Abstract: Background: Gastrointestinal neuroendocrine tumors are rare, usually presented as subepithelial or polypoid tumors. Accurate diagnosis and indication of the type of resection are still challenging. Aim: To determine the effectiveness of echoendoscopy in determining the depth of the lesions (T) identified by endoscopy in order to evaluate surgical and/or endoscopic indication, and to evaluate the results of endoscopic removal in the medium term. Methods: Twenty-seven patients were included, all of whom unde… Show more

“…Limitations of EUS include that differentiating malignant from benign lesions as well as definitive diagnosis still rely on pathological confirmation [5,14]. The endoscopic findings (location, roughness, hardening), when associated with the characteristics detected by EUS (echogenicity, heterogeneity, and depth), are good predictive factors for the differential diagnosis of duodenal subepithelial and polypoid lesions [29]. Tumors can be found in any of the three layers.…”

“…Tumors can be found in any of the three layers. They are slightly hypoechoic and homogeneous, and EUS can help to determine whether a lesion can be safely resected by endoscopy or if surgical intervention is required [29]. Patients with invasion confined to the submucosa can be treated by mucosectomy, while those with evidence of deeper invasion can be treated with a surgical procedure.…”
