Background: For tracheobronchial diseases, fiberoptic bronchoscopy (FOB) continues to be the gold standard diagnosing technique. It is a rather secure diagnostic and therapeutic method. Because of its excellent sensitivity, fiberoptic bronchoscopy is now the primary diagnostic method for assessing tracheobronchial endoluminal and mucosal diseases. Aim of The Work:To compare virtual bronchoscopy with fiberoptic bronchoscopy as the gold standard tool in diagnosis of cases of hemoptysis and identifying tracheobronchial disorders in patients having clinical and/or radiological reasons for bronchoscopy. Patients and Methods: Patients having hemoptysis with or without CXR or conventional CT abnormalities. Patients with high creatinine level, lactating and pregnant women were excluded from the study. Results: For the research, 50 patients were qualified. There were 50 research participants, 36 of whom were men (72%) and 14 of them were women (28%). The research group's average age was 59, with a standard deviation ± 14. Of the 50 patients, 42 patients had tracheobronchial abnormalities on fiberoptic broncoscopic examination, and virtual bronchoscopic examination confirmed the same abnormality in 37 (88%) patients and did not reveal any abnormality in 5 (12%) patients. an 8 of the 50 patients had no tracheobronchial abnormalities by either diagnostic method. The majority of lesions were obstructive (59.5%), nonobstructive lesions accounted for 23.8%, and partially obstructive lesions accounted for only 16.6%. Regarding the ability to bypass the lesion, out of 42 patients in whom FOB showed a positive lesion, only 15 lesions (35.8%) could be bypassed, while 100% of the lesions detected with VB could be bypassed. Based on the data collected and analysed, the sensitivity of virtual bronchoscopic examination was estimated to be 88% and the specificity was 100%. The PPV and NPV were calculated to be 100% and 61.5%, respectively, and the overall accuracy was estimated to be 90%. Conclusion:Virtual bronchoscopy is an innovative, non-invasive, accurate and uncomplicated diagnostic modality in the diagnosis of tracheobronchial diseases. In particular situations, VB could be the modality of choice, as in the assessment of the airways distal to strictures or stenosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
