Thanks to a number of qualitative changes of NLS-diagnostic devices, like metatron 4025 hunter, NLS-graphy potentials were widened to extent unthinkable even few years ago, when CT and MRI had obviously growing advantage in surgical gastroenterology.

    Application of high-frequency sensors during NLS-studies in gastroenterology allowed to move early diagnostics of pathology to a qualitatively new and higher level. By means of spectral-entropic analysis and ultramicroscanning it is possible to diagnose superficial carcinoma of esophagus or stomach, when cancerous cells infiltrate mucous and sub-mucous levels only and initial manifestations of metastases in perioesophageal and periogastric lymph nodes. It is considered that application of high-frequency sensors at three-dimensional visualization ensures determining of depth and length of tumorous infiltration into stomach walls in 93.6% of cases.

    Besides using of high-frequency sensors allows to excel all known methods of polyps and bile papilla cancer diagnostic, at the same time specificity of the method at preoperational diagnostic of choledocholithiasis reaches 94%. And finally, there is information that application of highfrequency sensors allows to visualize concrements not visible even at intraoperational cholengiography.
