Abstract
Artificial ulcers after endoscopic submucosal dissection (ESD) are usually treated by proton pump inhibitors (PPIs) in clinical setting. Vonoprazan, a newly developed potassium-competitive acid blocker, has recently been used to treat post-ESD ulcers. We aimed to evaluate the efficacy and safety of vonoprazan on the healing of post-ESD artificial ulcers compared with those of proton pump inhibitors (PPIs) using a meta-analysis. EMBASE, MEDLINE, Scopus and Cochrane Library databases were searched for all studies comparing the efficacy and safety of vonoprazan with those of PPIs in the treatment of post-ESD ulcers. Fourteen articles with 1328 patients were included in this meta-analysis. When comparing ulcer shrinkage rate, vonoprazan showed a better efficacy than PPIs (mean difference 0.56, 95% confidence interval [CI] 0.18-0.93). Vonoprazan also led to a higher scar formation rate (odds ratio [OR] 1.58, 95% CI 1.00-2.47) and showed a potential superiority on reducing the risk of post-ESD bleeding compared with PPIs, with a pooled OR of 0.69, although there was no statistically significant difference. Compared with PPIs, vonoprazan showed a better efficacy in ulcer shrinkage rate and achieved more complete healing in the treatment of post-ESD ulcers. Vonoprazan did not induce any incremental risk of post-ESD bleeding as well. It may be an appropriate choice in the management of artificial ulcers after ESD.
