AbstractProton 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.This meta-analysis was conducted with 5 randomized controlled trials using the combination of rebamipide and PPI for healing ESD-induced ulcer compared with PPI monotherapy. Relevant studies were searched via MEDLINE, PubMed, Embase, and Cochrane Library databases by using terms such as "rebamipide," "proton pump inhibitor," "endoscopic submucosal dissection," "drug therapy," and "gastric ulcer or artificial ulcer."Five studies were included in this meta-analysis. The number of total patients was 626, with 317 patients in the combination group and 309 patients in the PPI alone group. The heterogeneity among these 5 studies was low (I = 22%, P = 0.28). 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.
