Vonoprazan is Superior to Rabeprazole for Healing Endoscopic Submucosal Dissection: Induced Ulcers.
2018
Endoscopic submucosal dissection (ESD) is a well-established minimally invasive treatment for early gastric cancer. To heal ESD-induced ulcers, we commonly prescribe proton pump inhibitors (PPIs). Vonoprazan is our new choice, which is reported to have a stronger and longer acid inhibitory effect than existing PPIs. Here, we aimed to evaluate the efficacy of vonoprazan for healing ESD-induced ulcers compared with rabeprazole.We reviewed 190 patients who underwent ESD before and after we switched the acid secretion inhibitor from rabeprazole to vonoprazan. We evaluated scarring and reduction rates at 4 weeks after ESD.Scarring rates were not different between vonoprazan and rabeprazole (31.7 vs. 18.9%; p = 0.07). However, for ulcers ≤35 mm, vonoprazan was superior to rabeprazole (42.2 vs. 19.2%; p < 0.05). Reduction rates were superior for vonoprazan compared with rabeprazole (93.0 vs. 90.4%; p < 0.05). In multivariate analysis, vonoprazan was superior to rabeprazole for ulcer scarring (OR 2.21; p < 0.05), and ulcer location in the lower-third of the stomach had higher risk of incomplete scarring (OR 0.37; p < 0.05).Vonoprazan was superior to rabeprazole for healing ESD-induced ulcers.
