[Gastric duplication. Apropos of a case detected in an adult in a segment from a total gastrectomy].
Gastric duplications are cystic or tubular formations lying in close proximity to the stomach, gastric localizations representing only 3.8% of these digestive malformations of embryologic origin. They should possess walls contiguous with that of the stomach, and a smooth muscle layer fused with that of the stomach, their covering layer being digestive bat not necessarily gastric epithelium. Its presence was discovered fortuitously in a total gastrectomy piece from a patient with adenocarcinoma. The anatomy, diagnostic and treatment of these malformations are discussed.
