Efficacy and safety of modified endoscopic mucosal resection for rectal neuroendocrine tumors: a meta-analysis

摘要

Purpose Rectal neuroendocrine tumors are rare with good prognosis. Several endoscopic methods such as endoscopic polypectomy, endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR), and modified endoscopic mucosal resection (m-EMR) are used in the treatment of rectal neuroendocrine tumors. Although m-EMR is derived from traditional EMR, it has not been widely used in clinical practice. In this study, we compared the efficacy and safety of EMR and m-EMR in the treatment of rectal neuroendocrine tumors by performing a meta-analysis.
