OBJECTIVES Lung volume reduction surgery (LVRS) improves dyspnoea, quality of life and may even prolong survival in carefully selected patients with end-stage emphysema. The benefit may be sustained for several years and vanishes with the natural progression of the disease. Data on repeated surgical treatment of emphysema are scarce. The aim of this study was to evaluate the safety, effects and outcomes of repeated LVRS (Re-LVRS) in patients no longer benefiting from their initial LVRS. METHODS Between June 2002 and December 2013, 22 patients (9 females) with advanced emphysema underwent Re-LVRS at a median of 60 months (25–196) after their initial LVRS. While initial LVRS was performed thoracoscopically as a bilateral procedure, Re-LVRS was performed unilaterally by a video-assisted thoracoscopic technique in 19 patients and, due to adhesions, by thoracotomy in 3 patients. Pulmonary function test (PFT) was performed at 3 and 12 months postoperatively. RESULTS Lung function at Re-LVRS was similar to that prior to the first LVRS. The 90-day mortality rate was 0%. The first patient died 15 months postoperatively. The median hospitalization time after Re-LVRS was significantly longer compared with the initial LVRS [14 days, interquartile range (IQR): 11–19, vs 9 days, IQR: 8–14; P = 0.017]. The most frequent complication was prolonged air leak with a median drainage time of 11 days (IQR: 6–13); reoperations due to persistent air leak were necessary in 7 patients (32%). Five patients (23%) had no complications. Lung function and Medical Research Council (MRC) score improved significantly for up to 12 months after Re-LVRS, with results similar to those after initial bilateral LVRS. The average increase in the forced expiratory volume in 1 s (FEV1) was 25% (a 7% increase over the predicted value or 0.18 l) at 3 months, and the mean reduction in hyperinflation, assessed by relative decrease in RV/TLC (residual volume/total lung capacity), was 12% at 3 months (a decrease of 8% in absolute ratios). The mean MRC breathlessness score decreased significantly after 3 months (from 3.7 to 2.2). CONCLUSIONS Re-LVRS can be performed successfully in carefully selected patients as a palliative treatment. It may be performed as a bridge to transplantation or in patients with newly diagnosed intrapulmonary nodules or during elective cardiac surgery. Morbidity is acceptable and outcomes may be satisfactory with significantly improved lung function and reduced dyspnoea for at least 12 months postoperatively.

OBJECTIVES: Lobar lung transplantation is an option that provides the possibility of transplanting an urgent listed recipient of small size with a size-mismatched donor lung by surgically reducing the size of the donor lung. We report our short- and long-term results with bilateral lobar lung transplantation (BLLT) and compare it with the long-term outcomes of our cohort. METHODS: Retrospective analyses of 75 lung transplant recipients who received downsized lungs with a special focus on 23 recipients with BLLT performed since January 2000. Postoperative surgical complications, lung function tests, late complications and survival were analyzed. The decision to perform lobar transplantation was considered during allocation and finally decided prior to implantation. RESULTS: Cystic fibrosis was the most common indication (43.5%) followed by pulmonary fibrosis (35%). Median age at transplantation was 41 (range 13–66) years. Fifteen were females. Nineteen of the transplantations (83%) were done with extracorporeal membrane oxygenation (ECMO) support; 3 of them were already on ECMO prior to transplantation. There was no 30-day or in-hospital mortality. No bronchial complications occurred. The most common early complication was haematothorax (39%), which required surgical intervention. The rate of postoperative atrial arrhythmias was 30%. Forced expiratory volumes in 1 s (% predicted) at 1 and 2 years were 76 ± 23 and 76 ± 22, respectively (mean ± standard deviation). By 2-year follow-up, bronchiolitis obliterans syndrome was documented in 3 patients with a median follow-up of 1457 days. Overall survivals at 1 and 5 years were 82 ± 8 and 64 ± 11%, respectively and were comparable with those of 219 other recipients who received bilateral lung transplantation during the same period (log rank test, P= 0.56). CONCLUSIONS: This study demonstrates that BLLT has short- and long-term outcomes comparable with those of standard bilateral lung transplantation. The limitation of lung transplantation due to size-mismatch, particularly in smaller recipients, could be overcome by utilizing lobar lung transplantation.

The resection of thymic tumours requires completeness and may be technically challenging due to the anatomical proximity of the delicate mediastinal structures. An open approach by sternotomy is still recommended in all cases with locally extended disease. Video-assisted thoracoscopic surgery is feasible, but limited by the two-dimensional vision and the impaired mobility of the instruments. We evaluated the da Vinci® Surgical System for the resection of various mediastinal pathologies, particularly thymomas.Among 105 patients operated on by robotic assisted thoracoscopic surgery (RATS) for mediastinal tumours between 27 August 2004 and 12 July 2011, 20 patients with thymomas were studied prospectively. Of these, 10 males with a median age of 53 years, with a well-circumscribed thymic lesion on computed tomography (CT) and a diameter of6 cm were resected by RATS alone, and selected ones (n = 3), with a diameter of6 cm, underwent a hybrid procedure with a contralateral thoracotomy on the side of the main tumour extension. A regular follow-up with chest CT scans was performed every 6 months.Thymoma resection was complete in all patients. Partial pericardial resection was needed in five and pulmonary resection in two patients. Eighty-five percent of patients had an R0 resection. Histological classifications included thymoma WHO type A (n = 3), AB (n = 8), B1-2 (n = 5) and B3 (n = 4). All B3 thymomas received adjuvant radiotherapy. No intraoperative complications occurred. The median hospitalization time was 5 days (range 2-14 days). There were no local, but two pleural, recurrences. After a median observation time of 26 months, 19 patients (95%) are alive.Well-circumscribed thymomas can be safely and completely resected with the da Vinci® Surgical System with excellent short- and mid-term outcomes. Selected tumours with large diameters may be resectable using a hybrid procedure combining RATS with a thoracotomy.

Objective: Solitary fibrous tumours of the pleura (SFTP) are rare and can histologically be differentiated into benign and malignant forms. The aim of this study is to present new cases, and discuss up-to-date preoperative examinations, the role of video-assisted thoracic surgery and longterm outcome. Methods: Between 1993 and 2006, 27 SFTPs were diagnosed (14 females, mean age SD, 62.3 9.6 years) at our institution. Medicalrecordswere reviewed,and follow-up was obtained byrepeated examinations orcontactwith generalpractitioners.Results:SFTPswere associated with symptoms in 63% of all cases. In the six patients in which positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) was performed preoperatively, malignant lesions were all found to be positive. Complete resection was achieved by video-assisted thoracic surgery in 15 and anterolateral thoracotomy in 12 patients. Mean hospital stay was shorter for patients operated by video-assisted thoracic surgery compared to thoracotomy, 4.5 (range 3—6) versus 7.5 (range 4—25) days, respectively (p < 0.01). Histology revealed 17 benign and 10 malignant SFTP. Mean SD tumour diameter of malignant SFTPs was larger than in benign forms, 11.9 7.1 versus 6.1 3.5 cm, respectively (p < 0.01). Tumour recurrence was recognised in four patients with malignant SFTPs at a median time interval after surgery of 38 (range 6—122) months, two late deaths occurred resulting from tumour recurrences. Conclusions: SFTPs can be treated minimally invasively by video-assisted thoracic surgery with short hospital stay. Large SFTPs with increased FDG-uptake have a high likelihood for malignancy. Long-term follow-up is mandatory in malignant SFTPs because of late recurrences associated with death. # 2007 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.

Objective: To investigate the incidence and management of postoperative complications after neoadjuvant chemotherapy followed by extrapleural pneumonectomy for malignant pleural mesothelioma. Methods: Patients with histologically proven mesothelioma of clinical stages T1—3, N0—2, M0 and considered to be completely resectable received neoadjuvant chemotherapy (cisplatin + gemcitabine or cisplatin + pemetrexed) followed by extrapleural pneumonectomy and postoperative radiotherapy. The incidence and management of postoperative complications in general and of bronchopleural fistula and postpneumonectomy-empyema in particular were analyzed. Univariate analysis was performed toidentifyprognosticfactors[sex,age,sideofoperation,weightloss,smoking,chemotherapy, EORTC-score(EuropeanOrganizationforResearch and Treatment of Cancer-classification) and duration of operation]. Results: Between 1st May 1999 and 15th August 2005, 63 patients underwent complete extrapleural pneumonectomy after neoadjuvant chemotherapy. Postoperative complications were observed in 39 cases (62%) and 2 patients died within 30 days (3.2%). Postpneumonectomy-empyema occurred in 15.8% of the patients (n = 10), six with a bronchopleuralfistula on the right side. All empyemas were treated successfully. Five patients developed chylothorax (7.9%) and four patients had complications due to a patch failure: cardiac herniation (n = 2), restriction of cardiac output (n = 1) or gastric herniation (n = 1). Patients with higher EORTC-score presentedsignificantly morepostoperativecomplications (p = 0.03). A longer duration of surgery tended to be associatedwith a higher incidence of postoperative complications, especially of empyemas. Conclusions: Extrapleural pneumonectomy after neoadjuvant chemotherapy can be performed with mortality rates comparable to standard pneumonectomies. Complications are frequent but can be successfully managed; the EORTC-score seems to be a predictor for postoperative complications.

Background Resection for localized bronchiectasis is a well established therapy. However, there is little information on the role of surgery in non-localized bronchiectasis. Methods Between January 1992 and April 2001, 55 patients without cystic fibrosis underwent resection. Forty-eight patients (mean age 45 (range 23–74) years; 32 women) were available for long-term follow-up. Twenty-five patients underwent resection for localized disease (group 1) and 23 had bronchiectasis in at least two different lobes (group 2). Results Thirty-one of the 48 patients were treated by Video Assisted Thoracoscopic Surgery (VATS) resection. There was no 30-day mortality. Mean duration of hospital stay was 10·9 (range 6–31) days in group 1 and 11·1 (range 5–19) days in group 2. Three of 25 patients in group 1 required reoperation. Only minor complications occurred in group 2 (three patients). Mean follow-up for both groups was 37 (range 6–97) months. Twenty-three of 25 patients in group 1 and 16 of 23 in group 2 reported satisfaction at 6 months after the operation. Recurrent infection was noted in three patients in each group. Haemoptysis recurred in only one patient in group 2. Conclusion The surgical treatment of selected patients with non-localized bronchiectasis was safe and most patients were satisfied with the outcome.

Objectives: Pneumonectomy in chronic pulmonary infection with empyema is associated with a high mortality rate and an increased risk of recurrent empyema. The surgical resection is technically demanding, and successful management continues to be a challenge. Methods: We evaluated a concept which combines (pleuro-)pneumonectomy or completion pneumonectomy with surgical debridement of the pleural cavity and packing with povidine–iodine soaked dressings. The debridement and packing is repeated in the operating theater after 48 h until the chest cavity is macroscopically clean. Finally, the pleural space is obliterated with antibiotic solution. Results: Between February 1997 and October 2000, 11 patients (average age of 59 years, ranging from 25 to 84) with destroyed lung caused by tuberculosis (six), aspergilloma (two), bronchiectasis (one), esophago-pleural fistula (one) or broncho-pleural fistula after lobectomy for bronchial carcinoma (one) and ongoing chronic infection with acute empyema (ten) (25–2500 days between first and definitive therapy) were treated. Pleural culture findings showed Aspergillus in four, Mycobacterium in two, Enterococcus in two, Candida in one and Staphylococcus in one, respectively. The mean number of interventions was 2.9 (2–4). The chest was definitively closed in all patients within 1 week. The mean hospitalization time was 19 days (9–31 days).In the follow-up (10–54 months), there was no recurrence of empyema. One patient (84 years) died at day 31, due to sepsis. Conclusions: Pneumonectomy combined with repeated surgical debridement and antimicrobial therapy enables the successful treatment of chronic pulmonary infection with empyema within a short time period. q 2002 Published by Elsevier Science B.V.
