Background and Aims: Endoscopic treatment for duodenal neoplasms is associated with a high risk of perforation. This study aimed to determine the feasibility of endoscopic treatment for sporadic nonampullary duodenal adenoma (SNDA). Methods: Consecutive patients undergoing endoscopic treatment for SNDA between January 2005 and December 2015 were included in the study. Clinical characteristics and endoscopic outcomes were analyzed using medical records. Long-term outcome was assessed in patients whose follow-up period was >12 months >1 year. Results: A total of 95 lesions (92 patients) were treated with argon plasma coagulation (APC) ablation (n = 25), endoscopic mucosal resection (EMR, n = 59), or endoscopic submucosal dissection (ESD, n= 11). The median age was 54.9 years, and 63% were male. In patients who underwent EMR and ESD, the en bloc resection rate was 83.1 and 90.0% (p > 0.99); and the complete resection rate was 81.4 and 80% (p > 0.99), respectively. Perforation occurred in 8 patients (8.7%), 4 of whom required surgery. The ESD group showed a significantly higher perforation rate than APC or EMR group (45.5 vs. 0 and 5.1%; p < 0.001). During the median follow-up period of 19 months (range 12–137 months), one patient in the APC ablation group experienced recurrence; no recurrences were seen among EMR and ESD groups. Conclusions: Favorable long-term outcomes indicate that endoscopic treatment is an effective approach for the treatment of SNDA. Considering the high risk of perforation associated with ESD, APC, or EMR may be an acceptable alternative.
