We present a case of congenital cystic adenomatoid malformation (CCAM) in a 25-year-old male who was presented with chronic cough. Chest radiography revealed an abnormal mass-like shadow in the right lower pulmonary zone. A contrast enhanced computed tomography showed an 11 cm solid, cystic mixed mass on the right lower lobe. A right lower lobectomy was performed by video-assisted thoracoscopic surgery without complications. The gross specimen showed a massive cavitation with multiloculated cysts of varying size, consistent with CCAM, along with noticeable granulomatous inflammation. Non-tuberculosis mycobacteria were isolated from a bronchial wash specimen, and the resected tissue homogenates were positive for Mycobacterium avium-intracellulare complex by polymerase chain reaction.

Granular cell tumor(myoblastoma) of the bronchus is an uncommon benign tumor that causes pulmonary complications due to obstruction of the airways. The tumor as origianally described by Abrikossoff was considered to be muscular origin, but currently neural derivation is favored. We report a case of granular cell tumor of bronchus of 27-year-old female patient with recurrent pneumonia that is confirmed by bronchoscopic biopsy, and review the liturature.

Inferior vena cava filters are increasingly being used as an alternative to anticoagulation therapy for the prevention of pulmonary embolism. However, using an Inferior vena cava filter may result in clinically significant complications. Phlegmasia cerulea dolens is a rare disease that presents with acute complete venous occlusion due to extensive thrombosis in the lower extremity. It is characterized by intense pain, edema, decreased pulses and a cyanotic extremity. We report here on a case of phlegmasia cerulea dolens that was accompanied with disseminated intravascular coagulation (DIC) as a complication of the placement of an inferior vena cava filter in a patient who had been previously diagnosed with pulmonary embolism, and the patient had recently developed a cerebral hemorrhage due to a traffic accident.

Objective : To evaluate the surgical outcomes of ventral interbody grafting and anterior or posterior spinal instrumentation for the treatment of advanced spondylodiscitis with patients who had failed medical management. Methods : A total of 28 patients were evaluated for associated medical illness, detected pathogen, level of involved spine, and perioperative complications. Radiological evaluation including the rate of bony union, segmental Cobb angle, graft- and instrumentation-related complications, and clinical outcomes by mean Frankel scale and VAS score were performed. Results : There are 14 pyogenic spondylodiscitis, 6 postoperative spondylodiscitis, and 8 tuberculous spondylodiscitis. There were 21 males and 7 females. Mean age was 51 years, with a range from 18 to 77. Mean follow-up period was 10.9 months. Associated medical illnesses were 6 diabetes, 3 pulmonary tuberculosis, and 4 chronic liver diseases. Staphylococcus was the most common pathogen isolated (25%), and Mycobacterium tuberculosis was found in 18% of the patients. Operative approaches, either anterior or posterior spinal instrumentation, were done simultaneously or delayed after anterior aggressive debridement, neural decompression, and structural interbody bone grafting. All patients with neurological deficits improved after operation, except only one who died from aggravation as military tuberculosis. Mean Frankel scale was changed from $3.78{\pm}0.78$ preoperatively to $4.78{\pm}0.35$ at final follow up and mean VAS score was improved from $7.43{\pm}0.54$ to $2.07{\pm}1.12$. Solid bone fusion was obtained in all patients except only one patient who died. There was no need for prolongation of duration of antibiotics and no evidence of secondary infection owing to spinal instrumentations. Conclusion : According to these results, debridement and anterior column reconstruction with ventral interbody grafting and instrumentation is effective and safe in patients who had failed medical management and neurological deficits in advanced spondylodiscitis.

In spite of the establishment of chemotherapy and the gradual decrease in prevalence, pulmonary tuberculosis is still mainly treated with an operation. Through analyzing and examining some cases of surgical treatment, we hope to provide some help in treating of pulmonary tuberculosis in the future. Material and Method: By comparing four journals previously published in our department with 144 cases of lung surgery during ten years from January of 1991 to December of 2000 performed by the department of thoracic and cardiovascular surgery of the National Medical Center, we analyzed and reviewed the most recent trends and the results of the surgical treatment. Annual frequency of the operation, distribution of age, examination of sputum, adaptability and types of techniques, complications, and results of the postoperative follow-up were used as methods. Result: It was found that the annual frequency of operations had decreased. The ratio of men to women, 2:1 indicates that there are more incidences in men. Aging of patients could be speculated by the .results that the decrease in the incidence rate in the 20s age range and increase rate in the 50s age range. The range of preoperative lesions belonged mostly to far advanced and moderately advanced tuberculosis. By monitoring the period of use in preoperative antituberculosis drugs, cases for more than 3 years remarkably increased from 16.0 % to 55.6 %. The positive reactive rate for preoperative sputum examinations were drastically decreased from 91 % to 27 %. Total pulmonary destruction and partial destruction were the most common cases in terms of adaptability to the operations and there were significant increases in forming empyema accompanied by parenchymal lesions from 4.0 % to 20.1 %. Pneumonectomy and pulmonary lobectomy were the major type of operations. Especially, there were increases in the incident rate of empyema and recurrence of tuberculosis resulted. Post operative follow-up indicates that the rate of complete recovery was more than 70 % and the rate of gradual increase in treating with persistent antituberculosis drug was from 5.8 % to 18.0 %. Conclusion: In recent cases, there is an increasing number of patients showing tolerance to chemotherapy. Patients with pleural tuberculosis and severe lesions were typically increased. It is important to accurately analyze those complaints accurately that are mostly difficult to be treated medically. Surgical treatment is strongly recommended Before multiple drug resistance occurs.

The incidence of traumatic rupture of the tracheobronchial tree has been increased considerably with advent of widespread mechanization and high speed era. Rupture of the bronchus is an unusual result of nonpenetrating trauma to chest. Early diagnosis and primary repair not only restore normal lung function but also avoid difficulties and complications associated with delayed diagnosis and repair. These complications are pneumonia, atelectasis and lung abscess secondary to the bronchial obtruction. We experienced a case of partial rupture on left main bronchus caused by nonpenetrating blunt chest trauma with rib fractures 1 year ago. He was suffered from progressively developing dyspnea on exercise and treated as bronchial asthma at other hospital. Bronchoscopic finding was the narrowed lumen of left main bronchus at 1cm from carina by web-like membrane. We confirmed by bronchogram and repaired by end to end anastomosis, which is rare delayed finding in bronchial rupture without pulmonary complications. We report a case of nonpenetrating traumatic bronchial rupture, manifested by bronchial web in bronchoscopy.

Background: Pulmonary aspergilloma is relatively common in korea. It arises from the colonization and proliferation of Aspergillus in preexisting lung parenchymal cavities, in particular tuberculosis. The most common symptom in this disorder is hemoptysis, which mayor may not be massive and life threatening. A routine chest radiography and computed tomography (CT) are the most important diagnostic procedures. A surgical resection of the aspergilloma has recently been recommended, because of the relatively low incidence of postoperative complications than in the past. A more concentrated sample of patients with aspergilloma, who either underwent a thoracotomy or tested positive for aspergillus antibodies, were reviewed. Method : The medical records of twenty-two patients with aspergilloma, who had a proven thoracotomy (9 cases), or who tested positive for the diagnostic procedure and/or aspergillus antibodies (13 cases) from January 1995 to December 2000, were reviewed retrospectively. Results : The most common underlying lung disease was a current or old healed tuberculosis, and 3 patients had cultures of mycobacterium other than tuberculosis (MOTT). The mean time until the aspergilloma was detected 5.91 years in the healed tuberculosis cases. The others cases involved a lung abscess, bronchiectasis and without lung disease. The extrapulmonary disease was alcoholism and diabetes. Hemoptysis was most common in 72.7%. A computed tomography (CT) is useful for diagnosis. The right upper lobe, especially the posterior segment, is the most common location. Bronchial artery embolization is ineffective for a long term follow-up. A lobectomy is most common in a thoracotomy, and intra-operative and post-operative complications are rare. During follow-up, the mortality rate, not from the aspergilloma but from respiratory failure, was 13.6%. Conclusion : Aspergilloma is a common cavitary lung disease, It mainly arises from tuberculosis, either current or healed, but extra-pulmonary disease including alcoholism or diabetes are other possible risk factors. Their most common problem in aspergilloma is hemoptysis. Surgery has a low risk of post-operative complications and is recommended in relatively preserved lung function or healthy patients. Medical maneuvers including embolization, and the local insertion of certain materials needs to be studied more closely.

Background : Bronchoscopy in patients on mechanical ventilation is being performed much more frequently. However, there is little data on the changes in physiologic parameters and no established mechanical ventilation protocol during bronchoscopy. A decreasing or the removal of positive end-expiratory pressure (PEEP) during bronchoscopy may precipitate severe hypoxemia and/or derecruitment. Methods : Our standardized mechanical ventilation protocol, without changing the PEEP level, was used during bronchoscopy. The physiological parameters were measured during the bronchoscopic procedure. Results : During bronchoscopy, respiratory acidosis, elevation of peak pressure, elevation of heart rate and auto-PEEP were developed, but were reversible changes. Procedure-related gross barotraumas or other severe complications did not developed. Conclusion : No serious complications developed during bronchoscopy under our standardized mechanical ventilation protocol when the PEEP level remained unchanged. The procedure time should be kept to a minimum to decrease the exposure time to undesirable physiological changes.

Background: Even today when chemotherapy has been established as a treatment for tuberculosis and the prevalence of tuberculosis is gradually decreasing, multi-drug resistance tuberculosis still results in poor treatment performance and lowered survival periods. This research sought to analyze the surgery of multi-drug resistance tuberculosis, and determine the usefulness and danger of surgery in connection with this disease. Material and Method: Starting from February 1990 to February 2002, retrospective surveys were conducted targeted at 21 cases involving 20 patients who underwent surgery due to multi-drug resistance tuberculosis. The survey included 14 males cases and 6 females cases with the age averaging 42.8$\pm$12.1 years. 10.3$\pm$7.6 years on average passed after patients were initially diagnosed with tuberculosis. 13 patients (65%) tested positive in the pre-operative sputum AFB test, and all showed resistance against an average of 3.5 anti-tuberculosis agents including INH and RFP. Pre-operative radiologic examinations revealed cavitary lesions in 15 patients (75%), and three patients had lesions in the both lung fields, with the major lesions existing in the unilateral area. 13 patients (75%) failed negative conversion with medical treatment, while two patients (10%) with recurrent hemoptysis and five patients (25%) with lesions involving high recurrence-rate received the operation. Operations included nine cases (40%) of pneumonectomy, nine cases (45%) of lobectomy, and three cases of lobectomy with segmentectomy. The average follow-up period of patients stood at 23 months. Result: There was no post-operative death, and found were a total of eleven cases involving complications were found: three cases of long-term air leakage, three cases of bleeding requiring re-operation, two cases of empyemas due to broncho-pleural fistula, and one case of atelectasis, wound infection and chest wall fistula each. Eleven cases (85%) of negative conversion were completed immediately after the operation, and two cases failed negative conversion. Eleven months after the operation, the disease recurred in one case of negative conversion patients, and the patient was cured by completion pneumonectomy. Conclusion: If patients' lung function was sufficient and appropriate resection was possible, multi-drug resistance tuberculosis could achieve high-rate negative conversion and cure using combination of surgical and medical treatment, and also there were not many serious complications.

Tuberculosis in children is an important disease because of higher incidence and mortality, especially in developing and underdeveloped countries. The objectives of this study were to evaluate the cause of antituberculosis medication in children and to find out the basic data for proper drug regimen. We reviewed the medical records of 198 patients who had been treated with antituberculosis drugs from Jan. 1991 to Dec. 1993 in Anam Hospital of Korea University Medical Center. The results are as following; 1) Of 198 patients, 69 cases(34.8%) had treated due to BCG complications. They were all medicated with INH. The durations of medication were 3 months in 46 patients(66.7%), 4~6 months in 17 patients(5.8%), 7~9 months in 4 patients(5.8%), 10-12 months in 2 patients(2.9%). 2) Of 198 patients, 68 cases(34.3%) had treated due to chemoprophylaxis, 59 patients (29.8% of all cases) had histories of house hold contact. Of 68 cases, 51 patients (86.4%) were medicated with INH only, 8 patients (13.6%) were medicated with INH and RFP. 3) Other causes of antituberculosis medication were tuberculous lymphadenitis(14.1%), pulmonary tuberculosis(10.6%), meningitis, miliary tuberculosis(2.0%), and pleurisy(2.0%). Most common causes of antituberculosis medications in children were complication of BCG vaccination and chemoprophylaxis after household contact. So early detection of adult tuberculosis and development of convenient diagnostic methods and safe vaccine for childhood tuberculosis is necessary.
