Gastric duplication usually presents as gastric outlet obstruction. They are usually spherical in form, do not communicate with the stomach, and are generally localized at the greater curvature. In some cases they may exhibit adhesion to the pancreas and even communicate with aberrant pancreatic ducts. Gastric duplication is more frequent in females. It is generally either diagnosed in infancy because of symptoms of gastric outlet obstruction or is an incidental finding in adulthood.
