When compare with blebectomy or bullaectomy simply and pleurodesis together in treatment of primary spontaneous pnevmthorax, the later has been realized as the method that can reduce the recurrent rate after surgical operation. Therefore, in this study, we compared the merits and demerits of the clinical result of chemical pleurodesis that use Talcum powder in pleurodesis and mechanical pleurodesis that use apical pleurectomy and analyzed the reappearance rate etc. Material and Method: The Pleurodesis through the apical pleurectomy and talc powder insufflation had been used as secondary procedure after blebectomy of spontaneous pneumothorax from January 1, 2000 to June 30, 2002. This study consisted of a retrospective review of 68 patients who were treated with apical pleurectomy, and 84 patients treated with talc powder insufflation. We compaired the apical pleurectomy and talc powder insufflation in terms of age, sex, cause of operation, number of used autosuture staple, tine duration of procedure after blebectomy, severity of pain and complication after operation, postoperative air leakage period, duration of chest tube insertion, hospitalization, and recurrence rate of pneumothorax. Result: Time required for secondary procedure was longer in apical pleurectomy than talc powder insufflation. Postoperative pain was more severe in talc powder insufflation than apical pleurectomy. Otherwise there was no significant difference between two methods. Conclusion: Although Talc powder insufflation is more convenient than apical pleurectomy, the difference is not large and, the severity of postoperative pain is worse in talc powder insufflation. Therefore apical pleurectomy can be recommended for the secondary surgical procedure after blebectomy of primary spontaneous pneumothorax can be recommended.

Background : This report reviews our experience with persistent air leaks in the peumothorax that were not considered candidates for surgical treatment in order to evaluate the efficacy and risks of the OK-432 plus autoblood or OK-432 pleurodesis. Material & Methods : From March 2004 to July 2005, 8 consecutive patients who had an air leak in the pneumothorax over 5 days and had been treated with OK-432 plus autoblood or OK-432 pleurodesis. The patients were not considered candidates for surgical treatments because the chest CT findings revealed severe chronic lung disease with multiple bullae and/or bullous changes. A prolonged air leak with/without dead space was treated with either OK-432 plus autoblood or OK-432 pleurodesis. The efficacy and side effects of OK-432 pleurodesis were assessed by determining the duration of the air leak, the number of pleurodesis, the patients' symptoms, measurements of the white blood cell count and the c-reactive protein level. Results : All of eight patients were male and the mean age was $72.4{\pm}8.5$. The mean number of pleurodesis was $1.9{\pm}1.1$ and the mean duration of the air leak was $4.6{\pm}4.6days$ after pleurodesis. Side effects after pleurodesis were encountered in 7 patients, which included a chilling sensation in 7 cases, chest pain in 5 cases, headache in 3 cases, local heat sensation in 2 cases, and fever in 1 case. Leukocytosis was observed in 6 patients, and the mean of WBC count and CRP were $14500{\pm}2100$ and $21.9{\pm}11.4mg/dL$, respectively. Conclusion : Either OK-432 plus autoblood or OK-432 pleurodesis has acceptable side effects, and can be considered a treatment option for persistent air leaks in the pneumothorax that are not candidates for surgical treatment.

Background: Malignant pleural effusion is a common clinical problem in neoplastic patients. With the diagnosis of a malignant pleural effusion, palliative therapy was done. One of the treatments was a chemical pleurodesis. Talc was the most commonly used a sclerosing agent, but the quality of patient's life was not improved. We was evaluated by other agents such as Viscum album for relief of malignant pleural effusion. Material and Method: From November 2001 to October 2003, 17 patients who underwent to chemical pleurodesis for the malignant pleural effusion. We compared the talc (group I: 10 patients) and Viscum album (group II: 7 patients). We analysed them retrospectively in term of various factors and results. Result: There were no significant differences between group I and group II in the sex ratio, mean age, origin of primary cancer and site, but, group I had higher successful rate (80% : 71 %) than group II. Group II had better length of chest tube stay after procedure, Karnofsky performance and recurrence than group I. The failed treatement group was related to the pleural fluid pH and interval of initial chemical pleurodesis after thoracostomy. Conculsion: Although the chemical pleurodesis with Viscum album was slightly lower than talc in the successful rate, there was an alternative method instead of the chemical pleurodesis with talc to improve the patient's quality of life in malignant pleural effusion.

A 51-year-old woman was transferred from a private hospital for persistent massive left pleural effusion. Available examination methods did not reveal the cause of the disease. The pleural effusion was confirmed as chylothorax by thoracentesis and chest computed tomography. Previous tube drainage and pleurodesis had failed. Therefore we decided on an operative approach. A left thoracotomy revealed nothing abnormal except for the oozing lymph from the mediastinal pleura, which was sutured by 4-0 prolene. Decortication and pleurodesis were done at the same time. Postoperative course was uneventful and no recurrent pleural effusion was recognized for 3 months. Adult Idiopathic unilateral chylothorax with unknown etiology is rare, but this case was successfully treated with an operative method.

Background : Lung cancer is the leading cause of malignant pleural effusions, which is currently most commonly treated using pleurodesis via bedside thoracostomy. Several agents had been used for the treatment of pleural sclerosis, but with differing efficacies and associated side effects. Our purpose with this study was to compare the efficacy, side effects and disease free survival times of patients being treated with OK-432 and doxycycline sclerotherapy in lung cancer induced malignant pleureal effusions. Materials and Methods : 79 patients who underwent pleurodesis with OK-432 and doxycycline, between Jan.1994 and Aug. 2001, were retrospectively reviewed. Response 30 days following pleurodesis were determined from chest radiographs, with the disease free survival time being evaluated according to the response. Results : The success rates, 30 day followint pleurodesis, with OK-432 and doxycycline 83 and 87%, respectively (p=0.677). With regard to the side effects, fever was more common when OK-432 was used (59%, p=0.001), and pain was more common with doxycycline use (73%, p=0.008). There was no significant difference in disease free survival times between OK-432 (13.6 Months) and doxycycline (11.6 Months) (p=0.532). Conclusion : with the use of OK-432, for pleurodesis, was as effective as doxycycline, can be considered as an alternative treatment for malignant effusion in patients with lung cancer.

Background: This study was performed to evaluate the safety and efficacy of performing additional tetracycline pleurodesis during the thoracoscopic treatment of primary spontaneous pneumothorax. Material and Method: Between March 2004 and December 2007, 91 cases of primary spontaneous pneumothorax were treated by video-assisted thoracoscopic surgery. The thoracoscopic procedures included resection of the blebs and mechanical pleurodesis by scrubbing the parietal pleura. For 27 cases (Tetracycline group, group I), 20 mg/kg tetracycline was instilled into the pleural space through a trocar before closing the chest. The control group (group II) consisted of 64 cases of primary spontaneous pneumothorax for which the same thoracoscopic procedures alone were performed during the same study period. Result: There was no significant difference between the two groups in terms of the demographic data, the operative findings and the operation time. The percentage of cases that needed intravenous analgesics and the duration of intravenous analgesics were comparable in both groups. There was no significant difference in the duration of air leaks and complications between the two groups. The patients treated with tetracycline pleurodesis had a longer period of postoperative chest drainage (4.2 days vs 3.5 days, respectively, p=0.03) and hospitalization (5.0 days vs 4.0 days, respectively, p=0.006). During the follow up period, the ipsilateral recurrence rate was much lower for the patients who were treated with tetracycline pleurodesis (0% vs 10.9%, respectively, p=0.099), and freedom from recurrence tended to be more favorable for group I (p=0.077), although this was not statistically significant. Conclusion: Additional tetracycline pleurodesis during thoracoscopic treatment for primary spontaneous pneumothorax caused prolongation of chest drainage and a prolonged hospital stay. However, further investigations are needed because tetracycline pleurodesis can be performed safely without serious complications and it showed a distinct tendency to reduce the rate of recurrence.

Background: Complicated pleural space occupying lesions (SOL) have been treated by thoracentesis, closed thoracotomy drainage (CTD) or surgical intervention with using a video thoracosocpe or open thoracotomy depending on the extent of the disease. With the development of video assisted thoracoscopic surgery (VATS), VATS pleural adhesiolysis and decortication have revealed good results as compared to those for open thorcotomy. To assess the effectiveness of VATS pleural adhesiolysis and decortication, we retrospectively analyzed the medical record and radiologic findings of the patients with complicated pleural SOL and who were treated by this surgery. Material and Method: From May 1996 to April 2006, 64 patients (mean age: 41.8 years) with complicated pleural SOL underwent 65 VATS. To analyze the surgical outcome, we classified the postoperative findings on the simple chest X-rays into 4 classes as Class I: no or minimal pleural lesion, Class II: blunting of the cardiophrenic angle and mild pleural thickening, Class III: an elevated diaphgram or persistent lung collapse and Class IV: complicated or recurrent effusion. Result: Before VATS, the patients underwent the diagnostic or therapeutic procedures: single or repeat diagnostic tapping for 41, thoracoscotomy drainage for 11, pigtail catheter drainage for 10 and intrapleural fibrinolytics for 10. The mean duration between the onset of symptom and surgery was 18.4 days. There was neither mortality nor severe complications. The surgical outcomes were class 1 for 28, class 2 for 13, class 3 for 19 and class 4 for 5. There were statistically significant differences between the symptom duration and the classes, and between the operation time and the classes. Conclusion: VATS pleural adhesiolysis and decortication are effective, safe treatments for managing complicated pleural SOL, and an earlier operation is needed for obtaining a better surgical outcome.

To determine the efficacy of OK-432 as pleural sclerosant, we examined the outcomes in 81 patients (age : 27 to 82 years) with malignant pleural effusion and the outcomes in 64 patients ecieving OK-432 3-10KE(1 Klinische Einheit unit) through a chest tube for malignant pleural effusions. Of 81 patients with malignant pleural effusion, 40 patients had lung cancer. Lung cancer is the most frequent cause of malignant pleural effusion in men and women, in which 57 oyo of it was adenocarcinoma. Eighty seven percent of patient had respiratory symptom. Of the 64 patients with intracavitary injection of OK-432 for malignant pleural effusion, 59 patients had a complete short-term response (no fluid reaccumulation during 1 month after intracavitary injection of OK-432). Five patiens of the non-responders had partial control of effusion, with improvement in respiratory symptoms and these patients underwent thoracentesis. Of the 51 patients who survived longer than 1 month, 48 patients did not have re- accumulation of the fluid during follow up. Fever after intracavitary injection of OK-432 was a majors side effect although but that was easily controlled with non-steroidal anti inflammatory drug therapy, Thus the efficacy of intracavitary OK-4)2 injection for malignant pleural effusion was very helpful.
