Background: Video-assisted thoracic surgery (VATS) lobectomy has been performed with increasing frequency over the last decade. However, there is still controversy as to its indications, safety, and feasibility. Especially regarding lung cancer surgery, it is not certain whether it can reduce local recurrences and improve overall survival. Materials and Methods: We retrospectively reviewed 1,067 cases of VATS lobectomy performed between 2003 and 2009, including the indications, postoperative morbidity, mortality, recurrence, and survival rate. Results: One thousand and sixty seven patients underwent VATS lobectomy for the following indications: non-small cell lung cancer (NSCLC) (n=832), carcinoid tumors (n=12), metastatic lung cancer (n=48), and benign or other diseases (n=175). There were 63 cases (5.9%) of conversion to open thoracotomy during VATS lobectomy. One hundred thirty one (15.7%) of the 832 NSCLC patients experienced pathologic upstaging postoperatively. The hospital mortality rate was 0.84% (9 patients), and all of them died of acute respiratory distress syndrome. One hundred forty-nine patients (14.0%) experienced postoperative complications. The median follow-up was 22.9 months for patients with NSCLC. During follow-up, 120 patients had a recurrence and 55 patients died. For patients with pathologic stage I, the overall survival rate and disease-free survival rate at 3 years was $92.2{\pm}1.5%$ and $86.2{\pm}1.9%$, respectively. For patients with pathologic stage II disease, the overall survival rate and disease-free survival rate at 3 years was $79.2{\pm}6.5%$ and $61.9{\pm}6.6%$, respectively. Conclusion: Our results suggest that VATS lobectomy is a technically feasible and safe operation, which can be applied to various lung diseases. In patients with early-stage lung cancer, excellent survival can be also achieved.

Standard open procedures for resection of the first rib in thoracic outlet syndrome can prove to be quite difficult with extensive incisions. A minimal invasive procedure can also be painstaking, but provides an attractive alternative to the more radical open procedures. We report the details of the technique with direct video footage of the procedure performed in a 41-year-old man with thoracic outlet syndrome done entirely by thoracoscopic methods.

VATS is now used by many thoracic surgeons and in various anatomic locations such as lung parenchyme, pleura and mediastinum, etc. VATS of mediastinal masses has special characteristics compared to that of other diseases. Those are no positional changes of the mass during collapse of the lung and close proximity of the mass to major vascular structures, nerves and other vital organs. From 1992. July to 1993. August, 10 mediastinal masses were treated with video assisted thoracoscopy. There were five males and five females, ages ranged from 11 years to 65 years with average 37.7 17.7 years old. Of the 10 patients, 4 were bronchogenic cysts, 2 were teratoma, and the others were thymoma, neurilemmoma, pericardial cyst, and thymic cyst. Needle aspiration was done in large cysts and the working thoracotomy[or utility thoracotomy] was done in large solid masses for the purpose of easy dissection, easy handling and easy delivery of the mass. The average operation time were 155.6 6.8 minutes and the duration of air leakage were 1 2.2 days. The duration of the chest tube drainage were 3.3 2.6 days. The lengths of the postoperative hospitalization were 5.1 2.7 days which were shorter than those of 12 mediastinal masses treated with conventional thoracotomy during the same periods [p<0.05]. There was 1 patient converted to thoracotomy because of a bleeding at innominate vein. 3 postoperative complications were occured. Those were persistent air leakage for 7 days, diaphragmatic palsy and hoarseness which were recovered within 1 month. We conclude that mediastinal mass can be excised with video assisted thoracoscopy and the posthospitalization is reduced. But careful attention is required for avoiding injury to major vascular structures, nerves, and other vital organs.

기관 절개술을 시행받은 중증 근무력증 환자(Osserman's Group-ll-C-1) 2례에서 흥강내시경을 이용 하여 흉선 절제술을 시행하였다. 첫 환자는47세 남자로서 기관지 절개 부위로 기계적 보조호흡을받고 있는 상태였으며, 두번째 환자는 60세 남자로서 기계적 보조호흡치료에서 일단 회복되 였으나 다시 호흡 부전이 악화되는 상태였다. 두 예 모두 기관 절개술이 되어 있었으므로,정중흥골절골술등의 기존 방 식에 의한 수술의 경우 수술후 종격동염의 발생 가능성이 높을 것으로 예상되어 흥강내시경을 이용하 여 흉선 절제술을 시행하였다. 수술후 각각 16일째와 3일째에 기계적 보조호흡을 중단할수 있었고,종격동염의 발생없이 회복되었 다. 따라서 기관지 절개술을 시행받고 있는 중증 근무력증 환자에게 흥강내시경을 이용한 흉선 절제술 이 기존의 수술 방식을 대체할 수 있는 중요한 술식이라고 보고한다.

배경: 비디오흉강경수술은 폐를 허탈시켜 흉강내의 공간을 확보함으로써 시행되는데 흉막유착은 이러한 공간을 확보하는데 커다란 장애요인이 되어 폐손상 및 출혈을 유발할 수 있으며, 개흉술로 전환하는 원인이 되기도 한다. 흉강경수술을 시행하기 전에 흉막유착 유무를 확인하면 투관침의 위치선정 및 삽입방법을 포함한 수술과정을 계획하는데 매우 유용한 정보를 얻을 수 있다. 대상 및 방법: 2009년 6월부터 2009년 11월까지 비디오흉강경수술을 시행한 24명의 환자에서 수술 전에 흉막유착을 확인하기 위하여 초음파검사를 시행하고 흉강경수술시의 소견과 비교하였다. 검사부위는 투관침 삽입부위인 전액와선에서 후액와선까지의 흉부 측면을 주로 검사하였으며, 경우에 따라서는 흉부 전면이나 후면을 관찰하기도 하였다. 결과: 환자는 다한증 6예, 간질성폐병변 8예, 폐종양 5예, 종격동종양 2예, 말초폐동맥색전증 1예, 전이성폐종양 1예, Sarcoidosis 1예로 구성되었다. 초음파검사를 통해 흉막유착이 없다고 진단한 22예 중 4예는 검사부위와 동떨어진 곳에 일부 국한되어 경미한 유착이 있었으나 투관침 삽입부위와는 관련이 없었다. 흉막유착이 있다고 진단한 2예는 수술시 동일한 소견이었다. 수술중 투관침 삽입으로 인한 폐손상은 없었으며 개흉으로의 전환도 없었다. 결론: 초음파검사는 짧은 시간내에 검사가 이루어지며, 비디오흉강경수술을 계획하고 시행하는데 초음파를 이용한 흉막유착 여부의 확인은 매우 유익한 시술법이라고 사료된다.

Extramucosal esophagomyotomy by thoracotomy, first described by Heller in 1913 was the principal therapy for achalasia. Recently however, video-assisted thoracoscopic surgery has been implied in esophageal surgery, and we have experienced 23 year old male patient with dysphagia and was diagnosed as achalasia who underwent thoracoscopic esophagomyotomy. The esophagogram showed typical bird beak appearance and the lower esophageal sphincter pressure was increased to 35 mmHg. Thoracoscopic surgery was done twice due to incomplete myotomy in first operation and the patient was released of dysphagia in the second operation.

배경: 폐암에 대한 수술적 치료 시 흉강경을 이용한 폐엽 절제술과 림프절 절제술이 증가하고 있지만 흉강경 림프절 절제술의 유용성은 여전히 논란거리로 남아있다. 최근에 비디오 종격동경을 이용한 림프절 절제술이 폐암 환자의 종격동 병기를 결정하는데 있어서 우수한 결과를 보이고 있다. 이 연구는 좌측 폐환자에서 비디오 종격동경을 이용한 림프절 절제술과 흉강경 폐엽 절제술의 안정성과 유용성 등의 임상적 가능성에 대해 알아보고자 하였다. 대상 및 방법: 2004년 2월부터 2008년 4월까지 좌측 원발성 폐암으로 흉강경을 이용한 폐엽 절제술을 시행한 50명의 환자를 대상으로 하였다. 그 중 30명(Group A)은 비디오 종격동경과 흉강경으로 림프절 절제술을 시행받았으며, 나머지 20명(Group B)은 흉강경만으로 림프절 절제술을 시행받았다. 결과: 수술 소요시간, 흉관 거치일수 및 재원일수에 있어서 두 군간의 통계학적인 차이는 없었다. 총 림프절 절제수(p=0.001) 및 N2 림프절 절제수(p=0.013)는 A군이 B군에 비하여 많았으나 N1 림프절 절제수에서는 차이가 없었다. 수술 후 각각 2명의 환자에서 10일 이상의 지속적인 공기누출이 있었고 A군에서 폐렴이 1예, B군에서 성대마비가 1예 있었다. 수술 후 단기 사망률은 없었다. 결론: 폐암 환자에서 종격동 병기결정을 위해 비디오 종격동경을 이용한 림프절 절제술(VAMLA)이 이용되고 있다. 이번 연구를 통하여 VAMLA는 좌측 폐암수술에서 종격동 림프절 절제 시 흉강경을 이용한 림프절 절제술과 비교하여 보다 완전한 절제가 가능하다는 것을 확인하였다. 따라서 앞으로 VAMLA는 최소절개수술의 한 방법으로서 폐암의 진단 목적뿐만 아니라 치료의 수단으로 유용하게 이용될 것으로 생각된다.

Background: This study analyzed and described the clinical characteristics and surgical outcomes of diaphragmatic hernia (DH) repair according to the operative approach. Methods: After excluding cases with a combined approach and hiatal hernias, we analyzed 26 patients who underwent DH repair between 1994 and 2018. The baseline and perioperative characteristics of the thoracic approach group and the abdominal approach group were described and analyzed. Results: Fifteen of the 26 patients were treated through the thoracic approach, including 5 patients who underwent video-assisted thoracic surgery (VATS). Eleven patients underwent the abdominal approach. The thoracic approach was associated with a longer duration of DH than the abdominal approach (2 vs. 0.1 months), herniation of the right-sided abdominal organs, and herniation of the retroperitoneal organs. During the median follow-up of 23 months, there was no recurrence of DH. Conclusion: The surgical approach should be chosen considering the duration of DH and the location of herniated organs. VATS might be a safe and feasible option for repairing DH.

A 66-year-old patient undergoing regular follow-up at Samsung Medical Center after left lower lobectomy visited the emergency department around 9 months postoperatively because of nausea and vomiting after routine esophagogastroduodenoscopy at a local clinic. Abdominal computed tomography showed the stomach herniating into the left thoracic cavity. We explored the pleural cavity via video-assisted thoracic surgery (VATS). Adhesiolysis around the herniated stomach and laparotomic reduction under video assistance were successfully performed. The diaphragmatic defect was repaired via VATS. The postoperative course was uneventful, and he was discharged with resolved digestive tract symptoms.

Background: Conventional treatment (i.e. chest tube insertion and chemical pleurodesis) still remains standard for patients with secondary spontaneous pneumothorax because the risk of surgical bullectomy is deemed high in this subset. However, it has been suggested that surgical treatment using thoracoscopy may expedite postoperative recovery and, thus, may reduce hospital stay. Materials and Methods: Retrospective review of 61 patients with secondary spontaneous pneumothorax, who underwent conventional treatment (n=39) or video-assisted thoracoscopic surgery (VATS) (n=22) between January 2007 and December 2009, was performed. Talc was used for chemical pleurodesis in both groups. Results: Hospital stay of conventional treatment group and VATS group was $14.2{\pm}14.2$ days (4~58 days) and $10.6{\pm}5.8$ days (5~32 days), respectively, with statistically significant difference (p=0.033). Recurrence rate of conventional treatment group was also significantly higher (12/39, 30%) compared to VATS group (1/22, 4.5%) (p=0.016). Conclusion: In selected patients with secondary spontaneous pneumothorax with continuous air leak or inadequate lung expansion, thoracoscopic surgery with chemical pleurodesis using talc results in shorter hospital stay and lower recurrence rate compared to conventional approach.
