The Usefulness of Argon Plasma Coagulation Compared with Endoscopic Submucosal Dissection to Treat Gastric Adenoma

Background/Aims: To date, the best therapeutic modality for gastric adenoma, especially low-grade adenoma, has not been established. The aim of this study was to assess the usefulness of argon plasma coagulation (APC) in treating gastric adenoma compared with endoscopic submucosal dissection (ESD). Methods: We included 210 patients with gastric adenoma, who underwent treatment with either APC (97 patients) or ESD (113 patients). The clinical and pathologic characteristics, mean duration of hospital stay, complications, and recurrence rates between the two groups were compared. Results: The mean adenoma size was 0.9 cm and 1.1 cm in the APC group and ESD group, respectively (p
