“…Innovation in technology has permitted the development of some promising bronchoscopes including those with a thinner diameter or larger working channel than the conventional types. Conventional thin bronchoscopes less than 3.9 mm in external diameter equipped with a 1.2-mm working channel, 18,19 and eventually thin bronchoscopes with a 1.7-mm working channel which allow the use of a thin radial ultrasonic probe have recently been developed. 9,10,20 In a former preliminary study, 9 we demonstrated that the diagnostic yield of EBUS-TBB with the thin bronchoscope for peripheral pulmonary lesions with a mean size of 31 mm was 69%.…”

“…Although the application of a thin bronchoscope in adults is not a novel idea [8,17], only a few small studies have addressed the role of thin bronchoscopy for evaluating localised peripheral pulmonary lesions [4,6,[18][19][20]. The 3.3-mm thin bronchoscope (BF-3C40) was reportedly a useful adjunct to conventional bronchoscopy in the diagnosis of peripheral pulmonary lesions [4].…”

In the present study, the authors evaluated the diagnostic utility of a novel thin bronchoscope with a 1.7-mm working channel for peripheral pulmonary lesions.A total of 118 patients were included in this prospective study. Bronchoscopic examination was performed using a 5.9-mm standard bronchoscope. If no visible endobronchial lesion was found, transbronchial biopsies were performed with 1.5-mm biopsy forceps under fluoroscopic guidance and the bronchus were washed with 10-20 mL of saline solution, using a prototype 3.5-mm thin bronchoscope with a 1.7-mm working channel.Endobronchial lesion was visualised with the standard bronchoscope in 16 patients, and the other 102 patients underwent biopsies with the thin bronchoscope. The mean bronchus levels reached with the standard bronchoscope and the thin bronchoscope were 2.3 and 4.3 generations, respectively. Endobronchial abnormality was revealed with the thin bronchoscope in a further 14 patients. Diagnostic material was obtained in 50 of 68 (74%) patients with malignant disease and 18 of 30 (60%) patients with benign disease. Four patients did not return to follow-up. The diagnostic yield was 57%, even in lesions ,20 mm. There were no major complications.In conclusion, bronchoscopy using a 3.5-mm thin bronchoscope with a 1.7-mm working channel is useful and safe for the diagnosis of peripheral pulmonary lesions.KEYWORDS: Bronchoscopy, lung cancer, peripheral pulmonary lesions, thin bronchoscope, transbronchial biopsy, ultrathin bronchoscope L ocalised peripheral pulmonary lesions are commonly encountered in clinical practice and frequently require tissue diagnoses to project a treatment plan. In the diagnosis of such lesions, bronchoscopy under fluoroscopic guidance has come into wide use as a simple, safe and readily available sampling technique. However, the diagnostic yield of bronchoscopy for peripheral pulmonary lesions has been reported to be limited, so the usefulness of conventional bronchoscopy is controversial [1][2][3].Innovation in technology has permitted the development of some promising bronchoscopes, including those that are thinner than conventional types. A preliminary study suggested that the use of a thin bronchoscope (BF-3C40, 3.3-mm distal end diameter, 1.2-mm working channel diameter; Olympus, Tokyo, Japan) as an adjunct instrument to a standard bronchoscope increases the diagnostic yield by providing an accurate pathway to the peripheral pulmonary lesions [4]. However, transbronchial biopsy (TBB) using currently available biopsy forceps for the 1.2-mm working channel was not performed in that study; the role of the thin bronchoscope as a single method for diagnosing peripheral pulmonary lesions therefore remains unclarified. In addition, several investigators have indicated that the smallcalibre working channel (1.2 mm) of now-available thin bronchoscopes is limited by insufficient specimen collection [5][6][7]. Therefore, the clinical application of thin bronchoscopy for the examination of peripheral pulmonary lesions in adult ...

“…[40][41][42] Bronchial stump granulomas have been associated with the collection of mucous plugs in or around the vicinity of bronchial stumps, sutures, and endobronchial lesions, which have grown Aspergillus species on the culture. [47][48][49][50] When seen bronchoscopically, the fungus ball appears loose within the cavity and exhibits brownish/black color. 44,45 Removal of sutures and obstructing lesions have been reported to solve the problem.…”
