BACKGROUND AND AIMS: We aimed to assess the efficacy of prophylactic mucosal defect closure in reducing delayed adverse events (AEs) after endoscopic resection (ER) of large-to-giant laterally spreading superficial non-ampullary duodenal epithelial tumors (SNADETs).
MATERIALS AND METHODS: We performed a retrospective review of 219 patients with 230 large-to-giant laterally spreading SNADETs who underwent ER at Zhongshan Hospital, Fudan University. The preoperative baseline information, procedure-related AEs and follow-up outcomes were compared between lesions with complete closure and those with incomplete closure or no closure.
RESULTS: The mean maximal diameter was 22.8 ± 13.8 mm (mean ± SD), with 67 lesions (29.1%) ≥ 30 mm. A total of 42 lesions (18.3%) had an occupied circumference ≥ 50%. There were 32 lesions (13.9%) with incomplete closure or non-closure of the mucosal defect. A total of 18 lesions (7.8%) experienced delayed AEs, including delayed perforation in 6 cases (2.6%) and delayed bleeding in 12 cases (5.2%). Lesions with incomplete closure or non-closure had a higher incidence of delayed AEs than lesions with complete closure (34.4% vs 3.5%, P < 0.001). Multivariable regression analyses revealed that incomplete or no mucosal defect closure (OR = 5.154; 95% CI = 1.443-18.405; P = 0.012) and lesions located on the anal side of the major papilla (OR = 11.457; 95% CI = 1.404-93.499; P = 0.023) were independent risk factors for delayed AEs. Lesions with an occupied circumference ≥ 50% (OR = 3.171; 95% CI = 1.024-9.818; P = 0.045) and irregular shape (OR = 5.557; 95% CI = 1.226-25.184; P = 0.026) were independent risk factors for incomplete closure or non-closure.
CONCLUSIONS: Prophylactic mucosal defect closure is an effective technique for reducing delayed AEs after ER of large-to-giant laterally spreading SNADETs.
