Successful thoracoscopic repair of esophageal atresia with tracheoesophageal fistula in a newborn with single ventricle physiology.

UNLABELLED: A neonate with VACTERL association including tricuspid atresia was scheduled for thoracoscopic esophageal atresia with tracheoesophageal fistula (EA/TEF) repair and laparoscopic gastrostomy tube placement. In addition to standard noninvasive monitoring, arterial blood pressure, central venous pressure, and cerebral oxygen saturation were monitored. Gastric distension resulting from positive pressure ventilation prevented laparoscopic gastrostomy tube placement. Thoracoscopy with a CO2 insufflation pressure of 6 mm Hg at low flow (1 L/min) was well tolerated hemodynamically despite hypercarbia and cerebral oxygen saturation was maintained. Careful monitoring and good communication were critical to the safe management of this single ventricle patient during thoracoscopic EA/TEF repair. IMPLICATIONS: Esophageal and tracheoesophageal fistula in conjunction with single ventricle physiology carries a significant risk of mortality. We present the anesthetic management of a neonate with unpalliated tricuspid atresia who underwent thoracoscopic tracheoesophageal fistula repair.

Thoracoscopic Nd:YAG laser resection of a solitary pulmonary nodule.

Advances in endoscopic surgical techniques and laser technology have expanded the role of thoracoscopy. We report a thoracoscopic resection of a benign pulmonary lesion. A 44-year-old man underwent a successful Nd:YAG laser-assisted thoracoscopic resection of a peripheral lung hamartoma. The patient's postoperative course was uncomplicated. Thoracotomy with its attendant morbidity was avoided. Continued success with thoracoscopic resection will have a significant impact on the management of select patients with peripheral, solitary pulmonary nodules.

The hook-wire technique for localization of pulmonary nodules during thoracoscopic resection.

The main problem related to the thoracoscopic resection of lung nodules is the difficulty in locating the target nodule. Among the several methods proposed, one of the most efficient is the preoperative placement of a localization wire into the nodule while it is under computed tomography scan control. After our initial series of 22 thoracoscopic resections of lung nodules without preoperative localization, we have used the hook-wire technique in 21 patients. In our initial series, we had four failures while we have had only one in the hook-wire series. Only two minor complications related to the wire localization technique occurred: a poorly tolerated pneumothorax and an intrapulmonary hemorrhage. There was no postoperative complication. The mean duration of postoperative stay was 1 to 6 days. We conclude that the preoperative localization of lung nodules using a hook wire is a safe and accurate method before thoracoscopic resection in selected patients.

A comparison of thoracoscopic talc insufflation, slurry, and mechanical abrasion pleurodesis.

The purpose of this study was to compare the anatomic and histopathologic results of four different methods of pleurodesis in 10 dogs. Each animal was randomly assigned to receive two of the following methods of pleurodesis: thoracoscopic talc insufflation (poudrage), talc slurry administration, focal gauze abrasion by limited thoracotomy, and mechanical abrasion by thoracoscopy using a commercially available pleural abrader. Animals were killed 30 days after pleurodesis. At autopsy, the efficacy of pleurodesis was graded by evaluating the gross appearance of each pleural cavity and lung (pleurodesis score), and by determining the extent of adhesion formation (obliteration grade). Pleural and lung biopsy specimens were obtained from the areas most representative of adhesion formation for histopathologic evaluation. Pleurodesis scores (on a scale of 0 to 4) were 3.0 +/- 0.7 for talc poudrage (p < 0.05 when compared with talc slurry), 2.2 +/- 1.7 for thoracotomy, and 1.6 +/- 1.1 for talc slurry. Adhesions produced by gauze abrasion during thoracotomy were mostly peri-incisional. Thoracoscopic pleural abrasion using the pleural abrader was uniformly unsatisfactory. Granulation tissue formation was greatest in both talc models. The degree of parietal pleural thickening was greatest in the talc slurry model, but fibrosis and inflammation occurred mostly in gravity-dependent areas within the pleural cavity. Although differences were not statistically significant, thoracoscopic talc insufflation consistently produced the most widespread, firm fibrotic adhesions as evidenced by higher obliteration grades.

The role of radiologic imaging in diagnosing complications of video-assisted thoracoscopic surgery.

STUDY OBJECTIVE: To examine the role of radiologic imaging in evaluating complications of video-assisted thoracoscopic surgery. DESIGN: Retrospective review of radiographic and clinical data. SETTING: Tertiary referral hospital. PATIENTS: All patients who underwent thoracoscopy at the University of Maryland Hospital between July 1990 and June 1994. A total of 260 procedures were performed on 239 patients. MEASUREMENTS AND RESULTS: Imaging studies performed before, during, and after surgery in cases in which complications occurred were reviewed by two thoracic radiologists. A randomly selected group of 22 CT scans from uncomplicated cases were used as control subjects. Complications occurred in 24 (9.2%) of the 260 thoracoscopic procedures. Intraoperative complications developed in 14 (5.4%) patients. Ten of the 14 patients had an obliterated pleural space that prevented access of the trocars and videoscope. Preoperative imaging showed significant pleural thickening or calcifications in seven of these ten patients. Other intraoperative complications were malposition of the double-lumen endotracheal tube (n=2) and dislodgement of a localizing needle-wire (n=2). In 8 (3.1%) patients, radiographically evident postoperative complications developed; these complications included prolonged air leak, empyema, recurrent pneumothorax, pulmonary edema, and pneumonia. CONCLUSION: Pleural calcification or thickening that is found on preoperative studies may help predict difficulty in inserting the thoracoscopic instruments but also can be seen on preoperative CT scans in uncomplicated cases. Thoracic CT scans may fail to predict complete pleural symphysis.

Medical thoracoscopic talc pleurodesis for chylothorax due to lymphoma: a case series.

STUDY OBJECTIVES: Recurrent chylothorax as a complication of lymphoma has had unsatisfactory outcomes. Serial thoracentesis, tube thoracostomy, and pleurodesis via chest tube have been ineffective and compromise the nutritional and immune status of the patient. Medical thoracoscopic talc pleurodesis has been safe and effective in the treatment of some other varieties of recurrent pleural effusions. Our objective was to investigate the safety and efficacy of medical thoracoscopic talc pleurodesis in the palliation of chylothorax related to lymphoma. DESIGN: This is a report of 24 hemithoraces treated in 19 consecutive patients with lymphoma-related chylothorax, failing chemotherapy or radiation therapy. The average patient age was 55 years. INTERVENTIONS: Medical thoracoscopy was performed under local anesthesia and conscious sedation in a bronchoscopy suite. Sedation included midazolam (mean dose, 6 mg; range, 2-14 mg) with either meperidine (mean dose, 94 mg; range 25-140 mg), or morphine (mean dose, 18 mg; range 4-40 mg). Pleurodesis was performed with insufflation of sterile asbestos-free talc, (4-8 g). After pleurodesis, chest tubes were placed, with the mean duration of chest tube placement being 4 days, range 3 to 10 days. RESULTS: One patient died a few days after the procedure due to causes related to the primary disease process. Follow-up was for at least 90 days following the procedure. Patients were assessed at 30, 60, and 90 days following the procedure. At each of these endpoints, all patients remaining alive were without recurrence of pleural effusions, which was confirmed by chest radiography. Eight patients in the series died of the effects of their malignancy during the 90-day evaluation interval. Complications included medication reactions in two patients (8.3%) and ARDS in one patient (4.1%). CONCLUSION: Many patients with lymphoma-related chylothorax are refractory to chemotherapy and/or radiation therapy. In this group, medical thoracoscopic talc pleurodesis has an acceptable complication rate and a 100% success rate in the prevention of recurrence of pleural effusions at 30, 60, and 90 days following the procedure.

Thoracoscopic resection of solitary lung metastases from colorectal cancer is a viable therapeutic option.

STUDY OBJECTIVES: The reported 5-year survival rate after pulmonary metastasectomy from colorectal carcinoma, usually accomplished through thoracotomy or median sternotomy, ranges from 9 to 47%. Video-assisted thoracoscopy (VAT) is employed routinely for many thoracic surgical procedures, but the main concern about this approach for resection of lung metastases is that VAT does not allow complete lung palpation to identify and remove metastases not detected by preoperative radiologic examinations. DESIGN: In this study, we reviewed our experience with thoracoscopic resection of single peripheral lung metastases from colorectal carcinoma with potentially curative intent. PATIENTS AND INTERVENTIONS: From July 1992 to September 1998, 24 patients (15 male, 9 female) with a mean age of 56 years, who previously had undergone resection for colorectal carcinoma and had a single limited and peripheral lung lesion identified by high-resolution CT, underwent thoracoscopic wedge resection of the lesions. RESULTS: No intraoperative complications developed. Three patients had minor postoperative complications successfully treated. In one case, we found a benign lesion, and this patient was excluded from the analysis. In the remaining cases, metastases from colorectal cancer were confirmed. The median follow-up was 29 months, ranging from 3 to 67 months. Thirteen patients (56.5%) developed recurrence of the disease, and 5 of them (21.7%) had local recurrence. Cumulative 5-year survival estimated by Kaplan-Meier method was 49.5%, not really different from the data reported in the literature. CONCLUSIONS: Thoracoscopic resection of single peripheral lung metastases from colorectal cancer with potentially curative intent seems effective and justified since the ultimate outcome of this highly selected group of patients seems to be not different from that obtained after a more invasive approach.

The results of thoracoscopic surgery for primary spontaneous pneumothorax.

OBJECTIVE: To review our experience of video-assisted thoracoscopic surgery for the treatment of primary spontaneous pneumothorax. DESIGN: Longitudinal cohort study following up consecutive patients for 3 to 4.3 years. SETTING: Thoracic Surgery Department, Chest Diseases Hospital, Kuwait. PATIENTS AND INTERVENTION: Seventy-two consecutive patients undergoing thoracoscopy for primary spontaneous pneumothorax from January 1994 to June 1996. RESULTS: The mean age of the patients was 25 years (range, 15 to 40 years), and 67 were men (93%). All patients were successfully treated using video-assisted thoracoscopic technique. Recurrent pneumothorax was the most frequent indication for surgery, occurring in 49 patients. The most common method of management was stapling of an identified bleb, which was done in 56 cases. Pleurodesis was achieved by gauze abrasion (n = 39) and apical pleurectomy (n = 33). Postoperative prolonged air leak occurred in five patients (6.9%). There were no deaths attributable to the procedure. The mean (+/-SD) postoperative hospital stay was 4 +/- 2 days. Mean follow-up is 42 months (range, 36 to 54 months) for all patients. Pneumothorax recurred in four patients (5.5%) in whom pleural abrasion was done. The recurrences occurred in the first year of follow-up, three required a reoperation, and one healed by rest without pleural drainage. CONCLUSIONS: Video-assisted thoracoscopic surgery is a safe procedure in the treatment of primary spontaneous pneumothorax. Apical pleurectomy is a more effective way of producing pleural symphysis. Long-term follow-up did not increase the rate of recurrence.

Video-assisted thoracoscopic sterilization for exacerbation of chronic empyema thoracis.

STUDY OBJECTIVE: To investigate the efficacy of video-assisted thoracoscopic sterilization to treat patients with exacerbation of chronic empyema thoracis. DESIGN: Case reports and literature review. SETTING: Academic department of surgery. PATIENTS: Two elderly, debilitated patients with worsening, chronic empyema thoracis as diagnosed by radiographs, CT, and thoracentesis. Both patients had a history of therapeutic pneumothorax for tuberculosis without bronchopleural fistulas. INTERVENTIONS: Video-assisted thoracoscopic sterilization of the thoracic cavity. MEASUREMENTS AND RESULTS: There was no recurrence of empyema during a 6-year follow-up period for one patient and a 2.5-year follow-up period for the other patient. CONCLUSIONS: Video-assisted thoracoscopic sterilization is a minimally invasive useful treatment for elderly or debilitated patients with exacerbation of chronic empyema thoracis.

Ultrathin bronchoscopic barium marking with virtual bronchoscopic navigation for fluoroscopy-assisted thoracoscopic surgery.

STUDY OBJECTIVES: To facilitate marking and to reduce its complications, we performed barium marking using an ultrathin bronchoscope with virtual bronchoscopic (VB) navigation before thoracoscopic surgery for small pulmonary peripheral lesions. We then evaluated the feasibility, safety, and efficacy of this technique. DESIGN: A pilot study. SETTING: A tertiary teaching hospital. PATIENTS: The subjects were consecutive patients with small pulmonary peripheral lesions (ie, </= 10 mm) showing a CT scan-confirmed pure ground-glass opacity pattern between December 2001 and August 2003. INTERVENTIONS: VB images to the planned marking sites near each lesion were produced from helical CT scan data. Based on these images, an ultrathin bronchoscope was advanced to the target bronchus under direct vision. Under CT scan and radiographic fluoroscopy, a catheter was inserted to the planned site via the bronchoscope, and barium sulfate suspension was instilled for marking. RESULTS: The subjects were 23 patients (8 men and 15 women) who had a total of 31 lesions. The bronchial branching patterns seen in VB images were highly consistent with those confirmed using the ultrathin bronchoscope. Therefore, the ultrathin bronchoscope could be guided under direct vision to a median of the sixth generation bronchi (range, fourth to ninth generation bronchi) toward the planned marking sites. Marking was achieved without causing complications in any of the patients. The median marking time was 23.5 min, and the median shortest distance between the barium marker and the lesion was 4 mm (within 10 mm in 27 lesions). In patients undergoing thoracoscopic surgery, all barium-marked sites were identified by intraoperative radiographic fluoroscopy, and all lesions were resected. A pathologic examination demonstrated primary lung cancer in 17 lesions (bronchioloalveolar carcinoma, 15; adenocarcinoma, 2), atypical adenomatous hyperplasia in 12 lesions, and pneumonia in 2 lesions. CONCLUSIONS: This method can be readily performed without complications and is a useful marking method before thoracoscopic surgery for small pulmonary peripheral lesions.

Role of video-assisted thoracoscopic sympathectomy in the treatment of primary hyperhidrosis.

CONTEXT: Essential hyperhidrosis is a frequent disorder causing significant functional impairment. The advent and development of video-assisted thoracoscopic techniques now allows thoracic sympathectomy to be carried out precisely and safety with good results and minimal morbidity. OBJECTIVE: To assess the impact of video-assisted thoracic sympathectomy in patients diagnosed as presenting severe and disabling hyperhidrosis. TYPE OF STUDY: This was a longitudinal study of the clinical course of all hyperhidrosis cases selected for surgery between May 1999 and January 2003. SETTING: Division of Thoracic Surgery, Universidade Federal de S o Paulo (UNIFESP). PARTICIPANTS: 743 patients with surgery indicated due to palmar hyperhidrosis (49.8%), palmar-axillary hyperhidrosis (38.1%), craniofacial hyperhidrosis (8.9%) or isolated axillary hyperhidrosis (2.8%). PROCEDURES: Video-thoracoscopic sympathectomy was performed, isolating the second thoracic ganglion (T2) in all patients, with additional sympathectomy of T3 and T4 if necessary. MAIN MEASUREMENTS: The clinical course was followed up via questionnaires, phone calls, letters and statements. Simple questions were asked regarding the disappearance of symptoms and presence and intensity of compensatory sweating. RESULTS: The surgery was regarded as efficient in all cases of palmar hyperhidrosis. In the craniofacial hyperhidrosis cases, partial recurrence of the symptoms occurred in 2 cases (3.0%). Partial recurrence or persistence of symptoms occurred in 20% of the patients with predominantly axillary symptomatology. The compensatory sweating was considered disagreeable or uncomfortable by about 30% of the patients, but it only reached the level of regretting the operation for 3% of them. This occurred more frequently in patients with axillary hyperhidrosis. Ten cases of complications occurred. CONCLUSION: Thoracoscopic sympathectomy provides very good results in most patients, with a very low complication rate. However, the assessment of surgical results using conventional methods is imprecise and inaccurate. Different methodology, including quality of life assessment, must be used for comparing results and providing objective data on the results of this operation.

Thoracoscopic partial pericardiectomy in 13 dogs.

Thirteen dogs with cardiac tamponade resulting from pericardial effusion were prospectively evaluated to determine feasibility and outcome of thoracoscopic partial pericardiectomy. A lateral thoracoscopic approach allowed adequate exposure to remove a 4- to 5-cm-diameter section of pericardium in all dogs. Complete resolution of cardiac tamponade occurred in all dogs for which there was follow-up (11 dogs). Ten of 13 dogs (76.9%) had neoplastic pericardial effusion. One of these dogs remains alive at 220 days postoperatively and is asymptomatic. The mean survival of the remaining 9 patents with neoplastic effusion was 128 days (range, 14-544 days; median, 38 days). Three of 13 patients (23.1%) had idiopathic pericardial effusion. Two of these dogs remain alive at 585 and 1,250 days postoperatively. One dog with idiopathic pericardial effusion developed cardiomyopathy and was euthanized 18 days after the procedure. Results indicate that the procedure was technically successful in all dogs. No anesthetic complications occurred. Procedural complications included phrenic nerve transection (1 dog), lung laceration (1 dog), and moderate intraoperative bleeding (1 dog). No adverse clinical manifestations of the complications were apparent. We conclude that thoracoscopic partial pericardiectomy is technically feasible and offers several advantages over conventional open thoracic surgical pericardiectomy.

Efficacy of thoracoscopic lung biopsy in interstitial lung diseases: comparison with open lung biopsy.

OBJECTIVE: To determine the efficacy of video-assisted thoracoscopic surgery (VATS) compared to open lung biopsy. DESIGN: Descriptive, observational case series. PLACE AND DURATION OF STUDY: The Cardio-thoracic Centre, Liverpool, UK, from January 1995 to December 1999. PATIENTS AND METHODS: One hundred consecutive patients, undergoing lung biopsy for interstitial lung disease during this period, were included in the study. Thirty patients underwent open lung biopsy, while 70 patients had VATS lung biopsy. Patient characteristics, site, size, number and laterality of biopsy, complications, morbidity, mortality and diagnostic yield was compared. P-value was determined to assess significance of findings. Statistical analysis was performed on SAS for windows version 8. RESULTS: Seventy-five percent had diagnostic yield in VATS group, while 37% in open group (p=0.04). Mean FEV1 was 3.2 litre in VATS group and 1.92 litre in open group (p=0.05). Right side was selected in 58.6% in VATS group and 36.7% in open group (p =0.04). Right lower lobe was the main site for biopsy in the VATS group compared to open group (18.6% versus 3.3%, p=0.04). Mean volume of biopsy was 15.6 cm3 in VATS group and 12.5 cm3 in open group (p=0.04). Two or more biopsies were carried out in 37.1% of the VATS group compared to 16.7% of the open group (p=0.04). Chest drain duration was in 1 day in VATS group compared to 2 days in open group (p=0.01). Length of stay was 3 days in VATS group and 4 days in open group (p=0.003). CONCLUSION: Patients undergoing thoracoscopic lung biopsy had a significantly reduced chest drain duration and post-operative length of stay. Thoracoscopic lung biopsy is beneficial in determining a diagnostic yield with an advantage of greater volume and selection of biopsy sites.

Using a dedicated lung-marker system for localization of pulmonary nodules before thoracoscopic surgery.

OBJECTIVE: Our aim was to evaluate the effectiveness of a commercially available dedicated lung-marker system for localization of pulmonary nodules before video-assisted thoracoscopic surgery. SUBJECTS AND METHODS: Guidewires were positioned under CT fluoroscopy guidance in 16 patients (11 men, five women; age range, 39-79 years; mean age, 60.4 years). We measured the size of the targeted nodule, its distance to the closest pleural surface, the angle between the introducer needle and the chest wall, and the time for performance of the procedure in each patient. Note was made of any complications after guidewire placement. RESULTS: In the 16 patients, the average nodule size was 6.7 mm (range, 3-12 mm), the average distance to the pleural surface was 10.6 mm (range, 3-22 mm), and the average pleural puncture angle was 59 degrees (range, 25-78 degrees). The marking procedure was completed within an average of 9.5 min (range, 7-15 min). Small pneumothoraces occurred in five (31.3%) of 16 patients. In 15 (93.8%) of 16 patients, thoracoscopic resection of the targeted nodule was successful; in one patient with dyspnea (6.3%), inaccurate localization resulting in an open thoracotomy occurred because an intervening fissure was not visualized. Dislodgement of the guidewire into the pleural space occurred in one patient (6.3%). CONCLUSION: The dedicated lung-marker system is a fast and effective method for localization of pulmonary nodules before thoracoscopic resection.

Thoracoscopic resection of parenchymal blebs in spontaneous pneumothorax. Indications, operative management and results.

The success rate of thoracoscopic resection of parenchymal blebs in spontaneous pneumothorax was evaluated after 54 thoracoscopies (cases) in 52 patients. Switch to open thoracotomy was necessitated by interpleural adhesions or large bullae in five cases, while 49 were treated thoracoscopically. The median duration of the operation was 75 (25-240) min, and the postoperative hospital stay was 7 (3-25) days. Early postoperative complications were haemothorax and recurrence of pneumothorax, each in one case, treated with thoracoscopy and chest drain, respectively. Forty-six patients were followed up for a median of 11 (1-32) months. there were two recurrences (at 4 and 6 months). One was successfully treated with thoracoscopy and the other with thoracotomy. Only five patients complained of slight sensitivity in the scar area, caused by weather changes. Thoracoscopic bleb resection is an effective alternative to thoracotomy, with low rates of complications and recurrent pneumothorax.

Thoracoscopic sympathectomy: techniques and outcomes.

Thoracic sympathectomy is an important option in the treatment of palmar hyperhidrosis and pain disorders. Earlier surgical procedures were highly invasive with known morbidity, acceptable outcome, and established recurrence rates that were the limitations to considering surgical treatment. Thoracoscopic sympathectomy is a minimally invasive procedure that allows detailed visualization of the sympathetic ganglia and minimal postoperative morbidity; however, outcome studies of this technique have been limited. The authors treated 39 patients with 60 thoracoscopic procedures, and the outcomes in this small series were equivalent to previously established open surgical techniques; however, operative moribidity rates, hospital stay, and time of return to normal activity were substantially reduced. Complications and recurrence of symptoms were also comparable to previous reports. Overall patient satisfaction and willingness to repeat the operative procedure ranged from 66 to 96% in all patients. Patients and physicians can consider minimally invasive thoracoscopic sympathectomy procedures as an option to treat sympathetically mediated disorders because of the procedure's reduced morbidity and at least equivalent outcome rates in comparison to other treatments.

Thoracoscopic resection of thoracic neurogenic tumors.

OBJECT: The authors describe the treatment and results of thoracoscopic resection performed in patients with neurogenic tumors. METHODS: Seven patients with large intrathoracic paraspinal neurogenic tumors underwent a thoracoscopic procedure to achieve gross-total resection. All tumors were entirely intrathoracic and treated thoracoscopically except in one patient whose tumor had an intraspinal extension. Gross-total resection was achieved in all cases. Postoperatively, one patient developed Homer syndrome. The only other complication, transient intercostal neuralgia, resolved in all patients. Clinical examination and magnetic resonance imaging follow-up examination in all patients demonstrated no evidence of recurrent disease (mean follow up 12.5 months). CONCLUSIONS: Endoscopic transthoracic approaches can reduce approach-related soft-tissue morbidity and facilitate a patient's recovery by preserving the normal tissues of the chest wall, by avoiding rib retraction and muscle transection, and by reducing postoperative pain.

Thoracoscopic talc poudrage pleurodesis for chronic recurrent pleural effusions.

OBJECTIVE: To assess the effectiveness of thoracoscopic talc poudrage for the treatment of chronic pleural effusions. DESIGN: Prospective evaluation. SETTING: Kaiser-Permanente Hospital. PATIENTS: Forty-seven consecutive patients with recalcitrant pleural effusions, referred for thoracoscopy. INTERVENTION: Patients received general or local anesthesia; 42 had a 7-mm rigid thoracoscopic examination followed by insufflation of 5 mL of talc. Patients then had chest-tube drainage. MEASUREMENTS: We recorded clinical characteristics, final diagnosis, procedure-related pain and morbidity, days of hospitalization, patient-reported degree of symptom relief, and chest roentgenographic results at 1, 3, and 12 months. All patients were followed for 16 months or until death. MAIN RESULTS: Of 39 evaluable patients, all reported prolonged relief of effusion-related dyspnea. Radiographic results confirmed the elimination of pleural effusions in 34 patients (87%), including all 11 with benign conditions and 23 of 28 (82%) with malignancies. Treatment failed in three patients because of entrapped lung and in two patients with mesotheliomas whose effusions recurred more than a year after treatment. No procedure-related mortality or morbidity was found. Ambulatory patients required hospitalization for a mean of 3.9 days (range, 2 to 11 days). Mild pain was reported by some patients. The mean duration of chest-tube drainage was 2.7 days (range, 1 to 9 days). Patients with malignant disease lived an average of 12.4 months (range, 1 to 61 months) after the procedure. CONCLUSIONS: Thoracoscopic talc poudrage is an effective pleural sclerosing technique and is relatively painless.
