“…Then, the physicians can track the synchronized probe during bronchoscopic navigation. The probe in the working channel can further pass the tip of the scope into smaller areas, and drive along the map to reach the target [67]. Then, the operator can use RP-EBUS and fluoroscopy for real-time confirmation of the target location before sampling instrument insertion.…”

The increase in incidental discovery of pulmonary nodules has led to more urgent requirement of tissue diagnosis. The peripheral pulmonary nodules are especially challenging for clinicians. There are various modalities for diagnosis and tissue sampling of pulmonary lesions, but most of these modalities have their own limitations. This has led to the development of many advanced technical modalities, which have empowered pulmonologists to reach the periphery of the lung safely and effectively. These techniques include thin/ultrathin bronchoscopes, radial probe endobronchial ultrasound (RP-EBUS), and navigation bronchoscopy—including virtual navigation bronchoscopy (VNB) and electromagnetic navigation bronchoscopy (ENB). Recently, newer technologies—including robotic-assisted bronchoscopy (RAB), cone-beam CT (CBCT), and augmented fluoroscopy (AF)—have been introduced to aid in the navigation to peripheral pulmonary nodules. Technological advances will also enable more precise tissue sampling of smaller peripheral lung nodules for local ablative and other therapies of peripheral lung cancers in the future. However, we still need to overcome the CT-to-body divergence, among other limitations. In this review, our aim is to summarize the recent advances in diagnostic bronchoscopy technology.

“…A steerable probe that can be sensed by the field is loaded into the tip of a flexible bronchoscope and select known points in the tracheobronchial tree are mapped to the virtual lungs to synchronize the images to the EM field. The probe, along with an extendable working channel, can then be advanced past the scope tip into smaller bronchi and drive along the virtual bronchial map to reach the target (9). While some reports indicate ENB is safe and has allowed for better sample yield of peripheral lesions, the technique is highly operator and anatomy dependent.…”

Screening for lung cancer has changed substantially in the past decade since The National Lung Screening Trial. The resultant increased discovery of incidental pulmonary nodules has led to a growth in the number of lesions requiring tissue diagnosis. Bronchoscopy is one main modality used to sample lesions, but peripheral lesions remain challenging for bronchoscopic biopsy. Alternatives have included transthoracic biopsy or operative biopsy, which are more invasive and have a higher morbidity than bronchoscopy. In hopes of developing less invasive diagnostic techniques, technologies have come to assist the bronchoscopist in reaching the outer edges of the lung. Navigational bronchoscopy is able to virtually map the lung and direct the biopsy needle where the scope cannot reach. Robotic bronchoscopy platforms have been developed to provide stability and smaller optics to drive deeper into the bronchial tree. While these new systems have not yet proven better outcomes, they may reduce the need for invasive procedures and be valuable armamentarium in diagnosing and treating lung nodules, especially in the periphery.

“…Small peripheral lesions are frequently more difficult to obtain unless more precise and time-consuming procedures are performed. 3,4 Locating the path to the lesion can be challenging since relying solely on an endoscopic view to approach it, based on the calculated location from an X-ray or computed tomography (CT) scan, has a low success rate. 5 Lesions located at the center of the endobronchial provide the most significant diagnostic output (90%), whereas central endobronchial lesions yield the best diagnostic yield (90%).…”

Introduction: Fiberoptic Bronchoscopy (FOB) has emerged into the method of choice for the detection of lung tumors due to its availability of Adequate cytological and histological samples in the form of broncho-alveolar lavage, bronchial brushings, and bronchial forceps biopsy. This study aims to identify characteristics of bronchoalveolar lavage, aspiration cytology, brushing cytology and forceps cytology of patients suspected with malignancy at the Ulin Regional Hospital in South Kalimantan. Methods: A cross-sectional study was carried out utilizing medical documentation of patients suspested lung cancer from March 2018 to March 2020. Data were grouped by gender, age, type of procedure, and cytology and histopathology findings. Results: The result showed that 67.5% of 117 patients who underwent bronchoscopy had positive results and common histological diagnosis The frequent histopathological conclusion was adenocarcinoma (45.6%) tailed by squamous cell carcinoma (40.55). Forceps bronchoscopy showed a greater positivity rate (75.0%) than bronchoscopy without forceps (63.6%), we also found that by combining BAL and brushing and forceps biopsy, the detection rate of lung malignancy increased to 85.7%, but no correlation between the type of procedure and the likelihood of malignancy was discovered. Conclusions: Forceps bronchoscopy showed a greater positivity rate than bronchoscopy without forceps, but no correlation between the type of procedure and the likelihood of malignancy was discovered in our study.
