There are many novel technologies that enable complex segmentectomy to be performed. As lung cancer screening becomes more prevalent, patients are increasingly diagnosed with early stage lung cancer, multifocal disease, and second primary tumors. This shift to an earlier clinical presentation combined with advances in technology and an emphasis on minimally invasive techniques have led to the current developments we are now seeing with anatomic segmentectomy. In this paper, we describe the operative technique of an indocyanine green (ICG)-guided video-assisted thoracoscopic surgery (VATS) single basilar segmental resection, augmented with methylene blue dye marker localization via SuperDimension electromagnetic navigational bronchoscopy...

The expanded possibilities to explore the lung deeper with new tools such as electromagnetic navigation bronchoscopy (ENB) or radial probe endobronchial ultrasonography (radial EBUS), combined with miniaturization of traditional local therapies such as radiofrequency ablation (RFA), radiotherapy, cryotherapy or photodynamic therapy, let the bronchoscopists hope for new ways of endoscopic treatments. This challenge could change the practice in the upcoming decades but raise some physical and technical issues...

Electromagnetic navigation bronchoscopy (ENB) is gaining acceptance and popularity amongst bronchoscopists as one of the tools to diagnose pulmonary nodules (PNs). Although the majority of ENBs in earlier studies were performed under general anaesthesia (GA), later reports suggest that the diagnostic yield of ENB under intravenous sedation (IVS) was comparable, and was time saving. ENB under IVS may potentially improve access of the techniques to practitioners and patients. However, it is technically challenging when compared to its performance under GA...

Background: To find small pulmonary nodules or ground grass nodules (GGNs) with video-assisted thoracoscopic surgery (VATS) is very difficult. There are several conventional methods to localize small nodules or GGNs, which require additional radiation exposure and may cause some complications such as pneumothorax or hemothorax. We aimed to evaluate the effectiveness and feasibility of electromagnetic navigational bronchoscopy-guided pulmonary localization in a minimally invasive thoracic surgery field...

We use pulmonary interventional procedures for the diagnosis of pulmonary diseases either for benign or malignant lesions. Flexible bronchoscopy with or without radial endobronchial ultrasound, convex-probe endobronchial ultrasound and electromagnetic navigation are procedures performed in centers with experience in diagnostic pulmonary medicine. The method of sedation and ventilation is very important in order to avoid or handle with success complications. Proper respiration during pulmonary (or other interventional) procedures is a key factor...

BACKGROUND: Intramedullary nail (IMN) fixation improves functional outcomes for the diaphyseal fractures of long bones. However, locking the distal holes of the IMN is challenging. Although several navigation methods have been proposed, an intuitive, radiation-free and accurate navigation method that does not suffer from problems of hand-eye coordination has not yet been described. METHODS: This paper proposes an augmented reality (AR) surgical navigation method with hybrid optical and electromagnetic (EM) tracking for distal IMN interlocking...

The most effective treatment for twin-to-twin transfusion syndrome is laser photocoagulation of the shared vascular anastomoses in the placenta. Vascular connections are extremely challenging to locate due to their caliber and the reduced field-of-view of the fetoscope. Therefore, mosaicking techniques are beneficial to expand the scene, facilitate navigation, and allow vessel photocoagulation decision-making. Local vision-based mosaicking algorithms inherently drift over time due to the use of pairwise transformations...

PURPOSE: Bronchoscopy for peripheral pulmonary lesions continues to present challenges to clinicians. One potential limitation may be the inability to advance conventional bronchoscopes into close proximity of peripheral lesions prior to biopsy. This study was performed to assess the reach of a robotic endoscopic system within human cadaveric lungs compared to conventional thin bronchoscopes. DESCRIPTION: All segmental bronchi (RB1-10, LB1-10) were accessed in two human cadavers using a conventional thin bronchoscope and robotic endoscope of identical outer diameter...

We describe a novel method using electromagnetic navigation bronchoscopy (ENB) without dye marking to perform vectorial localization for an impalpable peripheral lesion in the right lower lobe during diagnostic surgical resection in a 52-year-old woman. After the ENB registration process, the anesthetist changed the single-lumen endotracheal tube to a double-lumen endobronchial tube. Guided by the ENB system, the operator delivered the probe of the locatable guide to the planned site through the right lumen of the endobronchial tube...

Lung nodules are being increasingly detected, particularly with lung cancer screening with low-dose computed tomography. Although the vast majority of lung nodules are benign, many often require tissue diagnosis. Several modalities to obtain diagnostic tissue from peripheral lung nodules are available. Bronchoscopic modalities such as radial ultrasound and electromagnetic navigational bronchoscopy are becoming increasingly used because of their superior safety profile and improving diagnostic yield. Although these modalities continue to become more advanced, newer and complementary technologies appear promising...

Efficient image guidance is the basis for minimally invasive interventions. In comparison with X-ray, computed tomography (CT), or ultrasound imaging, magnetic resonance imaging (MRI) provides the best soft tissue contrast without ionizing radiation and is therefore predestined for procedural control. But MRI is also characterized by spatial constraints, electromagnetic interactions, long imaging times, and resulting workflow issues. Although many technical requirements have been met over the years-most notably magnetic resonance (MR) compatibility of tools, interventional pulse sequences, and powerful processing hardware and software-there is still a large variety of stand-alone devices and systems for specific procedures only...
