AbstractAt present, there are no reports on non-ampullary polyps of the duodenum (NAPDs) in the elderly. The aim of this study was to analyze the clinicopathological features of NAPDs in elderly and non-elderly patients to explore the efficacy and safety of endoscopic mucosal resection (EMR) of NAPDs in the elderly.A total of 110 patients underwent EMR of NAPDs between April 2016 and December 2019. The shape, location, size, postoperative complications, and histopathological types of NAPDs were compared between the elderly group (n = 44) and the non-elderly group (n = 66).Sessile type was the most common form of NAPD in both groups. In the elderly group, the average size of NAPDs was 12.6 ± 3.9 mm. In the non-elderly group, NAPDs had an average size of 10.1 ± 5.8 mm. Complete EMR was performed in both groups. The postoperative complications of EMR did not significantly differ between the 2 groups. Postoperative pathological examination showed that tubular villous adenomas were more common in the elderly group than in the non-elderly group (P = .005), while tubular adenomas were more common in the non-elderly group than in the elderly group (P = .007). Of the 110 patients, 99 completed postoperative follow-up (median follow-up duration, 20.93 months). There were no residual or recurrent lesions.EMR is safe and effective for the treatment of NAPDs in elderly patients.
