Abstract:
Endoscopic ultrasound examination is extremely useful in clarifying potential etiologies of previously enigmatic subepithelial lesions and thick-fold gastropathies. In cases in which the endosonographic appearance is not diagnostic, EUS may aid in obtaining a definitive tissue diagnosis via EUS-guided needle biopsy or by establishing suitability for endoscopic mucosal resection. The evaluation of subepithelial tumors and thickened folds represents an ideal starting point for the novice endosonographer as adequate interpretation is not dependent upon a firm understanding of extraintestinal anatomy.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
