Since 1995, video-assisted thoracoscopic oesophagectomy (VATS), according the same surgical principles as the Japanese open surgery, has been completed in 700 patients with oesophageal cancer. Our indication for VATS is (I) no extensive pleural adhesion; (II) no contiguous tumor spread; (III) pulmonary function capable of sustaining single-lung ventilation, and (IV) non radiated patients. We use 4 ports around a 5 cm mini-thoracotomy on 5th intercostal space. We laid emphasis on utilizing magnifying effect of video (5 to 20 magnifications), obtained by positioning the camera at close vicinity to the dissection...

In asthma, bronchoconstriction causes topographically heterogeneous airway narrowing, as measured by 3-dimensional ventilation imaging. Computation modelling suggests that peripheral airway dysfunction is a potential determinant of acute airway narrowing measured by imaging. We hypothesised that the development of low ventilation regions measured topographically by 3-dimensional imaging after bronchoconstriction is predicted by peripheral airway function. Fourteen (14) asthmatic subjects underwent ventilation Single Photon Emission Computed Tomography/CT (VSPECT/CT) before and after methacholine challenge...

We aimed to investigate whether the lung-to-thorax transverse area ratio (LTR) immediately before birth is of diagnostic value for the prediction of postnatal short-term outcomes in cases of isolated left-sided congenital diaphragmatic hernia (CDH). We retrospectively reviewed the cases of fetal isolated left-sided CDH managed at our institution between April 2008 and July 2016. We divided the patients into 2 groups based on LTR immediately before birth, using a cut-off value of 0.08. We compared the proportions of subjects within the 2 groups who survived until discharge using Fisher's exact test...

The broad application of low-dose computed tomography screening has resulted in the detection of many more cases of early lung cancer than ever before in modern history. Recent advances in the management of early-stage non-small cell lung cancer have focused on making therapy less traumatic, enhancing recovery, and preserving lung function. In this review, we discuss several new modalities associated with minimally invasive surgery for lung cancer. Firstly, less lung parenchyma resection via sublobar resection has become an acceptable alternative to lobectomy in patients with tumors less than 2 cm in size or with poor cardiopulmonary reserve...

Small airways represent the key factor of chronic obstructive pulmonary disease (COPD) pathophysiology. The effect of different classes of bronchodilators on small airways is still poorly understood and difficult to assess. Hence, the acute effects of tiotropium (18 µg) and indacaterol (150 µg) on closing volume (CV) and ventilation inhomogeneity were investigated and compared in 51 stable patients (mean age (SD): 70±7 years; 82% males) with moderate to very severe COPD. Patients underwent body-plethysmography, arterial blood gas-analysis, tidal expiratory flow limitation (EFL), dyspnea assessment, and simultaneous recording of single breath nitrogen test (SBN) and transpulmonary pressure-volume curve (PL-V), before and one hour after drug administration...

BACKGROUND: In children, necrotizing pneumonia (NP) is an uncommon, severe complication of pneumonia. It is characterized by destruction of the underlying lung parenchyma resulting in multiple small, thin-walled cavities and is often accompanied by empyema and bronchopleural fistulae. REVIEW: NP in children was first reported in children in 1994, and since then there has been a gradual increase in cases, which is partially explained by greater physician awareness and use of contrast computed tomography (CT) scans, and by temporal changes in circulating respiratory pathogens and antibiotic prescribing...

Electrical impedance tomography (EIT) is a promising imaging technique for bedside monitoring of lung function. It is easily applicable, cheap and requires no ionizing radiation, but clinical interpretation of EIT-images is still not standardized. One of the reasons for this is the ill-posed nature of EIT, allowing a range of possible images to be produced-rather than a single explicit solution. Thus, to further advance the EIT technology for clinical application, thorough examinations of EIT-image reconstruction settings-i...

BACKGROUND: In the past, minimally invasive cardiac surgery (MICS)- coronary artery bypass graft surgery (CABG) alternatives have been introduced that dramatically reduce the invasiveness of standard operative procedures while still showing excellent clinical outcomes. However, in patients with high morbidity, reduced lung function impeding single-lung ventilation is one of the major concerns for MICS-CABG procedures, although those patients might reap the largest benefit from a procedure of reduced invasiveness...

Quantitative lung computed tomographic (CT) analysis yields objective data regarding lung aeration but is currently not used in clinical routine primarily because of the labor-intensive process of manual CT segmentation. Automatic lung segmentation could help to shorten processing times significantly. In this study, we assessed bias and precision of lung CT analysis using automatic segmentation compared with manual segmentation. In this monocentric clinical study, 10 mechanically ventilated patients with mild to moderate acute respiratory distress syndrome were included who had received lung CT scans at 5- and 45-mbar airway pressure during a prior study...

Bronchogenic cyst, a benign congenital cystic lesion of the lung, is a rare cause of respiratory distress in children comprising 7.5% of all mediastinal masses. A thorough preoperative evaluation is crucial to plan for definitive intra- and post-operative management. All patients should be thoroughly evaluated for the presence of compression, deviation or distortion of airways and great veins. The easiest means of providing one lung ventilation in pediatrics is to intubate the main stem bronchus of the nonoperated lung...

BACKGROUND AND OBJECTIVE: Lung biopsies from patients with hypersensitivity pneumonitis (HP) have demonstrated small airway (SA) involvement, but there is no information concerning SA function in HP, and it is unknown whether pharmacological treatment could modify its function. SA function in patients with chronic HP using ultrasonic pneumography (UPG) and impulse oscillometry (IOS) was explored. We also compared initial results with those obtained after 4 weeks of standardized treatment with azathioprine and prednisone...

BACKGROUND: Lung transplantation is the final life-saving option for patients with pulmonary complications after hematopoietic stem cell transplantation (HSCT). Patients undergoing HSCT for hematologic diseases are thought to be high-risk candidates for lung transplantation; therefore, few lung transplants are performed for these patients, and few studies have been reported. This study aimed to describe the characteristics and outcomes of lung transplantation in patients with pulmonary complications after HSCT...

Objective To investigate the effect-site concentration of remifentanil required to blunt haemodynamic responses during tracheal intubation with a single-lumen tube (SLT) or a double-lumen tube (DLT). Methods Patients scheduled for thoracic surgery requiring one-lung ventilation were randomly allocated to either the SLT or DLT group. All patients received a target-controlled infusion of propofol and a predetermined concentration of remifentanil. Haemodynamic parameters during intubation were recorded. The effect-site concentration of remifentanil was determined using a delayed up-and-down sequential allocation method...

Martin Keszler
Although only a small proportion of full term and late preterm infants require invasive respiratory support, they are not immune from ventilator-associated lung injury. The process of lung damage from mechanical ventilation is multifactorial and cannot be linked to any single variable. Atelectrauma and volutrauma have been identified as the most important and potentially preventable elements of lung injury. Respiratory support strategies for full term and late preterm infants have not been as thoroughly studied as those for preterm infants; consequently, a strong evidence base on which to make recommendations is lacking...

BACKGROUND: At birth, infants' lungs are fluid-filled. For newborns to have a successful transition, this fluid must be replaced by air to enable effective breathing. Some infants are judged to have inadequate breathing at birth and are resuscitated with positive pressure ventilation (PPV). Giving prolonged (sustained) inflations at the start of PPV may help clear lung fluid and establish gas volume within the lungs. OBJECTIVES: To assess the efficacy of an initial sustained (> 1 second duration) lung inflation versus standard inflations (≤ 1 second) in newly born infants receiving resuscitation with intermittent PPV...
