A 69-year-old male patient underwent endoscopic submucosal dissection (ESD) of gastric adenoma in May 2012. The pathological diagnosis was tubular adenoma, and curative resection was performed. After ESD, it was thought that Helicobacter pylori was spontaneously eradicated. In April 2014, a 40mm hyperplastic polyp was detected at the resection site. The polyp grew to 50mm in September 2015, at which time we performed ESD of the polyp. However, one year later a similar hyperplastic polyp developed again. We performed ESD of the recurrent polyp and injected 80mg of triamcinolone acetonide locally at the site of the post-ESD ulcer. Thereafter, we have not observed recurrence of polyp. It was considered that local steroid injection prevented the development of hyperplastic polyp at the resection site after ESD.
