ABSTRACT
In the majority of infants born with congenital malformations of the stomach or the duodenum, clinical symptoms become evident during the first few weeks of life, coinciding with feeding and leading to intolerance, vomiting, abdominal distention, and irritability. Microgastria is a rare disorder characterized by a congenitally small stomach that is often accompanied by other anomalies such as malrotation, asplenia, tracheoesophageal fistula and other intestinal anomalies. Gastric duplication is a rare embryologic anomaly of the foregut described as a cystic structure most commonly on the greater curvature of the stomach that does not communicate with the gastric lumen. Radiographic studies with plain radiographs and gastrointestinal barium series will outline an abnormal contour and position of the stomach as well as abnormal position of pylorus in relation to gastroesophageal junction. Radiologic studies demonstrate an abnormal gas pattern, and a barium study outlining the abnormal anatomy and an obstruction can be diagnostic.
