Abstract
ABSTRACT:
Background: Omphalocele is an uncommon congenital defect in the ventral abdominal wall. Its etiology and pathogenesis are not certainly approved despite the numerous theories.
Cases Description: Two newborn lambs with protruded membranous sacs from the umbilical region were presented. The herniated sac in both lambs contained loops of intestines and covered by a thin membrane. The second lamb's sac was disrupted and its contents were severely congested. Physical and clinical examination of the cases revealed to the congenital omphalocele. An immediate herniorrhaphy was decided for both after failing the gentile reduction of the sacs. All the preparing procedures and the surgical intervention were performed successfully. In the first lamb, the postoperative managements were taken and the animal was completely recovered within two weeks of the operation. However, the second lamb was died shortly after surgery.
Conclusion: Omphalocele is clearly an emerge case which needs an instant treatment. It can have a good prognosis unless the herniated sac was badly manipulated and its contents were sizable and highly congested.
