Completely Isolated, Noncontiguous Duplication Cyst

Abstract

Enteric duplication cysts are hollow, epithelium-lined, cystic, or tubular structures that are intimately attached to a portion of the gastrointestinal tract. Completely isolated duplication cysts are an extremely rare variety of gastrointestinal duplications with their own exclusive blood supply. Only two such previous cases have been reported in the literature so far. We report a third case of completely isolated, giant duplication cyst with a vascular pedicle in a four-day-old neonate with a review of the literature.

Noncommunicating isolated enteric duplication cyst in childhood

“…These usually share a common wall with the normal intestine and have a common blood supply so it is mandatory to remove the adjacent bowel segment along with duplication cyst. This is in contrast to Meckel's diverticulum that occurs on the antimesenteric border of the ileum [1]. In our case, the isolated duplication cyst rested on the mesentery with a separate vascular pedicle and no luminal communication with the adjacent alimentary segments.…”

“…The enteric duplication cyst can be associated with malrotation [8] but not in our case. [1]. The ideal treatment of alimentary tract duplications is complete resection, which is usually accomplished by resection of the adjacent bowel and mesentery.…”

“…Completely isolated duplication cysts are an extremely rare variety of gastrointestinal duplications with their own blood supply and do not communicate with the normal bowel segment [1,2]. We present the first case of such an entity in a 3-year-old female.…”

Completely isolated alimentary tract duplication in a neonate

“…The term alimentary tract duplication is used for congenital lesions having three characteristics: [1] the presence of a well-developed coat of smooth muscle; [2] an epithelial lining representing some portion of the intestinal tract mucosa; and [3] intimate anatomic association with some portion of the gastrointestinal tract [1]. Recently, as we reported in the present case, congenital cystic lesions having gastrointestinal epithelial and wall characteristics without an anatomic association with the alimentary tract have been reported and described as ''isolated duplication'' or ''completely isolated duplication'' of the alimentary tract; eight such cases have been previously reported in the literature [2][3][4][5][6][7]. All but one case was detected and treated during the neonatal period.…”

Report of a rare case and review of adult intestinal duplication at the opposite side of mesenteric margin

“…24 We hypothesized that the course of this case would have begun with repeated duplication of the jejunum, thus resulting in repeated intestinal edema, enlargement and inflammatory changes. At present, the types of imaging that are suggested are ultrasonography, gastrointestinal radiography, computed tomography, radionuclide imaging and magnetic resonance imaging.…”
