Clinical outcome of EMR of sporadic, nonampullary, duodenal adenomas: a 10-year retrospective

EMR of most SNADAs can be performed safely and effectively. Increasing size of adenomas was associated with recurrence and bleeding after EMR. No association with recurrence was noted with endoscopic or histologic features. Focal recurrence can be managed with additional endoscopic therapy. Metachronous lesions do not occur. The findings inform directed management and surveillance.
