Abstract: Objective:To investigate the safety and reliability of endoscopic mucosal resection (EMR) in the treatment of gastrointestinal neuroendocrine tumors (GI-NETs) with a diameter of ≤10mm.Methods:From February 2015 to June 2019, 40 cases of gastrointestinal neuroendocrine tumors with a diameter of ≤10mm underwent EMR in Yantaishan Hospital of Yantai City were retrospectively analyzed to evaluate the safety and reliability of EMR surgery.Results:All 40 cases were performed endoscopically by EMR. The en bloc resection rate and RO resection rate reached 100%. The lesions were all confined to the submucosa and did not infiltrate the muscularis propria. Postoperative pathological classification: NET G1: 35 cases, NET G2 grade: 5 cases, no NET G3 grade cases. There were no complications such as bleeding and perforation during and after the operation. Follow-up: 1 case was lost to follow-up, 1 patient died of other diseases, and the remaining 38 cases were followed up for an average of 27.8 months (5-46 months) without local recurrence or distant metastasis.Conclusion:For well-differentiated G1 and G2 gastrointestinal neuroendocrine tumors with a diameter ≤10mm, EMR is a safe and reliable treatment.
