ABSTRACT
BACKGROUND:
Gastric adenomas can be successfully treated with endoscopic resection, including endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR). The aim of this study was to evaluate and compare the efficacy of ESD and EMR with circumferential precutting (EMR-P) in the treatment of small gastric adenomas.METHODS:
This study included 1014 gastric adenomas ≤ 15 mm in diameter treated with ESD or EMR-P from 2012 to 2019, retrospectively. Propensity score matching between the ESD and EMR-P groups (11 to 31) was performed according to age, sex, tumor size, tumor location (upper, middle, and lower thirds), morphology, and preprocedural histology. The procedure time and the rates of en bloc resection, complete resection, adverse events, and local recurrence were compared between the two groups.RESULTS:
After propensity score matching, 478 lesions (ESD 295, EMR-P 183) were analyzed. The rates of en bloc resection (94.9% vs. 93.4%, p = 0.498), complete resection (93.6% vs. 90.2%, p = 0.177), bleeding (8.1% vs. 3.8%, p = 0.063), and local recurrence (0.0% vs. 1.4%, p = 0.185) did not significantly differ between the two groups. The procedure time was significantly longer for ESD than for EMR-P (p < 0.001). In the EMR-P group, the complete resection rate was significantly lower in the upper third than in the middle and lower thirds (p < 0.001).CONCLUSION:
EMR-P is as effective as ESD for the treatment of small gastric adenomas. However, the efficacy of EMR-P is lower for gastric adenomas in the proximal stomach.Palavras-chave
