Secondary closure of large omphalocele using component separation technique: A pediatric case report

Abstract

Introduction and importanceComponent separation technique is utilized in adults to repair large abdominal wall defects but rarely used in children. We report a successfully performed component separation technique in a child after neonatal Gross closure for large omphalocele without biologic mesh placement.Case presentationA 6-year-old girl was treated at the age of 4 days for omphalocele type 2 according to Gross technique. She reconsulted six years later. Clinical examination showed a large eventration measuring 150 ∗ 100 mm. CT scan revealed a broad collar of 150 mm and a large pocket containing liver, transverse colon, stomach and part of the small intestine. The child was proposed for a cure of the eventration using synthetic mesh type GORTEX. Intraoperatively, releasing bowel adhesions with abdominal wall resulted in perforation of the small intestine. Faced with the inability to use the mesh we resorted to abdominal closure with component separation technique. The postoperative was simple without complications or recurrence of the eventration. Follow up was of 4 years.Clinical discussionStaged surgical closure and non-operative delayed closure are the two distinct strategies for managing giant omphaloceles. By providing closure with less intra-abdominal pressure, the Component separation technique is a procedure which can be used in the two strategies. It may minimize the complications associated with large omphalocele management.ConclusionFaced with the impossibility of using a mesh, the component separation technique must be recognized as part of the therapeutic arsenal for secondary closure in children with a giant omphalocele.
