title: Gastric duplication: endoscopic appearance and clinical features.
abstract: The case of a 13-year-old female presenting with a 6 week history of significant vomiting resulting from a gastric duplication is described. At endoscopy, an antral mass which appeared to change in size and site with peristalsis was evident. Although rare, these lesions need to be considered in the differential diagnosis of patients presenting with symptoms suggestive of gastric outlet obstruction. However, in the majority of cases, the diagnosis is rarely made prior to surgery.
