Objective Endobronchial ultrasonography with a guide sheath (EBUS-GS) and virtual bronchoscopic navigation (VBN) improves the diagnostic yield in patients peripheral pulmonary lesions (PPLs). Most previous reports on EBUS-GS-guided transbronchial biopsy (TBB) have included benign malignant diseases. We aimed to determine factors that predicted successful diagnosis by TBB small lung cancer, focus high-resolution computed tomography (HRCT) findings before bronchoscopy. Methods retrospectively...

Guide sheaths (GSs) have been widely used during radial probe endobronchial ultrasound-guided transbronchial biopsy (rEBUS-TBB) of peripheral pulmonary lesions. However, it remains unknown whether a GS enhances the diagnostic yield. We compared yields small lesions between rEBUS-TBB with and without GS.In eight institutions, patients ≤30 mm in diameter were enrolled randomised to undergo (GS group) or (non-GS using 4.0-mm thin bronchoscope, virtual bronchoscopic navigation fluoroscopy. The...

Aim The usefulness and safety of endobronchial ultrasound transbronchial needle aspiration ( EBUS‐TBNA ) have been established recently, but no study has evaluated whether or not aging increases the risk procedure. In present study, we aimed to assess in older patients. Methods medical records database 109 patients who received between 2008 2011 at Nagoya University Hospital, Nagoya, Japan were reviewed retrospectively. All underwent bronchoscopy under light sedation with midazolam. A total...

A 73-year-old woman was diagnosed with pulmonary Mycobacterium avium complex (MAC) infection and received no treatment. Disease progression evident one year later the development of myeloperoxidase-antineutrophil cytoplasmic antibody (ANCA) titers systemic symptoms a fever, polyarthritis, purpura, rapidly progressive glomerulonephritis. Her did not improve antibiotic renal biopsy revealed crescentic glomerulonephritis immunodeposition. According to these findings, she ANCA-associated...

Aim: This study aimed to examine the feasibility and potential benefits of an optical see-through headmounted display (OST-HMD) during real-time ultrasound-guided thoracentesis simulations. Material methods: Six physicians performed a simulation using OST-HMD wireless image transmission system. The time required, puncture needle visibility, pleural fluid collection success rate, head movement procedure smart glass equipped with inertial measurement unit were all recorded compared without...

Objective: The accuracy of rapid on-site evaluation (ROSE) during endobronchial ultrasonography with guide sheath (EBUS-GS) was reported to be approximately 90% for diagnosing small peripheral pulmonary lesions (PPLs). When ROSE EBUS-GS lung cancer is carried out and does not include malignant cells in a position whereby the probe located within or adjacent lesion, best technique overcoming lower diagnostic yield remains unknown. This study aimed evaluate factors affecting positive results...

In patients with interstitial lung disease (ILD), the most frequent locations of cancer are within or near fibrotic lesions. However, diagnostic yield for peripheral pulmonary lesions (PPLs) using endobronchial ultrasonography a guide sheath transbronchial biopsy (EBUS-GS TBB) may be unsatisfactory compared to that PPLs distant from because difficulty in reaching Our objectives were evaluate EBUS-GS TBB according proximity and determine factors affecting PPLs. We retrospectively investigated...

Background: Good adherence to an inhaled medication protocol is necessary for the management of asthma and chronic obstructive pulmonary disease (COPD), several interventions improve have been reported. However, impact patient life changes psychological aspects on treatment motivation obscure. Here, we investigated in inhaler during COVID-19 pandemic how lifestyle affected it.Methods: Seven-hundred sixteen adult patients with COPD who had visited Nagoya University Hospital between 2015 2020...

The occurrence of interstitial lung disease (ILD) with peripheral pulmonary lesions (PPLs) is closely linked to the development cancer. Yet, best diagnostic approach for identifying PPLs in patients ILD remains elusive. This study retrospectively investigated application transbronchial biopsy (TBB) using endobronchial ultrasonography a guide sheath (EBUS-GS) effective and safe diagnosis when compared conventional TBB. sample included consecutive series 19 who underwent TBB or EBUS-GS at...

Pulmonary cryptococcosis with lymph node involvement is relatively rare in immunocompetent patients. We report a case of pulmonary massive mediastinal lymphadenopathy an young patient. In this report, 17-year-old boy presented high-grade fever and persistent cough. Chest X-ray computed tomography showed lymphadenopathy. Endobronchial ultrasound-guided transbronchial needle aspiration revealed histological evidence cryptococcal lymphadenitis. He was treated liposomal amphotericin B plus...

Invasive tracheobronchial aspergillosis (ITBA), a rare form of invasive pulmonary Aspergillus infection (IPA), is predominantly confined to the tree. We herein report case ITBA with severe necrotic pseudomembrane in 57-year-old woman fulminant hepatitis and hemophagocytic syndrome. Bronchoscopic findings revealed widespread pseudomembranous formation trachea bronchi. fumigatus was cultured from bronchial lavage fluid, histological an endobronchial biopsy necrosis hyphae. Although she...

Although endobronchial ultrasound guided transbronchial biopsy (TBB) with a guide sheath (EBUS-GS) is widely used for diagnosis of peripheral pulmonary lesions, the diagnostic contribution cytology (bronchial brushing, bronchial washing and forceps rinse) has not been established. To determine cytological examination to EBUS-GS-TBB, we reviewed medical records patients lung malignancies who had undergone TBB EBUS-GS (EBUS-GS group, n=187) or without (conventional [CTBB] n=197) at Nagoya...

Pulmonary infection is a relatively rare but serious complication of flexible bronchoscopy. The aim this study was to identify the risk factors for pulmonary infectious complications after diagnostic bronchoscopy in patients with lung cancer. We retrospectively analyzed medical records 636 who underwent bronchoscopic biopsy cancer diagnosis between April 2011 and March 2016. compared patients' characteristics, chest computed tomography findings, undertaken procedures, final diagnoses...

Background/need. The increases in reference images and information during bronchoscopy using virtual bronchoscopic navigation (VBN) fluoroscopy has potentially created the need for support a head-mounted display (HMD) because bronchoscopists feel difficulty to see displays that are at distance from them turn their head body various directions. Methodology device description. binocular see-through Moverio BT-35E Smart Glasses can be connected via high-definition multimedia interface have 720p...

Several factors have been reported to affect the diagnostic yield of bronchoscopy with radial endobronchial ultrasound (R-EBUS) for peripheral pulmonary lesions (PPLs). However, it is difficult accurately predict potential each PPL in advance.Our objective was establish a predictive model evaluate before procedure.We retrospectively analysed consecutive patients who underwent R-EBUS between April 2012 and October 2015. We assessed that were successful bronchoscopic diagnosis PPLs using...

There is only limited information on the impact of thin-section computed tomography (TSCT)-determined usual interstitial pneumonia (UIP) pattern in decision-making for resection newly diagnosed lung cancer patients.In this retrospective analysis, data were reviewed from 499 patients who received bronchoscopy between 2010 and 2014. The clinical TSCT-determined UIP process cohort was evaluated.The prevalence rate fibrosis 14.8% (74/499 cases), 86.5% (64/74 cases) which also had emphysema....

Background: The diagnostic yield of peripheral pulmonary lesions (PPLs) through endobronchial ultrasonography with a guide sheath transbronchial biopsy (EBUS-GS TBB) under virtual bronchoscopic navigation is unsatisfactory because radial EBUS probe not always located within the lesion. Transbronchial needle aspiration (GS-TBNA) has potential to overcome lower by improving relationship between and lesion enabling repeated sampling while maintaining location GS near However, there are few data...
