title: An incarcerated peristomal gastric hernia causing gastric outlet obstruction.
abstract: A 77-year-old woman had had several 3-day episodes of nausea and vomiting for 3 years. Upper endoscopy led to findings consistent with pyloric outlet obstruction, and barium studies demonstrated an incarcerated peristomal gastric hernia. This is taken to be the third description of this diagnosis. We discuss the pathophysiology of gastric hernias.
