Abstract
BACKGROUND: Endoscopic management of duodenal subepithelial lesions is challenging, and there are only a few studies on this topic. This study aimed to evaluate the safety and efficacy of endoscopic resection for the treatment of duodenal subepithelial lesions. METHODS: We retrospectively analyzed the clinical data, including epidemiologic characteristics, therapeutic outcomes, complications, and follow-up results, of 49 patients with duodenal subepithelial lesions who underwent endoscopic resection at our hospital between August 2010 and September 2019. RESULTS: We performed 35 endoscopic submucosal dissection, 9 endoscopic mucosal resection, 3 endoscopic submucosal excavation, and 2 endoscopic full-thickness resection. The en bloc resection rate and R0 resection rate were 95.9% and 89.8%, respectively. Delayed perforations developed in 2 (4.1%) patients; surgical intervention was required for both. Coagulation syndrome developed in 1 (2.0%) patient; however, it was treated conservatively. Delayed bleeding or other serious complications did not occur. One patient underwent complementary surgery after endoscopic resection. One (2.3%) recurrence occurred in patients who underwent endoscopic resection at a median follow-up duration of 24 months (range, 1-88 months). CONCLUSIONS: Endoscopic resection is an effective, safe, and minimally invasive method for the histopathologic assessment and curative treatment of duodenal subepithelial lesions originating from the submucosal or muscularis propria. 2021 Journal of Gastrointestinal Oncology.
