    Abstract:
    BACKGROUND: The aim of this study was to analyse different clinical aspects and embryologic hypotheses of duodenal duplications. METHODS: Duodenal duplications occurring since 1995 were recorded. The age of the children at the time of diagnosis, the sex, location of the duplication, type of mucosa, clinical signs, associated lesions, and the type of surgical intervention were defined. RESULTS: We identified 5 patients (3 girls and 2 boys) who presented with histological or intraoperative findings of duodenal duplication. Their ages ranged from 4 days to 9 years, with the exception of two prenatal diagnoses. Three children were symptomatic: high intestinal obstruction (1 case), digestive bleeding (2 cases). In 1 case we found a palpable abdominal mass and 1 case was completely asymptomatic (prenatal detection). The abnormality was located on the duodenal concavity, originating from the third part in 2 cases and from the second part in 3 cases. All cases were non communicating types, 4 of which were cystic duplications and 1 was a tube-like variety. The epithelial lining was duodenal mucosa in all patients, but gastric heterotopies were identified in 2 cases. We performed two complete resections and 3 intraduodenal derivations. The outcome was uneventful in 5 cases with an average follow-up of 2 years. CONCLUSION: Duodenal duplications are rare malformations with several anatomical varieties. The preferred treatment for duodenal duplications is complete removal when the location allows it without endangering nearby anatomical structures.
