Gastric duplication: Differential diagnosis and treatment|Duplicazione gastrica: Diagnosi differenziale e trattamento

Intestinal duplications are a rare congenital anomaly (0.1-0.3% of all gastrointestinal tract malformations) and the gastric duplications are 2-8% of the cases. Detection of this pathology is often occasional during diagnostic examinations for other diseases or for aspecific symptoms, and more rarely is observed in adulthood. The differential diagnosis with other retroperitoneal diseases or mesenteric cysts is difficult also for the lack of diagnostic suspect. Abdominal ultrasound and CT scan are the 2 examinations of choice. Two cases of gastric duplication which did not communicate with the gastrointestinal tube are reported; surgery has been the treatment of choice due to the possible neoplastic degeneration of the mucosa internal layer and very important for the diagnosis.
