Hirai A, et al. - This study incorporated an evaluation and comparison of the effects of vonoprazan (V) and lansoprazole (L) for the treatment of endoscopic submucosal dissection (ESD)-induced artificial ulcers in patients with early gastric neoplasms. Experts discovered that 4- and 8-week healing ratios were not significantly different between the V and L groups. Hence, it was deduced that vonoprazan was as effective as lansoprazole in treating ESD-induced ulcers.
