Endoscopic ultrasound: Current applications to approach gastrointestinal solid tumors

Abstract

Endosonography is a diagnostic method that has revolutionized the way to approach patients with tumors in the gastrointestinal tract and other extra-digestive organs and structures. Currently, it is a method of choice to assess subepithelial lesions of the gastrointestinal tract and to classify gastrointestinal tumors in the esophagus, stomach, rectum, and pancreas. Therefore, this literature review presents evidence on the classical indications of endosonography, as well as current applications to approach gastrointestinal tumors.
