Role of lung point navigation bronchoscopy in diagnosis of peripheral pulmonary lesions

Background
Cancer of the lung is the leading cause of mortality worldwide. There is a continuing problem to treat patients with pulmonary lesions in the peripheral lung. Technology like virtual bronchoscopic imaging is based on assisted-computed tomography pictures that lead the bronchoscopist to the target peripheral lesion.


Objectives
The purpose of this research was to evaluate the safety and effectiveness of the lung point navigation system in the identification of peripheral pulmonary lesions.


Patients and methods
A total of 20 patients took part in this cross-sectional investigation, which used analytical methods. Finally, tissue samples from peripheral pulmonary lesions were collected using virtual bronchoscopic navigation.


Results
Overall, 90% of the cases analyzed were correctly diagnosed using lung point navigation, whereas 10% of the cases were incorrectly diagnosed. The lesion was on average 22.4 mm×23 mm in size, 17.2 mm away from the costal border, and 102.5 mm away from the diaphragm. The average navigation time was 7.4 min, whereas the average planning time was 5 min, and the overall examination duration was 31 min.


Conclusion
The navigation bronchoscopic method is a promising innovation in the field of lung disease diagnostics. Cost, operational skills, and the learning curve have all conspired to keep it from being widely used thus far.
