title: [Endosonography in the diagnostics of non-epithelial tumors of the esophagus, stomach and duodenum].
abstract: Non-epithelial tumors account for 5% of all neoplasms of the gastrointestinal (GI) tract, most often have no clinical manifestations and they are finding during the endoscopy. Visual inspection and standard method for gable biopsy doesn't let to verify the kind of education.
