Abstract
Background
Vonoprazan exhibits a more potent, rapid, and longer-lasting inhibitory effect on gastric acid secretion than proton pump inhibitors; however, whether it is more effective than PPI for treating endoscopic submucosal dissection (ESD)-induced artificial ulcers remains controversial.
Aim
This study aimed to assess and compare the effects of vonoprazan and lansoprazole for treating ESD-induced artificial ulcers.
Methods
This prospective, randomized controlled trial enrolled 149 patients who underwent ESD for the treatment of early gastric neoplasms from April 2015 to May 2017. They were randomly treated with either 20 mg/day vonoprazan (V group) or 30 mg/day lansoprazole (L group) orally. The primary end points were the area and shrinkage ratio of the ulcers at 4 and 8 weeks post-ESD.
Results
Data from 127 patients were analyzed, which showed that the 4- and 8-week healing ratios were not significantly different between the V and L groups (4 weeks, 16.3 vs. 25.8%; 8 weeks, 86.9 vs. 90.9%, respectively). Similarly, the shrinkage ratio, categorized as less than 90%, 90% or more but less than 100%, or 100% at 4 weeks and as less than 100% or 100% at 8 weeks were not statistically different between the V and L groups (4 weeks: 12, 41, 8 vs. 13, 41, 12, p = 0.7246; 8 weeks: 9, 52 vs. 9, 57, p = 0.8568). Delayed bleeding was also not significantly different between both the groups (5.4 vs. 5.3%; p = 0.9844).
Conclusions
Vonoprazan is as effective as lansoprazole in treating ESD-induced ulcers.
