The survival in the segmentectomy group was not inferior to patients treated with lobectomy. In conclusion, the current meta-analysis disclosed that segmentectomies produce similar survival compared to lobectomy for patients with stage I NSCLC. To establish the role of segmentectomy in early NSCLC, more evidence is needed, in particular, a large numbered, prospective, randomised trials, which should dissolve the uncertainties and the questions raised by retrospective data.
Our preliminary data show that BIONOTE technology may be used to reduce false-positive rates resulting from lung cancer screening with low-dose computed tomography in a cost-effective fashion. The model will be tested on a larger number of patients to confirm the reliability of these results.
A systematic review of English and non-English articles using OVID MEDLINE (1980-2014) was performed to evaluate the potential value of prophylactic ligation of the thoracic duct in preventing chylous leakage after oesophagectomy for cancer. Search terms included [Oesophagectomy OR esophagectomy] AND [chylothorax] AND [thoracic duct ligation]. Only those papers that directly compared the incidence of chylothorax in patients who underwent prophylactic ligation [ligation group (LG)] with that in those who had conservative treatment were selected [preservation group (PG)]; all the articles presenting original data and supplying sufficient information on the chylothorax rate after oesophagectomy were included. Independent extraction of articles was performed by two authors using predefined data fields, including study quality indicators. The PRISMA guidelines were carefully adhered to. A total of 5254 subjects were included in the 7 clinical studies examined into the current meta-analysis. Of these, 2179 patients underwent prophylactic ligature of the thoracic duct (LG group) and 3075 had preservation of the thoracic duct (PG group). A significant difference in terms of chylothorax rate [odd ratios (ORs) 0.47 in favour of LG, 95% confidence interval (CI) 0.27-0.80] was noted between the LG group and the PG group. According to our meta-analysis and taking into account-specific caveats, prophylactic ligation of the thoracic duct could be considered as an effective preventative measure to reduce the incidence of postoperative chylothorax.
The electronic nose (e-nose) is a promising technology as a useful addition to the currently available modalities to achieve lung cancer diagnosis. The e-nose can assess the volatile organic compounds detected in the breath and derived from the cellular metabolism. Volatile organic compounds can be analyzed to identify the individual chemical elements as well as their pattern of expression to reproduce a sensorial combination similar to a fingerprint (breathprint). The e-nose can be used alone, mimicking the combinatorial selectivity of the human olfactory system, or as part of a multisensorial platform. This review analyzes the progress made by investigators interested in this technology as well as the perspectives for its future utilization.
Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracic surgery (c-VATS) and post-operative air-leaks prevention still represents an important challenge.Usually, hemostasis is often difficult and unsafe when the VATS approach is performed and the potential role of bipolar sealing devices is still undefined, as proven by limited experiences reported in the literature.By introducing endostaplers in VATS surgery, it was possible to perform safe thoracoscopic resections of lung. On the other hand, several diathermy techniques have been proposed to reduce intraoperative blood loss in surgery. In particular, standard bipolar technology has proven to effect coagulation in small vessels.The aim of this study is to compare bipolar electro thermal devices to endostapler in VATS lung resections concerning intraoperative bleeding and post-operative air leaks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
