摘　　要：The local injection of triamcinolone acetonide(TA) is effective in preventing pyloric stenosis and deformity following large endoscopic submucosal dissection(ESD).However,because of its long-acting nature,TA can induce long-term local immunosuppression and subsequent adverse events.We report a case of a cytomegalovirus(CMV) ulcer that formed only at the TA local injection site.A 68-year-old man underwent ESD to treat early gastric cancer that formed over the pylorus.The lesion extended to the duodenum,and an artificial ulcer covered more than two-thirds of the circumference of the pylorus.To prevent pyloric stenosis,TA was locally injected into the ulcer floor.On day 12,a deeper ulcer 10 mm in diameter was discovered in the center of the post-ESD ulcer.Biopsies revealed large cells with intranuclear inclusion bodies,which stained positive for the anti-CMV antibody.Local TA injections are useful,however,CMV ulcer might occur as adverse events.The local injection of triamcinolone acetonide (TA) is effective in preventing pyloric stenosis and deformity following large endoscopic submucosal dissection (ESD).
