High-position single-intercostal two-port video-assisted thoracic surgery (VATS) technique has been used for thoracic diseases. It can effectively avoid postoperative chronic pain compared with the traditional three-port VATS. This study aimed to evaluate the safety and efficacy of high-position single-intercostal two-port video-assisted thoracoscopic lobectomy. ⋯ Lobectomy with a high-position single-intercostal two-port video-assisted thoracoscope for NSCLC is a safe and effective surgical procedure.

Putting artificial intelligence (AI) on the spot: machine learning evaluation of pulmonary nodules.
Lung cancer remains the leading cause of cancer related death world-wide despite advances in treatment. This largely relates to the fact that many of these patients already have advanced diseases at the time of initial diagnosis. ⋯ Deep learning (DL) and convolutional neural networks (CNNs) have shown promising results in pulmonary nodule detection and have also excelled in segmentation and classification of pulmonary nodules. This review aims to provide an overview of progress that has been made in AI recently for pulmonary nodule detection and characterization with the ultimate goal of lung cancer prediction and classification while outlining some of the pitfalls and challenges that remain to bring such advancements to routine clinical use.

Double lumen endotracheal tubes (DLT) are commonly used to provide single lung ventilation during thoracic surgery. A fiberoptic bronchoscope (FOB) is typically used to confirm accurate DLT placement. Accounting for initial purchase, maintenance, repair and cleaning, the use of an FOB can cost as much as $312 per procedure. The VivaSight DLT (VS-DLT) incorporates a built-in camera, which is aimed at reducing FOB use and its associated costs. In this study, we compared the rate of FOB use when intubating using either a VS-DLT or a conventional DLT (c-DLT). ⋯ This study demonstrated a significantly lower rate of FOB use when using a VS-DLT compared to a c-DLT. Placement of the VS-DLT was significantly quicker and malposition during surgery occurred significantly less than with the c-DLT. While intubating with a VS-DLT provides clinical benefits, it may not result in significant cost reductions when compared to a c-DLT.

Many comparative studies of percutaneous balloon mitral valvuloplasty (PBMV) and surgical mitral commissurotomy (SMC) in rheumatic mitral stenosis (MS) were done in the last few decades. With the development of valve repair techniques, various surgical rheumatic valve repair techniques have been applied in clinic, but there is a lack of comparison with PBMV. Our study was designed to compare the perioperative and mid-term outcomes of PBMV and mitral valve repair with "four-step" procedure in the treatment of rheumatic MS. ⋯ For selected patients with rheumatic MS in China, our study shows that there are comparable clinical outcomes in terms of operative, mid-term mortality and complications between PBMV and surgical rMVP with "four-step" procedure. Surgical rMVP shows more advantageous in the correction of valve stenosis and the management of concomitant tricuspid valve lesions and atrial fibrillation (AF).

Uniportal video-assisted thoracoscopic lung sparing tracheo-bronchial and carinal sleeve resections.
Pathology arising from the intrathoracic portion of the trachea (distal trachea), the carina and the main bronchi is usually neoplastic and is mainly treated with surgery. Resection of the intrathoracic portion of the trachea, the carina and the main bronchi for neoplastic lesions does not necessitate lung resection and is traditionally being conducted via open surgery. Video-assisted thoracic surgery (VATS) is witnessing an exponential growth and is the treatment of choice for early-stage non-small cell lung cancer (NSCLC). ⋯ Ventilation is achieved through an endobronchial catheter, inserted into the left main bronchus through which a high-frequency jet ventilation catheter can be also inserted through it. The rationale of applying a minimally invasive technique for the conduction of tracheal and carinal resections, is to exploit its advantages, namely less pain, earlier mobilization and lower morbidity. Uniportal video-assisted resections of the distal trachea, carina and the main bronchi, are safe when conducted by experienced surgical and anesthetic teams.
