BACKGROUND: Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. METHODS: Three sets of opaque soft copper wires visible under the fluoroscopy (Flu) in the Flu-flexible bronchoscopy (FB) group (n = 24), which determined the three planes of the lesion, were respectively placed firmly on the surface of the chest wall with adhesive tape on the chest wall...

The role of radial-endobronchial ultrasound (R-EBUS) assisted transbronchial biopsy (TBB) for the diagnosis of peripheral pulmonary lesions is well established. However, no study has addressed its safety and value in hemato-oncological patients presenting with non-resolving infiltrates during persistent febrile neutropenia. To assess safety and feasibility of R-EBUS assisted TBB in severe thrombocytopenic and neutropenic patients. Over a period of 18 months, eight patients were assessed with R-EBUS assisted TBB after adequate platelet transfusion...

INTRODUCTION: Airway remodeling in asthma and chronic obstructive pulmonary disease (COPD) results in bronchial wall thickening. Bronchial wall thickness (BWT) can be assessed in high-resolution computed tomography (HRCT) and endobronchial ultrasound (EBUS). AIMS: To compare BWT measured by EBUS and HRCT in patients with mild-to-moderate asthma and COPD, and to evaluate the relationship between the BWT and pulmonary function. METHODS: The study included patients with mild-to-moderate asthma (n = 24), COPD (n = 36) and controls (n = 12)...

BACKGROUND: Peripheral pulmonary lesion (PPL) is a common scenario in patients with chronic obstructive pulmonary disease (COPD) and represents a high risk of malignancy. Severe COPD is associated with higher complication rates following percutaneous biopsy, and routine bronchoscopy. Safety and diagnostic performance of radial endobronchial ultrasound bronchoscopy (R-EBUS) in patients with advanced COPD has not been previously assessed. METHODS: We examined a retrospective cohort of patients with advanced COPD undergoing R-EBUS for the evaluation of PPL...

The aim of this study was to assess the clinical value of radial probe endobronchial ultrasound (RP-EBUS)-guided localization of solitary pulmonary nodules (SPNs) with the combination of ultrathin bronchoscopy and methylene blue prior to video-assisted thoracoscopic surgery (VATS). An ultrathin bronchoscope was used to localize the lesions under RP-EBUS guidance in 48 patients (18 men and 30 women; age range, 41-72 years; mean age, 54 years), who subsequently underwent VATS resection. The lesion size, distance from the parietal pleura, localization time and complications were evaluated...

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...

RATIONALE: Peripheral pulmonary lesions requiring a diagnosis continue to present challenges to clinicians. One significant barrier is the inability to reliably locate peripheral lesions by bronchoscopic approaches. Multiplanar computed tomographic (CT) scan reconstruction is available to most physicians and provides axial, coronal, and sagittal images that may be used to estimate target lesion location and guide bronchoscopists during procedures. OBJECTIVES: This study was performed to evaluate a systematic method of CT-anatomic correlation based on multiplanar reconstruction CT scanning with monoplanar fluoroscopy during bronchoscopy to locate peripheral pulmonary lesions and confirm lesion location, using radial probe endobronchial ultrasound...

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...

BACKGROUND: Radial endobronchial ultrasound with a guide sheath (EBUS-GS) has improved the diagnostic outcomes of peripheral lung lesions. However, to our knowledge, reports on the use of EBUS-GS for diagnosis of cavitary lesions are unavailable. Therefore, this study aimed to assess the effectiveness and safety of EBUS-GS for diagnosis of peripheral cavitary lung lesions (PCLLs). METHODS: This study was a single-institution retrospective review of PCLLs examined by using EBUS-GS between July 2013 and October 2015...

BACKGROUND AND OBJECTIVE: Treatment optimization of non-squamous non-small-cell lung cancers (nonSq-NSCLC) relies on the molecular analysis of the tumour. We aimed to assess the predictive factors of molecular analysis feasibility (MAF) from samples of peripheral nonSq-NSCLC obtained by radial endobronchial ultrasound bronchoscopy (r-EBUS) and 1.5 mm microbiopsy forceps. METHODS: We reviewed data from consecutive peripheral lung nodules sampled with r-EBUS between January 2012 and July 2014 at a single French University Hospital...

Radial probe endobronchial ultrasound (EBUS) helps in the evaluation and sampling of peripheral pulmonary lesions (nodules, masses, consolidation), and has been demonstrated a safer alternative to computed tomography guided procedure, especially in lesions that are away from the chest wall. Although radial probe EBUS has been available for more than two decades, there is no report from the Indian subcontinent. Herein, we describe two cases of peripheral lung lesions that were successfully sampled with the use of radial probe EBUS...

PURPOSE OF REVIEW: Peripheral pulmonary lesions (PPL) are being diagnosed with increasing frequency, especially with the increased use of chest computed tomography (CT). Depending on the location and size, these lesions often present a diagnostic challenge in terms of the low yield of traditional bronchoscopic biopsy techniques or the risks of a percutaneous biopsy approach. RECENT FINDINGS: Over the last several years, several different image-guided bronchoscopy techniques have emerged, including virtual bronchoscopic navigation, electromagnetic navigation bronchoscopy, radial endobronchial ultrasound, and ultrathin bronchoscopy...

BACKGROUND: Rapid on-site evaluation (ROSE) of cytologic specimens is a useful ancillary technique in needle aspiration procedures of pulmonary/mediastinal lesions, but few reports had been carried out to confirm the utility in the diagnosis of peripheral pulmonary lesions (PPLs) by radial probe endobronchial ultrasound (R-EBUS). METHODS: To evaluate the impact of ROSE on the diagnostic yield of R-EBUS for PPLs, we retrospectively analyzed the diagnostic yields of transbronchial biopsy (TBB) or brushing using R-EBUS for patients with PPLs in a tertiary university hospital from December 2012 to December 2014...

BACKGROUND: EBUS guided trans-bronchial biopsy became routine in diagnosis of peripheral pulmonary lesions (PPL). Suction catheter-biopsy is a technique for obtaining a tissue sample from peripheral lung parenchyma. Aim of this study was to evaluate diagnostic efficiency, feasibility and safety of EBUS guided suction catheter-biopsy (SCB) in comparison to trans-bronchial biopsy (TBB) in diagnosis of PPL. The main intention was to demonstrate non-inferiority of the technique over trans-bronchial biopsy, especially when used under navigation of the EBUS...
