A bronchopleural ~stula[BPF] is a major therapeutic challange to the thoracic surgeons due to difficulties in its management. We have experienced 9 cases of postpneumonectomy BPF, and all of them occured after the right side pneumonectomy. Seven patients underwent pneumonectomy due to lung cancer, and one patient each received pneumonectomy due to bronchiectasis and pulmonary tuberculosis. The most frequently used method of treatment was Eloesser operation which was done in 7 patients, and one had open thoracostomy and one had betadine irrigation until he died suddenly due to pulmonary vein rupture. The result of treatment was poor with five mortalities including one operative death. Two patients are in good condition in 28 months and 4 years of follow-up, but two are lost in follow-up. Tissue sealant such as Tisseel was used in three patients but seems to have no effect at all in the treatment of postoperative BPF.

steroid가 폐절제에 의한 대상성증식기의 폐장의 압력-용적곡선에 어떤 영양을 미칠 것인가를 알아보기 위해 실시한 본 실험의 결과를 요약하면 폐절제군은 대조군에 비해 폐용압률이 증가하였고 폐절제후 반대측폐장의 무게는 대조군에 비해 폐절제군이 유의하게 증가하였고 폐절제후 betamethasone을 투여한 군에 있어서는 대조군에 비해서는 증가하였으나 폐절제군보다는 적게 증가하였다. 또한 이러한 결과들은 betamethasone에 의해 폐포표면활성물질의 분비가 증가하였거나 혹은 betamethasone이 폐장실질의 결합조직의 단백대사에 영향을 미쳐 elastic recoil force가 감소하여 생긴 결과라고 생각된다.

Background: Contralateral pulmonary resection after pneumonectomy presents considerable challenges, and few reports in the literature have described this procedure. Methods: We retrospectively reviewed the medical records of all patients who underwent contralateral lung resection following pneumonectomy for any reason at our institution between November 1994 and December 2020. Results: Thirteen patients (9 men and 4 women) were included in this study. The median age was 57 years (range, 35-77 years), and the median preoperative forced expiratory volume in 1 second was 1.64 L (range, 1.17-2.12 L). Contralateral pulmonary resection was performed at a median interval of 44 months after pneumonectomy (range, 6-564 months). Surgical procedures varied among the patients: 10 underwent single wedge resection, 2 were treated with double wedge resection, and 1 underwent lobectomy. Diagnoses at the time of contralateral lung resection included lung cancer in 7 patients, lung metastasis from other cancers in 3 patients, and tuberculosis in 3 patients. Complications were observed in 4 patients (36%), including acute kidney injury, pneumothorax following chest tube removal, pneumonia, and prolonged air leak. No cases of operative mortality were noted. Conclusion: In carefully selected patients, contralateral pulmonary resection after pneumonectomy can be accomplished with acceptable operative morbidity and mortality.

Background: Lobectomy is the generally accepted standard treatment for early-stage non-small cell lung cancer (NSCLC). However, especially in elderly patients, it is often necessary to perform pneumonectomy in order to maximize the likelihood of curative treatment, although pneumonectomy is a challenging procedure. Methods: We analysed patients who were clinically diagnosed with stage I NSCLC and underwent pneumonectomy with curative intent from 2004 to 2011. The patients were divided into an elderly group (${\geq}70$ years) and a younger group (<70 years). We retrospectively analysed the outcomes of these groups of patients in order to characterize the role of pneumonectomy as a treatment for elderly patients with clinical stage I NSCLC. Results: Thirty patients younger than 70 years of age (younger group) and fourteen patients 70 years of age or older (elderly group) who underwent pneumonectomy were enrolled in the present study. The median follow-up period was 35 months (range, 0 to 125 months). The perioperative mortality rate (within 90 days after the operation) was 7.1% in the elderly group and 6.7% in the younger group (p=0.73). No significant differences between the two groups were observed regarding the occurrence of pneumonia, acute respiratory distress syndrome, cardiac arrhythmia, bronchopleural fistula, and vocal cord paralysis. The overall five-year survival rate was 79.4% in the younger group and 35.7% in the elderly group, which was a significant difference (p=0.018). The five-year disease-free survival rate was 66.7% in the younger group and 35.7% in the elderly group, but this difference was not statistically significant (p=0.23). Conclusion: Although elderly patients with early stage lung cancer showed a worse long-term survival rate after pneumonectomy than younger patients, the outcomes of elderly patients were similar to those of younger patients in terms of perioperative mortality and postoperative complications. Patients should not be denied pneumonectomy solely due to old age.

Post pneumonectomy empyema either with bronchopleural fistula or without bronchopleural fistula is an infrequent postoperative complication, but very serious and critical problem. But it is of some interest that the development of a postoperative empyema following resection for carcinoma of the lung might have a favorable effect on the survival of patients in recent speculation of the literature. We have experienced 4 cases of postoperative empyema following pneumonectomy for carcinoma of the lung at department of chest surgery, Yon Sei University, medical college during 11 years from Jan. 1968 to June 1980. Histologically, 3 cases were demonstrated squamous cell carcinoma except one oat cell carcinoma. Onset of postoperative empyema occurred over a wide range of time, from as early as the 5th postoperative day to insidious onset 6 months after pneumonectomy. The most common organisms isolated from the empyema cavities were staphylococcus aureus, pseudomonas aeruginosa and gram negative bacilli. All cases had a large number of organisms and more infections but not single infection. 2 out of 4 cases are treated with open pleural window drainage and irrigation with antibiotic`s solution 2 or 3 times per week by this time and postoperative general course is not eventful. One is alive to 2 years 3 months, another is alive to 8 years 11 months until now. And 2 out of 4 patients is survived over 4 years 10 months. Analysis of postoperative empyema complicating pneumonectomy for bronchogenic carcinoma revealed an increase in 4 year 10 months survival [50%].

Purpose: This is develop a critical pathway as an useful alternative to the previous management system in order to restriction of medical resources, high expectation of ordinary people to health and application for DRG. Method: In order to preliminary critical pathway, we analyzed 30 cases of medical records of patients who had lobectomy and pneumonectomy at the Yonsei Medical Center in Seoul. An expert validity test was taken for the preliminary critical pathway, and clinical validity test was also done. After these processes, the final critical pathway was developed. Result: Among 10 cases, one was excluded in this study due to the complication after operation. 7 of total 9 patients were discharged earlier than the expected day, 1 patient was just discharged at the expected day, and 1 patient was discharged 4 days later than the expected day at the 12th day after operation. Conclusion: The critical pathway is developed without difficulty because the posoperative management for patients with lobectomy and pneumonectomy is uncomplicated. Therefore, if it is more researched on the clinical application, then the activity of C.Q.I. will be able to sustain the patient oriented management system.

Background: Predicting postoperative lung function after pneumonectomy is essential. We retrospectively compared postoperative lung function to predicted postoperative lung function based on computed tomography (CT) volumetry and perfusion scintigraphy in patients who underwent pneumonectomy. Methods: Predicted postoperative lung function was calculated based on perfusion scintigraphy and CT volumetry. The predicted function was compared to the postoperative lung function in terms of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV₁), using 4 parameters: FVC, FVC%, FEV₁, and FEV₁%. Results: The correlations between postoperative function and predicted function based on CT volumetry were r=0.632 (p=0.003) for FVC% and r=0.728 (p<0.001) for FEV₁%. The correlations between postoperative function and predicted postoperative function based on perfusion scintigraphy were r=0.654 (p=0.002) for FVC% and r=0.758 (p<0.001) for FEV₁%. The preoperative Eastern Cooperative Oncology Group (ECOG) scores were significantly higher in the group in which the gap between postoperative FEV₁ and predicted postoperative FEV₁ analyzed by CT was smaller than the gap analyzed by perfusion scintigraphy (1.2±0.62 vs. 0.4±0.52, p=0.006). Conclusion: This study affirms that CT volumetry can replace perfusion scintigraphy for preoperative evaluation of patients needing pneumonectomy. In particular, it was found to be a better predictor of postoperative lung function for poor-performance patients (i.e., those with high ECOG scores).
