Rebamipide plus proton pump inhibitor versus proton pump inhibitor alone in the treatment of endoscopic submucosal dissection-induced gastric ulcer: a meta-analysis of randomized controlled trials.
Proton pump inhibitor (PPI) was the main prescription for gastric ulcer after endoscopic submucosal dissection (ESD). Some randomized controlled trials showed that a combination of rebamipide and PPI appears to be more efficient than PPI alone for the treatment of ESD-induced gastric ulcer. However, the sample sizes in these trials were limited and the conclusions were underpowered. ⋯ All 5 studies considered scarring stage 1 rate as a primary endpoint, and the scarring stage 1 rate in combination group (115/317) was higher than that in PPI alone group (63/309) (odds ratio 2.61, 95% confidence interval [CI] 1.76-3.88). The mean difference of initial ulcer size between 2 groups was -4.46 (95% CI -266.61 to -257.69, P = 0.97), but it enlarged to 68.38 (95% CI 35.72-101.05, P < 0.00001) in the 4th week. This meta-analysis demonstrates that combination therapy is more efficient than PPI monotherapy in healing ESD-induced gastric ulcer.
