Abstract:
Objective To investigate the endoscopic findings and treatment of gastrointestinal neu-roendocrine neoplasms.Methods Endoscopic manifestation and treatment were analyzed retrospectively in 72 patients who were diagnosed as having gastrointestinal neuroendocrine neoplasms by endoscopy and pathol-ogy from May 2011 to December 2014.Results In 72 patients of gastrointestinal NEN,rectum was most commonly involved (48 patients,66.7%),followed by the stomach (16 patients,22.2%),duodenum, esophagus and the ileocecal valve.There were certain features in rectal neuroendocrine neoplasms under endoscopy,mostly manifested by submucosal tumors.But gastric,esophageal,and small intestine NEN man-ifestations showed various forms,without specific typical features,and easy to be misdiagnosed.Some patients diagnosed as having NEN G1 or G2 underwent EMR,ESD or laparoscopy combined with endoscopy resection.Patients diagnosed as having NEN G2 or neuroendocrine carcinoma by pathology received surgical resection,chemotherapy or palliative treatment.All 50 patients underwent endoscopic treatment successful-ly.Perforation occurred in one duodenal bulbar G1 patient during ESD.No bleeding occurred during and after the operation.All patients after treatment were followed up for 15.6 +13.2 months on average with no recurrence or metastasis.Conclusion Manifestations of gastrointestinal neuroendocrine neoplasms vary under endoscopy.Some tumors that locate in mucosa or submucosa with diameter less than 1cm can be resec-ted through EMR or ESD.
