From January, 1980, to August, 1989, 23 patients underwent thoracotomy for treatment of pulmonary aspergillosis on the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Keimyung University. There were 12 male and 11 female patients ranging from 23 years to 61 years old[mean age, 40.7 years]. The main clinical symptoms were hemoptysis[91.3%], cough[65.2%], chest pain[34.5%]. Sixteen patients[69.6%] had simple aspergilloma and 7[30.4%] had complex aspergilloma. The most common indication for operation was a hemoptysis, indeterminate mass, chronic cough, or obstructed bronchus. Anatomical location of lesion was mainly located upper lobe [82.6%] and most of cases were managed by lobectomy. Postoperative pathologic findings showed that 13 case[56.5%] were combined with tuberculosis, two were combined with bronchiectasis and two were combined with lung tumor, but 6 cases were not combined with other disease. Early complications occurred in 33.5% of patients with simple aspergilloma and in 85.7% of patients with complex aspergilloma. But there was no hospital death.

Pulmonary aspergillosis is a relatively rare disease in Korea. Immune suppressive patients, resulting from misuse or long term therapy of antibiotics, steroid and anticancer chemotherapeutics tend to be vulnerable to pulmonary aspergillosis. This study is made to illustrate the clinical features, preoperative diagnosis and surgical role in the management is this diseases. In retrospective study of operative cases from May 1980 through July 1986, 10 cases were analysis. Hemoptysis and blood tinged sputum were the most common chief complaints. Major underlying pathology was cavitary lesion or bronchiectasis caused by pulmonary tuberculosis [5 cases]. 2 cases were disseminated form due to immune suppression. Anatomic location of lesion was in the upper lobe in half case. Systemic antifungal agent is helpful for invasive aspergillosis and Resection is the treatment of choice for localized fungus balls and symptomatic localized forms.

The Swyer-James syndrome is a relatively uncommon disease entity presented with unilateral hyperlucent lung due to hypoplasia of a pulmonary artery and bronchiectasis of the affected lung. The main finding is a hyperlucent lung with small hilar shadows on the chest X-ray. Pulmonary angiography is the standard method for diagnosis. We report a case of the Swyer-James syndrome with a brief review of literature.

A patient treated with venlafaxine for major depression developed an interstitial lung disease (ILD) with the characteristic clinical, radiological and pathological features of chronic hypersensitivity pneumonitis. A high resolution computed tomography scan demonstrated ground glass opacity, mosaic perfusion with air-trapping and traction bronchiectasis in both lungs. The pathological findings were consistent with a nonspecific interstitial pneumonia pattern. Clinical and radiological improvements were noted after the discontinuation of venlafaxine and the administration of a corticosteroid. This report provides further evidence that the anti-depressant venlafaxine can cause ILD.

Airway wall thickness is an important bio-marker for evaluation of pulmonary diseases such as stenosis, bronchiectasis. Nevertheless, an image-based analysis of the airway tree can provide precise and valuable airway size information, quantitative measurement of airway wall thickness in CT images involves various sources of error and uncertainty. So we have developed an accurate airway wall measurement technique for small airways with three-dimensional (3-D) approach. To illustrate performance of these techniques, we used airway phantom that consisted of 4 acryl tubes with various inner and outer diameters. Results show that evaluation of interpolation and deconvolution methods of airways in 3-D CT images, and significant improvement over the full-width-half-maximum method for measurement of not only location of the luminal and outer edge of the airway wall but airway wall thickness.

The inhalation of a foreign body into the tracheobronchial tree is a child is a life-threatening accident. Forgotten foreign bodies In the airways cause chronic pulmonary infections, allergic asthma, bronchiectatic changes, and lung abscess Foreign bodies that cannot be grasped by bronchoscopic forceps should be removed by thoracotomy and bronchotomy. This report describes our experience In 16 patients who were treated to remove inhaled foreign bodies from the airways after repeated bronchoscopies had been unsuccessful from 1963 to 1981 at the department thoracic surgery of Seoul National University Hospital. The surgical procedures are as follows: 12 patients bronchotomy, 2 patient pneumonectomy, 2 patients lobectomy. In these cases, the foreign bodies are 8 metallic material, 3 plastic material, 1 bean, 1 black snail, and 3 cases of no records. Bronchotomy must be performed as soon as possible in order to avoid more advanced pathologic changes In the Involved lung, such as bronchiectasis, fibrosis or abscess.

Tracheobronchomegaly or Mounier-Kuhn syndrome a is rare disease characterized by marked dilatation of the trachea and main bronchi. It is thought to be due to a congenital anomaly, but is uncertain. It has variable clinical manifestations from causing chronic respiratory infections and bronchiectasis to being asymptomatic for the lifetime. Recently, we experienced a case of Mounier-Kuhn syndrome patient with tracheal diverticulum, who had lung cancer. Our case is reported with literature reviews.

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.

폐 기관지는 외부의 공기를 폐까지 전달해주는 역할을 하고 있다. 이는 병리학적, 해부학적으로 중요한 역할을 하고 있으며, 의사들에게는 기관지의 상태를 시각적으로 쉽게 판독을 할 수 있다면 폐에서 발생하는 기관지염(bronchitis), 기관지 확장증(bronchiectasis), 폐기종(pulmonary emphysema), 결핵(tuberculosis), 기흉(pneumothorax)등 여러 가지 병명을 쉽게 판독이 가능하다. 지금까지 폐 기관지에 대한 연구가 지속적으로 진행 되었으며, 2D CT 영상에서의 주변의 밀도차가 유사한 폐실 질에서의 폐기관지를 추출해 내는 것은 어려움을 Gray-scale Reconstruction과 임계치를 이용하여 추출하였다. 이는 3D 구성을 위한 전 단계로 인체 내부의 장기를 가상의 영상을 실제와 가까운 영상으로 구현하는데 쓰인다.

Asthma is a chronic inflammatory disease of the airways characterized by varying and recurrent symptoms, reversible airway obstruction, and bronchospasm. In this paper, clinical important studies on asthma published between March 2021 and February 2022 were reviewed. A study on the relationship between asthma and chronic rhinosinusitis, bronchiectasis, and hormone replacement therapy was published. A journal on the usefulness of fractional exhaled nitric oxide for the prediction of severe acute exacerbation was also introduced. Studies on the effect of inhaler, one of the most important treatments for asthma, were published. Studies on the control of severe asthma continued. Phase 2 and 3 studies of new biologics were also published. As the coronavirus disease 2019 (COVID-19) pandemic has been prolonged, many studies have explored the prevalence and mortality of COVID-19 infection in asthma patients.
