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.

Retrospective review of 26 patients undergoing open lung biopsy at the Yonsei University during 10 years period was conducted to evaluate open lung biopsy for DILD. From January 1980 to August 1990, open lung biopsy was performed in 26 patients through a limited thoracotomy incision[a limited anterior or a posterolateral thoracotomy]. Open lung biopsy was indicated for diffuse interstitial pulmonary diseases undiagnosed by indirect clinical and radiological diagnostic methods. The types of incision were limited anterior[11] and limited posterolateral[15]. Preoperative evaluation of the lung disease included sputum culture[26], sputum cytology [19], bronchoscopy[9] and TBLB[7]. In 23 patients the histologic appearances after open lung biopsy were sufficiently specific histologic pictures to confirm diagnosis. The results of the biopsies changed usual therapeutic plan in 17 patients among them. The complications were resp. insufficiency[3], pulmonary ed6ma[3], sepsis[2], and others[3] in 6 patients. Diagnosis from the open lung biopsy was included respiratory pneumonia[7], fibrosis[7], infection[5], malignancy[2], others[5]. 4 patients died of respiratory insufficiency. The causes of the other three death were not due to direct result of the biopsy itself. Open lung biopsy in the patient with a diffuse infiltrative lung disease is an one of the accurate diagnostic method and frequently leads to change of the therapeutic plans. So we conclude that open lung biopsy remains our diagnostic method of choice in diffuse infiltrative lung disease undetermined etiology.

Background: Systemic sclerosis (SSc) involves multiple organ systems and has the highest mortality among connective tissue diseases. Interstitial lung disease is the most common cause of death among SSc patients and requires closer studies and follow-ups. This study aimed to identify lung function changes and predictors of progressive disease in systemic sclerosis-related interstitial lung disease (SSc-ILD). Methods: A retrospective study extracted SSc patients from an electronic database January 2002-July 2019. Eligible cases were SSc patients >age 15 diagnosed with SSc-ILD. Factors associated with progressive disease were analyzed by univariate and multivariate logistic regression analyses. Results: Seventy-eight SSc-ILD cases were enrolled. Sixty-five patients (83.3%) were female, with mean age of 44.7±14.4, and 50 (64.1%) were diffuse type SSc-ILD. Most SSc-ILD patients had crackles (75.6%) and dyspnea on exertion (71.8%), and 19.2% of the SSc-ILD patients had no abnormal respiratory symptoms but had abnormal chest radiographic findings. The most common diagnosis of SSc-ILD patients was non-specific interstitial pneumonia (43.6%). The lung function values of diffusing capacity of the lung for carbon monoxide (DLCO) and DLCO per unit alveolar volume declined in progressive SSc-ILD during a 12-month follow-up. Male and no previous aspirin treatment were the two significant predictive factors of progressive SSc-ILD with adjusted odds ratios of 5.72 and 4.99, respectively. Conclusion: This present study showed that short-term lung function had declined during the 12-month follow-up in progressive SSc-ILD. The predictive factors in progressive SSc-ILD were male sex and no previous aspirin treatment. Close follow-up of the pulmonary function tests is necessary for early detection of progressive disease.

To confirm diagnosis and to set proper therapeutic strategy, open lung biopsies were done in 57 patients who were suspected for diffuse interstitial lung disease from January 1985 to December 1994. Among them, 35 were male and 22 were female[M:F=l.6: 1 and mean age of the patients is 53.5$\pm$ 2.3[24-81 years. Tissue for histologic studies were obtained from left lung in 33, from right lung in 24according to the distributions of the pathology. Preoperative diagnostic work-up`s were chest X-ray, CT[HRCT scan, sputum study, bronchoscopy[BAL, TBLB and PTNA and all of them were unsuccessful to confirm diagnosis. In comparison of pulmonary function tests between preoperative and postoperative values, there were no significant differences in FVC, FEV1, FEV1/FVC[p 0.05 but in AaDO2[p[0.05 . Postoperative complications including atelectasis, wound infection, pulmonary edema and respiratory insnfficiency, were shown in 5 cases[8.8% , and two of them were died of respiratory failure and sepsis[mortality rate 3.5% . Pathologic diagnosis was confirmed in 53 cases postoperatively but it was undetermined in 4[diagnostic yield rate 93.0% . In comparison between preoperative clinical diagnosis and postoperative pathologic diagnosis, new diagnosis were made in 17 cases[29.8% and preoperative tentative diagnosis were confirmed histologically in 36 cases[63.2% . In 4 cases[7.0% , however, diagnoses were not confirmed after biopsies. Therapeutic plans were reset in 46 cases[80.7% in accordance with the final diagnosis.In conclusion, open lung biopsy is recommended for a specific diagnosis and proper therapeutic plan in diffuse interstitial lung diseases because of its high diagnostic yield Irate and it`s relatively low morbidity and mortality rate in these tompromised patents.

Background: Open lung biopsy is used for diagnosis of diffuse infiltrative lung diseases (DILD), but it is invasive and relatively expensive procedure. Fluoroscopy-guided cutting needle lung biopsy (FCNLB) has merits of avoidance of admission and rapid diagnosis. But diagnostic accuracy and safety were not well known in the diagnosis of DILD. Methods: We included 52 patients (37 men, 15 women) having DILD on HRCT with dyspnea, except the patients who could be confidently diagnosed with clinical and HRCT findings. FCNLB was performed using 16G Ace cut needle (length 1.5 cm, diameter 2 mm) at the area of most active lesion on HRCT. Final diagnoses were made by the consensus. Results: The mean interval between the HRCT and FCNLB was 4.5 days. Most cases were performed one biopsy during 5~10 minutes. Specific diagnosis was obtained in 43 of 52 biopsies (83%). The most common diagnosis was nonspecific interstitial pneumonia (11 cases) and followed by cryptogenic organizing pneumonia (7 cases), diffuse alveolar hemorrhage and usual interstitial pneumonia (5 cases in each), hypersensitivity pneumonitis (3 cases), tuberculosis and drug induced interstitial pneumonitis (2 cases in each), the others are in one respectively. Mild complication was developed in 9 patients (8 pneumothorax, 1 hemoptysis). Most of complications were regressed without treatment except one case with chest tube insertion for pneumothorax. Conclusion: Fluoroscopy-guided 16 G cutting needle lung biopsy was an useful method for the diagnosis of DILD.

연구배경 : 폐장은 악성종양이 가장 잘 전이하는 장기로 대부분은 혈행성으로 하나 또는 다수의 결절형태로 나타나나, 드물게는 림프관을 따라 전파되어 흉부 X선 검사상 미만성 간질성 폐침윤 양상으로 나타나기도한다. 때로는 이러한 림프관성 전이가 원발성암의 증상이 뚜렷치 않으면서 호흡기 증상과 흉부 X선 검사상 미만성 간질성 폐침윤이 보여 다른 간질성 폐질환과의 감별을 요하는데 이러한 경우를 경기관지 폐생검으로 암종성 림프관염이 진단되었던 5예를 경험하였기에 보고하는 바이다. 방법 : 임상소견, 폐기능검사, 흉부 전산화 단층촬영, 기관지 폐포 세척술과 경기관지 폐생검 검사로 진단을 얻었다. 결과 : 종양의 원발병소는 5명중 3명이 위암이었고, 2명은 폐암으로 생각되었다. 폐기능검사상 2명의 환자에서는 폐확산능이 감소된 제한성 환기장애를 보인 반면 한명에서는 폐쇄성 환기장애를 보였다. 기관지 폐포 세척술에서는 4명의 환자에서 모두 림프구 증가소견을 보였고 세포학적 검사상 이중 한명에서는 암세포도 관찰되었다. 경기관지 폐생검 검사에서 림프관에만 국한된 암세포가 관찰되었고, 이들의 cell type은 4명이 선암종이었고, 1명은 편평 상피 암종이었다. 결론 : 드물게, 암종성 림프관염은 원발성암의 증상이 없이 미만성 간질성 폐질환으로 발현될 수 있으며, 경기관지 폐생검 검사로 쉽게 진단되어 질수 있다.

A 43-year-old woman with breast cancer who was on neoadjuvant chemotherapy presented with cough, sputum and mild fever. High-resolution computed tomography showed diffuse ground glass opacities in bilateral lungs and subpleural patchy consolidations. Initially, she was thought to have pneumonia or interstitial lung diseases such as drug-induced pneumonitis and treated with antibiotics and steroids. She subsequently got breast cancer surgery because of disease progression, and concurrent thoracoscopic lung biopsy revealed metastatic carcinoma of the lung from breast cancer. The diagnosis of suspected interstitial lung disease can be made without lung biopsy, but malignancy should always be considered and lung biopsy should be performed in the absence of a definitive clinical diagnosis.
