“…Several studies have reported that EBUS-GS with VBN was safe and effective for diagnosing small peripheral lung lesions [22,23]. Furthermore, another study reported that diagnostic yield for small peripheral lung lesions is significantly increased when VBN is added to EBUS-GS [24].…”

“…Indeed, to improve the diagnostic yield for peripheral small nodules we have been using virtual bronchoscopy, a novel CT-based technique that allows a noninvasive intraluminal evaluation of the airways up to about the eighth generation (18)(19)(20). Theoretically, thin-section CT can depict the dimensions of airways as small as approximately 1-2 mm in inner diameter.…”

Rationale: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation caused by emphysema and/or airway narrowing. Computed tomography has been widely used to assess emphysema severity, but less attention has been paid to the assessment of airway disease using computed tomography. Conclusions:We are the first to use three-dimensional computed tomography to demonstrate that airflow limitation in COPD is more closely related to the dimensions of the distal (small) airways than proximal (large) airways.

Transbronchial biopsy of solitary pulmonary nodules (SPNs) is usually performed under fluoroscopic guidance, but success varies widely. Endobronchial ultrasonography (EBUS) may increase the likelihood of success. The ability of EBUS-guided transbronchial biopsy to sample SPNs of ,20 mm in diameter was assessed.All patients seen between June 2004 and August 2007 in whom computed tomography identified a SPN of ,20 mm underwent bronchoscopic general anaesthesia or moderate sedation for a radial EBUS-guided examination. If a typical ultrasonographic picture of solid tissue could be identified, specimens were taken through a catheter with forceps. If the node was not detected within 20 min, the procedure was terminated.Of 100 nodules detected in 100 consecutive patients, 67 (mean diameter 15 mm) were visualised using EBUS and biopsy specimens taken. A diagnosis was established for 46 (46%) patients. If the lesion was visualised by EBUS, the diagnostic success was 69% (46 out of 67). The 33 patients whose nodules could not be sampled underwent surgical biopsy. Pneumothorax occurred in three patients.For SPNs of ,20 mm that can be detected using ultrasound, EBUS-guided transbronchial biopsy is safe and effective.
