Thoracoscopic management of malignant pleural effusion: technique, complications and prevention.

In 1910, Professor H. C. Jacobaeus first described thoracoscopy. He used a modified cystoscope to inspect the pleural cavity. He described his two cannula techniques, one for the light source, and the other for viewing. Later on, the technique was improved, and a single cannula provided the light source and an optic telescope. With the advent of video assisted thoracoscopy, the procedure has gone full circle; once again, two cannulae are used - one to give us a video assisted telescopic picture and the second cannula is used for operational purposes.

[Surgery of lung metastasis].

INTRODUCTION: The 30-40% of the oncologic patients have pulmonary metastases. Lung can be the only organ affected. In selected patients, exeresis of the pulmonary nodules can mean their healing. MATERIAL AND METHODS: Between 1982-1997, twenty two patients presented metastases, 13 could be operated and 16 thoracotomies were done. There were 53% boys and 47% girls whose ages ranged from 3 to 15 years. We have considered: pulmonary tumour location, disease free interval, number of metastases, surgical technique and incomplete pulmonary tumour resection. RESULTS: Primary tumours were: Wilms tumours 23%, bone tumours 67% (Ewing and osteosarcoma). Disease free interval was < 2 years in 8 patients (61%) and > 2 years in 39%. X-Ray and CT were performed in every case and 66% presented a solitary nodule. Surgical techniques were: metastasectomy in two cases (12%), wedge resection in 8 (50%) and lobectomy in six cases (38%). We made thoracoscopy in two patients. There weren't postoperatory mortality but the patients with tumorectomy had an incomplete surgical resection. The overall survival is 54 percent and the 5 years survival is 23 percent (3 patients). CONCLUSIONS: The patients with a DFI < 2 years have a survival of 25% compared with 100% for patients who have a DFI > 2 years. The pulmonary resection in selected patients can offer better survival. We can use the thoracoscopy in same selected patients.

Malignant mesothelioma: experience at the Singapore General Hospital.

INTRODUCTION: Malignant mesothelioma is a rare occupational disease in Singapore. There have been few reports of this condition in Singapore. We aim to describe the clinical characteristics, management and outcomes in a case series of 16 patients diagnosed in a teaching hospital in Singapore. MATERIALS AND METHODS: A chart review of all cases of malignant mesothelioma diagnosed in our institution during the period 1996 to 2001 was conducted, with particular attention to the occupational history. RESULTS: There were 16 patients (15 male patients) with a median age of 61.5 (range, 46 to 78) years. Thirteen patients had malignant pleural mesothelioma (MPM) and 3 patients had mesothelioma of the periotoneum. Eleven of the patients with MPM (84.6%) presented with a pleural effusion and only 2 patients (15.4%) had chest pain. Initial pleural fluid cytology and closed pleural biopsies were negative in all patients who presented with a pleural effusion. Thoracoscopy confirmed the histologic diagnosis and allowed simultaneous talc pleurodesis in 9 patients. All patients had documented asbestos exposure, of which 14 (87.5%) were confirmed to be occupationally related. The median time from first exposure to symptoms was 33.5 (range, 16 to 53) years. The median survival was 6 months. Most of the patients (75%) received best supportive care alone. CONCLUSIONS: In our experience, malignant mesothelioma is an aggressive disease with a poor prognosis. It is strongly associated with asbestos exposure. Thoracoscopy is an invaluable diagnostic modality in the evaluation of a patient with occupational asbestos exposure and an undiagnosed pleural effusion.

[A case of catamenial pneumothorax due to diaphragmatic endometriosis confirmed by video-assisted thoracoscopic surgery].

We describe a case of catamenial pneumothorax caused by diaphragmatic endometriosis and histologically confirmed thoracoscopically. The patient was a 33-year-old woman who had had recurrent right chest pain starting on the day preceding each menstruation since she was 26 years of age. In June 2001, at the age of 33, she felt right chest pain and developed dyspnea, and so came to our hospital. Chest radiography showed bilateral pneumothorax. Timely thoracoscopy revealed the characteristic appearances of catamenial pneumothorax such as a blueberry spot on the central tendon of the right diaphragm and a purplish-red locus in the right apex. Histopathological examination further confirmed the presence of endometrial tissue on the diaphragm as well as in the lesion of the right lung. Despite resection of the endometrial tissues from the right hemidiaphragm and the lung under thoracoscopy, right pneumothorax recurred after one month. Since then, the patient's condition has been well controlled by therapy with gonadotropin releasing hormone, with no recurrence of catamenial pneumothorax.

[Benign pleural effusion caused by asbestos exposure].

The Authors present the first case described among us of benign pleural effusion of an asbestotic origin. They stress the importance of thoracoscopy (pleuroscopy) in the diagnosis of this situation. Attention is drawn to the fact that asbestotic lesions and asbestotic bodies have been found in the lung and, in particular, in the parietal pleura as well. They emphasize the fact that exposure to asbestos was not realized by the patient, which made the clarification of the situation more difficult. It was a CT scan that showed the signs suggestive of exposure to asbestos which raised the diagnostic suspicion. They conclude that every patient with a pleural effusion must be thoroughly questioned about exposure to asbestos. Even if the exposure is accepted, they consider that one should proceed to a pleuro-pulmonar biopsy by thoracoscopy. This biopsy allows demonstration of the characteristic histopathological lesions and rule out other etiologies, namely malignancy and tuberculosis. They suggest that these patients must be highly motivated to stop any smoking and kept under periodic surveillance.

Thoracoscopic excision of a paraesophageal bronchogenic cyst in a child.

BACKGROUND: Bronchogenic cysts are not uncommon in either children or adults. In children, they comprise approximately 6% of all mediastinal masses. Their presentation can range from an asymptomatic incidental finding to sudden respiratory distress. CASE REPORT: Video-assisted thoracoscopy was utilized to remove a bronchogenic cyst that was densely adherent to the adjacent esophagus in a child. This was accomplished with a Harmonic scalpel. The chest tube was removed on postoperative day 1, and the patient was discharged on postoperative day 2. An esophagogram obtained 2 weeks after surgery was normal, and the patient's preoperative symptoms had not returned. CONCLUSIONS: Bronchogenic cysts should be considered in the differential diagnoses for mediastinal masses at any age. Given their benign nature, thoracoscopy offers an excellent alternative to open thoracotomy for their removal.

[Video-assisted techniques in phthisiosurgery].

Ten years' experience in applying video-assisted techniques to surgery of pulmonary tuberculosis is generalized. For surgical diagnosis and treatment, a total of 465 patients underwent the following procedures: video-assisted thoracoscopy (n = 133), video-assisted open mini-invasive thoracotomies (n = 117), and mediastinoscopy (n = 215). The main indications for 250 video-assisted thoracoscopic operations were exudative pleuritis or pleural empyema, disseminated lesions to or round masses in the lung of unknown genesis, restrictive forms of pulmonary tuberculosis. After video-assisted thoracoscopic operations, complications were stated in 3.6% of cases; there were no deaths. The accumulated experience has shown that video-assisted thoracoscopy is of relatively limited utility. It is most effective in diagnosing pleuritis and disseminated lung lesions of unknown etiology. Video-assisted mini-invasive operations combine many advantages of open and endosurgical interventions. They may find more extensive use in the surgical treatment of different forms of pulmonary and pleural tuberculosis. In 215 patients, the indication for mediastinoscopy was intrathoracic lymph nodal abnormality of unknown genesis. Specimens for morphological studies were obtained in all cases, which promoted timely diagnosis and definition of treatment policy. Complications were observed in 1.4% of cases; no deaths were seen. Video-assisted mediasthinoscopy has been applied in the past 3 years. This endosurgical technique is technologically new, has a high resolution, and deserves wide use in thoracic surgery.

Percutaneous localization of pulmonary nodules prior to thoracoscopic surgery by CT-guided hook-wire.

BACKGROUND: When performing thoracoscopic surgery in patients with small pulmonary nodules, intraoperative localization can be difficult and time-consuming. The percutaneous localization of suspicious intrapulmonary lesions was evaluated pre-operatively to facilitate the resection of the lesion and to avoid thoracotomy. MATERIALS AND METHODS: Thoracoscopies were performed in 13 patients with intrapulmonary nodules previously localized by CT-scan and flagged percutaneously with a hook-wire. Immediately after the procedure, the patient was transferred to the operating room and thoracoscopic pulmonary wedge resection was performed. RESULTS: All the nodules were properly identified. The time to position the wire was 20-30 min and thoracotomy could be avoided in all patients. The nodules were 0.5 cm - 6 cm in size and situated 1 cm - 4 cm subpleurally. CONCLUSION: Guide-wire identification of an intrapulmonary nodule is a safe, elegant, time-saving and reliable method. The lack of manual examination of pulmonary parenchyma in thoracoscopy is compensated for by precise pre-operative localization.

Surgically removed thoracolithiasis: report of two cases.

Thoracolithiasis is a rare condition with only 12 cases of surgically removed nodules reported in the literature. We report 2 additional cases. Case 1: A 19-year-old male admitted with an abnormal shadow on a chest X-ray. Computed tomography (CT) revealed a nodule in the right lower lung lobe. The material extirpated by thoracoscopy was milky white, glossy, and 1.6 cm in diameter. Histopathologically, it consisted of fatty necrotic tissue covered with hyalinized fibrous tissue. Case 2: A 78-year-old female, with a past history of breast cancer, admitted with an abnormal shadow on chest X-ray. CT revealed a nodule in the left lung S(1+2) segment, of which transbronchial biopsy findings indicated primary lung adenocarcinoma. Exploratory thoracoscopy incidentally revealed some pearly material, 0.4 cm in diameter, in the thoracic cavity. They were extirpated during left upper lobectomy for lung cancer; all of them demonstrated concentric hyalinized fibrous tissue. Thoracic surgeons should consider this condition in the differential diagnosis of a peripheral pulmonary nodule.

[A predominant manifestation of pleural cryptococcosis in acquired immunodeficiency syndrome].

Systemic cryptococcosis occurs in at least 6% patients with human immunodeficiency virus infection (HIV). The lung infection by cryptococcus neoformans, less frequently observed than meningeal involvement, consists usually in focal parenchymal mycosis. Authors report an apparently isolated pleural cryptococcosis in a 41 years old mal with HIV infection. Diagnosis was performed initially by pleural and bronchial alveolar lavage (BAL) fluid culture. Characteristic cryptococcosis pathological and histologic findings from thoracoscopy and open pleural biopsy are described. Cryptococcus capsular polysaccharides stainings and thoracoscopy interests are emphasized.

[Diagnostic and therapeutic approaches to spontaneous pneumothorax].

Based on a retrospective study of 33 patients with spontaneous pneumothorax, the authors present their experience with the diagnostic and therapeutic procedure. In the majority of patients treatment was started by active suction drainage of the chest. After re-expansion of the lung another X-ray examination was made, incl. computed tomography of the chest, and endoscopic examination (bronchoscopy, thoracoscopy). On account of a relapse of pneumothorax in three patients thoracoscopy was performed and in seven patients thoracotomy. The operated patients recovered and are without signs of relapse of pneumothorax.

[Treatment of malignant mesothelioma using intrapleural gamma interferon].

8 consecutive patients with malignant diffuse pleural mesothelioma at stage IA were treated with recombinant gamma Interferon (RU. 42369 Roussel Uclaf) by the intrapleural route. Diagnosis was achieved by thoracoscopy. A solution of gamma Interferon (40 x 10(6) units) was infused twice a week for 6 hours over a period of 2 months via a catheter inserted in the pleural cavity. The principal side effect consisted of a "Flue syndrome" treated by Paracetamol. Evaluation of responses was based on a CT scan performed 2 weeks after the end of treatment; and on a repeat thoracoscopy with histopathological verification. In 6 patients we observed a complete histopathological response, lasting for 2 months in 1 patient. 1 patient was operated on after failure of Interferon treatment, 1 patient died 1 month after the end of the treatment; the death has not apparent connexion with the treatment.

[Applications and uses of pleurography in patients with spontaneous pneumothorax].

In a group of 74 patients, it proved possible by pleurography to localise bronchopleural fistulae, subpleural vesicles and interpleural adhesions. A comparison of the diagnostic procedures, pleurography, pulmonary CT scan and thoracoscopy, revealed that pleurography was best suited for the detection of bronchopleural fistulae, computed tomography was best in revealing subpleural or intrapulmonary vesicles, and thoracoscopy was best to demonstrate the presence of adhesions. In our patient material, the expanded diagnostic workup of spontaneous pneumothorax led to a substantial reduction in the so-called idiopathic pneumothorax from 53% to 26%. By preparing a differentiated therapeutic means, it was possible to appreciably reduce the recurrence rate of pneumothorax from 41% to 22%.

[Fibrin gluing in spontaneous pneumothorax].

The article reports on the results of surgical thoracoscopy using the mediastinoscope in relapsing spontaneous pneumothorax and persisting spontaneous pneumothorax. This surgical method is performed under intubation anesthesia. Existing changes such as emphysematous bullae or fused strands are removed or cut. The parenchymatous defects occurring after surgical removal of bullae are bonded by means of 2 ml fibrin adhesive. 75% of the patients treated in this manner remain free from recurrences so that it was not necessary to perform thoracotomy although this had been originally indicated. Measures for pleurodesis that are not "on target" must be rejected, since they do not help in removing the morphological changes at the lung surface. Surgical thoracoscopy as described is, therefore, in some cases an alternative to classical thoracotomy.

[Efficient diagnosis of pleural effusion].

Under physiological conditions the pleural cavities contain a few millilitres of a fluid film with a protein content of about 1.7 g%. Because of the different capillary pressure, there is a regular flow of fluid from the parietal pleura to the visceral pleura. In cases of increased hydrostatic pressure or reduced colloid osmotic pressure in the absence of pleural disease, transudation takes place; in disturbances of permeability resulting from various types of inflammation, neoplasms or vascular disorders, and in disturbances of lymph backflow, exudates are formed. A pleural effusion is easily recognizable in typical cases. Reference is made to particular radiological manifestations which are not always correctly interpreted, viz. subpulmonary effusion, encapsulated interlobar effusion ("vanishing tumour") and predominantly mediastinal effusion. Precise examination of the neighbouring organs, together with thoracentesis and pleural biopsy, are decisive for the etiological diagnosis. When examining the effusion, it is of great importance to differentiate between transudate and exudate. Light's definition of transudate proved to be valid in this study (protein content below 3 g% and LDH index below 0.6). For the basic examination, we further recommend cytology and--to save time--tuberculosis bacteriology as well. The significance, sensitivity and specificity of various other chemical tests are discussed. For diagnostic strategy it is always necessary to take into consideration the entire clinical situation, including radiology and laboratory tests. With this proviso, a specific investigation scheme may be recommended. After application of the usual diagnostic methods, including pleural biopsy, aetiologically unclear effusions remain in about 20-25% of cases. Approximately 2/3 of these can be diagnosed by means of optimized biopsy technique under thoracoscopy and are predominantly tumoral effusions. Approximately 1/3 (5-10% of the total number) still remain unclear as "idiopathic" effusions, even after thoracoscopy. The relative importance of early diagnosis of a malignant pleural effusion is discussed.

A survey of South African endoscopic surgical practice.

To coincide with the first annual meeting of the South African Society of Endoscopic Surgeons (SASES), a postal survey of the endoscopic surgical practices of 98 registered specialist surgeons was undertaken. A response rate of 73.5% was achieved, and 94.5% of respondents had personally performed endoscopic surgical procedures. Cholecystectomy (4,557) was the most commonly performed endoscopic surgical procedure and was associated with a postoperative mortality rate of 0.13% and morbidity of 3.5%. Twelve bile duct injuries were reported (0.26%). In descending order of frequency, other procedures reported were diagnostic laparoscopy (1,404), dorsal sympathectomy (412), appendicectomy (396), inguinal hernia repair (146), anti-reflux procedures (83) and diagnostic thoracoscopy (51). No postoperative deaths were recorded and complication rates varied from zero for diagnostic thoracoscopy to 4.8% for inguinal hernia repair and anti-reflux procedures. The selected sample of South African surgeons canvassed appears to have adopted endoscopic surgical techniques with enthusiasm and with complication rates that compare favourably with those reported elsewhere.

Thoracotomy, critical pathway, and clinical outcomes.

Using a multidisciplinary critical pathway for chest surgery, the staff of Saint Joseph Medical Center (Burbank, California) and its physicians developed a strategy leading to improved patient outcomes with reduced overall costs. On referral from the surgeon's office, the multidisciplinary team, consisting of a clinical nurse specialist, physical therapist, and respiratory therapist, meet with the patient. The education that follows includes discussion of the surgical procedure, intubation, incentive spirometry, coughing, deep breathing, early ambulation, use of patient-controlled analgesia, chest physiotherapy, transfusion options, and evaluation of health status. A few days later, the patient undergoes the thoracoscopy-assisted thoracotomy. The success of the outcome-driven critical pathway can be related to several factors: (1) close coordination between the surgeon's office and hospital; (2) intensive preoperative education that decreases patient's anxiety and increases his or her ability to participate in recovery; (3) patient-controlled analgesia, nerve blocks, non-narcotic analgesia, and preemptive rehabilitation, which limit the risk for complication; and (4) thoracoscopy, which limits the surgical morbidity commonly affiliated with thoracotomy. The pathway, used for 160 patients during the past 2 years, has shown dramatic results related to reducing morbidity, practice variation, delay, and total overall cost.

[Thoracoscopic therapy of iatrogenic hemothorax].

Video-assisted thoracoscopy is an innovative technique which now allows the surgeon to approach various intrathoracic pathologic conditions without thoracotomy. In a 20-year-old male with pneumothorax urgent surgical intervention was necessary because of severe hemothorax following chest tube placement. The successful management of this patient by video-assisted thoracoscopy is presented.
