Thoracic surgery is a field encompassing many diverse operative techniques ranging from open surgeries involving thoracotomies and sternotomies to less invasive operations such as video-assisted thoracoscopic surgery (VATS), endoscopy, and bronchoscopy. The popularity and acceptance of VATS has been increasing over time. Ethical considerations must be used to navigate patient misconceptions of VATS surgery, creating an appropriate informed consent process, determining appropriate patients for VATS, training future thoracic surgeons in VATS, and advancing thoracic surgery innovation...

Hybrid operating room Dyna-computed tomography imaging is increasingly recognized as an important adjunct for management of small pulmonary lesions, either for biopsy or for localization to guide surgical resection. We describe for the first time the combined hybrid operating room Dyna-computed tomography image-guided electromagnetic navigation bronchoscopy dye marking and hookwire localization approach to localize multiple sub-centimetre nodules for video-assisted thoracic surgery metastasectomy. Furthermore, such complex set of procedures can be safely and effectively performed within one operating environment, maximizing work efficiency and minimizing the potential for complications...

Background: Proper manipulation of fibreoptic bronchoscopes is essential for successful tracheal intubation or diagnostic bronchoscopy. Failure of proper navigation and rotation of the fibrescope may lead to difficulties in advancing the fibrescope and might also be responsible for (unnecessary) difficulties and delays in fibreoptic tracheal intubation, with subsequent hypoxaemia. The present study, therefore, aimed to assess the effectiveness of tip rotation in flexible bronchoscopes in different experimental conditions...

Cone-beam computed tomography provides unparalleled real-time imaging of the patient within the hybrid theater, which can be used for simultaneously diagnosing and localizing small pulmonary lesions for resection. Hybrid theater can guide more precise placement of electromagnetic navigation bronchoscopy tools, thereby increasing the diagnostic yield in biopsy procedures while reducing diffusion artifact in dye marking for nodule localization. Furthermore, hook-wires implantation that is widely used to assist in lesion localization for uniportal thoracoscopic surgery can take place in the hybrid suite, eliminating the common complications and discomfort associated with the conventional workflow carried out in the radiology suite...

Electromagnetic navigational bronchoscopy (ENB), one of the methods of navigational bronchoscopy is an advanced diagnostic tool allowing tissue sampling at the lung peripheries which were previously accessible only by computed tomography (CT) guidance or video-assisted thoracoscopic surgery (VATS). We report a 53-year-old man who presented with a cough and dyspnea with constitutional symptoms for one month. CT thorax revealed multiple bilateral peripheral lung nodules and there were no endobronchial lesions on flexible bronchoscopy...

Small (2 cm) peripheral lung lesions and ground glass opacities remain a difficult subset of lung lesions for the diagnosis and management of lung cancer. Surgical biopsy is more difficult for these lesions because intraoperative localization has to be made without the aid of direct visualization or manual palpation. Electromagnetic navigation bronchoscopy can be used in the operating room to identify a small peripheral lesion and marked using an injection of methylene blue, which can be seen on the visceral pleura of the lung...

BACKGROUND: The diagnostic yield of peripheral pulmonary lesions (PPLs) by flexible bronchoscopy (FB) is still insufficient. To improve the diagnostic yield of bronchoscopy, several techniques such as endobronchial ultrasound (EBUS), virtual bronchoscopic navigation (VBN), and rapid on-site evaluation (ROSE) have been examined. The primary purpose of the present study was to evaluate the usefulness of combining EBUS, VBN, and ROSE for diagnosing small PPLs. METHODS: Patients with PPLs 30 mm or less on chest computed tomography (CT) were prospectively enrolled...

Modalities to detect and characterize lung cancer are generally divided into those that are invasive [endobronchial ultrasound (EBUS), esophageal ultrasound (EUS), and electromagnetic navigational bronchoscopy (ENMB)] versus noninvasive [chest radiography (CXR), computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI)]. This chapter describes these modalities, the literature supporting their use, and delineates what tests to use to best evaluate the patient with lung cancer...

We have recently developed a flexible catheter electrode used for bronchoscopic radiofrequency ablation (RFA). Two patients with nonsurgical stage IA peripheral lung cancer and 1 with lung metastasis underwent treatment with flexible catheter RFA utilizing navigation bronchoscopy. Chest computed tomography (CT) and positron emission tomography/CT (PET/CT) were performed before and after RFA to assess the ablation response of the patients. One patient's tumor had no prior PET uptake and therefore no follow-up PET was obtained...

BACKGROUND: Electromagnetic navigational bronchoscopy (ENB) is guided bronchoscopy to pulmonary nodules (PN) that relies on a preprocedural chest CT to create a three-dimensional (3D) virtual airway map. The CT is traditionally done at a full inspiratory breath hold (INSP), but the procedure is performed while the patient tidal breaths, when lung volumes are closer to functional residual capacity. Movement of a PN from INSP to expiration (EXP) has been shown to average 17.6 mm. Therefore, the hypothesis of this study is that preprocedural virtual maps built off a CT closer to physiological lung volumes during bronchoscopy may better represent the actual 3D location of a PN...

OBJECTIVE: In flexible endoscopy techniques, such as bronchoscopy, there is often a challenge visualizing the path from start to target based on preoperative data and accessing these during the procedure. An example of this is visualizing only the inside of central airways in bronchoscopy. Virtual bronchoscopy (VB) does not meet the pulmonologist's need to detect, define and sample the frequent targets outside the bronchial wall. Our aim was to develop and study a new visualization technique for navigated bronchoscopy...

PURPOSE: One of the major challenges in electromagnetic navigated bronchoscopy is the navigation accuracy. An initial rigid image-to-patient registration may not be optimal for the entire lung volume, as the lung tissue anatomy is likely to have shifted since the time of computer tomography (CT) acquisition. The accuracy of the initial rigid registration will also be affected throughout the procedure by breathing, coughing, patient movement and tissue displacements due to pressure from bronchoscopy tools...

BACKGROUND: Navigational bronchoscopy and other imaging modalities have improved the ability to evaluate pulmonary nodules/mass. Many of these lesions are located outside the bronchial airway and are difficult to access even with these devices. The Transbronchial Access Tool (Medtronic, Minneapolis, MN) allows the bronchoscopist to create a pathway from the bronchial airway, across the lung parenchyma, and into the target lesion. We are reporting the feasibility and safety of this new device...

PURPOSE: In bronchoschopy, computer vision systems for navigation assistance are an attractive low-cost solution to guide the endoscopist to target peripheral lesions for biopsy and histological analysis. We propose a decoupled deep learning architecture that projects input frames onto the domain of CT renderings, thus allowing offline training from patient-specific CT data. METHODS: A fully convolutional network architecture is implemented on GPU and tested on a phantom dataset involving 32 video sequences and [Formula: see text]60k frames with aligned ground truth and renderings, which is made available as the first public dataset for bronchoscopy navigation...

Andrew D Lerner, David Feller-Kopman
With the greater use of chest CT, the incidental detection of lung nodules is expected to increase. However, because most lung nodules are benign, there is a high demand for minimally invasive procedures that provide valuable diagnostic information while minimizing complications. Recent advances in bronchoscopic technology meet this demand. These advanced technologies include navigational bronchoscopy and radial endobronchial ultrasound (EBUS) for the diagnosis of peripheral lung nodules, and linear EBUS, which has revolutionized the nonoperative nodal staging of lung cancer and provides a complementary option to surgical staging approaches...
