Sequestrated tubular duplications of small bowel.

Duplications of bowel are well-known gastrointestinal tract anomalies. However, sequestrated duplications are very uncommon. Two sequestrated tubular duplications of the small bowel, separate from the ileum with autonomous blood supply and classic histologic features of small bowel are presented. Two sequestrated duplications in the same child are quite rare and have not been previously reported.
