“…EMR is generally safer than ESD and is the preferred method for resecting SNADETs in endoscopic procedures worldwide. Furthermore, underwater EMR (UMER) has been shown to have high efficacy and a high rate of en bloc resection for SNADETs [ 13 ], with various techniques developed to improve UMER success rates [ 14 ]. However, for lesions larger than 20 mm, the possibility of EMR achieving en bloc resection is limited because of the size constraints of mucosa that snares can encapsulate [ 15 ].…”

Endoscopic submucosal dissection (ESD) of superficial non—ampullary duodenal epithelial tumors (SNADETs) is associated with a high rate of en bloc resection and low rate of recurrence. However, in the United States, SNADETs are predominantly managed using endoscopic mucosal resection (EMR) or surgery because the feasibility and safety of duodenal ESD have not yet been established. In this study, we analyzed the outcomes of duodenal ESD for SNADETs. This single—center retrospective study reviewed the data of patients who underwent ESD for SNADETs between June 2018 and August 2023. Baseline patient characteristics, histopathology of the resected lesions, adverse events, and recurrence rates were evaluated. The primary outcome measures were en bloc resection, complications, and recurrence rate. Thirty ESD procedures were performed on 24 patients. All 30 lesions were adenomas, with no cancerous lesions. The en bloc resection rate and R0 resection rates were both 53%. There were no cases of procedure-associated perforation. Post-ESD bleeding was observed in six cases. No ESD—related mortality was observed. The recurrence rate was 14% in 1 year follow up, and 28% the during all follow-up period. ESD is a safe option for SNADET in the United States; however further comparative studies are necessary to determine the optimal procedure for North American populations.
