LOCALIZATION AND SHAPE OF STENOSES IN PERIPHERAL LUNG CARCINOMA DIAGNOSED BY METHODS OF VB AND FB

Introduction. The study aim to present the diagnostic capabilities of virtual bronchoscopy (VB) and fiberoptic bronchoscopy (FB) for determining the localization and shape of stenoses in patients with peripheral lung carcinoma. Materials and methods. A systemic study was performed on 90 patients, 61 patients of them (67.78%) are men and 29 (32.23%) are women, 44-85 years of age, with endobronchial disease, using the FB and VB methods, over the period 2013-2020. Results. As a result of the study of 220 patients aged 11-83 years (54.36 ± 17.24), in 90 patients after VB (40.91%; 61 men 67.78% and 29 women 32.23%) and in 86 patients after FB (39.09%; 61 men 70.93% and 25 women 29.07%) peripheral lung carcinoma was found. Cases of men diagnosed with VB and FB with peripheral left carcinoma predominate (65.38% and 71.43%, respectively) compared to those in women (34.62% and 28.57%, respectively) and as well as with regard to cases with peripheral right carcinoma. Significant differences in the size of the stenoses were found in both sexes with peripheral carcinoma (U = 4.112, P = 0.0000). Conclusion. VB allows high-quality visualization of stenoses and poststenotic areas that cannot be achieved with FB in peripherally located processes. Through VB peripheral branches of 5-6 order can be reached. VB makes it possible to examine the areas located after the tumour formation.
