Objectives. To review intestinal duplications isolated from the digestive tract.Materials and methods. Description of the 27 isolated intestinal duplication cases published; presentation of a new case.Results. Intestinal duplication isolated from the digestive tract represents an extremely rare malformation. This type of duplication is not in close contact with any segment of the intestinal tract, and it has its own vascular pedicle. Preoperative diagnosis rates are lower than those found in classic duplications. In addition to the potential complications, malformation torsion is also to be considered.Conclusions. This infrequent variant is to be considered at differential diagnosis. Potential torsion should also be taken into account in order to decide when an asymptomatic patient should undergo surgery.
