The examination of gastric submucosal protruding lesions with endoscopic ultrasound (EUS)

Introduction: The submucosal lesions of the gastrointestinal tract are often discovered during gastroscopy as intact epithelium-covered or exulcerated alterations. They are detected either incidentally or as the cause of gastrointestinal bleeding. Biopsies taken from the surface of the mucosa do not provide meaningful assistance in the characterization of the lesions. Endoscopic ultrasonography (EUS)-guided fine needle aspiration cytology (FNA) has a key role in the diagnosis of theise tumors. Results: In 2013 and 2014, during the EUS examinations of the esophagus, stomach and duodenum, submucosal protruding les…
