Introduction:
Duplication of the alimentary tract is a relatively rare congenital anomaly. It can affect any part of the gastrointestinal tract, with ileum being the most common site. These malformations are believed to be congenital, formed before the differentiation of epithelial lining, and therefore named for the organ with which they are associated. Duplication cysts of the stomach represent four percent of all alimentary tract duplications.
Case report:
Here, we report a rare case of symptomatic duplication cyst of stomach associated with ectopic pancreas presenting in adult.
Discussion:
Gastrointestinal duplication is a relatively rare anomaly that may occur at any level from oral cavity to rectum with ileum being the most common site. Duplication cysts of the stomach are quite rare, and most of them have been reported in children. Duplication cysts of ileum are usually located on the mesenteric border, whereas the usual location for gastric duplication cysts is along the greater curvature. The duplication cyst is entirely separated from the adjacent bowel but shares a common wall. Complete removal is the treatment choice to avoid the risk of possible complications such as obstruction, torsion, perforation, hemorrhage, and malignancy. A non-communicating GDC is classically treated by complete excision of the cyst and resection of the shared wall between stomach and the duplication cyst.
Conclusion:
This unusual developmental anomaly should be included in the differential diagnosis of cystic masses of the gastrointestinal tract, and the possibility of malignancy should also be considered, so as be treated surgically by complete resection.
