Abstract
Provision of anesthesia care to patients undergoing thoracoscopic procedures, especially video-assisted thoracoscopy, requires thorough knowledge of the sur gical procedure and the physiology of one-lung ventila tion, as well as meticulous attention to detail by the anesthesia personnel caring for these patients. Thoracos copy is used increasingly to perform almost the entire range of thoracic surgical procedures in a minimally invasive fashion. Excellent quality anesthetic care is necessary to assure the benefits of minimally invasive surgery to the maximum number of patients undergo ing thoracic surgery. This article will provide anesthesi ologists caring for patients undergoing thoracoscopy with the necessary working knowledge of the technical aspects of the procedure and understanding of the relevant anesthetic implications. Preoperative, intraop erative, and postoperative concerns will be addressed. The scope of this article will be limited to noncardiac uses of thoracoscopy.

Abstract
Patients with impaired pulmonary function are at increased risk for the development of postoperative complications. Recently exercise testing and predicted postoperative (ppo) function have gained increasing importance in the evaluation of lung resection candidates. We prospectively evaluated an algorithm for the preoperative functional evaluation that was developed at our institution. This algorithm incorporated the cardiac history including an electrocardiogram (ECG), and the three parameters FEV1, diffusing capacity of the lungs for carbon monoxide (DLCO), and maximal oxygen uptake (VO2max), as well as their respective ppo values (FEV1-ppo, DLCO-ppo, and VO2max-ppo) calculated based on radionuclide perfusion scans. A consecutive group of 137 patients (mean age 62 yr; range 23 to 81; 102 males, 35 females) with clinically resectable lesions underwent assessment according to our algorithm. Five patients were deemed functionally inoperable, 132 passed the algorithm and underwent pulmonary resections with standard thoracotomy: 9 segmental or wedge resections, 85 lobectomies (inclusive 3 bilobectomies), and 38 pneumonectomies. All patients were extubated within 24 h. The mean stay in the ICU was 1.4 (+/- 1.8) d, and the mean hospital stay was 14.6 (+/- 5) d. Postoperative complications (within 30 d) occurred in 15 patients (11%), of whom two died (overall mortality rate 1.5%). In comparison to our previous series this meant a 50% reduction in complications whereas the percentage of inoperable patients remained unchanged (4% now, 5% before). We conclude that adherence to our algorithm resulted in a very low complication rate (morbidity and mortality), and excluded more rigorous patient selection as a bias for the improved results.

Abstract
BACKGROUND This study was performed to evaluate the technical feasability and validity of video-assisted pulmonary lobectomy using simultaneous stapling of the hilar structures. METHODS Between December 1995 and July 1997, 30 video-assisted thoracic non-rib spread simultaneously stapled lobectomies (VATS(n)SSL) were performed. RESULTS Fourteen males and 16 females underwent 9 right upper, 4 right middle, 5 right lower, 4 left upper, and 8 left lower lobectomies for 15 adenocarcinomas, 7 squamous cell carcinomas, 4 benign and 2 metastatic lesions, 1 carcinoid and 1 mucosa-associated lymphoid tissue-lymphoma. All patients with primary lung carcinoma had peripheral lesions, 13 were T1 and 9 were T2 lesions. Lesions ranged from 1.0 cm to 4.0 cm, averaging 2.2 cm. Results of 10 cervical mediastinoscopies were negative. Two patients had positive nodes at postoperative examination. Operating time for the series averaged 128 minutes, for the first 10 patients 146 minutes, and for the last 10 patients 106 minutes. There was no surgical mortality and no transfusion. Perioperative bleeding averaged 185 mL. Two procedures were converted to open thoracotomy. Hospitalization averaged 4.4 days for the entire group. CONCLUSION Video-assisted thoracic surgical non-rib spread simultaneously stapled lobectomy is a technically feasible and safe procedure. Therapeutic outcomes for resected neoplasms need to be evaluated in long-term follow-up studies.

Abstract
The application of video-assisted thoracic surgery (VATS) for major lung resection is controversial. We review our combined experience from three centers in Asia. From June 1993 through June 1997, 214 patients underwent VATS major resections (2 segmentectomies, 203 lobectomies, 6 bilobectomies, 3 pneumonectomies), mostly for primary malignancy. Stringent selection criteria were used to choose patients for this approach. We prefer a technique of not spreading ribs, using conventional thoracic instrument for dissection and routine use of wound protector for specimen retrieval. There was one postoperative surgical death and 47 non-fatal complications, which compare favorably with published series on open technique. Of the primary lung cancer patients, 93% are still alive after a mean follow-up of 26 months. We conclude that VATS major lung resection is technically feasible in selected patients and associated with favorable intermediate-term results.

Abstract
One hundred fifty video-assisted thoracic surgery (VATS) endoscopic hilar dissection lobectomy procedures are presented. Median blood loss was 65 mL and correlated with operative time (P < .0001) which averaged 144 minutes. Conversion to open thoracotomy was required in a further 20 patients (11.8%). One VATS patient (0.67%) died at 4 days from a catastrophic pulmonary embolus and 2 patients died within 30 days of surgery from pulmonary embolism and adrenal failure (overall 30-day mortality, 2%). Serious complications occurred in 3 cases: bronchopleural fistula (1) and requirement for ventilation (2). Air leakage (>4 days) occurred in 17 patients, correlated (P < .0003) with the presence of either adhesions or fissural fusion (11.3%), and resulted in prolonged hospitalization compared with patients without air leakage (11.1 vs 6.7 days; P < .0004). Open thoracotomy patients required 42% more morphine (P < .001) and 25% more nerve blocks than VATS patients (P < .001) who were 33% more likely to sleep following surgery (P < 0.01). Follow-up of 97 patients with non-small cell lung cancer (2,634 months total: mean 27) revealed 14 recurrences: 10 systemic and 4 (28.6%) within the thorax. No port site or pleural recurrences occurred. Stage analysis showed survival free of lung cancer-related death of 94% at 36 months for Stage I, 57% for Stage II, and 25% for Stage III.

Abstract
Videoendoscopic lobectomies or pneumonectomies are infrequently performed, mostly because of technical difficulties, concern for intraoperative accidents, and radicality in case of malignancy. The work diffusely describes technical details and a personal experience of videothoracoscopic major pulmonary resections (MPRs). All patients are first explored thoracoscopically. The procedure can then be completed thoracoscopically or converted. Videothoracoscopic exploration was performed in 211 candidates to MPR. Six patients' cases became nonresectable owing to pleural carcinomatosis or mediastinal infiltration, 171 patients completed a thoracoscopic MPR (165 lobectomies and 6 pneumonectomies), and 34 required conversion for technical (20) or oncological (10) reasons. Video MPRs were performed for benign disease (24), for lung metastases (5) and for preoperatively staged T1N0 or T2N0 primary lung cancer (142). No perioperative mortality was recorded. In 154 patients (90%), postoperative course was uneventful. One patient died after 33 days because of contralateral pneumonia; 15 elderly patients had prolonged air leaks. One patient developed partial dehiscence of the bronchial stump (healed conservatively) after a severe respiratory insufficiency on his third postoperative day had required mechanical ventilation. Even though video MPR can present remarkable difficulties, its undeniable advantages will benefit from further improvement of instrumentation. In case of tumors, larger series and longer follow-up will allow evaluation of long-term survival and local recurrence.

Abstract
BACKGROUND Video-assisted lobectomy has been adopted by many thoracic surgeons, because it is a less invasive approach to small peripheral lung cancers. However, some authors disagree that video-assisted lobectomy is less invasive than traditional thoracotomy and lobectomy. The purpose of this study was to evaluate the advantages of video-assisted lobectomy over posterolateral thoracotomy and lobectomy in terms of pain-related morbidity. METHODS A total of 70 patients with clinical T1N0M0 non-small-cell lung carcinomas underwent lobectomy with complete mediastinal lymphadenectomy. Of these 35 underwent posterolateral thoracotomy (between April 1994 and December 1995; open group), and 35 underwent video-assisted thoracic surgery (VATS) (between January and December 1996; VATS group). RESULTS Although the operative time was significantly longer in the VATS group (p = 0.04), the intraoperative blood loss was significantly less (p = 0.03). No significant differences were found for the two groups with respect to the total number of mediastinal lymph nodes dissected or duration of chest tube drainage. Postoperative pain was less severe as determined by the number of doses of analgesics required between postoperative days 0 and 7 (p < 0.0001), and the length of postoperative hospitalization was shorter in the VATS group (p < 0.0001). CONCLUSION Video-assisted lobectomy is associated with decreased postoperative pain and shortened length of postoperative hospitalization, when compared with posterolateral thoracotomy and lobectomy.

Abstract
Thoracoscopy provides a minimally invasive window to the pleural space, lung, and mediastinum. Further advances prompted by improvements of specifically designed endoscopic instruments and procedural techniques are expected. There is no doubt that thoracoscopy has a place among therapeutic procedures in the chest. The time-proven principles of thoracic surgical intervention, particularly in regard to patients with cancer, however, must not be neglected. A beckoning window always offers new opportunities, but the open door of classic surgical techniques should not be ignored.

Abstract
A retrospective study on compromised patients who underwent a lobectomy by a standard thoracotomy for stage I non-small cell lung cancer revealed them to show a poor prognosis and quality of life due to their deteriorated physical conditions. Therefore, a lobectomy by video-assisted thoracic surgery (VATS lobectomy) was performed on some of these patients according to the provisional indications based on our retrospective study which indicated that it may be beneficial. Fourteen patients underwent VATS lobectomies (VATS group). Sixteen patients who underwent lobectomy by standard thoracotomy (ST group) were compared with those of the VATS group as historical controls. Although the mean operating time for the VATS group was longer than that for the ST group, there was no significant difference. The mean amount of blood loss for the VATS group was significantly less than that for the ST group. The mean maximal postoperative serum CPK level of the VATS group was slightly less than that of the ST group. A significant difference was observed regarding the changes in performance status both before and after operation between the VATS group and the ST group. We thus considered a VATS lobectomy to be beneficial for aged patients, especially in those with restricted physical conditions.

Abstract
Video-assisted thoracic surgery (VATS) has enabled more complex procedures previously requiring thoracotomy to be accomplished in lung cancer management. VATS today can be employed in the evaluation of idiopathic (and known) malignant pleural effusions, mediastinal adenopathy, indeterminate pulmonary nodules, and compromise resection and lobectomy of peripheral stage I non-small cell lung cancer. Thus, VATS is becoming an accepted approach to a variety of intrathoracic problems, although its absolute indications for patients with lung cancer have yet to be firmly defined. This article reviews the authors' current experience with VATS procedures in the treatment of patients with lung cancer.

Abstract
In patients who are unable to undergo a lobectomy for a small peripheral lung cancer, a partial thoracoscopic resection appears to be one viable alternative. However, since the regional lymphatics are disrupted in an anatomical fashion with a segmentectomy, it appears superior to a wedge resection. This experimental study was conducted to determine whether or not an anatomical segmental resection is feasible by thoracoscopy. A segmental resection of porcine lungs was performed using thoracoscopy. The segmental vessels were divided between ligatures. The segmental bronchus was divided by an endoscopic stapler. The intersegmental lung parenchyma was divided using a cotton dissector and a contact neodymium-yttrium aluminum garnet laser. Forty-three pigs were divided into seven groups as follows. Group 1: S1 + 2; group 2: S3; group 3: upper division; group 4: lower division; group 5: S6; group 6:S8; and group 7: S9 + 10. The operating times ranged from 145 +/- 15 min to 191 +/- 47 min. Blood loss ranged from 36 +/- 35 ml to 151 +/- 48 ml in all groups. The blood loss in the group with a resection of S6 and S9 + 10 was significantly greater than that of the other five groups. Most of the blood loss occurred during the division between the intersegmental planes. In conclusion, a thoracoscopic segmentectomy is considered to be technically feasible; however, further refinements in this technique are warranted before beginning clinical trials.

Abstract
STUDY OBJECTIVES Video-assisted lobectomy for pulmonary malignancy seems to have potential merits, especially in compromised patients such as the elderly. This study was undertaken to assess the feasibility of this new approach in this special age group. PATIENTS Video-assisted lobectomy was attempted in eight patients older than 78 years of age with preoperatively diagnosed T1N0 or T2N0 lung carcinomas of peripheral origin. In one patient with squamous cell carcinoma, the tumor was diagnosed after surgery as metastasis from tongue carcinoma. The patients ranged in age from 78 to 85 years (average, 81.3 years). RESULTS The procedure was completed successfully in six patients (75%), while the other two patients underwent lobectomy after conversion to open thoracotomy because of bleeding from the pulmonary artery at the hilum in one and extensive pleural adhesions in another. Among the six patients who underwent video-assisted lobectomy, there were no operative deaths or serious complications attributable to this technique, although two patients had prolonged air leakage for 7 and 11 days, respectively. CONCLUSIONS This approach, which is feasible even in patients older than 80 years, is likely to offer a benefit to such patients if they are selected properly. During this procedure, the possibility of wound extension in case of an intraoperative accident must always be borne in mind, especially in elderly patients. The advantage of this approach remains undetermined in this special age group.

Abstract
To examine the usefulness of non-serratus-sparing antero-axillary thoracotomy (AAT) with disconnection of anterior rib cartilage for curative resection of lung cancer, we used retrospective analysis to compare mortality, morbidity, hospital stay, time for thoracic opening, postoperative pulmonary function, and chest pain between AAT and posterolateral thoracotomy (PLT). Subjects were 50 lung cancer patients who underwent lobectomy via AAT (n = 25) or PLT (n = 25), who were matched by sex and age. Chest pain was evaluated using a visual analog scale, a McGill pain questionnaire, and analgesic requirements up to 6 months after surgery. AAT offered adequate exposure for lobectomy and mediastinal lymph node dissection. No difference was observed between the AAT and PLT groups in postoperative mortality, morbidity, or hospital stay. Times for thoracic opening were significantly shorter in AAT than in PLT (p < 0.001). FEV1 and vital capacity 1 week after surgery were significantly preserved in patients with AAT compared with patients with PLT (p < 0.05). Chest pain was significantly reduced in AAT patients compared with PLT patients on 1 day and from 14 days to 6 months after surgery (p < 0.01 to p < 0.001). We conclude that AAT is a reasonable thoracotomy alternative to standard PLT for curative lung cancer resection, because of its adequate exposure, shortened opening time, diminished impairment of postoperative pulmonary function, and reduced chronic postoperative pain.

Abstract
The few reports in the literature on thoracoscopic anatomic lung resections were almost exclusively for early primary lung cancers. We report our combined experience on video-assisted thoracoscopic (VAT) lobectomy for benign diseases from two major hospitals in Hong Kong over a 20-month period. From August 1993 to March 1995, 66 VAT lobectomies were performed; of this number, 10 cases (15%) were for benign diseases (5 tuberculosis, 2 organized pneumonia, 1 bronchiectasis, 1 sclerosing hemangioma, 1 infected bronchogenic cyst). There was no mortality or incidence of intraoperative complications. Postoperative complications occurred in one patient with tuberculosis and consisted of persistent air leak and subsequent wound infection. There were no long-term complications after a mean follow-up of 11 months. The mean duration of chest tube drainage was 6.7 days and that of hospital stay was 9.8 days. These results were not statistically different from those achieved in VAT lobectomies performed for malignant tumors (5.0 days for drainage and 6.8 days for hospital stay) despite the fact that hilar dissection was sometimes more difficult in the former because of inflammatory changes. We conclude that VAT lobectomy for benign diseases is technically feasible even though its role in thoracic surgery remains to be defined.

Abstract
We report our combined experience on video-assisted thoracoscopic (VAT) anatomic lung resections from two major hospitals in Hong Kong over a 17-month period. From August 1993 to December 1994, 82 cases of major lung resections were attempted using the VATS approach, of which 60 were successfully completed (55 lobectomies, 2 bilobectomies, 2 pneumonectomies, and 1 segmentectomy). Of these 60 cases, there were 43 men and 17 women with a mean age of 66 years (range, 37 to 85 years). The final pathologies were 52 primary lung cancers (37 adenocarcinoma, 11 squamous cell carcinoma, 2 bronchoalveolar carcinoma, 1 adenosquamous carcinoma, and 1 undifferentiated carcinoma); 1 pulmonary metastasis (from nasopharyngeal carcinoma); and 7 benign lesions (3 tuberculosis, 1 bronchiectasis, 1 sclerosing hemangioma, 2 organizing pneumonia). There was one postoperative death (mortality rate, 1.8%). Complications include persistent air leak over 10 days (four), wound infection (two), supraventricular tachycardia (three), and recurrence of tumor over the utility thoracotomy scar (one). All the patients were followed up from 8 weeks to 19 months (mean, 10 months). The mean duration of chest drainage was 5.4 days (range, 2 to 25 days). The mean hospital stay was 7.2 days (range, 4 to 35 days). The average postoperative parenteral narcotic (meperidine hydrochloride [Pethidine]) requirement by patient-controlled analgesia was 275 mg (range, 75 to 800 mg). This compared favorably with an age- and sex-matched historic group of patients who underwent posterolateral thoracotomy and had a hospital stay of 10.4 days (statistically non-significant) and narcotic requirement of 950 mg (statistically significant by paired t test). We conclude that VAT anatomic lung resection is technically feasible. However, there are some specific complications associated with major lung resection through minimal access. Refinement of our present technique and attention to details are important to improve our results.

DESIGN Prospective clinical trial. SETTING Clinical pulmonary function laboratory in a university teaching hospital. PATIENTS Twenty-five (mean age, 63 years; 17 men) of 84 consecutive lung resection candidates were considered at increased risk for postoperative complications due to impaired pulmonary function (FEV1 < 2 L or diffusion of carbon monoxide [DCO] < 50% predicted, or FEV1 and DCO < or = 80% predicted combined with New York Heart Association dyspnea index > or = 2). INTERVENTIONS Candidates underwent radionuclide ventilation/perfusion scans and exercise testing to predict postoperative (= ppo) values for FEV1, DCO, and maximal O2 uptake (VO2max). They all underwent thoracotomy for neoplastic lesions; 7 had pneumonectomies, 18 lobectomies. Six patients had postoperative complications (within 30 days), of whom three died. Three and 6 months postoperatively, pulmonary function tests and VO2max were repeated. MEASUREMENTS AND RESULTS In the 22 survivors, the observed values were then compared with the predicted values. At 3 months, there were excellent correlations (absolute/predicted values): for FEV1 r = 0.78 and 0.81; for DCO, r = 0.77 and 0.74; and for VO2max, r = 0.71 and 0.83. The means of FEV1 and VO2max did not differ from the predicted values, whereas the predicted DCO was lower than the observed value (mL/min/mm Hg: 15.1 vs 17.9; percent predicted: 59.6 vs 70.9) (p < 0.05). At 6 months, correlations remained very good for FEV1 (r = 0.81 and 0.84) and for DCO (r = 0.76 and 0.74), but had decreased for VO2max to 0.56 and 0.65, respectively. All means were higher than predicted (p < 0.05) owing to recovery in the lobectomy group. Patients with postoperative complications (group B) had a lower preoperative VO2max in percent predicted (62.8 +/- 7.5% vs 84.6 +/- 19.7%) (p < 0.01) and also a lower VO2max-ppo (10.6 +/- 3.6 vs 14.8 +/- 3.5 mL/kg/min and 44.3 +/- 13.5 vs 68.0 +/- 20.7% predicted) (p < 0.05) than patients without complications (group A). A VO2max-ppo < 10 mL/kg/min was associated with a 100% mortality. Although FEV1-ppo and DCO-ppo were lower in group B, the difference did not reach significance. CONCLUSIONS Radionuclide-based calculations of postoperative VO2max are predictive of operative morbidity and mortality: a VO2max-ppo of < 10 mL/kg/min may indicate inoperability. Further, short-term postoperative performance is accurately predicted by FEV1-ppo and VO2max-ppo, but long-term function is underestimated after lobectomy.

Abstract
OBJECTIVE To assess a standard classification of adverse events and evaluate the safety and long-term outcome of thoracoscopy in patients with pleural disease. DESIGN Prospective nonrandomized cohort study. SETTING The Pulmonary Special Procedures and Nd:YAG Laser Unit of the University of California San Diego Medical Center, San Diego. PATIENTS Fifty consecutive patients undergoing thoracoscopy for diagnosis of pleural effusion or thickening, pleurodesis, or empyema drainage. INTERVENTION A list of major and minor adverse events that could be temporally related to thoracoscopy performed for diagnosis or treatment of pleural processes was established before beginning this prospective study. Procedures were performed using multiple point-of-entry techniques and either local or general anesthesia. Most procedures were performed in the operating room using double-lumen intubation. Patients were seen daily during hospitalization and at least 7, 30, and 90 days after thoracoscopy. Long-term follow-up data were obtained by telephone calls, clinical visits, or medical chart reviews or all of these, until 12 months after procedures. MEASUREMENTS Occurrence of major and minor adverse events possibly related to thoracoscopy was recorded prospectively. Demographic and clinical data, as well as efficacy and outcome after thoracoscopy, were also noted. RESULTS Fifty-two procedures were performed in 50 patients. Median age was 60 years (range, 18 to 88 years). Thoracoscopy provided a diagnosis in 93% of patients with pleural disease of unclear origin. Pleurodesis by thoracoscopic talc insufflation was successful in 95% of cases and in 91% of patients with malignant pleural effusions still available for evaluation and follow-up examination 3 months after pleurodesis. Thoracoscopic drainage of empyema was successful in six of seven patients and led to referral for open decortication in one. There were no procedure-related deaths or intraoperative accidents. Open-chest surgery intervention was never required. Only 1 major adverse event occurred: a patient with scleroderma and trapped lung had recurrent pleural effusion requiring chest tube drainage 1 week after hospital discharge. Minor adverse events, however, were noted in ten instances (19%). These included fever after talc pleurodesis, asymptomatic pneumothorax after chest tube removal, and minor would infection in a patient with empyema. CONCLUSION Using the proposed classification of major and minor adverse events, prospective evaluation demonstrated the safety, diagnostic utility, and long-term efficacy of thoracoscopy performed for diagnosis and management of pleural processes. Potential dangers, however, of thoracoscopy are acknowledged, and limitations of the procedure are addressed.

Abstract
We describe a 'homemade' knot pusher modified from a conventional right angle dissector for extracorporeal ties. The knot pusher has the advantage of allowing the operator to control the tension applied to the structure to be ligated. The instrument can be made with simple tools and its use can be easily learnt. We have used this device in 10 video assisted thoracoscopic lobectomies (over 100 applications on pulmonary vascular structures) without complications. This device can also be used in 'open' surgery when knot tying is needed through a deep wound.

Abstract
Advances in video-assisted thoracoscopic (VAT) surgery allow it to assume an increasingly important therapeutic role. Two successful VAT lobectomies (left upper lobe and right lower lobe) were performed in patients with stage I adenocarcinoma. An 8 cm access minithoracotomy for hilar dissection and subsequent specimen delivery was used. Routine mediastinal node sampling was performed thoracoscopically as would be done conventionally. Video-assisted thoracoscopic lobectomy of the right upper lobe was attempted in another patient but he required emergency conversion to open thoracotomy because of bleeding from mechanical failure of the vascular staple-cutter. Although VAT lobectomy is feasible technically, attention to detail is important when mechanical devices are used to minimize the chance of malfunctioning. Once disaster occurs the surgeon should be capable of dealing with the consequences.

Abstract
BACKGROUND Preliminary experience of video assisted thoracoscopic pneumonectomy in six patients with bronchogenic carcinoma is described. METHODS Four left and two right pneumonectomies were performed under video thoracoscopic imaging. Thoracoscopic instruments were passed through two separate stab incisions on the lateral chest wall and a separate 6 cm submammary incision was also created to allow further access for instrumentation and removal of the resected lung. In this initial experience resection was restricted to patients with bronchogenic carcinomas of less than 6 cm in diameter who had no involvement of the mediastinum. RESULTS There were no operative deaths and no complications attributable to the technique. One patient developed postoperative atrial fibrillation and a small sacral sore and one patient was readmitted with abdominal pain and pyrexia which settled following exclusion of post pneumonectomy empyema. The remaining four patients made a rapid uncomplicated postoperative recovery with less pain and discomfort than that normally associated with a standard posterolateral thoracotomy. Postoperatively the mean (SD) patient controlled morphine consumption was 1.36 (1.90) mg per hour in the first 36 hours compared with the unit mean for open thoracotomy of 1.73 (1.68) mg per hour. The mean linear visual analogue pain score was 15.4 (15.6) in the first 24 hours compared with the unit mean for open thoracotomy of 34.5 (8.5). CONCLUSIONS Video assisted thoracoscopic pneumonectomy can be performed safely in patients who have stage I and stage II bronchogenic carcinomas, up to 6 cm in diameter, with no mediastinal involvement on mediastinoscopy and thoracic computed tomographic assessment. This technique may result in less postoperative pain and discomfort and should allow a quicker return to normal activities.

Abstract
Videothoracoscopy, routinely performed as the initial step of an operation, opens interesting opportunities for both the operative staging and treatment of lung cancer. Videosurgical maneuvers ensure thorough exploration of the cavity, thus avoiding unnecessary exploratory thoracotomies, confirming resectability of the lesion by open or, in selected cases, by a direct video-assisted approach. We report our experience of 155 patients submitted to videothoracoscopic operative staging between October 1991 and January 1994. Videothoracoscopic operative staging showed unresectability in 13 patients (8.3%) due to preoperatively unexpected (10 patients) or suspected conditions (3 patients). The remaining 142 patients were divided by staging of the lesion and general conditions into three groups. Group A consisted of 13 elderly patients with small peripheral tumor who could not tolerate lobectomy and who underwent thoracoscopic wedge resection. Group B consisted of 63 patients with peripheral clinical T1 N0 or T2 N0 tumor. Fifty-two lobectomies and 4 pneumonectomies were carried out thoracoscopically. Seven conversions to thoracotomy were necessary due to technical problems. The postoperative course was uneventful in 51, 5 had prolonged air leakage, and a bronchial fistula developed in 1 because of positive-pressure postoperative ventilation. Group C consisted of 66 patients with stage II or IIIa neoplasm. Thoracotomy after thoracoscopy proved unresectability in 4, whereas 62 were submitted to a radical pulmonary resection. In the literature the incidence of exploratory thoracotomies for conditions missed by preoperative staging still remains high. After adoption of videothoracoscopic operative staging we reported a 2.6% exploratory thoracotomy rate.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A preliminary report is made on the use of videothoracoscopy to achieve pulmonary lobectomy in 16 patients, including 12 with centrally located pulmonary metastases and 4 with benign lesions (3 bronchiectases and 1 endobronchial hamartoma). Videothoracoscopy was performed on eight right-lower lobes, one middle lobe, two right-upper lobes, four left-lower lobes, and one left-upper lobe with a thoracoscope and conventional thoracic instruments. All patients received standard pulmonary lobe resection with lymph node clearance similar to that achieved with open thoracotomy. The mean operative time was 3 h (range, 2.5 to 4 h). Average blood loss was 100 mL and mean length of hospital stay was 6 days (range, 4 to 8 days). A combination of videothoracoscopy with use of conventional instruments resulted in similar performance but less chest wall interruption than in conventional pulmonary lobectomy. Videothoracoscopy showed safer and faster lung resection, which subsequently minimized the perioperative morbidity. Pain intensity was lessened, functional recovery was quicker, and hospital stays were shorter in the patients we reviewed.

Abstract
In a series of 57 patients undergoing thoracoscopic pulmonary lobectomy, 2 required expeditious conversion to open thoracotomy when a stapling device (Endo-GIA 30 V3; Autosuture, Ascot, UK) used on the main right lower pulmonary artery in 1 case and on the left superior pulmonary vein in the other cut but failed to staple the vessel involved. In both instances the vessel was successfully controlled while a thoracotomy was performed and the involved vessel was oversewn. Both patients made an uncomplicated postoperative recovery. As the number of thoracoscopic pulmonary resections increases, it is likely that similar episodes will occur in the future. These cases strongly emphasize the fact that patients undergoing this procedure should do so in a center specializing in thoracic surgery where there is the necessary surgical expertise and equipment to deal with such potentially life-threatening vascular complications.

Abstract
Tumor implantation after video-assisted thoracic operations is rare. We describe the case of a 61-year-old woman who underwent an apparently uneventful thoracoscopic resection of a solitary pulmonary metastasis from a primary limb sarcoma. Within 3 months, extensive trocar and diaphragmatic implants developed that required an extensive en bloc resection of her chest wall, diaphragm, and lung. Because of the aggressive biologic behavior of sarcomas and their potential to grow in surgical tracts, concern is raised about the advisability of using video-assisted thoracic surgical techniques in the management of these tumors.

Abstract
Recent developments in video camera techniques, new instruments and advanced surgical techniques have increased the importance of thoracoscopy in both the diagnosis and therapy of diseases of the chest. Many diseases previously demanding open thoracotomy (i.e. spontaneous pneumothorax, biopsies of lung, pleura and mediastinum, several benign intrathoracic tumours, achalasia and reflux disease of the esophagus) can, today, be treated by video-assisted thoracic surgery with the same results as by using open procedures. The advantages of this technique compared to open thoracotomy include less operative trauma, less postoperative pain, good cosmetic results and shorter hospital stay. The drawbacks are the more difficult technique, demanding special education, the possibility of inadequate radicality in the treatment of malignant diseases and the necessity of longer operating time. The physician performing thoracoscopic surgery must also master the techniques of open procedures.

Abstract
We prospectively analyzed the outcome of lobectomy in a cohort of 67 patients. Operative time, postoperative pain, pulmonary function, and early outcome were compared between the patients undergoing video-assisted techniques (n = 44) and those undergoing standard muscle-sparing procedures (n = 23). Pain was quantified daily throughout the first week using the visual analog scale. The forced expiratory volume in 1 second and the forced vital capacity were measured at days 2, 4, and 8 postoperatively. The operative time was significantly longer (p < 0.02) and the postoperative pain was significantly less (p < 0.006) in the group undergoing video-assisted procedures. Pain-related morbidity, the mean duration of air leaks, the duration of chest tube placement, and the hospital stay were all less in the video-assisted group, but the differences did not reach statistical significance. However, the impairment in pulmonary function and the overall morbidity were identical for the two groups. Based on our findings, we conclude that video-assisted minithoracotomy is a safe and reliable approach for performing lobectomies, and that the decreased postoperative pain associated with this minimally invasive approach does not result in preserved pulmonary function and significantly reduced morbidity when compared with a muscle-sparing thoracotomy.
