Gastrointestinal duplications (GIDs) are rare congenital malformations that consist of cystic or tubular replicas involving any segment of the gastrointestinal tract from the mouth to the anus and containing all three layers. The histologic criteria applied for the diagnosis of GIDs include (1) attachment to a segment of the GI tract, the mesenteric site of which is typically involved and with which they share a common blood supply; (2) a well developed smooth muscle envelope mimicking the normal muscularis propria; and (3) an epithelial lining derived from the alimentary or respiratory tract.
Among the validated theories to define the embryogenesis of GIDs are the fusion of embryological longitudinal folds; persistence of the normal...
