Endobronchial metastasis of leiomyosarcoma is rare, but it can cause life-threatening complications, such as massive hemoptysis, respiratory failure or even death. The development of new endoscopic modalities allows for effective endobronchial management. We report three patients with endobronchial metastases from advanced leiomyosarcomas which caused bronchial obstruction. The bronchoscopic examinations revealed masses obstructing the left main bronchus in all three patients. After removing the endobronchial tumor via interventional bronchoscopy, there was symptomatic and radiologic improvement. Moreover, the patients were able to undergo additional palliative chemotherapy. Therefore, endobronchial management of endobronchial tumors should be considered in the treatment of endobronchial metastasis, even in patients with advanced malignancies.

Backgroud: Pneumonectomy carries the possibility of numerous dangerous complications as well as the vast effect the operation itself has on the cardiopulmonary function. Most of operations are done with the insertion of the chest tubes upon completion, but because of the high incidence of pyothorax as its complications, we have tried to analyze and compare the cases without inserting the chest tubes. Material and Method: During a 5 year period from January, 1996 to December 2000, 100 cases, which were operated at the Hanyang University Hospital, were selected using the patient's charts. The age, gender, indication of operation, associated diseases, and operation site(left or right) were classified accordingly and the postoperative complications and mortality were statistically analyzed using the $\chi$ 2-test. After resecting the lung, the intrathoracic pressure was set at -15 ~ -20cm $H_2O$ using the nelaton catheter, and the thoracotomy site was then closed. The gradual collection of the fluid and blood in the thorax of the operated side, as well as the mediastinum location, were observed carefully for 4~5 days postoperatively with the aid of the simple chest x-rays. Result: Of the 100 cases, 16 cases of pulmonary tuberculosis(16%), 81 cases of lung tumor(81%), 2 cases of bronchiectasis(2%), and 1 case of aspergilloma associated bronchiectasis were noted. There were 8 mortality cases(8%), and of the 34 cases(34%), 44 complications were noted. The age, sex, and operation site(left or right) were not statistically significant with the complications. 7 of the 16 cases of pulmonary tuberculosis(44%) and 27 of the 81 cases of lung tumor(33%) had complications, but they were found not to be statistically significant. The increase of the complication rate in the pulmonary tuberculosis patients was 3.86. The evidence of postoperative bleeding was observed in 6 cases with the 3 cases being the pulmonary tuberculosis patients and the 3 cases were others. This shows that the increase in postoperative bleeding in the pulmonary tuberculosis is statistically significant(p=0.019). Of the 100 cases, there were 8 mortality cases(8%), with 5 cases from the 81 cases of the lung tumor group(6.1%), 3 cases from the 16 cases of pulmonary tuberculoses group(18.7%).

Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard diagnostic method for mediastinal and hilar lymphadenopathy. Although rare, fatal infectious complications can occur following EBUS-TBNA. However, to date, there is a lack of effective preventive strategies to reduce these complications. We started a trial to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Methods: This study is a single-center, parallel-group, assessor-blinded randomized controlled trial (RCT). We will enroll 112 adult participants undergoing EBUS-TBNA using a convex probe, and randomly assign them to two groups at a 1:1 ratio. The intervention group will gargle for 1 minute with 100 mL of 0.12% chlorhexidine gluconate before EBUS-TBNA, while the control group will have no mouthrinse before the procedure. Immediately after completion of EBUS-TBNA on all targeted lesions with an aspiration needle, a needle wash sample will be taken by instilling 5 mL of sterile saline into the used needle. The primary outcome is colony forming unit (CFU) counts in aerobic cultures of the needle wash samples. Secondary outcomes are CFU counts in anaerobic cultures, fever within 24 hours after EBUS-TBNA, and infectious complications within 4 weeks after EBUS-TBNA. Conclusion: This trial was designed as the first RCT to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Results from this trial can provide clinical evidence for a simple, safe, and cost-effective strategy to prevent infectious complications following EBUS-TBNA (ClinicalTrials.gov ID: NCT04718922, registered on 22 January 2021).

Background: In spite of initial intensive and long-term chemotherapy for pulmonary tuberculosis, many problems remain in the treatment of the residual lesion. The role of surgical intervention for pulmonary tuberculosis is getting rid of such residual lesion of pulmonary tuberculosis to support the healing process and to induce bacteriologically negative conversion in the end. Method: We experienced 30 cases of pulmonary resection for pulmonary tuberculosis from Aug. 1994 through Apr. 1995 in National Masan Tuberculosis Hospital. We conducted retrospective study to analyze several variables for the cases. Results: 1) The ratio between male and female was 4:1(male 24, female 6) and the age of peak incidence was in 3rd and 4th decades. 2) Indications for pulmonary resection in the radiographic findings were cavitary lesions of 19 cases(63.3%), destroyed one side of 8 cases(26.7%) and destroyed one lobe of 3 cases(10%). 3) 16 of 20 cases with unilateral lesions and all of 10 cases with bilateral lesions on chest X-ray films showed AFB positive on preoperative sputum smears. 14 cases(87.5%) of unilateral lesions and 9 cases(90%) of bilateral ones were converted into AFB negative postoperatively. Negative conversion rates of pneumonectomy and lobectomy cases were 100% and 85.7%, respectively. 4) Preoperative combined disease was 3 cases(10%) of DM and postoperative complications were 2 cases(6.7%) of dead space and no death. Conclusion: Chemotherapy only has some limitation in treatment of all tuberculosis. So, surgical intervention for pulmonary tuberculosis is an effective method as partner of chemotherapy.
In the diagnostic evaluation of thoracic lesions, the image-guided transthoracic needle biopsy was developed, and its role was expanded with the development of cross-sectional detection and characterization of thoracic lesions and advances in biopsy needle design and techniques. Particularly for diagnostic evaluation of solitary pulmonary nodules, transthoracic needle biopsy has emerged as the invasive procedure of choice. This article covers the indication, the pre-procedure preparation, various guidance-modalities and techniques, and complications.

Objectives: Active pulmonary tuberculosis (active PTB) is manifested in one of the complications of pneumoconiosis, but statistics are not available. The objective of the present study was to identify the incidence of active PTB among dusty workers who were diagnosed with pneumoconiosis by year. Methods: The present study was performed using the results of the Pneumoconiosis Examination Council's assessment from the Korea Workers' Compensation and Welfare Service (KCOMWEL) database between January 1, 1984, and December 31, 2017. Pneumoconiosis is defined as Category 1 or more. Active PTB was defined as a positive result for active PTB in the result of the Pneumoconiosis Examination Council's assessment. The annual incidence rate of pneumoconiosis and active PTB were analyzed by age standardization. Results: The number of retired dusty workers who received the health examination for work-related pneumoconiosis increased every year. However, the incidence of pneumoconiosis among retired dusty workers and active PTB among patients with pneumoconiosis decreased every year. Conclusions: To effectively manage pneumoconiosis and active PTB among patients with pneumoconiosis, the annual status of them in retired dusty workers who received the health examination for work-related pneumoconiosis was required.

Objectives: Although active pulmonary tuberculosis(active PTB) is manifested as one of the complications of pneumoconiosis, attacks of active PTB among patients with pneumoconiosis is still unexplored. The objective of the present study was to identify the attack rate of active PTB among workers in dusty environments who were diagnosed with pneumoconiosis. Methods: The study was performed using the results of the Pneumoconiosis Examination Council's assessment from the Korea Workers' Compensation and Welfare Service(KCOMWEL) database between January 1, 1984 and December 31, 2017. Pneumoconiosis was defined as Category 1 or more in the radiological findings of pneumoconiosis. Active PTB was defined as a positive result for active PTB in the results of the Pneumoconiosis Examination Council's assessment. Results: A total of 37,946 workers in dusty environments who received a health examination for diagnosing pneumoconiosis between January 1, 1984 and December 31, 2017 were selected as study subjects. The attack rate of active TB among subjects who were diagnosed with pneumoconiosis and those who were diagnosed without pneumoconiosis were 8.5% and 1.4%, respectively. In the multivariate logistic analysis including age, sex, radiological findings, complications, male[odds ratio(OR), 2.0; 95% confidence interval(CI), 1.4-3.1] and pneumoconiosis(OR, 6.5; 95% CI, 5.7-7.4) were associated with an increased risk of developing active PTB. Conclusions: The present study determined that dusty workers who were diagnosed with pneumoconiosis had a high rate of active PTB compared to TB patients and patients who were diagnosed with silicosis. Therefore, in addition to silicosis, it is necessary to include pneumoconiosis among the high-risk groups for TB.

1996
Background : Known as a kind of complication or a specific form of pulmonary tuberculosis, endobronchial tuberculosis caused several kinds of problems in diagnosis and managements. But the frequency of this disease are is widely variable, generally reported from as low as 10 - 20 % to as high as 40 - 50 %. We prospectively performed bronchoscopy in patients diagnosed as pulmonary tuberculosis to evaluate the frequency of endobronchial tuberculosis and its related findings. Method : From March, 1995 to February, 1996, we prospectively performed bronchoscopy in patients newly diagnosed as pulmonary tuberculosis and evaluated the frequency of endobronchial tuberculosis, its clinical features and laboratory findings including raiologic, microbiologic and physiologic aspects. Results : Number of patients diagnosed as pulmonary tuberculosis was 103 and 55 patients(53.4%) were found to have endobronchial tuberculosis. But the frequency were 43.8% in male and 76.7% in female, respectively. Frequently noted symptoms were nonspecific including cough, sputum, fever, weight loss in the order of frequency but cough was more frequent than in pulmonary tuberculosis. Physical examination showed rale, decreased breathing sound and wheezing and wheezing was more frequent than in pulmonary tuberculosis. All 7 subtypes were noted bronchoscopically and edema-hyperemia (stenotic without fibrosis) type was most frequently(32.7%) noted, and followed by chronic nonspecific bronchitis type, stenotic with fibrosis type and actively caseating type in the order of frequency. The relationship between subtypes of endobronchial tuberculosis and radiologic findings was insignificant. Right lung was involved more frequently than left lung and left upper lobe was most commonly involved site, and followed by right upper lobe and trachea. Acid-fast bacilli(AFB) positivity in sputum and / or bronchial washing fluid was 73% and suggested high risk of infectivity. Conclusion : The frequency of endobronchial tuberculosis in patients with pulmonary tuberculosis was higher than known and also suggested bronchoscopic examination to detect endobronchial involvement should be recommanded and careful management is also needed to prevent complications.
During the last 10 years of period, one hundred patients with various pulmonary diseases were pneumonectomized upon at the Department of Chest Surgery of Pusan University Hospital. This paper is concerned with the clnical results of these patients along with the serious postoperative complications such as postoperative intrapleural infection and hemorrhage. The results were obtained as follows. 1.Left pneumonectomy was done in sixty-six of 100 patients [66 %] and the right one was done in the rest thirty-four[34 %]. The ratio between left and right was nearly 2:1. 2.Of all oostoperative complications, the intrapleural infection was most common, and these were 53 % in empyema thoracis and 12.7 % in pulmonary tuberculosis respectively. 3.More postoperative complications could be seen after right pneumonectomy than the left one. 4.It was thought that the postoperative intrapleural infection was closely correlated with the methods of pleural dissection at pneumonectomy,postoperatlve tube drainage, time of operation, massive hemorrhage during operation, prolongation of bleeding time, and dysfunction of the liver. 5.The repeated thoracenteses with infusion of neomycin into the infected thoracic cavity and intravenous administrations of the high units of penicillin were effective in treatment of the postoperative intrapleural infection, however, the refractory cases have to be cured by thoracoplasty with open window. 6.Immediate secondary open thoracotomy appears to be the method of choice in life saving who developed massive intrathoracic hemorrhage after pneumonectomy. 7.The mortality rate was 10 % in our cases and the main causes of death were postoperative respiratory insufficiency, pulmonary edema, hemorrhage and sudden cardiac arrest.
Background: Pulmonary sarcoidosis often involves mediastinal or hilar lymph nodes in the lung parenchyma. Mediastinoscopy is the gold standard for diagnosis, but it is invasive and expensive. Transbronchial needle aspiration using conventional bronchoscope is less invasive than mediastinoscopy, but its diagnostic accuracy is in question due to the blind approach to targeting lymph nodes. Transbronchial needle aspiration (TBNA) via endobronchial ultrasound (EBUS) has high diagnostic value due to direct visualization of lymph nodes and to its relatively safeness. The purpose of this study was to assess the usefulness of EBUS-TBNA in the diagnosis of pulmonary sarcoidosis. Methods: Twenty-five patients with symptoms of sarcoidosis were enrolled into this study. Core tissue was obtained for a definitive diagnosis. Endobronchial biopsy, transbronchial lung biopsy, and bronchoalveolar lavage were performed to verify diagnosis. For patients without a confirmed diagnosis after the above procedures were performed, the additional procedures of mediastinoscopy or video-associated thoracoscopic surgery were performed to confirm a final diagnosis. Results: A total 25 EBUS procedures were done and 50 lymph nodes were aspirated. Thirty-three (37) out of 50 lymph nodes were consistent with non-caseating granuloma, confirming sarcoidosis as the final diagnosis. Sarcoidosis was the final diagnosis for all 25 patients, and 21 required EBUS-TBNA for a final diagnosis. There were no complications associated with the procedure. Conclusion: EBUS-TBNA is already a well-known procedure for diagnosing mediastinal or hilar lymphadenopathy. We used EBUS-TBNA for the diagnosis of pulmonary sarcoidosis and our results showed 84% diagnostic accuracy and no complications related to the procedure. EBUS-TBNA is a reliable and practical diagnostic modality in the diagnosis of pulmonary sarcoidosis.
