Objectives: To evaluate the safety, efficacy, and invasiveness of lobectomy by video-assisted thoracoscopic surgery (VATS) in the treatment of stage I/II non-small cell lung cancer (NSCLC). Methods: A total of 148 patients presenting with Stage I or II NSCLC were enrolled into our study, comprising 71 who underwent VATS and 77 patients undergoing conventional thoracotomic lobectomy, in combination with systematic lymph node resection. Results: It was found that VATS was superior to conventional thoracotomy in terms of the duration of surgery, intraoperative blood loss, frequency of the need to administer postoperative analgesia, thoracic intubation indwelling time, post-operative hospital stay, and survival rate (P<0.05). We saw no obvious difference in the number of resected lymph nodes with either approach. Conclusions: VATS lobectomy is a safe and reliable surgical approach for the treatment of Stage I/II NSCLC, characterized by significantly minimal invasiveness, rapid post-operative recovery, and markedly lower loss of blood.

Lobectomy is considered the standard strategy for early-stage non-small cell lung cancer (NSCLC). However, sublobar resection for NSCLC has recently received increased attention. The objective of this study was to compare 5-year survival, recurrence-free survival, postoperative mortality, and postoperative morbidities in patients who received segmentectomy versus those who received lobectomy through a meta-analysis. Sixteen studies were included and the combined hazard ratios or odds ratios were calculated. The results revealed that the 5-year survival rate after segmentectomy was comparable to that of lobectomy for stage IA NSCLC. However, segmentectomy for stage I NSCLC had lower rates of postoperative mortality and morbidities than lobectomy.

Although organ transplants have become quite common, combined heart-lung transplantation (CHLTx) is unfamiliar at most institutions. While the remarkable rate of development in treatment options, such as drugs and mechanical circulatory support, have reduced the need for CHLTx, it remains the sole treatment option for a subset of patients with end-stage cardiopulmonary failure. For many cardiothoracic surgeons, CHLTx is not technically new or difficult, but it does pose challenges due to its low frequency and relative complexity. Thus, this review aims to describe the CHLTx technique in technical detail using the existing literature.

The shortage of donor lungs has become a serious obstacle to implementing lung transplantation (LTx). Donation after circulatory death (DCD) donors are among the several donor pools utilized to overcome the problem posed by the shortage of donation after brain death (DBD) donors. The active use of DCD donors is expected to significantly reduce mortality on the waiting list for LTx, as LTx from DCD donors has comparable outcomes to LTx from DBD donors. Further studies on efforts to shorten the warm ischemic time and use uncontrolled DCD are required.

이차성 자연 기흉은 흉강경 수술의 좋은 적응증이다. 이 방법은 흔히 전신마취와 일측폐환기를 필요로 한다. 그러나 전신마취와 일측폐환기가 위험성이 큰 환자도 있다. 대상 및 방법: 1999년 9월부터 2001년 8월까지 15명의 고위험군 환자를 대상으로 경막외 마취하에 흉강경수술을 시행하였다. 결과: 15명이 성공적으로 흉강경 수술을 마쳤다. 술 후 누출 기간은 평균 4.3일이었고, 의미 있는 합병증은 없었으며 재발도 없었다. 결론: 흉강경 수술은 고위험인자를 가진 이차성 자연 기흉환자의 치료로 경막외 마취하에 안전하게 시행할 수 있다.

Herein, we report a case of lung transplantation in a patient with profound preoperative hypercapnia, focusing on the cardiopulmonary bypass strategy used for brain perfusion during the operation. We applied the pH-stat method for acid-base regulation, and thereby achieved the desired outcome without any neurologic deficit.

The purpose of present study is to investigate the significance of preoperative evaluation with perfusion lung scintigraphy in patients with lung cancer. Lung scans with the use of macroaggregated human serum albumin labeled with technetlum-99m were carried out in 35 patients with lung cancer before thoracotomy at Seoul National University Hospital during the period from November 1981 to September 1983. The relationship between size of the perfusion defect as seen by perfusion lung scan and size of the mass lesion as seen radiologically was correlated with the presence of regional adenopathy and resectability. Among patients with a larger perfusion defect than mass lesion on chest X-ray film.86% were found to have regional lymph node involvement with 29% resectability, whereas among patients in whom a larger defect was not present only 14% had such extension of the disease with 93% resectability. The relative pulmonary arterial perfusion of affected lung was calculated from the counts of radioactivity recorded from affected lung on both anterior and posterior scans expressed as a percentage of the total counts in the scan. The mean relative pulmonary arterial perfusion of the inoperable group [34\ulcorner%] is significantly different from both that of the pneumonectomy group [39\ulcorner%] and that of the lobectomy group [48\ulcorner%].(p<0.01)

Open lung biopsy was performed in thirty patients for the diagnosis and staging evaluation of interstitial lung disease during the period from January 1987 until December 1992. The age of the patients ranged from 14 to 71 years [mean 48 years], and the patients consisted of 14 males and 16 females. Preoperative FEV1`s were from 0.80 liter to 3.88 liters [mean 1.66]. Other non-invasive diagnostic studies such as PCNA, bronchoalveolar lavage, TBLB, and gallium scan were also done in addition to X-ray and high-resolution chest CT. Tweaty-eight were correctly diagnosed and 2 cases were not [diagnostic yield rate 93.3%]. Among the 28 cases,pathologic diagnosis influenced further treatment regimens and prognostic expectations in 23 cases [82.1%]. The diagnostic non-invasive studies other than open lung biopsy yielded a correct diagnosis without staging only in 5 cases. There was no mortality and only one complication, ARDS ; however, the patient recovered after 5 days ventilator support. Open lung biopsy, which is the gold standard for the diagnosis and staging evaluation of interstitial lung disease can be done safely and has value in clinical decision making. Also knowledge of the involvement of the lesion is important for proper selection of the biopsy site.

말기 폐기종 환자에 대한 치료로 폐이식이 가장 효과적인 방법으로 받아들여지고 있으나 장기 공여자를 구하기가 쉽지 않고 다른 장기에 비해 비교적 건강한 폐를 얻기가 매우 어려운데다가 키와 몸무게, 흉곽크기 등을 고려한 장기 크기의 적합성을 맞추기는 더욱 힘들다. 공여자의 폐가 절대적으로 부족한 상황에서 일측 폐이식술이 양측 폐이식술에 비해 많이 시행되고 있는 추세이며 수술 결과에 따른 장기 생존율에 있어서도 큰 차이가 없는 것으로 보고되고 있다. 최근에는 폐이식 수술 시 흉곽크기 등을 고려한 장기 크기 측정보다는 기능적 기준으로서 나이, 성별, 키를 변수로 한 예측 총폐활량이 보다 적절한 평가방법으로 받아들여지고 있다.

We have experienced a case of leiomyoma in the right upper lobe of the lung in a 56 year old female. Preoperative studies revealed the tumor nature as benign, and we chose right upper lobectomywith video-assisted thoracoscope rather than with the usual posterolateral thoracotomy. Postoperativehistological diagnosis was pulmonary leiomyoma which is a rare type of benign lung tumor.
