BACKGROUND: Video-assisted thoracoscopic surgery (VATS) lobectomy has emerged as a safe and effective technique for treating early-stage lung cancer. Novel three-dimensional, high-definition (3D HD) imaging has removed this technical obstacle and is increasingly used in laparoscopic surgery. We compared our initial experience of 3D HD VATS with standard two-dimensional (2D) HD VATS to identify the advantages and disadvantages of 3D HD visualization in VATS. METHODS: The data of consecutive patients diagnosed with lung cancer who underwent 2D or 3D thoracoscopic lobectomy or bilobectomy at the Guangdong Lung Cancer Institute from July 2013 to October 2014 were retrospectively analyzed...

Chest wall invasion is seen in 5% to 8% of patients presenting with lung cancer. We report a case of complete resection of a 14 cm × 9 cm pT3N0M0 squamous cell carcinoma arising from the right lower lobe and invading the lower chest wall posteriorly, in a 75 years old male, via a hybrid thoracoscopic [video-assisted thoracoscopic surgery (VATS)] approach. Following conventional VATS lobectomy, a targeted 10 cm incision was performed to allow wide resection of the 7(th) to 10(th) ribs and 6(th) to 9(th) transverse processes, with the defect being subsequently reconstructed with a composite rigid prosthesis...

VATS lobectomy is a safe and effective treatment strategy for operable stage I and II lung cancer. It has a similar five-year survival compared to open lobectomy (thoracotomy). VATS lobectomy is associated with less postoperative complications and shorter hospital length of stay when compared to lobectomy by thoracotomy. VATS lobectomy has not been widely adopted by the thoracic surgical community, in part, due to technical reasons. Pulmonary artery branch manipulation in VATS lobectomy is one of the most critical parts of the procedure, especially when endostaplers are used for ligation and division of the vessel...

The feasibility of extending the VATS approach to locally advanced NSCLC has been described with good clinical outcome. These complex resections are still technically challenging and patient safety must remain the highest priority. In this article, we describe our routine VATS approach for left upper lobectomy in proximal, locally advanced lesions. Both surgical and anaesthesiology teams are trained during simulation sessions to respond rapidly in case of urgent thoracotomy. Encircling arterial and venous vessels allow control of inadvertent bleeding during difficult dissection...

INTRODUCTION: Quantitative and accurate measurements of fat and muscle in the body are important for prevention and diagnosis of diseases related to obesity and muscle degeneration. Manually segmenting muscle and fat compartments in MR body-images is laborious and time-consuming, hindering implementation in large cohorts. In the present study, the feasibility and success-rate of a Dixon-based MR scan followed by an intensity-normalised, non-rigid, multi-atlas based segmentation was investigated in a cohort of 3,000 subjects...

Trocars used during video-assisted thoracic surgery (VATS) present some technical disadvantages due to their rigid structure. We propose the use of an extra-small wound retractor system, designed for general surgery, as alternative to rigid trocar for camera port during VATS. In our experience the wound retractor presents 5 objective advantages: reduces intercostal nerve compression and skin injuries, improves the camera maneuverability, does not displace during operation, and protects the camera by any small parietal bleeding...

The uniportal approach for major pulmonary resections began in 2010 with the first case being performed by González-Rivas and colleagues in La Coruña. Since then a number of teams around the world had being performing hundreds of cases, applying it to more advance and complex cases recently. The technique has been reported to be feasible and reliable with similar results to that obtained in early stage lung cancer lobectomies. The case presented in this article is an example of an extreme condition: very obese patient, strong adhesions, fused lower lobe to the diaphragm and enlarged inflammatory adenopathies that made the procedure very technically challenging...

The reprogramming of cellular memory in specific cell types, and in visceral adipocytes in particular, appears to be a fundamental aspect of obesity and its related negative health outcomes. We explored the hypothesis that adipose tissue contains epigenetically distinct subpopulations of adipocytes that are differentially potentiated to record cellular memories of their environment. Adipocytes are large, fragile, and technically difficult to efficiently isolate and fractionate. We developed fluorescence nuclear cytometry (FNC) and fluorescence activated nuclear sorting (FANS) of cellular nuclei from visceral adipose tissue (VAT) using the levels of the pan-adipocyte protein, peroxisome proliferator-activated receptor gamma-2 (PPARg2), to distinguish classes of PPARg2-Positive (PPARg2-Pos) adipocyte nuclei from PPARg2-Negative (PPARg2-Neg) leukocyte and endothelial cell nuclei...

Single incision video-assisted thoracic surgery (VATS), better known as uniportal VATS, has taken the world of thoracic surgery by storm over the previous few years. Through advances in techniques and technology, surgeons have been able to perform increasingly complex thoracic procedures utilizing a single small incision, hence avoiding the inherent morbidity of the standard open thoracotomy. This was a natural extension of what most recognize as the standard of care for early stage lung cancer, the VATS lobectomy, generally performed through a three- or four-incision technique...
