Before June 2016, radial EBUS was performed using the CBs (BF-TE2 [outer diameter 5.9 mm], BF-1T 150 [outer diameter 6 mm], or BF-1T 180 [outer diameter 6 mm], Olympus, Japan; FB-19 TV [outer diameter 6.2 mm], Pentax, Japan). If an endobronchial lesion was identified proximal to or at the level of the subsegmental bronchus, it was labeled as central lesion. In this situation, the patient underwent routine endobronchial biopsy and was excluded from the study.
Bf 1t 150
Manufactured by Olympus
Sourced in Japan
The BF-1T 150 is a compact and lightweight binocular microscope manufactured by Olympus. It features a trinocular viewing head, allowing for the attachment of a camera or other imaging device. The microscope is equipped with infinity-corrected optics and provides a magnification range of 40x to 1000x. The BF-1T 150 is designed for routine observation and analysis tasks in various laboratory settings.

cTBNA is being performed at our facility since 2006 while EBUS-TBNA was started in June 2011.[3 (link), 15 (link)] cTBNA procedures were performed by operators under direct supervision of the consultants. The procedure was performed on an outpatient basis till December 2012 under topical anesthesia alone and from January 2013 onwards under topical anesthesia and conscious sedation (intravenous midazolam and pentazocine in doses sufficient to maintain sedation and cough control).[12 (link), 13 (link)] Subjects were administered 0.6 mg atropine and 25 mg promethazine intramuscularly followed by nebulized lignocaine (4% solution) immediately before the procedure. Topical 10% lignocaine was sprayed over the oropharynx augmented with 2% lignocaine solution instilled over the vocal cords and the airways.[16 (link)] Monitoring of pulse rate, respiratory rate and pulse oximetric saturation was performed throughout the procedure.
A flexible bronchoscope (BF-1T20, BF-TE2, BF-1T150 or BF-IT 180, Olympus, Japan; FB-19TV, Pentax, Japan) was used to perform cTBNA, as described previously.[13 (link)] Smears were prepared on glass slides and sent for cytopathological examination and cultures. Rapid on-site cytologic evaluation (ROSE) was not available.

Patients were enrolled in the study after written informed consent. Detailed history including occupation, drug intake, smoking and relevant medical history were recorded. Bronchoscopy was performed under local anesthesia (nebulization with 4% xylocaine + 2% xylocaine instillation through working channel on vocal cords and central airways) and conscious sedation (midazolam and fentanyl as per protocol). Flexible bronchoscope (Olympus BF 1T 150) was used. TBLB was done under C-arm fluoroscopy guidance with biopsy forceps (Olympus FB-19C-1). The selection of lobe/segment for biopsy was based on the disease pattern on HRCT scan of thorax. Upper lobe biopsy was generally avoided because of proximity to pleura and theoretically higher chances of pneumothorax. Middle lobe and lower lobe were sampled in most of the cases. On an average 6-8 biopsies were taken in each patient. Only one lung was sampled to avoid a possibility of bilateral pneumothoraces. Skiagram chest was done one hour after the procedure to rule out pneumothorax. Patients were hospitalized for 24 hrs to monitor for complications.
The demographic profile and histology reports of selected patients were recorded.

The diagnosis of tracheal stenosis was confirmed with flexible bronchoscopy (FB) (Olympus BF1T150, Tokyo, Japan) when clinical and radiologic signs led to the suspicion of tracheal stenosis. The type of stenosis was classified as web-like or complex. The size and length of the stenosis were measured using chest tomography and during FB evaluation. The localization of stenosis was classified as subglottic, one-third of the upper part of the trachea, middle part of the trachea, and one-third lower part of the trachea. The size of the stenosis was classified according to the degree of stenosis of the tracheal lumen in 4 grades as follows: grade I (≤50%), grade II (51%-70%), grade III (>70%), and grade IV (complete obstruction). FB was performed to evaluate the effectiveness of the treatment and during follow-ups, and rigid bronchoscopy (Novotech rigid bronchoscope, Dutau Novotech, Marseille, France) was applied for the dilatation of stenosis. Patients with tracheal stenosis who could not be treated with rigid bronchoscopy were treated by surgery.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
