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: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is the endoscopic method of choice for confirming lung cancer metastasis to mediastinal lymph nodes. Precision is crucial for correct staging and clinical decision-making. Navigation and multimodal imaging can potentially improve EBUS-TBNA efficiency. AIMS: To demonstrate the feasibility of a multimodal image guiding system using electromagnetic navigation for ultrasound bronchoschopy in humans...

Tissue diagnosis of peripheral pulmonary lesions (PPLs) can be challenging. In the past, flexible bronchoscopy was commonly performed for this purpose but its diagnostic yield is suboptimal. This has led to the development of new bronchoscopic modalities such as radial endobronchial ultrasound (R-EBUS), electromagnetic navigation bronchoscopy (ENB) and virtual bronchoscopy (VB). We performed this meta-analysis using data from previously published R-EBUS studies, to determine its diagnostic yield and other performance characteristics...

Endoscopy of the airway is a valuable tool for the evaluation and management of airway disease. It can be used to evaluate many different bronchopulmonary diseases including airway foreign bodies, tumors, infectious and inflammatory conditions, airway stenosis, and bronchopulmonary hemorrhage. Traditionally, options for evaluation were limited to flexible and rigid bronchoscopy. Recently, more sophisticated technology has led to the development of endobronchial ultrasound (EBUS) and electromagnetic navigational bronchoscopy (ENB)...

The field of diagnostic bronchoscopy has been revolutionized in the last decade primarily with the advent of endobronchial ultrasound (EBUS) but also with the addition of multiple different techniques for "guided-bronchoscopy". These advances have had a substantial impact in the management of lung cancer with bronchoscopy now providing both diagnosis and mediastinal staging in a single procedure. EBUS has, in fact, become the first choice for staging of the mediastinum over cervical mediastinoscopy (CM). Although EBUS is now a well-established technique, there are continuous efforts from the scientific community to improve its diagnostic performance, and these will be reviewed in this manuscript...

The advancement of imaging technology has recently facilitated single port minimally-invasive thoracic surgery techniques. Cone-beam computed tomography (CBCT) shows promising results in visualizing the target lesion and its surrounding critical anatomy, with an error of less than 2 mm. The integration of CBCT with the operating room (OR) to form the hybrid OR, provides unparalleled real-time imaging of the patient, which can be used with electromagnetic navigation bronchoscopy to confirm successful navigation and increase procedural accuracy particularly for small peripheral pulmonary targets...

The ability to reach the peripheral pulmonary nodule/mass with bronchoscopy has improved greatly over the past several years with the use of Electromagnetic navigational bronchoscopy; however, many of these lesions are unable to be adequately sampled due to their location outside the bronchial airways. We report the first use of the transbronchial access tool that creates a pathway from the bronchial airway through the lung parenchyma into the targeted lung abnormality.

RATIONALE: Bronchoscopy is commonly used for the diagnosis of suspicious pulmonary nodules discovered on computed tomographic (CT) imaging of the chest. Procedural CT imaging for bronchoscopy planning is often completed weeks to months before the date of a scheduled bronchoscopy, which may not allow discovery of a decrease in nodule size or resolution before the bronchoscopic procedure. OBJECTIVES: To determine whether same-day CT imaging of the chest discovers partial or total resolution of some lung nodules and thereby reduces unnecessary bronchoscopic procedures...

PURPOSE: Electromagnetic navigation bronchoscopy (ENB) provides improved targeting accuracy during transbronchial biopsies of suspicious nodules. The greatest weakness of ENB-based guidance is the registration divergence that exists between the planning CT, acquired days or weeks before the intervention, and the patient on the table on the day of the intervention. Augmenting ENB guidance with real-time tomosynthesis imaging during the intervention could mitigate the divergence and further improve the yield of ENB-guided transbronchial biopsies...

The concept of personalized medicine, which aims to provide patients with targeted therapies while greatly reducing surgical trauma, is gaining popularity among Asian clinicians. Single port video-assisted thoracic surgery (VATS) has rapidly gained popularity in Hong Kong for major lung resections, despite bringing new challenges such as interference between surgical instruments and insertion of the optical source through a single incision. Novel types of endocutters and thoracoscopes can help reduce the difficulties commonly encountered during single-port VATS...

The incidence of pulmonary nodules and lung cancer is rising. Some of this increase in incidence is due to improved pick up by newer imaging modalities. However, the goal is to diagnose these lesion, many of which are located in the periphery, by safe and relatively non-invasive methods. This has led to the emergence of numerous techniques such as electromagnetic navigational bronchoscopy (ENB). Current evidence supports a role for these techniques in the diagnostic pathway. However, numerous factor influence the diagnostic accuracy...

Bronchoscopy to examine peripheral pulmonary lesions is performed using a bronchoscope with an outer diameter of 5-6mm under fluoroscopy, but the diagnostic yield can be insufficient. Problems with transbronchial biopsy include a limited range of bronchoscope insertion, difficulty in guiding a bronchoscope and biopsy instruments to lesions, and insufficient confirmation of the arrival of biopsy instruments at the target lesion; as such, new techniques have been used to overcome these individual problems. Radial-endobronchial ultrasound is used to identify peripheral pulmonary lesions and sampling sites...

BACKGROUND AND OBJECTIVES: Electromagnetic navigation bronchoscopy (ENB) is a promising new technology to increase the diagnostic yield of peripheral lung and mediastinal lesions. Conventional flexible bronchoscopy has a limited yield in peripheral pulmonary lesions, even in experienced hands. Radial endobronchial ultrasound (r-EBUS) with its real-time imaging capability can help to diagnose peripheral pulmonary lesions. In the present study, we aimed to investigate the diagnostic yield and safety of ENB with or without r-EBUS for peripheral lung lesions...

Two peripheral lung nodules suspicious for lung cancer were noted in a patient. Surgical and CT-guided transthoracic needle biopsies were deemed to be high risk given advanced emphysema. The patient received nondiagnostic electromagnetic navigation bronchoscopy and endobronchial ultrasound (EBUS)-guided mediastinal needle biopsies. Repeat bronchoscopy was then performed. The lung nodules were difficult to visualize with both convex probe EBUS and electromagnetic navigation bronchoscopy guidance. Normal saline injection into vicinity of the peripheral lung nodule was then used in hopes of filling airspace with fluid and improving visualization of the lung nodule...

BACKGROUND: Stereotactic body radiation therapy (SBRT) is considered the standard treatment for medically inoperable early stage lung cancer. Bronchoscopy has shown to be effective in obtaining diagnosis of peripheral lung tumors, staging the mediastinum (with endobronchial ultrasound- EBUS-), and placing fiducial markers (FMs). However, the combination of these 3 procedures in a single bronchoscopy has not been studied. The aim of this study is to describe safety and feasibility of performing diagnosis, systematic nodal staging, and placement of FMs in a single bronchoscopic procedure...

BACKGROUND: Pulmonary nodules smaller than 1 cm can be difficult to identify during minimally invasive resection, necessitating conversion to thoracotomy. We hypothesized that localizing nodules with electromagnetic navigation bronchoscopy and marking them with methylene blue would allow minimally invasive resection and reduce conversion to thoracotomy. METHODS: We retrospectively identified all patients who underwent electromagnetic navigation bronchoscopy followed by minimally invasive resection of a pulmonary nodule from 2011 to 2014...

BACKGROUND: Computed tomography scans are increasingly used not only for lung cancer screening but also for staging and evaluation of other cancers. As a result, more patients with pulmonary nodules, many with subcentimeter lesions, are being referred to thoracic surgeons, some with concern for primary lung neoplasm and others with possible metastatic lung lesions. Obtaining a definitive diagnosis of these lesions is difficult. Electromagnetic navigational bronchoscopy (ENB)-guided pleural dye marking followed by thoracoscopic resection is a novel alternative technique for definitive diagnosis...
