[Duodenal duplication. Case report and review of the literature]

A case of duodenal duplication (cyst) in a 42-year-old male is reported. The late manifestation of this rare, little-known, but noteworthy congenital malformation was characterized by repeated attacks of acute pancreatitis and development of a high, duodenal obstruction. Radiographic examination and fiberoptic endoscopy was followed by exploratory laparotomy which demonstrated the accurate diagnosis. A review of the literature including 39 duodenal duplications in more than 300 duplications of the alimentary tract is presented.
