We examined the reproducibility of dual-energy x-ray absorptiometry (DXA) visceral adipose tissue (VAT) estimates as well as the impact of pre-assessment diet. In a counterbalanced design, 41 adults received 6 DXA scans, while consuming standardized high- and low-carbohydrate (LC) diets. The impact of pre-assessment diet was examined via repeated-measures analysis of variance and reproducibility of VAT estimates was evaluated by technical error of measurement (TEM) and s.e. of a single determination (SESD)...

Surgery for pulmonary metastasis is performed heterogeneously with regard to surgical approach [open vs. video-assisted thoracoscopic surgery (VATS)] and resection techniques (e.g., laser enucleation, electro-cautery resection, stapling). Complete tumor resection and preservation of lung parenchyma are of upmost importance. This is technically challenging, especially for central lesions close to vascular and bronchial segmental structures. Thus, simple thoracoscopic wedge resections are often not feasible. A VATS lower lobe bisegmentectomy (S7/8) was performed on a 62-year-old patient with a suspicious pulmonary nodule and a history of hemicolectomy for colorectal carcinoma...

Uniportal video-assisted thoracoscopic surgery (VATS) has now evolved into a sophisticated technique that can be used in some of the most complex thoracic procedures; however, this approach to segmentectomy is not standardized, and the surgical procedure varies between surgeons. Here, we describe the use of our uniportal VATS procedure during right upper posterior segmentectomy in a patient with a nodule in the right upper lobe. Subsequent mediastinal lymphadenectomy was performed. The patient has recovered well after surgery...

Diego Gonzalez-Rivas and his colleagues performed the first case for pulmonary major resection by the uniportal approach in 2010. In the following years, more and more expert surgeons developed the uniportal approach and even applied it to very complex cases. Many centers have showed that uniportal video-assisted thoracic surgery (VATS) lobectomy is a safe and feasible technique. The patient presented here is a complex case: The lingular segmental artery was invaded seriously by the tumor and it was difficult to divide it freely, and the pulmonary artery plasty was needed...

BACKGROUND: Pulmonary segmentectomy can be an oncologic equivalent of lobectomy for small non-small cell lung cancer. Uniportal video-assisted thoracoscopic surgery (VATS) has recently showed favorable surgical outcomes, but remains technical demanding, especially in a complex procedure like anatomic segmentectomy. This manuscript demonstrates the surgical techniques for uniportal VATS segmentectomies with the assistance of additional needlescopic instruments. METHODS: Data of 22 consecutive patients who underwent 24 needlescopic-assisted uniportal VATS segmentectomies between December 2016 and June 2017 was analyzed...

It is well known that the "gold standard" procedure for surgically resectable early-stage non-small cell lung cancer (NSCLC), is pulmonary lobectomy. Even though sublobar resections (SLR), particularly segmentectomy, seem attractive as an alternative to lobectomy in early stage lung cancers, they are still debated procedures. The aim of this study is to answer to the question: "Is VATS lung segmentectomy an underused option?" To obtain an answer to this query, the authors carried out a review of the "state of the art" as follows: (I) performing a non-systematic review of the literature; (II) analyzing the review articles published; (III) looking at the ongoing studies, the results of which have not yet published; (IV) scanning the technical aspect of lung segmentectomy...

Over the past 20 years, there have been significant advancements in thoracoscopic surgical techniques as well as in lung cancer screening protocols, which have identified greater numbers of smaller lung tumors (<2 cm) that are more frequently operable and curable. These advancements have led to new interest in the thoracoscopic (VATS) approach to segmentectomy. This article will discuss the outcomes and technical considerations associated with VATS segmentectomy.

Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block...

BACKGROUND: During the period from 1996 to 2016, we have performed 281 thymectomies in patients with various diseases of the thymus. In 179 patients, thymic pathology was associated with autoimmune myasthenia gravis (MG), and, in 108 patients, thymoma was diagnosed. METHODS: The majority of surgeries [254] were performed using video thoracoscopy, 79 of them with an additional cervical approach. The long-term results of video thoracoscopic thymectomies in myasthenic patients were followed up for 1 to 15...

Nowadays, sublobar anatomic resections are gaining momentum as a valid alternative for early stage lung cancer. Despite being technically demanding, anatomic segmentectomies can be performed by uniportal video-assisted thoracic surgery (VATS) approach to combine the benefits of minimally invasiveness with the maximum lung sparing. This procedure can be even more complex if a combined resection of multiple segments from different lobes has to be done. Here we report five cases of combined and unusual segmentectomies done by the same experienced surgeon in high volume institutions to show uniportal VATS is a feasible approach for these complex resections and to share an excellent educational resource...

Video assisted thoracic surgery (VATS) has become a routinely utilized approach to complex procedures of the chest, such as pulmonary resection. It has been associated with decreased postoperative pain, shorter length of stay and lower incidence of complications such as pneumonia. Limitations to this modality may include limited exposure, lack of tactile feedback, and a two-dimensional view of the surgical field. Furthermore, the lack of an open incision may incur technical challenges in preventing and controlling operative misadventures leading to major hemorrhage or other intraoperative emergencies...

Video-assisted thoracic surgery (VATS) allows to treat pulmonary and mediastinal diseases although two-dimensional (2D) imaging can make difficult to estimate the morphological and topographical characteristics of a lesion. Some technical aspects have certainly been corrected with the introduction of robot-assisted thoracic surgery (RATS), although not widespread in less economically developed countries. As an emerging imaging system and technique, 3D VATS is an interesting resource for thoracic surgeons and it may be a proper and valid aid in minimally-invasive surgery, but not an alternative or a compromise to the most expensive robotic technology...

Some series report the use of video-assisted thoracic surgery (VATS) in patients with locally advanced non-small cell lung cancer (NSCLC) but, few studies describe the use of the robotic approach specifically for locally advanced disease. One potential advantage of the robotic approach over traditional VATS is the increased radicality. While the benefit of the robotic approach over open thoracotomy is directly related to reduced surgical trauma and the improved tolerability in fragile patients that have received induction treatment...

Video-assisted thoracoscopic surgery (VATS) has become increasingly accepted, and the thoracic surgeon must be proficient in this technique. Although the advantages of VATS are widely acknowledged, the procedures are technically challenging and may result in catastrophic complications. Thus, the importance of VATS training has long been recognized and various training simulators are available. In this report, we introduce a training method using a new simulator comprising polyvinyl-alcohol (PVA) hydrogel mimicking real human anatomy and texture...

Video-assisted thoracoscopic surgery (VATS) approaches to lobectomy for treatment of early stage non-small cell lung cancer (NSCLC) have generally been accepted to be beneficial. Experience and results for more extensive resections, including thoracoscopic pneumonectomy are limited. Here we report a case with attached videos describing key technical aspects of performing a thoracoscopic left pneumonectomy. This demonstrates the adoption of VATS for tumor pathology requiring pneumonectomy is feasible and can be done safely...

Video-assisted thoracic surgery (VATS) surgery has seen an evolution from multiple ports to uniportal and finally subxiphoid uniportal recently. In traditional VATS surgery, the instruments and the thoracoscope enter the thoracic cavity through two to four operating ports on the lateral chest wall, which can cause chronic pain and chest wall numbness. However single-portal VATS surgery could potentially cause similar problems as the port is placed in between the ribs. In March 2015 Liu et al. reported a VATS bilateral pulmonary metastasectomy and right middle lobectomy via a subxiphoid uniportal technique...
