[Duodenal duplication in adults. Laparoscopic treatment].

The authors report a case of duodenal duplication in a adult. This lesion is rare. The clinical course is dominated by a risk of cancer. These lesions should be recognized to avoid a mutilating excision procedure in favour of a conservative procedure. The originality of this case is the laparoscopic approach which confirmed the diagnosis by the elective implantation on the first part of the duodenum. This approach, by mobilisation of the duodenum, allows excision by a very short laparotomy.
