasibility of VATS lobectomy for pathologic stage I NSCLC. Material and Methods: Between December 2003 and December 2007, 529 patients with pathologic stage I NSCLC underwent lobectomies (373 thoracotomy, 156 VATS). Patients in both groups were selected after being matched by age, gender and pathologic stage using propensity score method, to create two comparable groups: thoracotomy and VATS groups, and the overall survival, recurrence-free survival, complication and length of hospitalization were compared between these two groups. Results: After the patients were matched by age, gender and pathologic stage, 272 patients remained eligible for analysis, 136 in each group (mean age of 59.5 years; 70 men, 66 women; 80 stage IA, 56 stage IB). There was no statistical difference in other preoperative clinical characteristics between the two groups. No hospital mortality was observed in both groups. Overall 3-year survival rate was 97.4% in thoracotomy group and 96.6% in VATS groups (p=0.76). During the follow-up, 20 patients (14.7%) developed recurrence in thoracotomy group, including loco-regional recurrence in 7, distant metastasis in 13. In VATS group, 13 patients (9.6%) developed recurrence, including loco-regional recurrence in 4, distant metastasis in 9. Three-year recurrence-free survival rate was 81.8% in thoracotomy group and 85.3% in VATS groups (p=0.43). There was no significant difference in postoperative complications between thoracotomy and VATS groups (30 cases in 22 patients vs. 19 cases in 17 patients, p=0.65, odds ratio=1.19). The mean hospital stay of VATS group was 2 days shorter than that of thoracotomy group ($8.8{\pm}6.5$ days vs. $6.3{\pm}3.3$ days, p<0.05). Conclusion: VATS lobectomy for pathologic stage I lung cancer is a feasible operation with shorter hospitalization, while surgical outcome is comparable to thoracotomy lobectomy.

Pseudocysts of lung by blunt chest trauma are rare lesion with 1 to 2 % incidence. The symptoms are nonspecific and misled or confused with lung abscess or congenital cystic disease of lung occasionally. Diagnosis is not difficult by radiographic findings and history of blunt chest trauma. There courses are benign and spontaneously absorbed and require no specific treatment mostly. Recently, we had the one case of 8 year-old female with traumatic lung cyst and its cavities filled the entire right lower lobe. The destruction of lung was severe, so, right lower lobectomy was done and recovered, discharged without event.

We experienced 48 operations in 46 surgical patients of bronchiectasis admitted to the Department of Thoracic and Cardiovascular Surgery of Jeonbug National University Hospital from January, 1975 to August, 1982. Among 46 patients, 27 patients [59%] was age group between 21 to 30 years. Common symptoms were cough with sputum, hemoptysis, dyspnea, fever and chilliness, and chest pain. The duration of the symptoms was variable between below one year and above 10 years. The most frequent associated disease, probably the cause of the bronchiectasis, was secondary bacterial infection after viral infection. The left lower lobe and lingular segment was involved most frequently, and the most frequent pathologic type was mixed type [40%]. Single lobectomy, and combined lobectomy and segmentectomy were performed in 77% of the patients. Bilateral resection was performed in three patients with good result. In those patients, the isolated pulmonary function test on each side of the lung performed 2 month later primary lung resection could make them be prevented from pulmonary insufficiency after secondary lung resection. The results were good except two patients who developed pulmonary insufficiency and chronic empyema with bronchopleural fistula.
