Colorectal tubular enteric duplication

Journal of Perinatology volume 29, pages 774–776 (2009)Cite this article

The contrast enema at the time of colonoscopy showed a tubular colorectal duplication communicating with the distal sigmoid proximally and with the rectum at the ‘pit’. The child then underwent a mucosectomy of the enteric tubular duplication and an excision of the common wall between the rectum and the duplication. The mucosal lining that was removed showed a normal colonic mucosa.

Enteric duplications are uncommon anomalies that arise anywhere along the alimentary canal from the tongue to the anus.1 They are of two types, namely spherical cystic and tubular. Approximately 82% of enteric duplications are spherical cysts.1 Duplications are characterized by three criteria developed by Ladd and Gross:2 (1) continuity or adherence to a part of the alimentary tract, (2) a smooth muscle wall and (3) a mucosal lining of one or more cell types typically found in the alimentary canal. The etiology of duplications is uncertain and various etiologies have been proposed, including aberrant luminal recanalization, abortive twinning, persistent embryological diverticula and sequela of split notochord syndrome. None of these satisfactorily account for all duplications. Duplications are most common in the ileum and esophagus, followed in order by the large bowel, jejunum, stomach and duodenum.
