Abstract
In this review article, state-of-the-art diagnostic tools and innovative treatments of thymoma and thymic carcinoma (TC) are described with special respect to advanced tumour stages. Complete surgical resection (R0) remains the standard therapeutic approach for almost all a priori resectable mediastinal tumours as defined by preoperative standard computed tomography (CT). If lymphoma or germ-cell tumours are differential diagnostic considerations, biopsy may be indicated. Resection status is the most important prognostic factor in thymoma and TC, followed by tumour stage. Advanced (Masaoka-Koga stage III and IVa) tumours require interdisciplinary therapy decisions based on distinctive findings of preoperative CT scan and ancillary investigations [magnetic resonance imaging (MRI)] to select cases for primary surgery or neoadjuvant strategies with optional secondary resection. In neoadjuvant settings, octreotide scans and histological evaluation of pretherapeutic needle biopsies may help to choose between somatostatin agonist/prednisolone regimens and neoadjuvant chemotherapy as first-line treatment. Finally, a multimodality treatment regime is recommended for advanced and unresectable thymic tumours. In conclusion, advanced stage thymoma and TC should preferably be treated in experienced centres in order to provide all modern diagnostic tools (imaging, histology) and innovative therapy techniques. Systemic and local (hyperthermic intrathoracic chemotherapy) medical treatments together with extended surgical resections have increased the therapeutic options in patients with advanced or recurrent thymoma and TC.

Abstract
Background Radical surgical resection of advanced thymic tumors invading either the heart or great vessels facing towards the heart is uncommonly performed because of the potential morbidity and mortality. To achieve a complete tumor resection, the use of cardiolpulmonary bypass (CPB) support might be necessary. Methods Retrospective analysis of the results in six patients, who underwent radical tumor resection with CBP support. Results Mean age was 46 years (27 to 66 years) and five patients were male. Tumor infiltration of the heart or the great vessels was evident in all patients. Five patients underwent induction therapy. Two patients were operated in complete cardioplegic arrest (antegrade cerebral perfusion: n = 1). Arterial cannulation of the ascending aorta (n = 5) or the femoral artery (n = 1) and venous cannulation of the right atrium (n = 4) or the femoral vein (n = 2) were performed. Resection of the left brachiocephalic vein (n = 6), resection of the superior caval vein (n = 2), the ascending aorta (n = 1) and the complete aortic arch with outgoing branches (n = 1) were performed. A macroscopic complete resection (R0/R1) was achieved in five patients, whereas one patient was resected incompletely (R2). In-hospital mortality was 0 %. Three (50 %) patients needed operative revision (hematothorax: n = 2, chylothorax: n = 1). All patients had a complicated postoperative course and developed respiratory insufficiency. Conclusions Locally advanced thymoma/thymic carcinoma invading the heart or great vessels can be treated with radical surgical resection alongside with increased perioperative morbidity. The usage of CBP improves the chance of complete tumor resection in selected patients and might lead to a prolonged survival.

Abstract
OBJECTIVE Pain after thoracotomy is associated with intense discomfort leading to impaired pulmonary function. DESIGN Prospective, non-randomized trial from April 2009 to September 2011. SETTING Department of Thoracic Surgery, single-center. PARTICIPANTS Thoracic surgical patients. INTERVENTIONS Comparison of thoracic epidural analgesia (TEA) with the On-Q® PainBuster® system after thoracotomy. MEASUREMENTS AND MAIN RESULTS The TEA group (n=30) received TEA with continuous 0.2% ropivacaine at 4 mL-to-8 mL/h, whereas Painbuster® patients (n=32) received 0.75% ropivacaine at 5 mL/h until postoperative day 4 (POD4). Basic and on-demand analgesia were identical in both groups. Pain was measured daily on a numeric analog scale from 0 (no pain) to 10 (worst pain) at rest and at exercise. There were no significant differences regarding demographic and preoperative data between the groups, but PainBuster® patients had a slightly lower relative forced expiratory volume in 1 second (FEV1) (71±20% versus 86±21%; p=0.01). Most common surgical procedures were lobectomies (38.8%) and atypical resections (28.3%) via anterolateral thoracotomy. Most common primary diagnoses were lung cancer (48.3%) and tumor of unknown origin (30%). At POD1, median postoperative pain at rest was 2.1 (1; 2.8) in the TEA group and 2 (1.5; 3.8; p=0.62) in the PainBuster® group. At exercise, median pain was 4.3 (3.5; 3.8) in the TEA group compared to 5.0 (4.0; 6.5; p=0.07). Until POD 5 there were decreases in pain at rest and exercise but without significant differences between the groups. CONCLUSIONS Sufficient analgesia after thoracotomy can be achieved with the intercostal PainBuster® system in patients, who cannot receive TEA.

Abstract
Advanced age is a known risk factor for morbidity and mortality after coronary artery bypass grafting (CABG). Minimized extracorporeal circulation (MECC) has been shown to reduce the negative effects associated with conventional extracorporeal circulation (CECC). This trial assesses the impact of MECC on the outcome of elderly patients undergoing CABG. Eight hundred and seventy-five patients (mean age 78.35 years) underwent isolated CABG using CECC (n=345) or MECC (n=530). The MECC group had a significantly shorter extracorporeal circulation time (ECCT), cross-clamp time and reperfusion time and lower transfusion needs. Postoperatively, these patients required significantly less inotropic support, fewer blood transfusions, less postoperative hemodialysis and developed less delirium compared to CECC patients. In the MECC group, intensive care unit (ICU) stay was significantly shorter and 30-day mortality was significantly reduced [2.6% versus 7.8%; p<0.001]. In conclusion, MECC improves outcome in elderly patients undergoing CABG surgery.

Abstract
BACKGROUND Complex pleural empyema or lung abscesses are either characterised by long-standing treatment (including treatment failure) or by a bad general condition of the patient (multiple morbidity, sepsis). The operative rectification is often associated with increased morbidity and mortality rates in these cases. Traditionally, the therapeutic tendency for such patients was towards primary creation of a thoracic window including open wound treatment, but this was always also associated with a long sickness and restrictions in the quality of life. The intrathoracic vacuum treatment (VAC) offers here entirely new options in the treatment of complicated pleural empyema and lung abscesses. METHOD We present an illustration of our own clinical experience associated with a selective literature research via Medline (keywords: VAC, vacuum-assisted closure, thoracic empyema). RESULTS After the initial successes of the extrathoracic application of the VAC treatment, the procedure was also analysed for its intrathoracic/pleural use to treat pleural empyema and lung abscesses with and without bronchus stump insufficiency. Initially, the use of the intrathoracic VAC treatment was carried out via a thoracic window (with rib resection), later we developed a minimally invasive procedure (Mini-VAC) while relieving the osseous thorax. An additional intrapleural rinsing with antiseptics (Mini-VAC-Instill) is very practical in cases of proven germ populations. The benefits of the Mini-Vac/Mini-VAC-Instill are: immediate secretion suction with quick local cleaning, rapid germ eradication with a small risk of a fresh population, improvement of the expansion behaviour of the lung as well as short treatment times with quick reclosure of the thorax. In addition to many retrospective examinations, there has so far only been one cohort study in which the classic thoracic window was compared with the VAC treatment. The duration of the stomatic situation as well as the long-term survival in the VAC group were better here than those in the non-VAC group. CONCLUSION The intrathoracic VAC treatment (Mini-Vac/Mini-VAC-Instill) is an innovative procedure that promotes wound cleaning and wound healing in complicated pleural empyema and lung abscesses. Due to the benefits of this procedure, including the improvement of the patient's comfort and the quality of life, the procedure has seen a rapid and broad clinical acceptance.

Abstract
INTRODUCTION In Germany no official guidelines exist for a specific perioperative antibiotic prophylaxis (PAP) in thoracic surgery. In this review, data regarding the PAP as well as antibiotic therapy of the postoperative pneumonia (POP) in thoracic surgery are described. METHODS Selective literature researches were carried out in Medline with consideration of the official recommendations of the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) as well as Paul-Ehrlich-Gesellschaft für Chemotherapie e. V. (PEG). RESULTS The PAP is defined as a short and single application of an antibiotic agent preoperatively or during a surgical intervention. A PAP with first-generation or second-generation cephalosporins could significantly reduce the rate of surgical site infections after thoracic surgery. However, these few randomised trials could not demonstrate a distinct effect on the rate of POP and postoperative empyema. The incidence of POP is approximately 20-25 % after major thoracic surgery. Antibiotic therapy of POP should be performed early and be based on antibiotic sensitivity. CONCLUSION Based on the few prospective, randomised studies a single dose of intravenous PAP with a cephalosporin is recommended in thoracic surgery. Therapy of the POP should include general procedures combined with a specific antibiotic therapy according to antibiotic sensitivity.

Abstract
BACKGROUND Despite significant advances in the treatment of thoracic infections, complex lung abscess remains a problem in modern thoracic surgery. We describe the novel application of vacuum-assisted closure for the treatment of a lung abscess. The technical details and preliminary results are reported. METHODS After the initial failed conservative treatment of an abscess, minimally invasive surgical intervention was performed with vacuum-assisted closure. The vacuum sponges were inserted in the abscess cavity at the most proximal point to the pleural surface. The intercostal space of the chest wall above the entering place was secured by a soft tissue retractor. The level of suction was initially set to 100 mm Hg, with a maximum suction of 125 mm Hg. The sponge was changed once on the 3rd postoperative day. RESULTS The abscess cavity was rapidly cleaned and decreased in size. The mini-thoracotomy could be closed on the 9th postoperative day. Closure of the cavity was simple, without any short- or long-term treatment failure. This technique reduced the trauma associated with the procedure. The patient was discharged on the 11th postoperative day. CONCLUSIONS Vacuum-assisted closure systems should be considered for widespread use as an alternative option for the treatment of complicated pulmonary abscess in elderly, debilitated, immunocompromised patients after failed conservative treatment.

Abstract
Background Objective of this study was to evaluate the impact of age on comparative early outcomes after coronary artery bypass graft surgery (CABG) with minimized (MECC) and conventional extracorporeal circulation (CECC). Methods A retrospective age-, gender- and operation-matched cohort analysis between January 2005 and December 2010 with a total of 2274 patients undergoing CABG with MECC (n = 1137; 50%) or CECC was performed. Patients were stratified into 4 groups according to age: <59 years, 60–69 years, 70–79 years, and 80 years of age or older. Outcomes were compared within each age group. Patients with preoperative dialysis were excluded from analysis. Primary endpoint was 30-day mortality. Results Patients treated with CECC had a significantly higher mean logistic EuroSCORE (6.3% vs. 5.0%; p < 0.001), a slightly lower rate of preoperative myocardial infarction (46% vs. 51%; p = 0.01) and a higher rate of impaired renal function (eGFR < 60 mL/min/1.73 m2: 24% vs. 20%; p = 0.01) compared to MECC-patients. Left internal mammary artery was significantly used more often in MECC patients (93% vs. 86%; p < 0.001). Cardiopulmonary bypass and aortic-cross clamping time were significantly lower in the MECC group (p < 0.001). Overall 30-day mortality was significantly higher in patients treated with CECC (4.4% vs. 2.2%; p = 0.002). Within the different age groups mortality rates were not significantly different except for patients aged 60–69 years (4.5% vs. 1.8%; p = 0.03). Postoperative requirement of renal replacement therapy (4% vs. 2.2%; p = 0.01), respiratory insufficiency (9.9% vs. 6.6%; P = 0.004) and incidence of low cardiac output syndrome (3% vs. 1.2%; p = 0.003) were significantly increased in patients with CECC. Multivariate analysis identified age (p = 0.005; 95% CI 1.01 to 1.08; OR 1.05) among other parameters as an independent risk factor, whereas conventional extracorporeal circulation itself did not present as an independent risk factor for 30-day mortality. Conclusions In this matched study sample early outcome was significantly better in patients with MECC compared to CECC, irrespective of age. Prior myocardial infarction estimated GFR < 60 mL and waiving the use of LIMA were independent risk factors for 30-day mortality, which were more present in the CECC group.

Abstract
BACKGROUND Macroscopic cytoreductive surgery and hyperthermic intrathoracic chemotherapy perfusion (HITHOC) is a new multimodal approach for selected patients with primary and secondary pleural tumors, which may provide the patient with better local tumor control and increased overall survival rate. METHODS We present a single-center study including 20 patients undergoing cytoreductive surgery and HITHOC between September 2008 and April 2013 at the University Medical Center Regensburg, Germany. Objective of the study was to describe the perioperative, anaesthetic management with special respect to pain and complication management. RESULTS Anaesthesia during this procedure is characterized by increased intrathoracic airway and central venous pressure, hemodynamic alterations and the risk of systemic hypo- and hyperthermia. Securing an adequate intravascular volume is one of the primary goals to prevent decreased cardiac output as well as pulmonary edema. Transfusion of packed red blood cells (PRBC) was necessary in seven of 20 (35%) patients. Only two patients (10%) showed an impairment of coagulation in postoperative laboratory analysis. Perioperative forced diuresis is recommended to prevent postoperative renal insufficiency. Supplementary thoracic epidural analgesia in 13 patients (65%) showed a significant reduction of post-operative pain compared with peroral administration of opioid and non-opioid analgesics. CONCLUSION This article summarizes important experiences of the anaesthesiological and intensive care management in patients undergoing HITHOC.

Abstract
OBJECTIVES The effects of cisplatin on the lung parenchyma during hyperthermic intrathoracic chemotherapy perfusion have not been analysed in detail. The objective of this study was to evaluate both the concentration and depth of the penetration of cisplatin in human lung tissue after hyperthermic exposure under ex vivo conditions. METHODS This experimental study was approved by the local ethics committee. Twelve patients underwent pulmonary wedge resections after elective thoracic lobectomies were performed (resected lobe), and the lung tissue (approximately 1-2 cm(3)) was incubated (in vitro) with cisplatin (0.05 mg/ml; 60 min, 42°C). Subsequent tissue beds (depth, 0.5 mm; median weight, 70-92 mg) were prepared from the outside to the middle, and the amount of cisplatin per tissue weight was analysed using atomic absorption spectrometry. Afterwards, the penetration of cisplatin depth was calculated and related to the different concentrations per tissue. RESULTS Cisplatin penetrated into the human lung tissue after ex vivo hyperthermic exposure. The median amount of platinum [nmol cisplatin/g lung tissue] decreased significantly (P ≤ 0.05) depending on the penetration depth: 32 nmol/g (1 mm), 20 nmol/g (2 mm) and 6.8 nmol/g (4 mm). The calculated median concentrations of cisplatin (µg/ml) were 2.4 µg/ml (1 mm), 1.4 µg/ml (2 mm) and 0.5 µg/ml (4 mm), respectively. CONCLUSIONS Under ex vivo hyperthermic conditions, cisplatin diffused into human lung tissue. The median penetration depth of the cisplatin was approximately 3-4 mm. The penetration of cisplatin into lung tissue may affect the local therapy of residual tumour cells on the lung surface using hyperthermic intrathoracic chemotherapy perfusion in patients with malignant pleural tumours.

Abstract
Background In cases of intravenous placement failure of the left ventricular (LV) lead for cardiac resynchronisation therapy (CRT) and obliteration of the left pleural space, the alternative approach of transthoracic placement by video-assisted thoracoscopic surgery (VATS) is difficult and not commonly practiced. Methods Here, we present a simple technique for transthoracic introduction of an epicardial LV lead using a wound retractor (ALEXIS®) in a patient with heart failure. This wound retractor enables atraumatic tissue retraction without rib spreading, an optimal direct view in the pleural space for surgical pleurolysis and a high degree of safety for the patient. Results No perioperative complications occurred. The tube drainage was removed on the second postoperative day, and the patient was discharged on the third postoperative day. Conclusions The decided advantage of this new method is the lack of any need for rib spreading using a mechanical retractor. Especially in patients with a history of open-heart surgery (including internal mammary artery bypass grafting and/or revascularisation of the left lateral wall) or known pleural adhesions (e.g., pleuritis or lung operations), the described technique provides a rapid and save access with minimal surgical effort and greater safety.
