Abstract
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.
