Endoscopic diagnosis of a communicating gastric duplication

A digestive endoscopy was performed in a 13-year-old teenager with halitosis. This examination revealed the presence of a prepyloric orifice with a diverticular aspect. The following radiological exams (OGDT, scanner and RMI) did not guide the diagnosis. Only the ultrasound confirmed the existence of an intramural antropyloric mass, in which there were mucosal gastric, and who communicated with the stomach by one small pertuis. A new endoscopy found prepyloric orifice for the passage of the endoscope but with a quick stop in a multilobed cul-de-sac. After medico-surgical consultation, an intervention by laparoscopy allowed the removal of the lesion. The anatomopathology confirmed the existence of a gastric duplication, with a few pancreatic islets. The postoperative was uneventful and the initial symptoms disappeared. Diagnosis of gastric duplication is usually made by using radiological examinations. In this observation, the endoscopy identified the lesion, confirmed afterwards by the surgical resection.
