Core tip: Endoscopic treatment of duodenal lesions is associated with a high incidence of complications. In particular, duodenal endoscopic submucosal dissection (ESD) is technically difficult. Therefore, the indications for duodenal ESD are not yet to be established. This study aimed to determine an appropriate compartmentalization of duodenal ESD or endoscopic mucosal resection (EMR). ESD was associated with a longer procedure time and a higher incidence of intraprocedural perforation; EMR was associated with a lower rate of complete resection. For early duodenal cancer and neuroendocrine tumors, which require en bloc resection, ESD is preferable if en bloc resection by EMR is difficult, while EMR is sufficient for endoscopic treatment of adenomas.
