Core Tip

Core tip: The standard treatment for superficial non-ampullary duodenal epithelial tumors (SNADETs) is controversial. We conducted a multi-center retrospective study, which aimed to compare the treatment outcomes of endoscopic mucosal resection (EMR) with those of endoscopic submucosal dissection for SNADETs by propensity score matching analysis. Twenty-eight patients were matched in each group. EMR achieved shorter procedure time and hospital stay than endoscopic submucosal dissection without any significant differences in curability and safety. Therefore, EMR for SNADETs has an advantage in total medical costs of endoscopic treatment.
