Endosonographic evaluation of patients with suspected extraluminal compression or subepithelial lesions during upper gastrointestinal endoscopy

Abstract

Accurate diagnosis of suspected extraluminal compression or subepithelial intramural lesions, particularly in the stomach, requires meticulous evaluation. EUS provides an invasive but effective option. In one-third of cases, suspected extraluminal compression of the esophagus is actually due to a subepithelial intramural lesion.
