Enteric duplication in the adult, derived from the foregut, midgut and hindgut: presentation, patterns and literature review.

Duplication of the alimentary tract may affect patients of all ages. Although they are relatively rare, the importance of these congenital lesions lies in the fact that they readily mimic other surgical disease processes and may result in significant morbidity if left untreated. Prompt recognition and treatment using combined radiologic and surgical management are generally associated with an excellent outcome. Three patients who presented with intestinal duplication arising from each of the major embryologic origins are reported. Their clinical histories reveal the spectrum of presentation associated with these lesions and provide a framework for a discussion of current management strategies.
