Background: Recent advance in video technology, endoscopic equipments, and surgical techniques have expanded the use of thoracoscopy from diagnosis of the pleural diseases to treatment of the various intrathoracic diseases. Video Assisted Thoracoscopic Surgery(VATS) is a pretty new and fascinating thoracic surgical modality, and so we present our early VATS resuls. Methods: Using Video Thoracoscopic techniques in 30 patients for 10 months from July 1992 to April 1993, we had performed a variety of procedures. These incuded (1) bleb resections in 18 patients (19 cases), (2) mediastinal tumor excision in 4, (3) lung biopsies for parenchymal pulmonary disease in 3, (4) pleural biopasies in 3, (5) pleural tumor excision in 1, (6) and pleuropericardial window in 1. Results: There were no mortality associated with the procedures. We had minor 8 complications; prolonged air leak in 3 patients, prolonged serous drainage in 2, recurrence of pneumothorax in 1, Honer's syndrome in 1, and hoarseness in 1 patient. None of the 30 patients had reverted to the conventional full thoracotomies. Mean postoperative hospital stay of non-complicated pneumothoraces was about 5 days, which was a little shorter than conventional thoracotomy group. Conclusion: Though we had somewhat higher postoperative complication rate due to lack of experiences in the begining, we were able to convince that VATS had benifical value for patients; lesser postoperative pain, shorter hospitalization, quicker recovery time, and cosmetically superior scar. The role of VATS can be expanded to the diagnosis and treatment of various thoracic diseases, even to the cardiovascular diseases, with satisfactory outcome and less postoperative morbidity.

Thoracic endometriosis is an uncommon disease that has four main forms: catamenial pneumothorax, hemothorax, hemoptysis, and pulmonary nodules. Since the growth of endometrial tissue depends on the presence of estrogen, thoracic endometriosis usually occurs in menstruating women between 25 and 35 years of age. Menstrual disturbances are common in women with chronic kidney disease (CKD). However, they could be reversed after kidney transplantation. Therefore, previously asymptomatic endometriosis may become symptomatic after kidney transplantation. A 49-year-old woman with CKD underwent kidney transplantation. A month later, she experienced dyspnea, and hemothorax in her right hemithorax. However, there was no evidence of infectious diseases and malignancy in thoracentesis, pleural biopsy, and computed chest tomography (CT). The serum and pleural fluid levels of his carbohydrate antigen 125 were elevated. Hemothorax secondary to pleural endometriosis was suspected. We tried hormonal therapy, and the hemothorax disappeared. At the sixth-month follow-up, there was no recurrence of hemothorax.

Primary effusion lymphoma (PEL) is a rare type of lymphoma that arises in the body cavity without detectable masses. It is associated with human herpes virus-8 (HHV-8), Epstein-Barr virus (EBV), and human immunodeficiency virus (HIV). Recently, PEL unrelated to viral infection has been reported and it has been termed HHV-8 unrelated primary effusion lymphoma-like lymphoma (HHV-8 unrelated PEL-like lymphoma). Here, we report a case of HHV-8 unrelated PEL-like lymphoma in an 80-year-old woman. Chest X-ray and computed tomography revealed left-sided pleural effusion. Pleural effusion analysis and mediastinoscopic biopsy showed atypical cells that had originated from the B cells. The cells were positive for CD20 and bcl-2, but negative for CD3, CD5, CD21, CD30, CD138, epithelial membrane antigen, and HHV-8. Serological tests for HIV and EBV were negative. Considering the patient's age, further treatments were not performed. She has shown good prognosis without chemotherapy for more than 18 months.

Background : Determining the cause of an exudative pleural effusion is sometimes quite difficult, especially between malignant and tuberculous effusions. Twenty percent of effusions remain undiagnosed even after a complete diagnostic evaluation, including pleural biopsy. The activity of tumor necrosis factor-alpha (TNF-${\alpha}$), which is the one of proinflammatory cytokines, is increased in both infectious and malignant effusions. The aim of this study was to investigate the diagnostic efficiency of TNF-${\alpha}$ activity in distinguishing tuberculous from malignant effusions. Methods : 46 patients (13 with malignant pleural effusion, 33 with tuberculous pleural effusion) with exudative pleurisy were included. TNF-${\alpha}$ concentrations were measured in the pleural fluid and serum samples using an enzyme-linked immunosorbent assay (ELISA). In addition, TNF-${\alpha}$ ratio (pleural fluid TNF-${\alpha}$ : serum TNF-${\alpha}$) was calculated. Results : TNF-${\alpha}$ concentration and TNF-${\alpha}$ ratio in the pleural fluid were significantly higher in the tuberculous effusions than in the malignant effusions (p<0.05). However, the serum levels of TNF-${\alpha}$ in the malignant and tuberculous pleural effusions were similar (p>0.05). The cut off points for the pleural fluid TNF-${\alpha}$ level and TNF-${\alpha}$ ratio were found to be 136.4 pg/mL and 6.4, respectively. The sensitivity, specificity and area under the curve were 81%, 80% and 0.82 for the pleural fluid TNF-${\alpha}$ level (p<0.005) and 76%, 70% and 0.72 for the TNF-${\alpha}$ ratio (p<0.05). Conclusion : We conclude that pleural fluid TNF-${\alpha}$ level and TNF-${\alpha}$ ratio can distinguish a malignant pleural effusion from a tuberculous effusion, and can be additional markers in a differential diagnosis of tuberculous and malignant pleural effusion. The level of TNF-${\alpha}$ in the pleural fluid could be a more efficient marker than the TNF-${\alpha}$ ratio.

The management of malignant pleural effusion is a difficult problem. Tetracycline was probably the most commonly used sclerosing agent, but parenteral tetracycline is no longer available. This prospective study was designed to determine the efficacy of insufflated talc in producing plerodesisin patients with malignant pleural effusions. Fifteen patients managed between March 1995 and March 1997 underwent thoracoscopy and had 4 gm sterile asbestos-free talc insufflation throughout the pleural space. The mean interval between the procedure and last follow-up was 101 days(range: 25-233 days). The results of treatment were clinically and radiologically compared with pre-operative status. The results were as follows: 1. The patients were 6 men and 9 women with a mean age of 55.1 years(range: 31-74 years). The primary tumors were lung cancer in 10 patients, breast cancer in two, hepatoma in one, stomach cancer in one, and adenocarcinoma of unkown origin in one. 2. Cancer cell positive ratio was 36% in sputum cytology study and 100% in thoracoscopic biopsy. 3. Symptoms improved in 94% of patients treated by talc pleurodesis. 4. After 30 days of the procedure, there was radiologically no recurrence of plural fluid in 94% patients. 5. There were wound infection in one, respiratory failure in one. In conclusion, the insufflation of 4 gm sterile asbestos-free talc in the pleural space is an effective method to control malignant pleural effusions and patients selection is important factor for reexpansion the lung.

Successful treatment of multi-loculated pleural effusion or thoracic empyema requires effective drainage and definitive diagnosis of causative organism. The purpose of this study was to assess the efficacy of the video-assisted thoracoscopic surgery in the management of thoracic empyema or multi-loculated pleural effusion after chest tube drainage treatment had failed. Material and Method: Between April 2000 and July 2002, 20 patients with thoracic empyema or multi-loculated pleural effusion that failed to chest tube drainage or other procedures who underwent an operation. All patients were assessed by chest-computed tomogram and underwent video assisted thoracoscopic drainage, debridement, biopsy and irrigation of pleural cavity. Result: In 18 cases (90%), underwent successful video-assisted thoracoscopic surgery. In 2 cases, decortications by mini-thoracotomy were necessary. The ratio of sex was 4 : 1 (16 male: 4 female), mean age was 48.9 years old (range, 17∼72 years), mean duration of postoperative chest tube placement was 8.2 days (range, 4∼22 days), mean postoperative hospital stay was 15.2 days (range, 7∼33 days). Causative disease was tuberculosis, pneumonia, trauma and metastatic breast cancer, There were no major postoperative complications. Symptoms improved in all patients and were discharged with OPD follow up. Conclusion: In an early organizing phase of empyema or multi loculated pleural effusion, video-assisted thoracoscopic drainage and debridement are safe and suitable treatment.

Percutaneous transthoracic fine needle biopsy is a popular technique in the diagnosis ot'pulmonary and pleural diseases and its complication rate is very low. One of the rarest but potential complications is that of implantation of malignant cells along the needle tract and subsequent development of a chest wall mass . We experienced a case of chest wall implantation of lung cancer after percutaneous transthoracic fine needle biopsy. The patient was a 59 year old female who had undergone right upper lobectomy for squamous cell carcinoma of the lung (T,N,Mo). 6 months after operation, a loculated mass was palpated at the right posterior .chest wall where the percutaneous transthoracic fine needle biopsy had been performed before operation. We carried out wide excision of this mass and confirmed squamous cell carcinoma histopathologically.

Background : Pleural effusions are generally divided into transudates and exudates. If it is exudative, more diagnostic tests are required in order to determine the cause of the local disease. A malignancy is a common and important cause of exudative pleural effusions. Because the pleural fluid cytology and pleural biopsy specimens do not provide a diagnosis in a high percentage of malignant effusions, several tumor markers have been examined. In order to overcome this limitation, this study hypothesized that C-reactive protein(CRP) and vascular endothelial growth factor(VEGF) measurements would be useful for differentiating trasudates from exudates and determining the differences between a benign and malignant effusion. Methods : Eighty consecutive patients with a pleural effusion (tuberculous 20, parapneumonic 20, malignant 20, transudative 20) were examined prospectively: 60 of them were classified according to Light's criteria as having an exudative fluid and 20 had a transudative fluid. The standard parameters of a pleural effusion were examined and the serum and pleural effusion VEGF levels were measured using enzyme linked immunosorbent assay(ELISA). CRP in the serum and pleural fluid was determined by a turbidimetric immunoassay. Results : The pleural CRP levels in the exudates were significantly higher than those in the transudates, $4.19{\pm}4.22mg/d{\ell}$ and $1.29{\pm}1.45mg/d{\ell}$, respectively. The VEGF levels in the pleural effusions were significantly elevated in the exudates compared to the transudate, $1,011{\pm}1,055pg/m{\ell}$ and $389{\pm}325pg/m{\ell}$, respectively. The VEGF ratio in the exudative effusion is significantly higher than a transudative effusions, $3.9{\pm}4.7$ and $1.6{\pm}0.9$, respectively. The pleural CRP levels in the patients with a benign effusion($4.15{\pm}4.20mg/d{\ell}$) were significantly higher than those in the malignant effusion($1.43{\pm}1.91mg/d{\ell}$). The VEGF ratio is significantly higher in malignant effusions($4.9{\pm}5.5$) than in benign effusions($2.8{\pm}3.6$). Conclusion : In conclusion, the CRP and VEGF levels in the serum and pleural effusion can distinguish between transudates and exudates. Moreover it can differentiate between benign and malignant pleural effusions.

A 29-year-old female patient presented with exertional dyspnea that she had suffered with for 2 months. The chest X-ray displayed right pleural effusion that was diagnosed as chyle, according to the level of cholesterol and triglyceride in the pleural fluid. VATS (video assisted thoracic surgery) of the right lung was performed on the 7th day of hospitalization for obtaining a lung biopsy and to control the of pneumochylothorax. On the 11th hospitalization day, VATS of left lung was also performed to control the recurrent pneumothorax via pleurodesis. The lung biopsy showed moderate amounts of spindle-shaped and rounded cells (so-called LAM cells), which were reactive to actin and HMB45 (on immunohistochemical stains). We report here on a rare case of lymphangioleiomyomatosis combined with chylothorax and bilateral pneumothroraces.

A clinical analysis was performed on 52 cases of tuberculous pleurisy experienced in the department of thoracic and cardiovascular surgery and department of medicine, Chosun University Hospital during a period from Jan. 1994 to Dec. 1995. Among them, male was 39 cases, female was 13 cases, with age ranged from 7 to 73 years. The common symptoms were chest pain 75%, dyspnea 59.6%, cough 55.8%. The most common diagnostic tool was pleural biopsy. The protein levels in the tuberculous pleural effusion were 0.9∼6.5 gmojo, and ratios of effusion protein to serum protein were 0.48 ∼ 1.06. The glucose levels in the tuberculous pleural effusion were 37∼ 112 mg%. The LDH levels in the tuberculous pleural effusion were 80 ∼ 2440 unitlml, and ratios of tuberculous p eural effusion LDH to serum LDH were 0.48 ∼ 1.03. The ADA levels in the tuberculous pleural effusion were 24-63 lU/L. The common surgical methods of treatment in the tuberculous pleurisy were closed thoracostomy in 18 cases(66.7%), and thoracentesis in 5 cases(18.5%). This study compares the clinical results of group A and group B. There were no significant differences for age and sex, lag period from initial symptoms to admission, diagnostic method, and protein, pH, LDH, glucose, ADA levels in tuberculous pleural effusion. Authors noted that the discharge after admission on the tuberculous pleurisy was more faster in patients with surgical treatment than in patients with only medical treatment.
