Tubular colonic duplication: report of two cases.

Colonic duplication is a rare congenital abnormality frequently associated with multisystemic malformations. Colonic duplication presents diagnostic and therapeutic difficulties especially in neonates. We report on two patients, a child and an adult with tubular duplication. Treatment consisted of using the duplicated loop for a pull-through procedure in the first patient and resection of the duplicated loop in the second. The results of the surgical treatment in these two patients have been satisfactory.
