[Gastric duplication. A case report and review of the literature]

Duplications of the alimentary tract are rare congenital anomalies. They can occur anywhere throughout the gastrointestinal tract. Gastric duplications represent only 7% of all gastrointestinal duplications. Symptoms and signs often can include vomiting, abdominal pain and palpable mass, and in some cases symptoms related to its complications may be present. The etiology has not been well characterized yet. Although radiographic studies, ultrasonography and computerized axial tomography may help to the preoperative diagnosis, this diagnosis is usually confirmed at surgery. The objective of this paper was to report the case of a 2-year-old girl with recurrent vomiting and abdominal palpable mass with histopathology diagnosis of gastric duplication.
