Эндоскопический метод считается ведущим в визуализации  слизистой оболочки  органов верхнего отдела дыхательных путей. Благодаря новым опциям, встроенным в современные видеоэндоскопические системы, имеется возможность определения начальных изменений  в сосудистой  структуре слизистой  оболочки, которые, как известно, могут быть  верными предвестниками развития злокачественного процесса.

NBI-эндоскопия (narrow band imaging – изображение в узком спектре света) является одним из новейших методов оптической  визуализации,  которая  позволяет  усовершенствовать  диагностические  возможности   стандартной  эндоскопии за счет селективного улучшения контрастности кровеносных сосудов. Этот эффект достигается путем изменения стандартного светового  спектра  за счет фильтра, встроенного в источник света, который поглощает  все длины   волн, кроме двух: 412 и 540 нм. Световые волны определенного спектра абсорбируются исключительно гемоглобином. Таким образом, сеть капилляров на поверхности  слизистой оболочки окрашена в коричневый цвет, а венозная сеть подслизистого слоя окрашена  в голубой цвет, что дает возможность очень четко визуализировать их на фоне  однородно   окрашенной   слизистой оболочки.

В статье приведен обзор данных мировой литературы о диагностической эффективности метода NBI-эндоскопии, охватывающий   также возможности  интраоперационного  применения  данной  методики. Также приведены  клинические случаи, на примере которых показаны возможные области применения.

It is generally agreed today that that endoscopy is the main method for the visualization of the mucosa of the upper airdigestive tract.What is more we can see early changings in the vascular structure due to modern technologies that are combined with endoscopy.

NBI (narrow band imaging) endoscopy is one of the most modern optic method that allows to enhance the facilities of standard white light endoscopy. It can be achieved by enhancing of contrast of the vessels. This effect can be gained be means of optical color separation filters that modify the spectral features. The filter is placed in the optical system of the illumination and cuts all wavelengths in illumination except two narrow wavelengths: 415 nm and 540 nm. Narrow band illumination is strongly absorbed by hemoglobin. As a result, capillaries on the mucosal surface are presented in brown on the monitor, and veins in the submucosal surface are displayed in cyan.

In the present  article we propose the world literature review considering  the diagnostic effectiveness of NBI endoscopy. We included available information about perioperative application of this diagnostic method as well. And we proposed several clinical cases.
