Abstract
STUDY OBJECTIVES To evaluate Vivostat fibrin sealant in the prevention of air leakage after experimental lung resection in pigs. DESIGN Randomized study. SETTING University laboratory. METHODS Six Landrace pigs were operated on in both lungs through a median sternotomy. Five different resection sites were created in each lung. INTERVENTION Randomization was performed to either application of Vivostat fibrin sealant (ConvaTec; Skillman NJ) or human albumin 20% (control) at the resection sites. The lung parenchyma was occluded with a soft clamp for either 1, 2, 5, or 10 min in the treatment group and 10 min in the control group. After removal of the clamp, the lung was ventilated with an increasing intrabronchial pressure of 20, 30, and 45 cm H(2)O for 2 min at each step. RESULTS At inspiratory pressures of 20 and 30 cm H(2)O air leaks were found in the control group but not in the Vivostat group (p < 0.001). At an inspiratory pressure of 45 cm H(2)O, there were two small air leaks in the Vivostat group at each clamping time (four at 5 min), compared with five small and seven large leaks in the control group. Analysis of the data after 10 min of clamping showed that the Vivostat group was superior to the human albumin group (p = 0.002). CONCLUSIONS This randomized study shows that Vivostat fibrin sealant is effective in preventing air leakage after small lung resections in pigs, even at high inspiratory pressures.

Abstract
OBJECTIVE To evaluate the outcomes from a new surgical technique for lobectomy. PATIENTS Two hundred fifty consecutive patients with an average age of 67.3 years underwent simultaneously stapled lobectomy. METHODS Video-assisted thoracic surgical non-rib spreading lobectomy (VNSSL) is a new technique that has been evolving for approximately 6.5 years. During 1990, we began using video-assisted thoracic surgery (VATS) for simple, benign diseases. Throughout 1991, VATS was applied to malignant problems, ie, mediastinal masses, staging of lymph nodes, malignant effusions, and coin lesions. As experience was acquired, more complex procedures were attempted, such as lobectomy. On September 9, 1991, our first VATS lobectomy, using anatomic hilar dissection and lymph node sampling, was performed for primary carcinoma of the lung. One year later, we performed our first VNSSL using simultaneous stapling. RESULTS Currently, 400 VNSSLs have been performed. In this entire series, there have been no surgical mortality, bronchopleural fistulas, port implantations, or transfusions. Bronchial stumps have averaged 4 mm in length, and all have been microscopically negative for neoplasm. In order to evaluate long-term survival for primary carcinoma of the lung in patients with an adequate duration of follow-up, the first 250 consecutive VNSSLs have been reviewed. There were 120 male and 130 female patients ranging in age from 20 to 92 years old who had 62 right upper lobe, 20 right middle lobe, 58 right lower lobe, 63 left upper lobe, and 33 left lower lobe lobectomies, and 14 bilobectomies. The lesions consisted of 214 primary carcinomas, 8 metastatic lesions, and 28 benign problems. Seven to 18 lymph nodes could be resected during staging of the primary neoplasms. The tumors ranged in size from 1 to 9 cm, and operating times averaged 78.6 min. Hospitalization averaged 2.83 days. No patient was admitted to the ICU. Intensive monitoring or narcotic analgesia were not needed. No epidural or intercostal anesthesia was used. Complications were infrequent and minor. Most patients returned to preoperative levels of physical activity within 7 to 10 days. Overall survival at a mean of 34 months, when all stages of neoplasms were combined, is 83%. For stage I, overall survival is 92%. The cost of VNSSL is approximately 50% less than the traditional open thoracotomy. CONCLUSIONS VNSSL is an oncologic technique that has been clinically rewarding and economically beneficial for patients with malignant lesions. Long-term survival for primary carcinoma currently exceeds reports being published for the traditional open thoracotomy. Scientific reasons for this extraordinary survival are emerging. Complications, surgical mortality, pain, and length of stay have all been reduced. Patient recovery, comfort, and satisfaction have been extraordinary.

Abstract
A 56-year-old male diagnosed of epidermoid carcinoma of the right lung (T4 N0 M0, stage IIIb) is described. He had earlier received chemotherapy and radiotherapy and was scheduled for removal of the right lung. During surgery the need to resect tumor infiltration of the right atrium became evident. During weaning from by-pass sudden deterioration of hemodynamics occurred with poor response to volume and inotropic drugs. Superior vena cava syndrome due to traction of the innominate trunk from a surgical retractor was diagnosed; the crisis resolved when the retractor was withdrawn. We discuss the pathophysiology of this clinical picture and relevant intraoperative aspects.

Abstract
BACKGROUND Improvements in surgical equipment have rendered video-assisted thoracic surgery (VATS) an effective device for thoracic surgeons and nowadays several intrathoracic diseases can benefit from this approach. This development has expanded potential use and recently the technical feasibility of major lung resections by VATS has been demonstrated. The authors present their experience with a standard muscle-sparing utility thoracotomy (UT) utilized for all VATS procedures, including major lung resections. METHODS From November 1996 to October 1997, 30 patients were operated on. There were 22 males and 8 females (medium age 58 years; range 24-78). There were 13 anatomical lung resections (i.e.: 11 lobectomies, 1 left pneumonectomy, 1 segmental resection), 8 wedge resections, 3 lung biopsies, 2 debridements of pleural empyema, 2 mediastinal nodes biopsies, 1 esophageal resection for leiomyoma, 1 excision of benign mediastinal cyst. RESULTS No mortality or major morbidity were recorded, as well as no rib fractures due to the rib spreader. Two patients suffered from prolonged air-leaks after respectively left upper lobectomy and lung biopsy and required prolonged chest drainage. Concerning anatomic major lung resections the medium hospital stay was 7.9 days and medium chest tube time was 5.6 days. The utility thoracotomy through the auscultatory triangle proved to be a safe approach and confirmed the technical feasibility of various type of surgical procedures with results comparable to standard open thoracotomy. Our data shows that VATS approach did not seriously affect the duration of hospital stay, chest tube time, the overall morbidity or lung function. CONCLUSIONS As the real benefit of this approach remains controversial, the majority of the studies comparing the VATS approach to conventional muscle-sparing thoracotomy neither nor prospective nor randomized, and several parameters are difficult to evaluate in the literature further study are mandatory.

Abstract
OBJECTIVE To review the literature on the surgical treatment of emphysema and to present preliminary results from a pilot study of lung volume reduction (LVR) surgery. DESIGN Case series of consecutive patients referred for LVR surgery. Outcomes were quality of life, pulmonary function and exercise capacity. SETTING Two university-affiliated hospitals in Ontario. POPULATION STUDIED Patients between the ages of 40 and 75 years with emphysema who had severe airflow limitation, hyperinflation of the lungs and impaired quality of life. INTERVENTION Bilateral reductions with multiple wedge resections of the lung using a linear stapling device with bovine pericardial buttressing were completed via a median sternotomy. MAIN RESULTS Of 50 patients referred, 24 underwent LVR surgery. Mean age of the cohort was 63 years. Operative 30-day or in hospital mortality was 8%. Two other patients (8%) died from respiratory failure after LVR within the first year. Postoperative complications included prolonged air leaks (six of 24), tracheobronchitis (five of 24), mechanical ventilation (four of 24) and pneumonia (three of 24). Mean length of stay was 18 days (median 12 days). At one year, there was a sustained decrease in total lung capacity from 133% to 123% predicted. There were improvements in forced expiratory volume in 1 s, from 22% of predicted preoperatively to 32% postoperatively, and in 6 min walk performance, from 345 to 381 m. Improvements were also noted in the quality of life assessments. CONCLUSIONS Preliminary results suggest that LVR surgery is feasible and may improve the patient's quality of life, pulmonary function and exercise capacity. A randomized clinical trial comparing LVR plus the best medical management with the best medical management alone is currently underway to determine the effectiveness of LVR.

Abstract
VATS is able to perform by minimal access all operations known in general thoracic surgery. Mortality (0.07-1.9%) is low and complications (4.3-14.2%) are rare, as published in four studies in the last two years. Especially long-term results of VATS in malignant disease are not clear. Indications and limitations for VATS in bronchial carcinoma and lung metastases are discussed. Surgical treatment in peripheral non-small cell lung cancer has best results after lobectomy. Limited resection decreases the oncological result (5-year-survival-rate) by 10 to 18% compared to lobectomy. Conservative treatment with radiotherapy in stage I carcinomas in patients who are not eligible for open lobectomy because of restricted lung function or other non oncological reasons has a bad prognosis (0-12% 5-y-survival). In these cases VATS resection of bronchial carcinoma should by considered. Detection of all lung metastases by preoperative radiological study is only in 56-75% possible. Between 10/93-2/98 we performed 52 thoracotomies for lung metastases at our surgical department. In eight cases bronchial carcinoma was confirmed by histological examination, nine patients with metastases of malignant germ-cell-tumors were excluded from the study. CT-scan of the lung was performed preoperatively. In 43% of the cases (n = 35) additional lesions were detected intraoperatively by palpation of the lungs. Histopathologic examination revealed benign lesions in 9% and malignant in 34%. The result of lung metastases resection is highly dependent on the completness of extirpation. We therefore conclude that lung metastases should be removed by open thoracotomy.

Abstract
INTRODUCTION The purpose of this study was to evaluate the impact of thoracoscopy on staging and therapy of peripheral pulmonary nodules in patients with a cancer history. PATIENTS AND METHODS Videothoracoscopy (VATS) was performed in patients presenting peripheral pulmonary nodules (< 3cm) in CT-scan. 65 patients (63%) presented less than 3 nodules and 39 patients (37%) had multiple lesions in the lungs. History revealed a primary gastro-intestinal cancer in 35 patients (34%), a sarcoma in 26 patients (25%), breast cancer in 13 patients (13%) and miscellaneous primary cancer in 22 patients (21%). VATS was performed under general anesthesia using a standard equipment (Olympus). Double lumen endotracheal intubation was carried out. Thoracoscopic pulmonary resection was accomplished with endoscopic stapler (Autosuture Multi-Fire Endo GIA 30). The specimens were removed in a retrieval bag and a tube was inserted into the thoracic cavity. RESULTS In 24 patients (23%) conversion to thoracotomy was performed, because of adhesions (n = 12), technical reasons (n = 8), no tumor detectable (n = 4). Thoracoscopic wedge resection for coin lesions was performed in 61 of the 80 patients (76%). Three patients underwent decortication and in 16 patients biopsy was sufficient for therapeutical considerations. Additional informations in comparison to conventional diagnostic were found in 39 patients (49%). The treatment regimen altered in 32 patients (40%). CONCLUSIONS In this study VATS proved to be a sensitive technique for staging of pulmonary coin lesions. Additional informations were achieved in 49% and therapeutic strategy was changed in 40% of the patients due to the distant spread of malignancy or detection of benign lesions obtained by thoracoscopic staging.

Abstract
The morbidity and mortality for video-assisted curative resection of lung cancer was evaluated retrospectively. Forty-one consecutive patients with stage I and II lung cancer underwent video-assisted curative lobectomy with complete hilar and mediastinal lymphadenectomy. Conversion to an open procedure was necessary in two patients. The operating times for the second half of the series were shorter than for the first half. Compared with patients receiving a standard open procedure, the video-assisted patients experienced satisfactory results. We conclude that video-assisted curative lobectomy with complete lymphadenectomy for stage I and II lung cancer is technically feasible in the majority of patients, although follow-up is required to determine the long-term prognosis. Comparative series between video-assisted and open procedures should not be conducted until the surgeon has acquired the necessary video-assisted skills. A prospective randomized trial will determine the actual value of video-assisted procedure for lung cancer treatment.

Abstract
In order to prevent the local recurrence of malignant tumors, it is important for surgeon to maintain a sufficient margin between the tumor and the edge at resection. For this reason we do not use an auto-suturing device, but instead use the ultrasonic cutting and coagulating system (HARMONIC SCALPEL, ETHICON ENDO-SURGERY Cincinnati, Ohio) whenever we perform either a segmental resection or a wedge resection of the lung. The subjects investigated consisted of 24 cases of lung tumors (15 metastatic tumors, 5 cases with primary lung cancer, 3 inflammatory tumors; and one benign tumor). The type of operation included 10 segmental resections and 14 wedge resections, with 21 open thoracotomies and 3 instances of thoracoscopic surgery, while 15 were single resections and 9 were multiple resections. Little bleeding was seen at the resection of the parenchyma and the vessels of the lung. However prolonged air leakage was observed in some cases that needed pleurodesis. The mean duration time of the surgery was 266 minutes, and the mean blood loss was 173 ml. The operative duration was a little longer than normal, because many cases were not first thoracotomies and some cases had multiple tumors. Nevertheless the amount of blood loss was slight. The longest post-operative period was two years and six months, no local recurrence has yet been seen in any of malignant cases. We consider this system to be very effective for performing a resection of the lung parenchyma because of the reduced blood loss and the apparent increased prevention of recurrence.

Abstract
Lung volume reduction surgery (LVRS) improves dyspnoea and pulmonary function in selected patients with severe emphysema. The purpose of this study was to assess the effects of LVRS on exercise performance and gas exchange in relation to changes in pulmonary function. In 40 patients (63.2+/-1.4 yrs, mean+/-SE) with severe emphysema (forced expiratory volume in one second (FEV1) 29+/-1% predicted, residual volume/total lung capacity (RV/TLC) ratio: 0.63+/-0.01) we assessed dyspnoea, pulmonary function and exercise performance before and 3 months after bilateral video-assisted thoracoscopic LVRS. The Medical Research Council dyspnoea score fell from 3.5+/-0.1 to 1.4+/-0.1 (p<0.0005); FEV1 increased by 55+/-9% to 44+/-2% pred (p<0.0005), RV/TLC decreased from 0.63+/-0.01 to 0.51+/-0.02 (p<0.0005). The diffusing capacity remained unchanged. Maximal work load during bicycle ergometry increased from 34.3+/-2.0 to 48.9+/-2.4 W (p< 0.0005), maximal oxygen uptake (V'O2max) from 10.0+/-0.4 to 12.8+/-0.3 mL x kg(-1) x min(-1) (p<0.0005). The increase in maximal ventilation during exercise (V'Emax) from 29.5+/-1.5 to 38.6+/-1.8 L x min(-1) (p<0.0005) was associated with increases in tidal volumes at isowatt and maximal exercise while corresponding breathing frequencies remained unaltered. The increases in V'O2max and V'Emax correlated with the increases in FEV1 and the decreases in RV/TLC. We conclude that the improvement in pulmonary hyperinflation and airflow obstruction after bilateral thoracoscopic lung volume reduction surgery may reduce ventilatory limitation, thereby increasing exercise capacity.

Abstract
In a prospective study, we investigated the functional results, complications, and survival of patients who underwent bilateral video-assisted thoracoscopic (VAT) lung volume reduction surgery (VRS) for severe, diffuse pulmonary emphysema (FEV1 0.77 +/- 0.03 [1], RV/TLC 0.65, 12' walking distance 482 +/- 26 [m]). From January 94 to March 97, 67 of 179 candidates underwent the operation, and 58 patients (mean age 64 +/- 1.1, range 42-78 years; 17 women) fulfilled the study criteria. There was no 30-day mortality; hyperinflation decreased to an RV/TLC ratio of 0.52 +/- 0.01 after 3 months; FEV1 increased to 1.2 +/- 0.08 [1]; and the 12' walking distance was 687 +/- 29 [m].

Abstract
BACKGROUND Lung volume reduction surgery either via sternotomy or by thoracoscopy has been demonstrated to be effective for selected emphysema patients in North America and Europe. The present study summarizes short-term results of bilateral lung volume reduction performed via median sternotomy for the first consecutive 39 patients with severe diffuse emphysema in Okayama, Japan, from July 1995 to February 1997. METHODS There were 35 men and 4 women, and the age range was 54 to 74 years with a mean age of 65 years. All were former heavy smokers and none of them had alpha1-antitrypsin deficiency. Only 9 patients (23%) showed a bilateral upper lobe pattern of emphysema. The operation was done through a median sternotomy, and the most emphysematous portions were excised bilaterally with a linear stapling device fitted with strips of bovine pericardium to prevent air leakage. RESULTS No operative death was encountered. The first 33 patients completed 3-month follow-up assessment, and their mean forced expiratory volume in 1 second had improved by 41% from 735 mL to 1,037 mL. Other parameters of pulmonary function tests, arterial blood gas analysis, 6-minute walking distance, and dyspnea scale also had improved significantly. These improvements lasted for at least a year. CONCLUSIONS Bilateral lung volume reduction surgery via median sternotomy is a safe and effective procedure for selected severe emphysema patients. Although the pattern of emphysema might be different between countries, the results in Japanese patients were similar to those previously reported in North American and European patients.

Abstract
A new technique for pulmonary lobectomy has been utilized for malignant lesions. Eighty-five consecutive patients with pulmonary neoplasms underwent a VATS non-rib spread Simultaneously Stapled Lobectomy. There were 34 males and 51 females with 61 adeno, 21 squamous, 2 large cell and 1 carcinoid tumor who underwent 18 left upper, 13 left lower, 20 right upper, 7 right middle and 27 right lower lobectomies. Forty-one mediastinoscopies were negative. Patients with positive mediastinoscopies were not selected for curative resection. At VATS exploration, 10 patients had positive nodes. All resected nodes were negative in the other patients. Every bronchoscopy was negative. Operating times averaged 84.5 minutes. No patient received a transfusion. Lesions ranged from 1 cm to 8 cms with an average size of 3.62 cms. Post-operative length of stay averaged 3.38 days. There was no surgical mortality, no hemorrhage, no transfusion and no conversion to an open case in the entire series. No bronchial, vascular or broncho vascular fistula occurred. Complications were minor from which all patients recovered completely. Survival seems similar to patients resected by traditional open techniques.

Abstract
We employed wedge resection using stapling device for peripheral, clinical stage I lung carcinoma in selected poor-risk patients. Out of 10 patients, four developed local recurrence and one had the second primary in the same lobe resected. Compared with patients having lobectomy with 91% of a recurrence free rate in three years, those who underwent wedge resection had the lower rate of 53%. We conclude that wedge resection using stapling device cannot be an acceptable procedure even for poor-risk patients.

Abstract
BACKGROUND Lung volume reduction surgery (LVRS) using a linear cutting stapler or laser ablation via median sternotomy or thoracoscopy is a current therapy for symptomatic emphysema. The primary causes of morbidity and mortality (as high as 20%) are existing comorbidities and prolonged air leaks secondary to visceral pleural division. We report a novel technique using minimally invasive techniques designed to achieve volume reduction while preserving the visceral pleura. A novel lung grasper and a knifeless stapler are used to permanently plicate lung tissue without cutting visceral pleura. STUDY DESIGN This prospective analysis involves a consecutive series of patients who had LVRS using this method. Between May 1995 and September 1996, 32 patients underwent 50 unilateral, staged bilateral, or bilateral thoracoscopic lung plication procedures. The indications for LVRS were standard; they included severe limiting dyspnea (forced expiratory volume in one second [FEV1] = 0.68 +/- 0.05), hyperinflated lungs with flattened diaphragms on chest x-ray, and diffuse emphysema seen on chest computed tomography scan. Ventilation and perfusion scanning was used to identify potential ventilation and perfusion mismatch target areas of lung for plication. RESULTS The right lung was plicated first in 25 of 32 patients (78%), and upper lobe plications predominated (77%). A mean of 9.3 +/- 0.8 staple firings were used for each unilateral plication procedure. There were no perioperative deaths. Two patients (4%) required axillary thoracotomies to repair air leaks. Mean chest tube duration was 6.3 +/- 0.5 days. Median hospital stay was 7 days (range 3-15). An Intensive Care Unit stay was required following 8 procedures (17%). Postoperative morbidity occurred in 18 (39%) of 46 procedures, including 5 cases of atrial fibrillation and 4 persistent (> 7 days) air leaks. A minimum 2 month followup was available for 22 patients (32 of 46 procedures), demonstrating a clear chest x-ray with significant improvement in ipsilateral diaphragmatic contour. Twelve patients had unilateral reduction, and 10 patients had bilateral reduction in either a staged (n = 7) or sequential at one operation (n = 3) fashion. Twenty-five (78%) of 32 procedures were associated with improved pulmonary function, with a mean increase in FEV1, in patients in this subgroup of procedures, of 43 +/- 7% for each ipsilateral plication at a mean followup of 3.8 +/- 0.5 months. For the entire group of 32 procedures, the mean improvement in measured FEV1 was 29 +/- 7%. Supplemental oxygen requirement was significantly reduced in 9 of 16 patients following plication. CONCLUSION These data suggest that minimally invasive surgical techniques coupled with a no-cut lung plication can achieve significant lung volume reduction with favorable postoperative morbidity and mortality. Lung plication appears to hold promise as an alternative technique of LVRS.

Abstract
A lung carcinoma with tumor involving more than one lobe or in close proximity to the mainstem bronchus often requires pneumonectomy for surgical cure. Inflammation, bulky tumors, and dense adhesions limit the operative field of vision and may result in the abandonment of procedures with potential for complete extirpation. This case illustrates the utility of thoracoscopy in visualization of the hilum and other neurovascular structures in a patient with a proximal tumor and dense intrathoracic adhesions. Successful resection was made possible by use of combined open and thoracoscopic modalities.

Abstract
A 45-year-old man with bronchial carcinoid arising from the subsegmental middle-lobe bronchus was treated by video-assisted thoracic surgery. Lobectomy with mediastinal and hilar lymph node sampling was successfully performed in this patient. To obtain a tumor-free surgical margin on the middle-lobe bronchus, the interlobar pulmonary artery was retracted posteriorly, the middle-lobe bronchus anteriorly. The bronchus was then stapled and transected.

Abstract
We performed thoracoscopic lung resection seven times in four patients with lung metastases from colorectal cancer. This procedure allowed a short operation time, minimal blood loss, and a short hospital stay. Thoracoscopic lung resection was chosen for resection of lung metastases from colorectal cancer because it allowed simultaneous bilateral lung resection and early postoperative adjuvant chemotherapy.

Abstract
Technical advances in the field of endoscopical surgery have widened the spectrum of thoracoscopic operations in the therapy of lung emphysema. Especially in patients who are severely disabled as a result of their reduced lung function, a less surgical trauma should result in better postoperative performance. Bullectomy, which was an integral part of the spectrum in thoracic surgery for a long time, should be performed in a minimally invasive way today. In the American literature, disappointing results have been published concerning laser resection of emphysematous lung tissue. As a result, this method should be abandoned. In contrast, lung volume reduction surgery in patients with diffuse emphysema has caused significant improvement in lung function. The initial approach to this method was a median sternotomy. However, recent experiences in several centers have demonstrated the feasibility and efficiency of a thoracoscopic procedure.

Abstract
Airway control and protection, in any operation, is the first priority. The presence of a T-Y stent in the proximal airway can complicate this fundamental principle. Here we describe an effective and safe technique for positive-pressure single-lung ventilation via a T-Y stent for a lung lobectomy.

Abstract
Minimally invasive thoracoscopic staging for lung cancer was compared with re-staging by open thoracotomy in seventeen patients to evaluate whether videoimaged thoracoscopic staging was accurate. Seventeen patients underwent thoracoscopic staging initially with a closed videoimaged technique. These same patients then underwent an open thoracotomy and re-staging with a therapeutic resection for lung cancer. All patients underwent pleural evaluation and biopsy if indicated, thoracic hilar and mediastinal lymph node sampling, and then resection of the parenchymal lesion via a wedge resection, lobectomy or pneumonectomy. There was complete TMN stage correlation between the closed videoimaged thoracoscopic and open thoracotomy techniques. This preliminary study suggests minimally invasive videoimaged thoracoscopic staging is an accurate method to assess the stage of lung cancer to guide rational management.

Abstract
BACKGROUND Thoracoscopic-assisted pulmonary resection for lung cancer is controversial. The appropriateness of this approach has to be compared with the golden standard of an open resection. METHODS This study consists of 66 patients with a clinical stage 1 disease. A thoracoscopic exploration was executed in 41 patients. Only in 16 cases was a thoracoscopic resection finally possible. The clinical and pathological TNM classification, the histological types and the surgical procedure are reported. The reasons for conversion are documented. RESULTS To investigate the appropriateness of the thoracoscopic approach we evaluated only the pathologically proven stage 1 disease in both groups. Postoperative complications, hospital stay and survival are compared. CONCLUSION Until now we can conclude that there is no adverse effect on survival because of the thoracoscopic approach.
