Congenital intestinal fistula with exomphalos minor.

Minor degrees of exomphalos have been known to be associated with vitellointestinal duct anomalies. The most frequent association is Meckel's diverticulum. It is unusual for a fistula to be communicating directly with the exomphalos sac. We report five neonates that presented with a fistula on the exomphalos sac over a 10-year period. The different variants of patent vitellointestinal duct in these cases have been discussed with a review of the literature.
