Video-assisted thoracoscopic lobectomy with the patient in the semi-prone position: initial experience and benefits of lymph node dissection.
Recently, the prone position has been used for thoracoscopic oesophagectomy for oesophageal cancer because it is known to facilitate mediastinal dissection. We hypothesized that this advantage of the prone position could apply to video-assisted thoracoscopic surgery, which has been commonly performed with the patient in the lateral position. ⋯ To the best of our knowledge, this is the first report that has described video-assisted thoracoscopic lobectomy with the patient in the semi-prone position. Although the number of cases was limited, the results of this study show that the semi-prone position could be attempted especially for right lower lobe lung cancer.

Feasibility of esophageal reconstruction using a pedicled jejunum with intrathoracic esophagojejunostomy in the upper mediastinum for esophageal cancer.
An alternative conduit is needed when the gastric tube cannot be used as an esophageal substitute for reconstruction after esophagectomy. We adopted pedicle jejunal reconstruction with intrathoracic anastomosis in the upper mediastinum under such circumstances. The aim of this study was to evaluate the feasibility of this technique. ⋯ Pedicle jejunal reconstruction with intrathoracic anastomosis can be performed safely under thoracotomy or thoracoscopic surgery when stomach cannot be used as an esophageal substitute after esophagectomy.

ReviewSurgical treatment of nontuberculous mycobacterial lung disease.
While the prevalence of pulmonary tuberculosis has been decreasing, the prevalence of nontuberculous mycobacterial lung disease has been increasing. Unlike tuberculosis, nontuberculous mycobacterial disease is not communicable. However, their indolent nature may result in extensive parenchymal destruction, causing respiratory failure and vulnerability to airway infection. ⋯ The indications for surgery include a poor response to drug therapy, the development of macrolide-resistant disease, or the presence of a significant disease-related complication such as hemoptysis. The surgical procedures of choice are various types of pulmonary resections, including wedge resection, segmentectomy, lobectomy, or pneumonectomy. The reported series have achieved favorable treatment outcomes in surgically treated patients with acceptable morbidity and mortality rates.

ReviewHow to prevent spinal cord injury during endovascular repair of thoracic aortic disease.
The incidence of spinal cord injury in thoracic endovascular aortic repair (TEVAR) has been 3-5 % from recent major papers where sacrifice of the critical intercostal arteries is inevitable by a stent graft. Hemodynamic stability, which depends on a network of blood vessels around the cord is most important not only during but also after stent-graft deployment. High risk factors of spinal cord injury during endovascular aortic repair are (1) coverage of the left subclavian artery, (2) extensive coverage of long segments of the thoracic aorta, (3) prior downstream aortic repair, (4) compromising important intercostal (T8-L1), vertebral, pelvic and hypogastric collaterals, and (5) shaggy aorta. ⋯ For imaging assessment of blood supply to spinal cord including Adamkiewicz artery, prophylactic cerebrospinal fluid drainage is mandatory, and monitoring motor-evoked potential is recommended for high risk factors of spinal cord injury. Mean arterial pressure should be maintained over 90 mmHg after stent-graft placement for a while to prevent delayed spinal cord ischemia in high-risk patients of spinal cord ischemia. Finally, because spinal cord injury during TEVAR is not rare and negligible, perioperative care during TEVAR should be strictly performed according to the protocol proposed by each cardiovascular team.

Early outcomes and hemodynamics after implantation of the Trifecta aortic bioprosthesis.
The Trifecta valve is a recent, newly designed high performance valve, with few studies on the clinical and hemodynamic data. The purpose of this study was to evaluate the early clinical and echocardiographic results of the Trifecta valve. ⋯ The Trifecta aortic bioprosthesis provided satisfactory early outcomes and hemodynamic function.
