title: Gastric wall ischemia following massive gastric distension due to peptic pyloric stenosis: a case report.
abstract: Gastric necrosis is a rare entity mainly due to the rich collateral blood flow the stomach is supplied by. Acute gastric dilation is one of the described underlying causes, and although not fully understood, many potential alterations, such as vascular compression, herniation, volvulus, acute necrotizing gastritis, complications after abdominal surgery, anorexia, bulimia nervosa, trauma, exposure to caustic materials, diabetes, medications, infections, debilitating chronic illness, gastric outlet obstruction, aerophagia and acute pancreatitis have been described. In this report, we present a case of partial gastric ischemia with necrosis and consequent perforation of the lesser curvature of the stomach, as a result of gastric outlet obstruction due to pyloric stenosis. The patient underwent an emergency laparotomy. An atypical gastrectomy and a Heineke-Mikulicz pyloroplasty were performed. We emphasize the need for the quick recognition of this condition and for the urgent management because of the high mortality rate associated with undiagnosed gastric necrosis.
