Over-the-scope clip closure of gastric endoscopic submucosal dissection-induced ulcer in a patient with bleeding tendency.

A man in his 70s, with a history of dementia and aplastic anemia, was diagnosed with a gastric tumor. Thrombocytopenia due to aplastic anemia may cause bleeding after endoscopic submucosal dissection. Then, ulcer closure using the over-the-scope clip system was performed for prevention of post-operative bleeding.
