Superdimension bronchoscopy

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) and robotic-assisted bronchoscopy (RAB) systems are used for pulmonary lesion sampling, and utilize a pre-procedural CT scan where an airway, or "bronchus sign", is used to map a pathway to the target lesion. However, up to 40% of pre-procedural CT's lack a "bronchus sign" partially due to surrounding emphysema or limitation in CT resolution. Recognizing that the branches of the pulmonary artery, lymphatics, and airways are often present together as the bronchovascular bundle, we postulate that a branch of the pulmonary artery ("artery sign") could be used for pathway mapping during navigation bronchoscopy when a "bronchus sign" is absent...

Bronchoscopic biopsy results for indeterminate pulmonary nodules remain suboptimal. Electromagnetic navigation bronchoscopy (ENB) coupled with cone beam computed tomography (CBCT) for confirmation has the potential to improve diagnostic yield. We present our experience using this multimodal approach to biopsy 17 indeterminate nodules in 14 consecutive patients from April to August 2021. Demographic information, nodule characteristics, and biopsy results were recorded. Procedures were performed in a hybrid operating room equipped with a Siemens Artis Q bi-plane CBCT (Siemens, Munich, Germany)...

INTRODUCTION: Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive, image-guided approach to access lung lesions for biopsy or localization for treatment. However, no studies have reported prospective 24-month follow-up from a large, multinational, generalizable cohort. This study evaluated ENB safety, diagnostic yield, and usage patterns in an unrestricted, real-world observational design. METHODS: The NAVIGATE single-arm, pragmatic cohort study (NCT02410837) enrolled subjects at 37 academic and community sites in seven countries with prospective 24-month follow-up...

BACKGROUND: Transbronchial cryobiopsies has become increasingly important in the diagnostic workup for interstitial lung diseases. The rate of complications and mortality are low compared to surgical lung biopsies, but the diagnostic yield is not as high. The reason for the lower diagnostic yield could in some cases be explained by biopsies taken too centrally or in less affected areas. In this pilot study we examined the feasibility of using the electromagnetic navigation system, superDimension (SD), when performing cryobiopsies to increase the diagnostic yield...

BACKGROUND: The diagnostic yield of electromagnetic navigation bronchoscopy (ENB) is impacted by biopsy tool strategy and rapid on-site evaluation (ROSE) use. This analysis evaluates usage patterns, accuracy, and safety of tool strategy and ROSE in a multicenter study. METHODS: NAVIGATE (NCT02410837) evaluates ENB using the superDimension navigation system (versions 6.3 to 7.1). The 1-year analysis included 1215 prospectively enrolled subjects at 29 United States sites...

Preoperative image-guided localization of lung nodules is necessary for successful intraoperative localization and resection. However, current localization techniques carry significant intraoperative disadvantages for surgeons. Articles were selected through multiple search engines using key search terms and reviewed to compare results, outcomes, advantages, limitations, and complications of various localization methods. Current methods utilize microcoils, hookwires, contrast media, dyes, cyanoacrylate, radiotracers, or fluorescence tracers, which are associated with many intraoperative disadvantages even when paired with other imaging modalities including computed tomography and bronchoscopy techniques...

BACKGROUND: Recent advances in imaging modalities and recommended low-dose computed tomography screening programs have made it easier to diagnose early lung cancer. However, the diagnosis of small ground-glass nodules (GGNs) has been problematic due to inappropriate specimen procurement and failure of conventional percutaneous core needle biopsy. Thus, we aimed to evaluate the usefulness of electromagnetic navigation bronchoscopy (ENB)-guided video-assisted lung resection for not only the diagnosis but also treatment of GGNs...

BACKGROUND: Bronchoscopy is a useful tool for the diagnosis of lesions near central airways; however, the diagnostic accuracy of these procedures for peripheral pulmonary lesions (PPLs) is a matter of ongoing debate. In this setting, electromagnetic navigation bronchoscopy (ENB) is a technique used to navigate and obtain samples from these lesions. This systematic review and meta-analysis aims to explore the sensitivity of ENB in patients with PPLs suspected of lung cancer. RESEARCH QUESTION: In patients with peripheral pulmonary lesion suspected of lung cancer, what is the sensitivity and safety of electromagnetic navigation bronchoscopy compared to surgery or longitudinal follow up? STUDY DESIGN AND METHODS: A comprehensive search of several databases was performed...

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) aids in lung lesion biopsy. However, anatomic divergence between the preprocedural computed tomography (CT) and the actual bronchial anatomy during the procedure can limit localization accuracy. An advanced ENB system has been designed to mitigate CT-to-body divergence using a tomosynthesis-based software algorithm that enhances nodule visibility and allows for intraprocedural local registration. MATERIALS AND METHODS: A prospective, 2-center study was conducted in subjects with single peripheral lung lesions ≥10 mm to assess localization accuracy of the superDimension navigation system with fluoroscopic navigation technology...

Newly advanced diagnostic bronchoscopic procedures, such as electromagnetic navigation bronchoscopy using navigation system technology (superDimension, Medtronic), provides computed tomography referenced and computerized 3-dimensional imaging. To increase accuracy and higher diagnostic biopsy yield, electromagnetic navigation bronchoscopy necessitates special anesthetic and ventilation techniques providing the interventional pulmonologist minimal respiratory lung motion. This anesthetic meets 2 important goals by limiting almost all interference from diaphragmatic and lung movement while allowing the anesthesia provider to achieve hands-free management...

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) is a relatively new method for diagnosing pulmonary lesions in patients with low lung function. Several parameters have been shown to affect diagnostic yield including patient selection. We performed a prospective registration of data on one hundred patients who consecutively underwent electromagnetic navigation bronchoscopy. Selection criteria, patient characteristics, lesion size, distance to pleura, location of the lesion and presence of bronchus sign were registered...

BACKGROUND: Fiducial markers (FMs) help direct stereotactic body radiation therapy (SBRT) and localization for surgical resection in lung cancer management. We report the safety, accuracy, and practice patterns of FM placement utilizing electromagnetic navigation bronchoscopy (ENB). METHODS: NAVIGATE is a global, prospective, multicenter, observational cohort study of ENB using the superDimension™ navigation system. This prospectively collected subgroup analysis presents the patient demographics, procedural characteristics, and 1-month outcomes in patients undergoing ENB-guided FM placement...

INTRODUCTION: Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology that guides endoscopic tools to pulmonary lesions. ENB has been evaluated primarily in small, single-center studies; thus, the diagnostic yield in a generalizable setting is unknown. METHODS: NAVIGATE is a prospective, multicenter, cohort study that evaluated ENB using the superDimension navigation system (Medtronic, Minneapolis, Minnesota). In this United States cohort analysis, 1215 consecutive subjects were enrolled at 29 academic and community sites from April 2015 to August 2016...

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...

Background: With the aid of electromagnetic navigation bronchoscopy (ENB), it has become possible to approach peripheral lung tumors from the airway.

INTRODUCTION: Stereotactic radiotherapy is a high-dose precision technique necessitating accurate target visualization through either cone beam computed tomography (CBCT) or planar imaging with implanted fiducial markers. We have investigated the properties for image guidance using fiducial markers implanted through minimally invasive bronchoscopy. METHODS: Two fiducial marker types were implanted endobronchially in 10 patients undergoing radical radiation treatment for non-small cell lung cancer (eight using Visicoil linear fiducial markers [IBA Dosimetry GmbH, Schwarzenbruck Germany] and two using superDimension and superLock two-band markers [Covidien Inc...

BACKGROUND: Electromagnetic navigation bronchoscopy (ENB) procedures allow physicians to access peripheral lung lesions beyond the reach of conventional bronchoscopy. However, published research is primarily limited to small, single-center studies using previous-generation ENB software. The impact of user experience, patient factors, and lesion/procedural characteristics remains largely unexplored in a large, multicenter study. METHODS/DESIGN: NAVIGATE (Clinical Evaluation of superDimension™ Navigation System for Electromagnetic Navigation Bronchoscopy) is a prospective, multicenter, global, cohort study...

BACKGROUND: Navigational bronchoscopy is utilized to guide biopsies of peripheral lung nodules and place fiducial markers for treatment of limited stage lung cancer with stereotactic body radiotherapy. The type of sedation used for this procedure remains controversial. We performed a retrospective chart review to evaluate the differences of diagnostic yield and overall success of the procedure based on anesthesia type. METHODS: Electromagnetic navigational bronchoscopy was performed using the superDimension software system...

Endoscopic technology has developed markedly with endobronchial ultrasonography (EBUS) having become dramatically widespread over the past 10 years. EBUS-guided transbronchial needle aspiration (EBUS-TBNA) has become an important modality for the mediastinal staging of lung cancer as well as mediastinoscopy. The combination of EBUS with a guide sheath( EBUS-GS) and virtual navigation systems, such as Bf-NAVI, LungPoint, superDimension/Bronchus system, is useful for diagnosis of small peripheral pulmonary lesions...
