PurposeEndoscopic thyroidectomy (ET) requires a proper working space for adequate visualization of anatomical structures and proper instrument manipulation. The purpose of this prospective study was to estimate the feasibility and safety of ET using an anterior chest wall approach without gas insufflation.Materials and MethodsThe working space was created under a direct and endoscopic view through a 3-cm incision on the anterior chest wall. A retracting device was then inserted to establish the working space, and subsequent procedures were performed endoscopically. All data were reviewed using a prospective database.ResultsWe performed 30 ETs in patients with benign thyroid tumors from December 2003 to December 2005. The procedures were completed successfully in 29 patients (mean operative time: 160.6 min; range: 90-345 min). One patient with ET was converted to open thyroidectomy secondary to substernal extension of the tumor. None of the patients developed permanent postoperative hypocalcemia or recurrent laryngeal nerve paralysis. Three patients exhibited some degree of transient recurrent laryngeal nerve palsy.ConclusionThese data suggest that gasless ET using an anterior chest wall approach is safe and feasible in selected patients for treating benign thyroid tumors. This technique may offer good operative working space when performed by surgeons with relatively low-volume ET practices.
Internet of Everything (IoE) is based on Internet of things (IoT), but in addition to IoT, it also includes other technical innovations such as cloud, big data, and IPv6. Cisco defines the age of IoE as ''an era in which unprecedented value is created by real-time interaction with people, processes, data, things, and the rest of the unconnected world, all connected to the Internet.'' In other words, if IoT is technology, IoE can be called ''future lifestyle'' or ''lifestyle innovation'', which will be different from current one through real-time connectivity rather than simply a collection of technologies or technologies.The Wireless Internet of Everything (Wireless-IoE) is a novel paradigm that is shaping the evolution of the future ubiquitous networks. According to the vision underlying the IoE, the next step in increasing the ubiquity of the Internet is to connect smart devices for smart spaces. By providing a highly distributed and ubiquitous network of seamlessly connected heterogeneous smart devices, new services for smart space will be designed to serve anytime, anywhere, and by anyone and anything. ''Smart Devices & Smart Spaces in Wireless Internet of Everything (Wireless-IoE)'' is an important multidisciplinary area with high social and business impact fall under the IoE, including personal healthcare, smart cloud, smart city, smart home, and smart transportation, and it is strongly expected that new applications will emerge once the enabling technologies reach a stable state. However, various studies have been conducted on Wireless-IoE, but there are still many problems to be solved.
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.
