Are Endoscopic Ultrasonography Imaging Characteristics Reliable for the Diagnosis of Small Upper Gastrointestinal Subepithelial Lesions?

Abstract

The diagnostic accuracy of EUS imaging is inferior to histopathology in the diagnosis of small upper gastrointestinal subepithelial lesions. Endoluminal resection is a relatively safe and noninvasive modality that not only provides tissue sample for accurate diagnostic interpretation, but also aids in the complete removal of small subepithelial lesions of the upper gastrointestinal tract.
