have indicated that rebamipide therapy accelerates ulcer
healing. In a multicenter randomized controlled trials (RCT),
rebamipide (Mucosta, Otsuka Pharmaceutical, Tokyo, Japan)
was reported to be efficacious for treating large gastric ulcers
following Helicobacter pylori eradication (4). Another
recent placebo-controlled trial also found that rebamipide is
as effective as omeprazole in treating H. pylori-positive gastric
ulcers after eradication (5). In randomized controlled
studies, rebamipide has been found to prevent nonsteroidal
anti-inflammatory drug (NSAID)-induced peptic ulcers, accelerate
gastric ulcer healing and suppress mucosal inflammation
in patients with chronic erosive gastritis (6, 7). Recently,
several studies (8-14) have examined the efficacy of
rebamipide and PPI combination therapy for the treatment
of ESD-induced ulcers. However, there is currently no consensus
regarding the optimal treatment duration or drug
regimen. Therefore, we conducted a meta-analysis of published
data in order to evaluate the efficacy of PPI plus rebamipide
therapy for successfully treating ESD-induced ulcers.
