Intestinal duplications are tubular structures attached to the intestines that share a common blood supply; their lining resembles that of the GI tract.
Intestinal duplications are uncommon. The most common site of duplication is the jejunum and ileum followed by the colon, stomach, duodenum, and esophagus. Colonic duplication is often associated with anomalies of the urogenital system. Intestinal duplications usually manifest in the 1st or 2nd yr of life. Duplications can be asymptomatic or cause obstructive symptoms, chronic pain, or abdominal mass. If they are detected, treatment is surgical with complete resection of the duplicated portion.
