The procedure and results of thoracoscopy by using a fiberoptic bronchoscope and rigid cold-light thoracoscope in 76 cases with chest diseases of unknown causes were reported. The positive diagnostic rate was 89.5% (68/76). The histologic diagnosis following thoracoscopic biopsy in 65 patients was compared with the findings at follow-up, the results showed the sensitivity being 87.7%, specificity 100% and diagnostic accuracy 89.2%. 3 cases with persistent or recurrent spontaneous pneumothorax were cured by Nd-YAG laser transendoscopically. 5 patients with malignant pleural effusion were treated with intrapleural talcum powder under thoracoscopic control, 4 of them obtained complete pleurodesis. There were only minor complications: transient fever in 40 cases and local subcutaneous emphysema in 7. It was concluded that thoracoscopy is simple, safe, reliable and practical in the diagnosis and treatment of chest diseases. It should be popularized clinically.

In recent times minimally invasive surgery has secured a firm place among the therapeutic options in thoracic surgery. The experience and results gained from video-assisted surgery on 109 patients between January 1, 1992 and July 31, 1993 are critically discussed. The procedure could be completed thoracoscopically on 94 of them. A change of method was necessary nine times for technical reasons and six times for oncological reasons (two times due to metastasis, four times due to bronchial carcinoma). A total of 154 individual operations were conducted. Sixty-three patients with recurrent spontaneous pneumothorax were successfully treated. The relapse rate was 1.5%. With the exception of three rethoracotomies (one due to postoperative hemorrhaging and two to persistent fistula) no significant complications occurred. Further indications included capsulated pleural empyema (n = 1), persistent hematothorax (n = 2), pleurectomy for malignant pleural effusion (n = 2), pleural tumors (n = 3), pulmonary parenchyma (n = 2), interstitial lung diseases (n = 3), bullous emphysema (n = 2), peripheral lung nodules (n = 18), mediastinal tumors (n = 8), and sympathectomy (n = 2). The advantages of video-assisted thoracoscopic surgery for patients include cosmetic considerations, low pain, earlier postoperative mobilization, and for some indications, a shorter operation period. The significant disadvantages for the surgeon are the loss of binocular vision as well as the impossibility of intraoperative palpation.

To assess the value of thoracoscopy in malignant pleural effusions, the procedure and results of thoracoscopy by using a fiberoptic bronchoscope and a rigid cold-light thoracoscope in 130 cases with malignant pleural effusion are reported. The overall diagnostic rate was 91.5% (119/130). The malignant pleural mesothelioma in 24 cases and metastatic cancers in 95 cases were histopathologically confirmed. Talcum powder, tetracycline and Corynebacterium parvum were separately sprayed through thoracoscope into pleural cavity in 69, 10 and 10 patients, and the success rates of complete and lasting pleurodesis were 87.0%, 5/10 and 8/10 respectively. Postoperative complications included transient fever and chest pain, local subcutaneous emphysema in 6 cases and tumor seeding at thoracoscopy site in 4 cases. It is concluded that thoracoscopy is simple, safe, reliable and of high practical value in the diagnosis of malignant pleural effusions and in assessment before exploratory thoracotomy, and that transendoscopical administration of drugs for pleurodesis is a very effective method for controlling malignant pleural effusions. The efficacy of the talc poudrage is better than tetracycline and Corynebacterium parvum.

Management of recurrent malignant pleural effusion associated with trapped lung syndrome remains problematic. An alternative treatment using a pleural catheter has been advocated. Between August 1999 and August 2002, 127 patients underwent thoracoscopy for malignant pleural effusion. Of these, 52 (41%) with trapped lung were managed by insertion of a pleural catheter. Mean age was 66 years (range, 42-89 years). The most frequent diagnosis was breast cancer. Spontaneous pleurodesis (drainage < 10 mL) occurred in 25 (48%) patients whose catheter was removed after 30 to 255 days (mean, 93.8 days). Symptomatic relief was achieved in 49 (94%) patients. Mean dyspnea score improved significantly from 3.0 to 1.9. Complications comprised catheter blockage, surgical emphysema, cellulitis, and loculated effusion in 2 patients each. Mean length of hospital stay was 3 days (range, 1-16 days). Median survival was 126 days (range, 10-175 days). We conclude that long-term placement of a pleural catheter provides effective palliation for malignant pleural effusion associated with trapped lung syndrome.

Minimally invasive investigations, such as pleural fluid cytological assessment and closed percutaneous pleural biopsy, are often performed first in the investigation of suspected malignant pleural effusions. Malignant pleural effusions can be diagnosed with pleural fluid cytology alone in most cases; however, closed pleural biopsy is performed to increase the diagnostic yield when pleural fluid cytology is negative. This additional yield is at the expense of increased complication rates. We report a 64-year old man with a negative pleural fluid cytology but suspected malignant pleural effusion who underwent a closed pleural biopsy, which was complicated by pneumothorax, pneumomediastinum and severe subcutaneous emphysema. Pulmonary laceration by the pleural biopsy needle is the most likely aetiology of these complications. Our case report highlights an infrequent but significant complication of closed percutaneous pleural biopsy.

Although general anesthesia still represents the standard when performing thoracic surgery, the interest toward alternative methods is increasing. These have evolved from the employ of just local or regional analgesia techniques in completely alert patients (awake thoracic surgery), to more complex protocols entailing conscious sedation and spontaneous ventilation. The main rationale of these methods is to prevent serious complications related to general anesthesia and selective ventilation, such as tracheobronchial injury, acute lung injury, and cardiovascular events. Trends toward shorter hospitalization and reduced overall costs have also been indicated in preliminary reports. Monitored anesthesia care in thoracic surgery can be successfully employed to manage diverse oncologic conditions, such as malignant pleural effusion, peripheral lung nodules, and mediastinal tumors. Main non-oncologic indications include pneumothorax, emphysema, pleural infections, and interstitial lung disease. Furthermore, as the familiarity with this surgical practice has increased, major operations are now being performed this way. Despite the absence of randomized controlled trials, there is preliminary evidence that monitored anesthesia care protocols in thoracic surgery may be beneficial in high-risk patients, with non-inferior efficacy when compared to standard operations under general anesthesia. Monitored anesthesia care in thoracic surgery should enter the armamentarium of modern thoracic surgeons, and adequate training should be scheduled in accredited residency programs.
