Abstract:
Objective To investigate the value of endoscopic ultrasonograghy (EUS) in diagnosis and treatment of gastrointestinal neuroendocrine neoplasm (GI-NEN).Methods We retrospectively summarized the clinical data of 44 patients with GI-NEN which were confirmed by pathology and immunohistochemistry,and analyzed the EUS features and the follow-up data of patients who received EUS exam and EUS-assisted endoscopic resection.Results A total of 47 neoplasms were detected in 44 patients,in which 41 were confirmed as neuroendocrine tumors (NET) and 6 were neuroendocrine carcinoma (NEC).Under EUS,all 41 NET appeared as hypoechoic lesions with regular edge and homogeneous echographic pattern,and 18 were originated from mucosal layer and 23 from submucosal layer,which was all confirmed by pathological evaluation.All 41 NET lesions received EUS-assisted endoscopic resection,in which 17 were treated by ESD/EMR and 24 by high frequency electrotomy.Follow-up endoscopy was performed at 3-6 and 12 month after operation,which showed no residual or recurrence.Conclusion EUS may accurately determine the invasion depth of GI-NEN lesions,and provide important information for adapting appropriate treatment strategies,which has highly clinical practice value in the diagnosis and treatment of GI-NEN.
