ABSTRACT

Objective: To evaluate the diagnostic value of endoscopic ultrasonography in gastrointestinal neuroendocrine neoplasms (GI-NENs). Methods: We studied the patients diagnosed with GI-NENs from January 2015 to February 2019 at The First Affiliated Hospital of Xi'an Jiaotong University, and recorded their pathology, endoscopic features and treatment. We analyzed the accuracy of diagnosis GI-NENs by endoscopic ultrasonography, endosonographic characteristics and the choice of surgical methods for different lesions. Results: A total of 33 patients had pathological findings and were treated at our hospital. With pathological diagnosis as the gold standard, the accuracy of endoscopic ultrasonography diagnosis was 90.9%. GI-NENs usually occurred in the rectum and the stomach. Endoscopically, they were spherical or hemispherical, yellow or white and hypoechoic bulging lesions with smooth surface and hard texture, which usually originated from the submucosa. Results: Endoscopic ultrasonography has a great diagnostic value in GI-NENs and it helps make decision on treatment.
