Background: To observe and preliminarily evaluate the efficacy and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in the treatment of non-ampullary duodenal lesions (NADLs). Methods: This retrospective observational study included 84 patients who underwent endoscopic resection (ER) with non-ampullary duodenal lesions, between March 2010 and November 2020, at the Cancer Hospital of the Chinese Academy of Medical Sciences (Beijing, China). Data on patient demographics, therapeutic outcomes, and follow-up results were analyzed. Results: There were 44 patients undergoing EMR, and 40 patients accepting ESD. The overall en bloc resection rate was 98.8% (83/84). For the neoplastic lesions, the overall en bloc resection rate and curative rate were 98.5% (67/68) and 89.7% (61/68), respectively. The procedure-related bleeding and perforation rates were 2.4% and 10.7%, respectively. Univariate analysis results indicated that the main correlation factor of non-curative pathologic resection was tumor size (p = 0.004) and resection size (P < 0.01). There showed a higher curative rate in patients with tumors less than 25 mm in diameter. Multivariate logistic regression analyses determined that the tumor size (OR 0.935; 95% CI 0.878-0.995; P = 0.035) was associated with non-curative resection. No recurrences were observed in patients who had undergone a complete ER during a follow-up period of 42.8 months (range, 3-127 months). Conclusion: Endoscopic resection is an effective, safe, and feasible treatment for non-ampullary duodenal lesions.
