Patent omphalomesenteric duct occurs when there is primary failure of luminal closure of
vitellointestinal duct during the fetal life, and it makes an abnormal communication between
the intestine and the umbilicus.
We presented two cases of patent omphalomesenteric duct in the neonatal period.
Diagnosis was confirmed by radiological examination and surgery.
Surgical removal was done successfully.
A brief review of related literature was also presented.
