Endoscopic epinephrine injection is relatively easy, quick and inexpensive. Furthermore, it has a low rate of complications, and it is widely used for the management of nonvariceal upper gastrointestinal bleeding. There have been several case reports of gastric ischemia after endoscopic injection therapy. Inadvertent intra-arterial injection may result in either spasm or thrombosis, leading to subsequent tissue ischemia or necrosis, although the stomach has a rich vascular supply and the vascular reserve of the intramural anastomosis. In addition to endoscopic injection therapy, smoking, hypertension and atherosclerosis are risk factors of gastric ischemia. We report a case of gastric ischemia after submucosal epinephrine injection in a 51-year-old woman with hypertension and liver cirrhosis.
